This article is intended to provide a broad overview of pharmacology and medications often used in either community or institutional pharmacy settings and is not intended as sole means towards determining diagnosis and/or treatment of an individual.

This article will cover the following knowledge areas:

Generic and brand names of pharmaceuticals
Therapeutic equivalence
Drug interactions (e.g., drug-disease, drug-drug, drug-dietary supplement, drug-OTC, drug-laboratory, drug-nutrient)
Strengths/dose, dosage forms, physical appearance, routes of administration, and duration of drug therapy
Common and severe side or adverse effects, allergies, and therapeutic contraindications associated with medications
Dosage and indication of legend, OTC medications, herbal and dietary supplements

Terminology

To get started in this article, there are some terms that should be defined.

pharmacology - The term pharmacology is derived from two Greek words "pharmakon" and "logos". Pharmakon can mean sacrament, remedy, poison, talisman, cosmetic, perfume or intoxicant, but in this case, it can be broadly defined as drug. Logos can be translated as a principle of order and knowledge. By combining the terms you can see that pharmacology is concerned with the knowledge of drugs.

pharmacokinetics - Pharmacokinetics is a branch of pharmacology concerned with the rate of drug absorption, distribution, metabolism, and excretion (ADME) by the body.

over the counter (OTC) - Over the counter medications are drugs that do not require the use of a prescription for a patient to obtain it. These medications are generally considered sufficiently safe for a patient to acquire and self medicate with by following the instructions included on the vial.

behind the counter (BTC) - These are medications that do not require a prescription, but can only be obtained at the pharmacy counter. Examples of this include:

products containing pseudoephedrine,
emergency birth control,
insulins, and
some states allow cough syrups with small amounts of codeine.

legend drug - Legend drugs are medications that require a prescription prior to dispensing. These medications may or may not be considered abusable, but consultation with a medical professional that has prescribing authority is necessary due to the complex health conditions that these medications may be able to treat or ameliorate. Often, you will see the phrase "Rx only" used to denote legend drugs.

controlled substances - Controlled substances are medications with restrictions due to abuse potential. There are 5 schedules of controlled substances with various prescribing guidelines based on abuse potential counter balanced by potential medicinal benefit as determined by the Drug Enforcement Administration and individual state legislative branches.

dietary supplements - A dietary supplement is intended to supply nutrients, (vitamins, minerals/electrolytes, and amino acids) that are missing or not consumed in sufficient quantity in a person's diet. This category may also include herbal supplements.

vaccines - A vaccine is a biological preparation that improves immunity to a particular disease. A vaccine typically contains an agent that resembles a disease-causing microorganism, and is often made from weakened or killed forms of the microbe, its toxins or one of its surface proteins.

brand name - This is the manufacturer's trademark designation. Each brand name is owned by the company and begins with a capital letter, and it is protected by a trademark. Drugs often have several brand names. The terms trade name and proprietary name may also be used interchangeably with brand name.

generic name - This is the official non-proprietary name assigned by the manufacturer with the approval of the USAN (United States Adopted Name) Council. The Federal Food and Drug Administration (FDA) requires that each drug has a generic name, even if currently it is only available as a brand name product. A generic name may also be referred to as the non-proprietary name.

therapeutic equivalents - Drug products are considered to be therapeutic equivalents only if they are available in the same dosage strength, dosage form, achieve the same blood levels, and if they can be expected to have the same clinical effect and safety profile when compared to the original innovator drug. To ensure that a specific generic product is considered to be a therapeutic equivalent, it is recommended that you refer to the Orange Book, a publication from the Food and Drug Administration (FDA). If the products being compared in the Orange Book are considered therapeutic equivalents, it will be given a Therapeutic Equivalence (TE) Code that begins with an "A". If the products are not considered therapeutic equivalents, they will be given a TE Code that begins with a "B". Sometimes these will be referred to as "A" ratings and "B" ratings. These ratings are typically two letters long and will sometimes include a number as well. Usually, a tablet or capsule that is therapeutically equivalent to the innovator drug will have a TE Code 'AB' (with the first letter establishing whether or not the drugs are therapeutically equivalent, and the second letter establishing dosage form category). If a number is included after the two letter code that must also match to be considered therapeutically equivalent.

National Drug Code (NDC) - Each medication is assigned a unique 10-digit, 3-segment number. This number, known as the National Drug Code (NDC), identifies the labeler or vendor, product, and trade package size.

The first 4 or 5 digits indicate the manufacturer
The second 3 or 4 indicate the medication, strength, and dosage form
The third set of numbers always has 2 digits and indicates the package size

classification - This is how a medication is grouped and is typically defined according to its use in treating a particular disease or disorder. A potential source of confusion is that many medications could be grouped multiple ways. An example of this is aspirin, which can be classified as an analgesic, antipyretic, and anti-inflammatory agent.

indication - This is the primary condition(s) treated by a particular drug. This may include both FDA approved uses as well as off-label (generally based on scientific studies but lacking FDA approval) medication uses.

off-label uses - Off-label use is the use of a medication in a manner different from that approved by the FDA including:

for an unapproved indication,
in an unapproved age group,
unapproved dosage, or
unapproved form of administration.

dosage form - A dosage form is the physical form of a dose of medication, such as capsule, patch, or injection. The route of administration is dependent on the dosage form of a given drug. As an example, persistent vomiting may make it difficult to use an oral dosage form; therefore, an antiemetic in suppository form may be desirable.

interactions - Medications have the potential to interact with other medications, dietary supplements, and constituents of various foods. Medications may also interact with various diseases.

contraindication - A contraindication is a condition or factor that serves as a reason to withhold a certain medical treatment.

side effect - A side effect is an effect, whether therapeutic or adverse, that is secondary to the one intended. The term is predominantly employed to describe adverse effects, but it can also apply to beneficial consequences of the use of a drug. A side effect of diphenhydramine (an antihistamine) is drowsiness, which would be an adverse effect if someone needed to be alert, but could be beneficial if they required help going to sleep.

pregnancy category - The pregnancy category of a pharmaceutical agent is an assessment of the risk of fetal injury due to the pharmaceutical, if it is used as directed by the mother during pregnancy. It does not include any risks conferred by pharmaceutical agents or their metabolites that are present in breast milk. The United States FDA has the following definitions for the pregnancy categories:

Pregnancy Category A - Adequate and well-controlled studies have failed to demonstrate a risk to the fetus in the first trimester of pregnancy (and there is no evidence of risk in later trimesters).
Pregnancy Category B - Animal reproduction studies have failed to demonstrate a risk to the fetus and there are no adequate and well-controlled studies in pregnant women OR Animal studies which have shown an adverse effect, but adequate and well-controlled studies in pregnant women have failed to demonstrate a risk to the fetus in any trimester.
Pregnancy Category C - Animal reproduction studies have shown an adverse effect on the fetus and there are no adequate and well-controlled studies in humans, but potential benefits may warrant use of the drug in pregnant women despite potential risks.
Pregnancy Category D - There is positive evidence of human fetal risk based on adverse reaction data from investigational or marketing experience or studies in humans, but potential benefits may warrant use of the drug in pregnant women despite potential risks.
Pregnancy Category X - Studies in animals or humans have demonstrated fetal abnormalities and/or there is positive evidence of human fetal risk based on adverse reaction data from investigational or marketing experience, and the risks involved in use of the drug in pregnant women clearly outweigh potential benefits.

excipient - An excipient is anything in a medication other than its active ingredient. Common categories for excipients include antiadherents, binders, coatings, disintegrants, fillers, flavors and colors, glidants, lubricants, preservatives, sweeteners, and printing inks.

Common medications

Pharmacy technicians should be able to categorize drugs into major therapeutic classifications and be able to briefly describe the therapeutic use of each drug. Technicians should also be able to correlate brand name medications with the generic names.

The following subsections will break the drugs down into various therapeutic classes, with descriptions of these classes followed by a list of generic drug names accompanied by their most common brand names and commercially available dosage forms. These lists are not to be considered comprehensive, but instead just provide some of the more common items to serve as a quick refresher. If you want more information on a particular drug, please using additional drug information resources.

Anti-infective agents

An anti-infective (also called an antimicrobial) is a substance that kills or inhibits the growth of microbes such as bacteria, fungi, protozoans or viruses. In this section we will look at antibiotics, antifungals, amebicides, and antivirals.

Anti-infectives are usually given intermittently for a short period of time (3 to 14 days), although there are exceptions to this.

Antibiotics

This image provides a visual representation of which organelles within a bacteria cell are targeted by various antibiotics.

In common usage, an antibiotic is a substance or compound that kills or inhibits the growth of bacteria. Antibiotics are divided into two main types: bactericidal and bacteriostatic. Bactericidal drugs are actually lethal; that is they actually kill the bacteria. Bacteriostatic drugs inhibit the reproduction (growth) of bacteria. Many antibiotics can be either bacteriostatic or bactericidal based on which bacteria they are being used against and how high a dose is being administered.

Bacteria treated by antibiotics are usually broken into two categories, gram-positive and gram-negative.

Gram-positive bacteria are those that are stained dark blue or violet by Gram staining. This is in contrast to gram-negative bacteria, which cannot retain the crystal violet stain, instead taking up the counterstain (safranin or fuchsin) and appearing red or pink. Gram-positive organisms are able to retain the crystal violet stain because of the high amount of peptidoglycan in the cell wall. Gram-positive cell walls typically lack the outer membrane found in gram-negative bacteria. Many antibiotics are able to work against both gram-positive and gram negative infections.

A useful way of looking at antibiotics is how they function against bacteria cells. The image to the right provides a broad overview as to which organelles various antibiotics target when fighting bacteria.

Penicillin derivatives

Penicillin derivatives act by preventing cell wall synthesis during active replication and are therefore bactericidal. Penicillin derivatives have a chemical structure referred to as a beta-lactam ring, which is what allows it to attach to the bacteria. Penicillins are used in the treatment of bacterial infections caused by susceptible, usually gram-positive, organisms. The most common side effects are allergic reactions including rash, hives, or anaphylactic shock.

Amoxil, Moxatag, Trimox (generic name: amoxicillin [pronounced: am OX i sil in]) - oral suspension, capsule, tablet, chewable tablet, extended-release tablet
Principen (generic name: ampicillin [pronounced:am pi SIL in]) - capsules, oral suspension, powder for injection
Nafcil (generic name: nafcillin [pronounced:naf SIL in]) - injectable solution, powder for injection
Bactocill (generic name: oxacillin [pronounced:ox a SIL in]) - infusion solution, oral solution, powder for injection
Bicillin, Wycillin (generic name: penicillin G [pronounced:pen i SIL in jee ]) - premixed injectable solution, powder for injectable solution
Pen Vee K, Veetids (generic name: penicillin V potassium [pronounced:pen i SIL in vee poe TASS ee um ]) - oral solution, tablet
Pipracil (generic name: piperacillin [pronounced:PI per a SIL in]) - powder for injection

Penicillin derivatives with beta-lactamase inhibitors

Sometimes bacteria become resistant to penicillin. One such mechanism of action for them to do that is by creating beta-lactamase, which breaks down the beta-lactam ring in penicillins preventing them from attaching to the bacteria walls. There is a chemical class that can prevent this called beta-lactamase inhibitors that are often coupled with penicillins.

Augmentin (generic name: amoxicillin & clavulanate [pronounced: am OX i sil in & KLAV yoo LAN ate ]) - oral suspension, tablet, chewable tablet
Unasyn (generic name: ampicillin & sulbactam [pronounced: am pi SIL in & SUL bak tam ]) - injectable solution, powder for solution
Zosyn (generic name: piperacillin & tazobactam [pronounced: pi PER a sil in & ta zoe BAK tam SOW dee um ]) - powder for injection
Timentin (generic name: ticarcillin & clavulanate [pronounced: tye kar SIL in & klav yoo LAN ate]) - powder for injection, infusion solution

Carbapenems

Carbapenems are a class of beta-lactam antibiotics with a broad spectrum of antibacterial activity, and have a structure which renders them highly resistant to beta-lactamases.

Invanz (generic name: ertapenem [pronounced: er ta PEN em ]) - powder for injection
Primaxin (generic name: imipenem & cilastatin [pronounced: IM i PEN em & SYE la STAT in ]) - powder for injection
Merrem (generic name: meropenem [pronounced: mer oh PEH nem ]) - powder for injectable solution

Cephalosporins

The cephalosporins are bactericidal antibiotics that have chemical structures similar to those of penicillins and therefor have the same mechanism of action. Also, due to their similar chemical structure to penicillin, there is a 7-10% potential of cross sensitivity. The cephalosporins are considered to be broad spectrum drugs. Their two main uses are as substitutes for penicillins in cases of allergy or bacterial resistance and in the treatment of certain gram-negative infections.

Ceclor (generic name: cefaclor [pronounced: CEF a klor]) - capsule, tablet extended-release
Kefzol (generic name: cefazolin [pronounced: sef A zoe lin]) - powder for injection
Omnicef (generic name: cefdinir [pronounced: SEF dih neer]) - capsule, oral suspension
Maxipime (generic name: cefepime [pronounced: SEF e peem]) - infusion solution, powder for injection
Claforan (generic name: cefotaxime [pronounced: SEF oh TAX eem]) - injectable solution, powder for injection
Cefotan (generic name: cefotetan [pronounced: SEF oh TEE tan]) - injectable solution, powder for injection
Teflaro (generic name: ceftaroline [pronounced: SEF ta ROE leen]) - powder for injection
Fortaz (generic name: ceftazidime [pronounced: sef TAY zi deem]) - injectable solution, powder for injection
Rocephin (generic name: ceftriaxone [pronounced: SEF trye AX one ]) - injectable solution, powder for injection
Keflex (generic name: cephalexin [pronounced: sef a LEX in]) - capsule, film-coated tablet, oral suspension, tablet for oral suspension

Aminoglycosides

The aminoglycosides are a group of bactericidal antibiotics whose antibacterial spectrum mainly includes gram-negative bacilli. Aminoglycosides have poor oral absorption; therefore, if systemic effects are desired, they are usually given IV or IM. Aminoglycosides are both nephrotoxic (kidney) and ototoxic (ear).

Amikin (generic name: amikacin [pronounced: am E kay sin ]) - injectable solution
Garamycin (generic name: gentamicin [pronounced: gen tah MY sin ]) - injectable solution, ophthalmic ointment, ophthalmic suspension
Kantrex (generic name: kanamycin [pronounced: KAN a MYE sin ]) - injectable solution
Nebcin, Tobi, Tobrex (generic name: tobramycin [pronounced: toe bra MY sin]) - injectable solution, nebulizer solution, ophthalmic ointment, ophthalmic solution
TobraDex (generic name: tobramycin & dexamethasone [pronounced: TOE bra MYE sin & DEX a METH a son]) - ophthalmic ointment, ophthalmic suspension - This is a combination of an aminoglycoside and a corticosteroid.

Tetracyclines

The tetracyclines (a group of broad-spectrum bacteriostatic antibiotics) are clinically useful in both gram-positive and gram-negative infections.

When ingested, it is usually recommended that tetracyclines should be taken with a full glass of water, either two hours after eating or one hour before eating. This is partly because tetracycline binds easily with magnesium, aluminum, iron, and calcium, which reduces its ability to be completely absorbed by the body. Dairy products or preparations containing iron are not recommended directly after taking the drug.

Side effects from tetracyclines are not always common; but of particular note is possible photosensitive allergic reaction, which increases the risk of sunburn under exposure to UV light from the sun or other sources. Tetracyclines are teratogens due to the likelihood of causing teeth discoloration in the fetus as they develop in infancy. For this same reason, tetracyclines are contraindicated for use in children under 12 years of age.

Vibramycin (generic name: doxycycline [pronounced: DOX i SYE kleen ]) - capsule, powder for injection, syrup, tablet, delayed-release tablet
Minocin (generic name: minocycline [pronounced: mye no SYE kleen]) - oral suspension, tablet, capsule, extended-release tablet, intravenous injection
Sumycin (generic name: tetracycline [pronounced: TET tra SYE kleen ]) - capsule, tablet
Tygacil (generic name: tigecycline [pronounced: tye ge SYE kleen ]) - powder for injection

Sulfonamides

Sulfonamides are a group of synthetic bacteriostatic drugs which are effective against both gram-positive and gram-negative infections. Approximately 3% of people using sulfonamides report side effects, the most common of which are hypersensitivity reactions such as rash and hives, but some patients may have more severe reactions.

Sulfonamides have the potential to crystallize in the kidneys due to their low solubility. This is a very painful experience, so patients are recommended to take these medications with large amounts of water.

Silvadene (generic name: silver sulfadiazine [pronounced: SIL ver SUL fa DYE a zeen ]) - cream
Bactrim, Septra, Co-Trimoxazole (generic name: sulfamethoxazole & trimethoprim - sometimes abbreviated as SMZ & TMP [pronounced: SUL fa meth OX a zole & trye METH oh prim]) - injected solution, oral solution, tablet
Azulfidine (generic name: sulfasalazine [pronounced: SUL fa SAL a zeen ]) - tablet, extended-release tablet

Macrolide antibiotics

The term macrolide refers to the large chemical ring structure that is characteristic of these antibiotics. These antibiotics inhibit bacterial protein synthesis and can be bacteriostatic or bactericidal. Food affects oral absorption of these drugs, although they frequently cause GI problems which may warrant taking them with food. Macrolides may interfere with some medications that require liver biotransformation such as digoxin, warfarin, and cyclosporine; therefore, a different antibiotic choice may be desirable if a patient is currently using any of those medications.

Zithromax, Z-Pak, Zmax, AzaSite (generic name: azithromycin [pronounced: a ZITH roe MYE sin]) - oral suspension, powder for injection, powder for oral suspension, extended-release powder for oral suspension, tablet, ophthalmic solution
Biaxin (generic name: clarithromycin [pronounced:kla RITH roe MYE sin]) - oral suspension, tablet, extended-release tablet
Erythrocin, E-Mycin (generic name: erythromycin [pronounced:er ITH roe MYE sin]) - tablet, delayed-release tablet, dispertab, injection, oral suspension, ophthalmic ointment

Fluoroquinolones

The fluoroquinolones, often just called quinolone antibiotics, are synthetic antimicrobial agents that are a broad spectrum bactericidal, especially against gram-negative organisms. A black box warning has been added to all fluoroquinolones involving an increased risk of developing tendinitis and tendon rupture in patients of all ages taking fluoroquinolones for systemic use. This risk is further increased in individuals over 60 years of age, taking corticosteroid drugs, and having received kidney, heart, or lung transplants.

Cipro, Ciloxan (generic name: ciprofloxacin [pronounced: SIP roe FLOX a sin ]) - infusion solution, oral suspension, tablet, extended-release tablet, ophthalmic solution, ophthalmic ointment, otic solution
Levaquin (generic name: levofloxacin [pronounced: LEE voe FLOX a sin ]) - injectable solution, premix infusion solution, oral solution, tablet, ophthalmic solution
Avelox (generic name: moxifloxacin [pronounced: moxi FLOX a sin ]) - injectable solution, tablet, ophthalmic solution
Floxin (generic name: ofloxacin [pronounced: oh FLOX a sin ]) - tablet, ophthalmic solution, otic solution

Miscellaneous antibiotics

Some common antibiotics are the only drugs in their respective classes. The following listed medications are examples of those. These drugs each have their own side effects and precautions; for example, IV use of vancomycin may cause a reaction known as red man syndrome characterized by flushing and/or rash that affects the face, neck, and upper torso.

Azactam (generic name: aztreonam [pronounced: AZ tree oh nam ]) - infusion solution, powder for injection
Cleocin (generic name: clindamycin [pronounced: klin da MYE sin]) - capsule, injectable solution, oral solution, vaginal cream, vaginal suppository
Cubicin (generic name: daptomycin [pronounced: DAP to my sin]) - injectable solution
Zyvox (generic name: linezolid [pronounced: lin EZ oh lid ]) - injectable solution, oral suspension, tablet
Bactroban (generic name: mupirocin [pronounced: mue PIR oh sin]) - cream, topical ointment, nasal ointment
Macrobid, Macrodantin (generic name: nitrofurantoin [pronounced: NYE troe fue RAN toin]) - capsule, oral suspension
Vancocin (generic name: vancomycin [pronounced:VAN koe MYE sin ]) - capsule, injectable solution, powder for injection

Antifungals

An antifungal drug is a medication used to treat fungal infections such as athlete's foot, ringworm, candidiasis (thrush), serious systemic infections such as cryptococcal meningitis, and others.

Antifungals work by exploiting differences between mammalian and fungal cells to kill off the fungal organism without dangerous effects on the host. Unlike bacteria, both fungi and humans are eukaryotes. Thus fungal and human cells are similar at the molecular level. This means it is more difficult to find a target for an antifungal drug to attack that does not also exist in the infected organism. Consequently, there are often side-effects to some of these drugs. Many of these agents are hepatotoxic (liver), and liver function and enzymes must be monitored. It is not uncommon for therapy to last for several months.

Fungizone, Abelcet, AmBisome (generic name: amphotericin B [pronounced:am foe TER i sin BEE]) - powder for injection, injectable lipid complex, cream, lotion, ointment
Lotrisone (generic name: betamethasone & clotrimazole [pronounced:bay ta METH a sone and kloe TRIM a zole]) - cream, lotion - This is a combination of a corticosteroid and an antifungal.
Gyne-Lotrimin, Mycelex (generic name: clotrimazole [pronounced:kloe TRIM a zole]) - troche, vaginal cream, vaginal tablet, cream, topical solution, lotion, powder
Diflucan (generic name: fluconazole [pronounced:floo KOE na zole]) - injected solution, oral suspension, tablet
Mycostatin, Nilstat (generic name: nystatin [pronounced:nye STAT in]) - oral powder, oral suspension, oral tablet, troche, cream, ointment, powder, vaginal tablet
Lamisil (generic name: terbinafine [pronounced:ter BIN a feen]) - tablet, oral granules, cream, topical solution

Amebicides

An amebicide (or amoebicide) is an agent used in the treatment of amoebic infections. Alcohol use should be avoided while taking metronidazole because concurrent use may cause a disulfarim-like reaction (nausea, vomiting, flushing of the skin, tachycardia, and shortness of breath).

Flagyl, MetroCream, MetroGel, MetroLotion (generic name: metronidazole [pronounced:me troe NI da zole]) - capsule, tablet, extended-release tablet, infusion solution, topical gel, topical cream, topical lotion, vaginal gel
Pentam (generic name: pentamidine [pronounced:pen TAM e deen]) - powder for injection, powder for nebulizer solution

Antimalarial drugs

Antimalarial drugs are agents used to prevent and cure malaria. Some antimalarial drugs, such as hydroxychloroquine, are also used to treat conditions like rheumatoid arthritis and lupus. One of the most serious side effects is a toxicity in the eye (this primarily occurs with chronic use).

Plaquenil (generic name: hydroxychloroquine [pronounced:hye drox ee KLOR oh kwin]) - tablet
Qualaquin (generic name: quinine sulfate [pronounced:KWYE nine SUL fate]) - capsule

Antivirals

Antiviral drugs are a class of medication used specifically for treating viral infections. Like antibiotics, specific antivirals are used for specific viruses. They are relatively harmless to the host, and therefore can be used to treat infections. They should be distinguished from viricides, which actively deactivate virus particles outside the body.

Most of the antivirals now available are designed to help deal with HIV (ganciclovir); herpes viruses (acyclovir, ganciclovir, valacyclovir), best known for causing cold sores and genital herpes, but actually causing a wide range of diseases; the hepatitis B and C viruses, which can cause liver cancer; and influenza viruses (oseltamivir). Researchers are now working to extend the range of antivirals to other families of pathogens.

Antiviral drugs work by inhibiting the virus either before it enters the cell, stopping it from reproducing, or in some cases, preventing it from exiting the cell. However, like antibiotics, viruses may evolve to resist the antiviral drug.

Zovirax (generic name: acyclovir [pronounced:a SYE kloe veer ]) - injectable solution, oral suspension, powder for injection, tablet, capsule, topical cream, topical ointment
Cytovene (generic name: ganciclovir [pronounced:gan SYE kloe veer]) - capsule, powder for injection, oral solution, implant, ophthalmic gel
Tamiflu (generic name: oseltamivir [pronounced:os el TAM ih veer]) - capsule, oral suspension
Valtrex (generic name: valacyclovir [pronounced:val a SYE kloe veer]) - tablet

Glucocorticosteroids

Glucocorticosteroids (glucocorticoids, corticosteroids) are steroids used to treat inflammation and various allergic conditions. They are similar to the steroid created in the adrenal cortex, although they could be either from natural sources or synthetically manufactured. As your body naturally produces a glucocorticoid, introducing an exogenous source through medication interferes with your bodies negative feedback loop for production of these steroids. This is why it is often necessary to taper a patient off of a steroid so their body slowly starts creating its own endogenous source of steroids again.

Long term use of glucocorticoids can have the following negative effects: thinning of skin, decrease wound healing, stunting pediatric growth, moon-face, obesity, and diabetes mellitus.

Short-acting steroids

Cortef (generic name: hydrocortisone [pronounced:hye dro KORT i zone]) - tablet, oral suspension, powder for injection, rectal cream, enema, foam, suppositories, topical cream, lotion, gel, topical solution, ointment, pledget

Intermediate-acting steroids

Flovent HFA, Flonase (generic name: fluticasone [pronounced:floo TIK a zone]) - aerosol inhaler, disk inhaler, nasal spray, cream, ointment, lotion
Depo-Medrol, Medrol, Solu-Medrol (generic name: methylprednisolone [pronounced:METH il pred NIS oh lone]) - tablet, injectable suspension, powder for injection
Delta-Cortef (generic name: prednisolone [pronounced:pred NIS oh lone])- oral solution, tablet, ophthalmic suspension, ophthalmic solution
Deltasone (generic name: prednisone [pronounced:PRED ni sone]) - oral solution, tablet
Azmacort, Nasacort AQ, Kenalog (generic name: triamcinolone, TAC [pronounced:trye am SIN oh lone])' - nasal spray, inhalation aerosol, intravitreal injection, cream, ointment, paste, topical spray

Long-acting steroids

Decadron (generic name: dexamethasone [pronounced:dex a METH a sone]) - tablet, injectable suspension, elixir, oral solution, oral concentrate, ointment, ophthalmic solution, ophthalmic suspension, intravitreal implant

Drugs affecting the autonomic nervous system

The autonomic nervous system (ANS) is the portion of the nervous system that regulates cardiac and smooth muscle (involuntary muscles) of the internal organs and glands. The ANS can either increase or decrease the activity of these organs through two subdivisions of the ANS known as the sympathetic and parasympathetic nervous systems. These subdivisions work in opposition to each other. The table below provides a brief list of the results from stimulation (or innervation) of either system.

Results from innervation of the sympathetic and parasympathetic nervous system

Organ/Gland	Sympathetic effect	Parasympathetic effect
Heart	increased heart rate increased force of contraction	decreased heart rate decreased force of contraction
Lungs	bronchodilation	bronchoconstriction
Arteries	vasoconstriction (except for coronary arteries and arteries to skeletal muscles)	does not effect arteries
Digestive system	decrease of GI motility and digestive secretions	increase of GI motility and digestive secretions
Eyes	dilation (mydriasis)	constriction (miosis)
Sweat gland secretion	increase	does not effect sweat glands
Urinary bladder	relaxes	contracts
Genitalia	contracts (ejaculation)	erection

Drugs affecting the sympathetic nervous system

The sympathetic nervous system is part of the autonomic nervous system that tends to act in opposition to the parasympathetic nervous system, by speeding up the heartbeat and causing contraction of the blood vessels. It regulates the function of the sweat glands and stimulates the secretion of glucose in the liver. The sympathetic nervous system, which is usually activated under conditions of stress, causes the 'fight or flight' response.

The sympathetic nervous system can be excited or inhibited through either stimulating or inhibiting adrenergic receptors. These adrenergic receptors are normally stimulated by endogenous norepinephrine, but they can be stimulated by exogenous chemicals of either natural or synthetic origin. These adrenergic receptors can be further broken up into subgroups called alpha-1, alpha-2, beta-1, and beta-2 adrenergic receptors. Excitation of alpha-1 and alpha-2 adrenergic receptors causes contraction of smooth muscle resulting in vasoconstriction of most blood vessels, contraction of sphincter muscles in the GI and urinary tract, and dilation of the pupil of the eye (mydriasis). Stimulation of beta-1 adrenergic receptors cause stimulation of the heart (increased heart rate and force of contraction). Stimulation of beta-2 adrenergic receptors cause bronchodilation. Inhibition (blocking) of these receptors cause the opposite effect to occur.

Let's look at drugs that affect these various receptors.

Adrenergic agonists

These drugs stimulate all the adrenergic receptors to varying degrees and will therefore have the effects related to stimulation of these receptors. This allows these drugs to be used for a multitude of purposes, such as acute hypotension (ephedrine, NE, PE), cardiac arrest (EPI, NE), severe asthma (EPI), bronchodilation (ephedrine), anaphylaxis (EPI), congestion (PE), and can be used to dilate pupils (PE).

ephedrine ([pronounced:e FED rin])- injectable solution
EpiPen, Racepinephrine (generic name: epinephrine, EPI [pronounced: EP i NEF rin ]) - autoinjector, injectable solution, solution for nebulization
Levophed (generic name: norepinephrine, NE [pronounced:nor ep i NEF rin]) - injectable solution
Sudafed (generic name: pseudoephedrine, PE [pronounced:SOO doe ee FED rin]) - tablet, syrup

Alpha-2 adrenergic agonists

Alpha-2 agonists, despite stimulating the alpha-2 adrenergic receptors, actually function against the sympathetic nervous system and sometimes will be classified as sympathetic blocking (sympatholytic) drugs. The net result is a decrease in cardiac output and vasodilation making them useful in the treatment of hypertension.

Catapres, Catapres TTS (generic name: clonidine [pronounced:KLOE ni deen]) - injectable solution, extended-release oral suspension, patch, tablet, extended-release tablet
Tenex (generic name: guanfacine [pronounced:GWAHN fa seen]) - tablet

Alpha-adrenergic blocking agents

Alpha-adrenergic blocking drugs are primarily used to treat benign prostatic hypertrophy (BPH). These medications also cause vasodilation and reduced blood pressure, making them suitable choices for treating hypertension.

Cardura, Cardura XL (generic name: doxazosin [pronounced:dox AY zo sin]) - tablet, extended-release tablet
Flomax (generic name: tamsulosin [pronounced:tam soo LOE sin]) - capsule
Hytrin (generic name: terazosin [pronounced:ter AY zo sin]) - capsule

5-alpha-reductase inhibitors

5-alpha-reductase inhibitors are a group of medications with antiandrogenic activity, and are used in benign prostatic hypertrophy (dutasteride, finasteride), male pattern baldness (finasteride), and female hirsutism (finasteride).

Women that are pregnant or are trying to become pregnant should avoid handling crushed or broken finasteride tablets.

Avodart (generic name: dutasteride [pronounced:doo TAS ter ide]) - capsule
Proscar, Propecia (generic name: finasteride [pronounced:fih NAH steh ride]) - tablet

Beta-adrenergic blocking agents

Beta adrenergic blocking agents are commonly called beta-blockers. By blocking the beta-adrenergic receptors, you can decrease the heart rate and the force of contractions causing a decrease in blood pressure. This means the drugs can treat hypertension, angina pectoris, tachycardia, and arrhythmias. Patients with bronchospastic diseases should, in general, not use beta-blockers as they can cause bronchoconstriction.

Tenormin (generic name: atenolol [pronounced:ah TEN oh lol]) - Tablet
Zebeta (generic name: bisoprolol [pronounced:BIS oh PROE lol]) - Tablet
Coreg, Coreg CR (generic name: carvedilol [pronounced:KAR ve dil ole]) - extended-release capsule, tablet

Drugs affecting the parasympathetic nervous system

The parasympathetic nervous system is part of the autonomic nervous system that tends to act in opposition to the sympathetic nervous system, by primarily regulating body functions during rest, digestion, and waste regulation. Stimulation of the parasympathetic system increases the activity of the gastrointestinal and genitourinary system while decreasing the activity of the cardiovascular system.

Cholinergic drugs

The parasympathetic system is regulated by cholinergic receptors. The naturally occurring chemical that stimulates these receptors is called acetylcholine (ACH). Drugs that mimic ACH are therefor called cholinergic drugs. The conditions treated by this class of drugs varies widely. Donepezil and galantamine are each primarily used to treat Alzheimer's disease, while neostigmine is used to treat myasthenia gravis, and is an antidote for nondepolarizing neuromuscular blocking drugs (a group of drugs often used to create a neuromuscular blockade during surgery).

Razadyne, Razadyne ER (generic name: galantamine [pronounced:ga LAN ta meen]) - tablet, extended-release tablet, oral solution
Prostigmin (generic name: neostigmine [pronounced:nee o STIG meen]) - injectable solution, tablet

Anticholinergic drugs

A naturally occurring chemical that works opposite of ACH is acetylcholinesterase, and therefor drugs that mimic acetylcholinesterase are often referred to as anticholinergic drugs. The conditions treated by this group of drugs also varies widely. Atropine can be used to increase the heart rate, anesthesia premedication, reversal of cholinergic drugs, treatment of GI spasticity, mydriasis, and enuresis treatment. Dicyclomine is typically used to treat GI disorders such as ulcers and colitis. Oxybutynin and tolterodine are typically used in the treatment of overactive bladder.

Skeletal muscle relaxants

Skeletal muscle relaxants are used to treat conditions such as muscle spasticity and to relax muscle tone during surgeries. Medications that block muscle contraction within the spinal cord are referred to as centrally acting skeletal muscle relaxants; conversely peripherally acting skeletal muscle relaxants inhibit muscle contraction at the neuromuscular junction (NMJ).

All patients using skeletal muscle relaxants should avoid additional items that will depress the CNS or impair neuromuscular function such as alcohol, sedatives, and tranquilizers. There is also concern over abuse of these drugs, whether on their own or being used with other medications. Hence, carisoprodol was recently made a schedule IV controlled substance.

Neuromuscular blocking agents

Neuromuscular blocking agents (NMBAs or NMBs), also called peripherally acting skeletal muscle relaxants, are primarily used to prevent muscle contractions during surgeries or procedures where reflexes need to be suppressed (e.g., intubation). They can further be broken into two major subgroups: depolarizing (succinylcholine) and nondepolarizing (cisatracurium, pancuronium, rocuronium, and vecuronium).

Norcuron (generic name: vecuronium [pronounced:VEK ue ROE nee um]) - powder for injection

Centrally acting skeletal muscle relaxants

Centrally acting skeletal muscle relaxants, also called spasmolytics, are primarily used to treat muscle spasms that may be caused by overexertion, trauma, or nervous tension. Baclofen and tizanidine are also used to treat multiple sclerosis.

Anesthetics

An anesthetic is a drug that produces anesthesia, a reversible loss of sensation.

Local anesthetics

Local anesthetics, as their name implies, causes a temporary loss of feeling in a confined area of the body. Local anesthetics can be broken into two major groups: amide local anesthetics and ester local anesthetics. Cocaine is also used as a local anesthetic because despite its abuse potential, it is the only local anesthetic that causes vasoconstriction.

Ester local anesthetics

In general, ester local anesthetics have a short or moderate duration of action.

Solarcaine (generic name: benzocaine [pronounced:BENZ o kane ]) - gel, topical solution, otic solution
cocaine ([pronounced:koe-KANE]) CII - topical solution
Pontocaine (generic name: tetracaine [pronounced:TET ra kane]) - injectable solution, powder for injection, throat spray, ophthalmic solution

Amide local anesthetics

Typically, amide local anesthetics have a long duration of action.

Xylocaine, Lidoderm (generic name: lidocaine [pronounced:LYE doe kane]) - injectable solution, infusion solution, oral solution, topical ointment, topical solution, topical jelly, patch

General anesthetics

While many general anesthetics are available, the most common one for institutional pharmacies to dispense is propofol. Propofol is often used used for induction and maintenance of general anesthesia and ICU sedation for intubated, mechanically ventilated patients.

Diprivan (generic name: propofol [pronounced:PROE po fole]) - injectable solution

Medications for treating psychological conditions

There are numerous neurotransmitters located within the brain, including acetylcholine, norepinephrine, dopamine, and serotonin. These neurotransmitters are responsible for the action and function of the brain. If there is an imbalance in any of these neurotransmitters, it can cause a cascade of problems ranging from sleep disorders to hyperkinesis, from seasonal depression to mental illness. Medications used to treat these conditions are typically either excitatory or inhibitory depending on the nature of the imbalance.

Antipsychotic drugs

Antipsychotic drugs, referred to as neuroleptics, are used to suppress the symptoms of schizophrenia and other psychotic conditions. Antipsychotics are associated with a range of side effects. Approximately two-thirds of patients will discontinue use due in part to adverse effects. Side effects may include acute dystonias, akathisia, parkinsonism, tardive dyskinesia, tachycardia, hypotension, impotence, lethargy, seizures, intense dreams or nightmares, and hyperprolactinaemia. Side effects from antipsychotics can be managed by a number of different drugs. For example, anticholinergics are often used to alleviate the motor side effects of antipsychotics. Some of the side effects will appear after the drug has been used only for a long time. When discontinuing therapy, patients must be tapered off of these drugs.

Clozapine is of particular concern because it can cause agranulocytosis, CNS depression, leukopenia, neutropenia, seizure disorder, bone marrow suppression, dementia, hypotension, myocarditis, orthostatic hypotension (with or without syncope) and seizures. With these severe side effects in mind, each of the manufacturers of clozapine are required to enroll patients taking their medication into a national registry where they will monitor a patient's white blood cell count (WBC) and their absolute neutrophil count (ANC). If the numbers fall below a particular level their therapy may need to be halted and the national registry has a responsibility to report the information to the nonrechallengeable database, that way if a physician goes to place the patient on the medication again the various manufacturers will know they are not allowed as they always need to check new orders for a patient against the nonrechallengeable database. Once listed in the nonrechallengeable database they may never use clozapine again.

Hypnotics

Hypnotics are primarily used to induce and maintain sleep, usually to treat insomnia. There are three major categories of hypnotics: benzodiazepines, barbiturates, and nonbarbiturates. Other medications and substances that cause CNS depression (such as alcohol) should be avoided.

Benzodiazepines

Benzodiazepines are commonly used as anxiolytics, sedatives, hypnotics, anticonvulsants, and skeletal muscle relaxants.

Versed (generic name: midazolam [pronounced:mye DAZ oh lam]) CIV - oral syrup, injectable solution
Restoril (generic name: temazepam [pronounced:te MAZ e pam]) CIV - tablet

Barbiturates

Barbiturates are drugs that act as central nervous system depressants, and can therefore produce a wide spectrum of effects, from mild sedation to total anesthesia. They are also effective as anxiolytics, as hypnotics, and as anticonvulsants. Barbiturates also have analgesic effects; however, these effects are somewhat weak, preventing barbiturates from being used in surgery in the absence of other analgesics.

Luminal (generic name: phenobarbital [pronounced:FEE noe BAR bi tal]) CIV - tablet, elixir, injectable solution

Nonbarbiturate hypnotics

Barbiturates, while strictly considered hypnotics, have been largely replaced by the newer nonbarbiturates for treating insomnia since barbiturates are known to cause a 'hangover' effect.

Sonata (generic name: zaleplon [pronounced: ZAH le plon]) CIV - capsule
Ambien, Ambien CR (generic name: zolpidem [pronounced:zole PI dem]) CIV - tablet, extended-release tablet, sublingual tablet, oral spray

Antidepressants

An antidepressant is a psychiatric medication used to alleviate mood disorders such as major depression and dysthymia and anxiety disorders such as social anxiety disorder.

Antidepressants carry a black box warning that in short-term studies, antidepressants increased the risk of suicidal thinking and behavior in children, adolescents, and young adults.

Tricyclic antidepressants

The tricyclic antidepressants are used primarily in the clinical treatment of mood disorders such as major depressive disorder, dysthymia, and treatment-resistant variants. They are also used in the treatment of a number of other medical disorders, including anxiety disorders such as generalized anxiety disorder, social phobia also known as social anxiety disorder, obsessive-compulsive disorder, and panic disorder, post-traumatic stress disorder, body dysmorphic disorder, eating disorders like anorexia nervosa and bulimia nervosa, certain personality disorders such as borderline personality disorder, attention-deficit hyperactivity disorder, as well as chronic pain, neuralgia or neuropathic pain, and fibromyalgia, headache, or migraine, smoking cessation, tourette syndrome, trichotillomania, irritable bowel syndrome, interstitial cystitis, nocturnal enuresis, narcolepsy, insomnia, pathological crying and/or laughing, chronic hiccups, ciguatera poisoning, and as an adjunct in schizophrenia.

Sinequan (generic name: doxepin [pronounced:DOX e pin]) - capsule, tablet, oral concentrate

Selective serotonin reuptake inhibitors

Selective Serotonin Reuptake Inhibitors (SSRIs) are believed to work by decreasing the central nervous system's neuronal uptake of serotonin (5-HT). While these drugs can be used for a very broad range of things, you will typically see them used for treating moderate to major depression, generalized anxiety disorder, panic disorders, social anxiety, post-traumatic stress disorder, premenstrual dysphoric disorder, and prevention of migraine.

Paxil (generic name: paroxetine [pronounced:pa ROX a teen]) - tablet, extended-release tablet, oral suspension

Serotonin-norepinephrine reuptake inhibitors

Serotonin-norepinephrine reuptake inhibitors (SNRIs) prevent the uptake of neuronal serotonin and norepinephrine and are a less potent inhibitor of dopamine reuptake. The increase in these chemicals is believed to be related to their use in treating depression and anxiety. Duloxetine is also commonly used to treat chronic musculoskeletal pain, diabetic peripheral neuropathic pain, and fibromyalgia.

Miscellaneous antidepressants

The medications in this category have varied mechanisms of action, but all function as antidepressants. Bupropion is also used for seasonal affective disorder, and smoking cessation. Mirtazapine is also used for post-traumatic stress disorder (PTSD). Trazodone is used for a number of things, including aggressive behavior, alcohol withdrawal, insomnia, and prevention of migraine.

Wellbutrin, Zyban (generic name: bupropion [pronounced:byoo PRO pee on]) - tablet, sustained-release tablet, extended-release tablet

Desyrel, Desyrel Dividose (generic name: trazodone [pronounced:TRAZ a done]) - tablet, extended-release tablet

Antianxiety agent, nonbenzodiazepine

While many anxiolytic agents are related to benzodiazepines, one popular alternative is buspirone. It has a high affinity for 5HT1 receptors and a moderate affinity for dopamine D2 receptors. Buspirone is considered to have very little abuse potential; so unlike benzodiazepines, it is not a controlled substance.

BusPar (generic name: buspirone [pronounced:byoo SPYE rone]) - tablet

Partial nicotinic receptor antagonist

Varenicline is used as a smoking cessation aid without actually using any form of nicotine. There is a heightened caution with this drug about suicidal ideation (suicidal thoughts). Also, many patients using this medication report abnormal dreams.

Chantix (generic name: varenicline [pronounced:ver EN e kleen]) - tablet

Amphetamines

Amphetamines are commonly used to treat attention deficit hyperactivity disorder (ADHD) and narcolepsy. Their ability to improve focus/concentration and boost energy levels has made this class of drugs very desirable for abuse; therefore, all amphetamines are considered schedule II controlled substances. Side effects may consist of severe weight loss; also, dependence may develop during use of this drug. Amphetamines have the potential to raise the heart rate to dangerous levels.

Adderall, Adderall XR (generic name: amphetamine & dextroamphetamine [pronounced:am FET a meen and DEX troe am FET a meen]) CII - tablet, capsule, extended-release capsule

Other ADHD treatment agent

Atomoxetine is used to treat ADHD. It functions as a selective inhibitor of presynaptic norepinephrine transport. Unlike amphetamines used to treat ADHD, atomoxetine is considered to have little or no abuse potential.

Strattera (generic name: atomoxetine [pronounced:AT oh mox e teen]) - capsule

Anorexiant

Phentermine is indicated as a short-term (a few weeks) adjunct therapy for weight reduction based on increased exercise, behavior modification, and calorie reduction.

Adipex P (generic name: phentermine [pronounced:FEN ter meen]) CIV - tablet, orally-disintegrating tablet, capsule

Stimulant

Modafinil may increase dopamine in the brain by decreasing dopamine reuptake. Modafinil is used for treating narcolepsy, shift work sleep disorder, Obstructive Sleep Apnea/Hypopnea Syndrome (OSAHS), and off label it is used to treat fatigue in MS patients and for depression.

Provigil (generic name: modafinil [pronounced:moe DAF i nil]) CIV - tablet

Antimanic drug

Lithium is one of the oldest medications on the market for treating mania and is still quite popular. Lithium is also sometimes used to treat Huntington's disease, neutropenia (due to chemotherapy, or AIDS), cluster headache, PMS, bulimia, alcoholism, syndrome of inappropriate antidiuretic hormone secretion (SIADH), tardive dyskinesia, hyperthyroidism, and psychosis (postpartum or steroid-induced).

Lithium works by altering cation transport in nerve and muscle cells, and influences serotonin and/or norepinephrine reuptake.

Many of the antiepileptic drugs discussed later in this article are also often used as mood-stabilizing drugs.

Eskalith, Lithobid (generic name: lithium [pronounced:LITH ee um]) LiCO3 - tablet, extended-release tablet, capsule, syrup

NMDA antagonist

N-methyl-D-aspartate (NMDA) antagonists prevent excessive stimulation of the NMDA-receptor, which is ordinarily stimulated by glutamate. At normal levels, glutamate aids in memory and learning, but if levels are too high, glutamate appears to overstimulate nerve cells, killing them through excitotoxicity.

Memantine has been associated with a moderate decrease in clinical deterioration with only a small positive effect on cognition, mood, behavior, and the ability to perform daily activities in moderate to severe Alzheimer's disease. There does not appear to be any benefit in mild disease.

Namenda (generic name: memantine [pronounced:meh MAN teen]) - tablet, extended-release capsule, oral solution

Antiepileptic drugs

Antiepileptic drugs (AEDs) will also sometimes be referred to as anticonvulsants. All of the drugs in this category can be used for treating various types of seizures. Many of these medications have additional uses such as treating trigeminal neuralgia (carbamazepine), bipolar disorder (carbamazepine, lamotrigine, valproic acid), postherpetic neuralgia (gabapentin, pregabalin), muscle cramps (gabapentin), anxiety (gabapentin), diabetic neuropathy (gabapentin, pregabalin), fibromyalgia (pregabalin), neuropathic pain with spinal cord injury (pregabalin), migraine prophylaxis (topiramate, valproic acid), cluster-headache prophylaxis (topiramate), and alcoholism (topiramate).

Antiparkinson drugs

Parkinson's disease is a common neurologic disorder affecting approximately 1% of the population over the age of 60 (a much smaller percentage of the population will sometimes have this disease at an earlier age) caused by the loss of dopamine receptors. This disease presents a number of motor and nonmotor symptoms related to the loss of dopamine receptors.

Typically, the first motor symptom is a resting tremor in an upper extremity. Over time, additional motor symptoms occur including bradykinesia, rigidity, and gait difficulty. The first affected arm may not swing fully when walking, and the foot on the same side may scrape the floor. As the disease progresses, posture becomes increasingly flexed and strides become shorter causing a shuffling motion from the patient.

Nonmotor symptoms usually begin with the loss of smell, and is followed by rapid eye movements and behavior disorders. The most common treatment is the use of carbidopa & levodopa to provide dopamine replacement therapy. Dopamine agonists (pramipexole, ropinirole) are also useful in decreasing the symptoms.

Dopamine agonists (pramipexole, ropinirole) are also useful in the treatment of restless leg syndrome.

Analgesics

An analgesic is simply a medication that provides relief from pain whether through the reduction of inflammation or through a dissociative effect where the patient no longer notices the pain. The word analgesic is derived from Greek where an- is a prefix meaning without, algesia or algos simply means pain, and -ic is a suffix that means pertaining to. Placing the whole word together means pertaining to without pain.

Opioid analgesics

Opioid analgesics are often used to treat acute pain (such as postoperative pain), and for palliative care to alleviate the severe chronic, disabling pain of terminal conditions such as cancer, and sometimes for degenerative conditions such as rheumatoid arthritis. There has been an increased use of opioids in the management of nonmalignant chronic pain. Opioids also have antitussive and antidiarrheal effects; therefore, low doses and or weaker forms of these medications will sometimes be used for those purposes as well. These medications do have a potential for abuse due to their addictive nature. While addictive themselves, two of these medications (buprenorphine & naloxone and methadone) can be used to treat opioid addiction. Most of these medications are considered controlled substances and their federal schedules are listed beside them.

Non steroidal anti inflammatory drugs

Nonsteroidal anti-inflammatory drugs, usually abbreviated to NSAIDs, are a class of drugs that provide analgesic and antipyretic effects, and, in higher doses, anti-inflammatory effects. NSAIDs are usually indicated for the treatment of acute or chronic conditions where pain and inflammation are present, such as rheumatoid arthritis, osteoarthritis, ankylosing spondylitis, gout, dysmenorrhoea, headache and migraine, postoperative inflammation, muscle stiffness, and fever.

Miscellaneous nonopioid analgesics

Some medications do not easily fit into other categories, such as acetaminophen, aspirin and some of the combination analgesics that contain weak barbiturates.

Acetaminophen, sometimes listed as APAP, is a potent analgesic and antipyretic activity with weak anti-inflammatory activity. Acetaminophen-containing products pose a potential to harm liver function; therefore, patients are not to exceed a cumulative dose of 4 g/day of acetaminophen. In January 2011, the FDA mandated that all manufacturers limit acetaminophen in prescription products to 325 mg/dosage unit; manufacturers were required to comply by January 14, 2014.

Aspirin, sometimes listed as ASA, inhibits the synthesis of prostaglandin by cyclooxygenase; inhibits platelet aggregation; and has antipyretic and analgesic activity. While aspirin could technically be classified as a NSAID, it is more often classified as a salicylate.

One thing that surprises many about the combination of butalbital, acetaminophen, and caffeine is that it is not federally scheduled even though the combination of butalbital, aspirin, and caffeine is considered a controlled substance.

Medications affecting the cardiac system

The word cardiac is derived from the Greek word kardia which simply means heart. The cardiac system is the entire system supporting the heart including the cardiac muscle, its conduction system, and the nerve supply along with the rest of the circulatory system such as arteries, aterioles, capillaries, venules, and veins. Many other organs also interact very directly with the cardiac system such as the lungs and kidneys. The medications affecting the cardiac system work by either exciting or inhibiting various functions either in this system or through other organs that interact with the cardiac system.

Besides the medication categories listed in this section (cardiac glycosides, diuretics, antiarrhythmics, angiotensin-II receptor antagonists, angiotensin-converting enzyme inhibitors, calcium channel blockers, nitrates, renin-inhibitors, anticoagulants, antiplatelet medications, and various antihyperlipidemic drugs) some of the categories previously discussed have significant affects on the cardiac system particularly the various medications that effected the sympathetic nervous system.

Cardiac glycosides

Cardiac glycosides are drugs used in the treatment of congestive heart failure and cardiac arrhythmia. Any medications in this category work by increasing the forcing of contraction of the heart, providing an overall increase in cardiac output.

Lanoxin (generic name: digoxin [pronounced:di JOX in]) - elixir, tablet, injectable solution

Diuretics

A diuretic elevates the rate of urination which removes fluid from the body and has a net result of decreased blood pressure. There are various mechanisms of action for these diuretics. Loop diuretics, such as bumetanide and furosemide, inhibit the reabsorption of sodium and chloride ions in the ascending loop of Henle within the kidneys' nephrons. By decreasing this reabsorption, an increased amount of fluid is excreted. Thiazide diuretics, such as chlorothiazide and hydrochlorothiazide (often abbreviated HCTZ), inhibit sodium reabsorption in distal renal tubules resulting in increased excretion of sodium and water. Loop diuretics and thiazide diuretics also cause patients to lose a lot of potassium. Potassium sparing diuretics, such as spironolactone and triamterene, have an effect on renal distal tubules to inhibit sodium reabsorption causing the excretion of sodium and water but allows for the retention of potassium.

Angiotensin-converting enzyme inhibitors

Angiotensin-converting enzyme inhibitors (ACE inhibitors) causes dilation of blood vessels which results in lower blood pressure. In treating heart disease, ACE inhibitors are usually used with other medications. A typical treatment plan will often include an ACE inhibitor, beta blocker, a long acting nitrate, and a calcium channel blocker in combinations that are adjusted to the individual patient's needs.

Calcium channel blockers

These drugs are used to treat hypertension. Calcium channel blockers work by inhibiting the influx of calcium ions into myocardial and vascular tissues thereby preventing contractions and causing the dilation of the main coronary and systemic arteries.

Patients should avoid grapefruit and its constituents while taking calcium channel blockers. Grapefruit inhibits an isoenzyme called CYP3A4 that helps breakdown calcium channel blockers. Inhibiting this enzyme causes patients to effectively be overdosed by their calcium channel blockers. Interactions related to grapefruit are often referred to as grapefruit juice drug interactions (GJDI).

Nitrates

Nitrates relax smooth muscle via dose-dependent dilation of arterial and venous beds to reduce both preload and afterload, and myocardial oxygen demand. Nitrates also improve coronary collateral circulation, lowers blood pressure, and increases heart rate. Nitrates are used for both the relief and prevention of angina pectoris, treatment of perioperative hypertension, control of congestive heart failure during a myocardial infarction, and you will see these used off label for the treatment of anal fissures. Typically, patients need a nitrate free interval to minimize tolerance. This nitrate free interval is often provided at night.

Nitroglycerin also has special storage requirements due to its relative reactivity with certain plastics. As a result, the sublingual tablets should be stored in glass; typically, this means that patients should keep them in their original container from the manufacturer. Also, the nitroglycerin intravenous solution is infused with special tubing to prevent the drug from leaching into the plastic of most infusion sets.

Renin inhibitor

A renin inhibitor prevents the conversion of angiotensinogen to angiotensin I. The decrease in antiotensin I causes a decrease in angiotensin II, a potent blood pressure elevating peptide. This makes renin inhibitors effective in the treatment of hypertension.

Tekturna (generic name: aliskiren [pronounced:a LIS ke rin]) - tablet

Combination antihypertensive agents

Many antihypertensive medications are provided in combinations in order to combine effects and improve patient compliance by decreasing the number of medications the patient may need to take. As all the medications listed below have already been discussed in this chapter, you may refer to the previous information concerning each active ingredient within the combination medications listed below.

Anticoagulants and antiplatelet agents

A broad range of chemicals with various mechanisms of action fall into this category. Anticoagulants and antiplatelet drugs are used for the following treatments: prophylaxis after a myocardial infarction or stroke (aspirin & dipyridamole, clopidogrel, warfarin), acute coronary syndrome (clopidogrel, heparin), peripheral arterial disease (clopidogrel), coronary artery disease (clopidogrel), stenting (clopidogrel), atrial fibrilation (dabigatran, rivaroxaban, warfarin), thromboembolism (dabigatran, dalteparin), deep vein thrombosis (dalteparin, enoxaparin, heparin, rivaroxaban, warfarin), pulmonary embolism (heparin, rivaroxaban, warfarin), unstable angina (dalteparin, enoxaparin, heparin), anticoagulation therapy (dalteparin, heparin), catheter patency (heparin), cardiac valve replacement (warfarin).

Medication interactions are a common concern with these drugs as many pain relievers (most NSAIDs and aspirin) may slow a patient's clotting time. These pain relievers should not be taken in combination with the various anticoagualant and antiplatelet drugs without first consulting a physician.

Warfarin also provides a significant food-drug interaction. Warfarin prevents coagulation by binding vitamin K; therefore foods rich in vitamin K (such as dark leafy greens, broccoli, and asparagus) should be avoided as they will interfere with warfarin.

Below is a short list of the most common anticoagulants and antiplatelet agents.

HMG-CoA reductase inhibitors

HMG-CoA reductase inhibitors (commonly referred to as statins) block the pathway for synthesizing cholesterol in the liver. This is significant because most circulating cholesterol comes from internal manufacture rather than the diet. When the liver can no longer produce cholesterol, total levels of cholesterol in the blood will fall, particularly LDL-cholesterol and triglycerides. They also increase "good cholesterol" -- HDL cholesterol. Cholesterol synthesis appears to occur mostly at night, so statins with short half-lives are usually taken at night to maximize their effect. The most common adverse side effects are raised liver enzymes and muscle problems (most frequently muscle cramps).

Patients should avoid grapefruit and its constituents while taking HMG-CoA reductase inhibitors. Grapefruit inhibits an isoenzyme called CYP3A4 that helps breakdown HMG-CoA reductase inhibitors. Inhibiting this enzyme causes patients to effectively be overdosed by their HMG-CoA reductase inhibitors. Interactions related to grapefruit are often refereed to as grapefruit juice drug interactions (GJDI).

Antihistamines

An allergy is a hypersensitivity to a substance (an allergen) that is normally harmless. Allergy sufferers may endure a wide variety of symptoms such as inflammation of the nasal passages and the conjunctiva (a membrane covering the white part of the eye), skin conditions such as hives and eczema, and asthma attacks. Some allergic conditions can be more serious and even involve anaphylaxis! Exposure to allergens that an individual has become sensitive causes their bodies to release histamines. Patients that desire symptomatic relief may use antihistamines and decongestants.

Antihistamine

Antihistamines are commonly used for the relief of various allergic reactions including allergic rhinitis, perennial & seasonal allergies, pruritus, and allergic conjunctivitis. First generation antihistamines (diphenhydramine and hydroxyzine) can cross the blood brain barrier. As a result, diphenhydramine may be used to treat insomnia, and hydroxyzine may be used to treat nausea and vomiting.

Antihistamines with decongestants

Patients with either colds or congestion related to their allergies may desire an antihistamine in combination with a decongestant. Since pseudoephedrine is the most commonly included decongestant, many of the medications need to be kept behind the counter in order to limit their availability. This is a result of the Combat Methamphetamine Epidemic Act, an act intended to decrease the number of clandestine methamphetamine labs in the United States.

Respiratory medications

Some patients may have respiratory conditions such as asthma or bronchitis. Patients may receive glucocorticosteroids, bronchodialators, leukotriene receptor antagonists, or even epinephrine to treat or prevent acute episodes. Glucocorticosteroids and epinephrine have already been discussed in this article; therefore, this section will focus on bronchodialators and leukotriene receptor antagonists.

Bronchodialators

A bronchodilator is a substance that dilates the bronchi and bronchioles, decreasing resistance in the respiratory airway and increasing airflow to the lungs. The bronchodialators on this list can be further broken down into beta-2 agonists (albuterol, levalbuterol, and salmeterol) and anticholinergics (ipratropium and tiotropium). Fluticasone, which may be used on it own or in combination with other drugs, is classified as a glucocorticosteroid.

Medications for treating diabetes mellitus

This image provides a visual representation of endogenous insulin production in a healthy individual that eats three meals a day.

Diabetes mellitus refers to a group of diseases that affect how your body uses blood glucose, commonly called blood sugar. There are two primary types of this disease: type 1 diabetes and type 2 diabetes.

Type 1 diabetes, also known as insulin dependent diabetes mellitus (IDDM) or juvenile diabetes, typically appears during childhood or adolescence. Individuals with type 1 diabetes require insulin therapy as their bodies do not produce insulin.

Type 2 diabetes, also known as non-insulin dependent diabetes mellitus (NIDDM), usually occurs in adults. Individuals with type 2 diabetes either don't produce enough insulin or their cells have become insulin resistant. These patients will usually receive non-insulin therapies, although they may receive insulin therapy, or even a combination of insulin and non-insulin therapies.

Insulins

This image provides a visual representation of how insulin injections can be used to mimic endogtenous insulin secretions.

Insulin therapy is required in type 1 diabetes, and may be necessary in some individuals with type 2 diabetes. The general objective of insulin replacement therapy is to approximate the physiological pattern of insulin secretion. This requires a basal insulin throughout the day, supplemented by prandial insulin at mealtime. Insulin injections are intended to mimic the natural process, as shown in the image on the right.

A combination of rapid-acting (insulin aspart, insulin glulisine, insulin lispro) or short-acting (insulin regular) given in combination with either an intermediate-acting (insulin NPH) or long-acting (insulin detemir, insulin glargine) insulin are typically used. Sometimes an insulin vial or prefilled syringe may have a mixture of insulins (insulin aspart protamine & insulin aspart, insulin lispro protamine & insulin lispro, insulin NPH & insulin regular human) to help reduce the number of injections a patient requires.

Antineoplastic agents and monoclonal antibodies

Antineoplastics and monoclonal antibodies are types of chemotherapy. Chemotherapy is the use of medications to kill cancer cells. Chemotherapy is used for diffuse tumors and is used after surgery and irradiation of solid tumors in the attempt to eliminate remaining cancer cells that have metastasized.

Antineoplastic agents

Antineoplastic agents are primarily concerned with inhibiting uncontrolled new cell growth (cancer). The following is a table intended to give a succinct list of which antineoplastic agents can be used to treat various cancers. This list is not considered complete, but focuses on the antineoplastic agents discussed in this article.

Sometimes these antineoplastic agents are used for diseases other than cancer. Bleomycin can be used for pleural sclerosing. Cyclophosphamide can be used for nephrotic syndrome, juvenile idiopathic arthritis, lupus nephritis, and systemic sclerosis. Methotrexate can be used psoriasis and rheumatoid arthritis.

A quick pictorial representation of the cell cycle and when each class of antineoplastic agents work during the cell cycle.

These drugs often work during specific phases of the cell cycle as depicted in the image.

Unfortunately, antineoplastic agents can not differentiate between cancer cells and healthy cells which is responsible for many of the common side effects from these treatments as there is rapid cell growth in bone marrow, the GI tract, hair follicles, and skin cells. This often results in anemias, nausea, vomiting, diarrhea, hair loss, photosensitivity, and thinner skin. Many of these medications also have their own unique adverse effects.

Alkylating agents

These medications are considered phase non-selective for when they work; therefore, they work during all phases, except for the G₀ phase.

Besides the broad grouping of side effects common to antineoplastic agents, these drugs have the following side effects as well: carboplatin causes delayed thrombocytopenia; cisplatin has ototoxicity and can cause renal damage; cyclophosphamide can cause hemorrhagic cystitis; oxaliplatin has neurotoxicities, renal toxicity, and can trigger hypersensitivity reactions.

Anthracyclines

These medications are considered phase non-selective for when they work; therefore, they work during all phases, except for the G₀ phase.

Besides the broad grouping of side effects common to antineoplastic agents, they can cause stomatitis and have cardiotoxicities. These drugs are also considered vesicants.

Hormone antagonists

Tumors that involve the reproductive organs (breast, ovaries, uterus, prostate and testes) are often hormone-dependent. The hormones that are often responsible for developing and maintaining these organs are now functioning as growth factors for these cancerous cells. Hormone antagonists can be useful in the treatment of these cancers. Hormone antagonists tend to work best during the G₁ phase by pushing these cancer cells into the G₀ phase.

These medications are often used in combination with surgery and/or radiation therapy.

Many of the side effects from other chemotherapies are not as severe or are often absent.

GnRH agonists

Lupron (generic name: leuprolide [pronounced:LOO proe lide]) - solution for injection, prefilled syringe

Monoclonal antibodies

Monoclonal antibodies, often referred to as targeted therapy, only works against specific cells. To take that a step further, they only react with specific epitopes or antigens. This can reduce or even eliminate many of the side effects, but the medications tend to be very limited as to which cancers and autoimmune diseases they can treat. This is a result of monoclonal antibodies being monospecific antibodies that are all identical, because they are made by immune cells that are all clones of a unique parent cell. This specificity can also be problematic if the antigen becomes minimally changed.

The following table lists the types of cancers that can be treated by monoclonal antibodies.

Type of cancer	Monoclonal antibody that may be used
breast cancer	bevacizumab, trastuzumab

Miscellaneous drug categories

There is a wide array of medications with just a few medications in each category. This section provides information on various common medications that could not be grouped into previous sections.

Hemopoietic agents

These medications affect the hemopoietic stem cells in bone marrow causing an increase in either red blood cells (darbepoetin, epoetin), white blood cells (filgrastim), or platelets (oprelvekin). Dialysis, chemotherapy, and various other causes of anemia make this class of medications extremely useful.

Gouty arthritis treatment

Gouty arthritis is painful inflammation (often of the big toe and foot) resulting from elevated levels of uric acid in the blood and the deposition of urate crystals around the joints. This disease has a greater occurrence in men. The condition can become chronic and result in deformity.

Allopurinol, azathioprine, and colchicine can all be used to treat gouty arthritis. Allopurinol is also used to treat antineoplastic induced hyperuricemia. Azathioprine can also be used for prevention of kidney transplant rejection, rheumatoid arthritis, lupus nephritis, Behcet's syndrome, Crohn's disease, myasthenia gravis, and multiple sclerosis. Colchicine can also be used for familial Mediterranean fever, and Behcet's syndrome.

Enbrel (generic name: etanercept [pronounced:ee TAN er sept]) - injectable solution, prefilled syringe

PDE-5 inhibitors

A phosphodiesterase type 5 inhibitor (PDE-5 inhibitor) is a drug used to block the degradative action of phosphodiesterase type 5 on cyclic GMP in the smooth muscle cells lining the blood vessels supplying the corpus cavernosum of the penis. These drugs are used in the treatment of erectile dysfunction, and were the first effective oral treatment available for the condition. Because PDE-5 is also present in the arterial wall smooth muscle within the lungs, PDE-5 inhibitors have also been used in the treatment of pulmonary hypertension, a disease in which blood vessels in the lungs become overloaded with fluid, usually as a result of failure of the left ventricle of the heart.

Antitussives and expectorants

A cough medicine is a medication used in an attempt to treat coughing and related conditions. For dry coughs, treatment with cough suppressants, antitussives (benzonatate, codeine, dextromethorphan), may be attempted to suppress the body's urge to cough. However, in productive coughs (coughs that produce phlegm), treatment is instead attempted with expectorants (guaifenesin) to loosen mucus from the respiratory tract.

Dietary supplements

Medications, biological agents, and injectables are heavily regulated by the Food and Drug Administration (FDA), whereas dietary supplements intended for oral consumption are only regulated as food by the FDA. To learn more about how dietary supplements are regulated, you may want to review pertinent information from the Dietary Supplement Health and Education Act.

A dietary supplement is intended to supply nutrients, (vitamins, minerals/electrolytes, and amino acids) that are missing or not consumed in sufficient quantity in a person's diet. This category may also include herbal supplements. Dietary supplements often make health related structure function claims.

Micronutrients

A micronutrient is a substance needed only in small amounts for normal body function (vitamins and minerals); as opposed to macronutrients (fats, proteins, and carbohydrates) which are required in much larger quantities.

Vitamins

Vitamins can be defined as any organic compounds that are essential, in small quantities, for the normal functioning of metabolism in the body. They cannot usually be synthesized in the body but they occur naturally in certain foods. Insufficient supply of any particular vitamin results in a deficiency disease, hence the common need for vitamin supplements. Vitamins A, D, E, and K are fat soluble and therefore can be stored in adipose tissue. All other vitamins are considered water soluble.

Vitamin K1 can be used as an antidote for warfarin.

Electrolytes

Electrolytes when dissolved in solution break apart into ions (anions and cations). The movement of these ions across cell membranes are intended to create an electrolyte balance between both the extracellular and intracellular environments. In particular, the maintenance of precise osmotic gradients of electrolytes is important. Such gradients affect and regulate the hydration of the body as well as blood pH, and are critical for nerve and muscle function.

Zinc is also used to topically treat diaper rash and various topical irritations. Some oral types are used to ameliorate cold symptoms.
Multitrace, M.T.E. multiple trace elements - injectable solution - Multiple trace elements are used to provide various trace elements in a parenteral infusion.

Herbals

Herbal supplements are often used for an array of purposes. A common challenge to the use of herbal supplements is the lack of scientific studies for their use; however, there is a plethora of anecdotal evidence (although, sometimes the anecdotal evidence can be conflicting). The following is a brief list of the most commonly used herbal supplements, along with what they are used for. Acknowledgement of their use for the proceeding purposes does not mean that their is sufficient scientific evidence to assure that these supplements will achieve the desired effects.

chondroitin - Chondroitin is often used for osteoarthritis, particularly of the knee.
coenzyme Q10, CoQ10 - Coenzyme Q10 is used to treat angina, chronic fatigue syndrome, CHF, diabetes mellitus, doxorubicin-induced cardiotoxicity (prevention), HIV/AIDS immunostimulant, hypertension, mitochondrial cytopathies, muscular dystrophies, myopathy (statin-induced).

Vaccines

A vaccine is a biological preparation that improves immunity to a particular disease. A vaccine typically contains an agent that resembles a disease-causing microorganism, and is often made from weakened or killed forms of the microbe, its toxins, or one of its surface proteins. The agent stimulates the body's immune system to recognize the agent as foreign, destroy it, and "remember" it, so that the immune system can more easily recognize and destroy any of these microorganisms that it later encounters. Vaccines do not guarantee complete protection from a disease. The efficacy or performance of the vaccine is dependent on a number of factors, including the disease itself (for some diseases, vaccination performs better than for other diseases); the strain of vaccine (some vaccinations are for different strains of the disease); whether one kept to the timetable for the vaccinations; individuals who are "non-responders" (they do not generate antibodies even after being vaccinated correctly); or other factors such as ethnicity, age, or genetic predisposition. When a vaccinated individual does develop the disease vaccinated against, the disease is likely to be milder than without vaccination.

A common allergy concern for both the influenza virus vaccine and for various measles vaccinations is that they are produced in chicken embryos and therefore they may contain some egg proteins. If a patient has an egg allergy, it may be advisable to avoid the influenza vaccine and should use caution with various vaccines for measles.

-Opioid analgesics are often used to treat acute pain (such as post-operative pain), and for palliative care to alleviate the severe chronic, disabling pain of terminal conditions such as cancer, and sometimes for degenerative conditions such as rheumatoid arthritis. There has been an increased use of opioids in the management of non-malignant chronic pain. Opioids also have antitussive and antidiarrheal effects; therefore, low doses and or weaker forms of these medications will sometimes be used for those purposes as well. These medications do have a potential for abuse due to their addictive nature. While addictive themselves, two of these medications (buprenorphine & naloxone and methadone) can be used to treat opioid addiction. Most of these medications are considered controlled substances and their federal schedules are listed beside them.
