INTRODUCTION

++

The following list is a compilation of the drugs that are most likely to appear on examinations. The brief descriptions should serve as a rapid review. The list can be used in 2 ways. First, cover the column of properties and test your ability to recall descriptive information about drugs picked at random from the left column; second, cover the left column and try to name a drug that fits the properties described. The numbers in parentheses at the end of each drug description denote the relevant chapter.

Drug Properties
Abciximab Monoclonal antibody that inhibits the binding of platelet glycoprotein IIb/IIIa (GPIIb/IIIa) to fibrinogen. Used to prevent clotting after coronary angioplasty and in acute coronary syndrome. Eptifibatide and tirofiban are also GPIIb/IIIa inhibitors. (34)
Acetaminophen Antipyretic analgesic: very weak cyclooxygenase inhibitor; not anti-inflammatory. Less GI distress than aspirin but dangerous in overdose. Tox: hepatic necrosis. Antidote: acetylcysteine. (36)
Acetazolamide Carbonic anhydrase-inhibiting diuretic acting in the proximal convoluted tubule: produces a NaHCO3 diuresis, results in bicarbonate depletion and metabolic acidosis. Has self-limited diuretic but persistent bicarbonate-depleting action. Used in glaucoma and mountain sickness. Tox: paresthesias, hepatic encephalopathy. Dorzolamide and brinzolamide are topical analogs for glaucoma. (15)
Acetylcholine Cholinomimetic prototype: transmitter in CNS, ENS, all ANS ganglia, parasympathetic postganglionic synapses, sympathetic postganglionic fibers to sweat glands, and skeletal muscle end plate synapses. (6, 7)
Acyclovir Antiviral: inhibits DNA synthesis in herpes simplex virus (HSV) and varicella-zoster virus (VZV). Requires activation by viral thymidine kinase (TK strains are resistant). Tox: behavioral effects and nephrotoxicity (crystalluria) but minimal myelosuppression. Famciclovir, penciclovir, and valacyclovir are similar but with longer half-lives. (49)
Adenosine Antiarrhythmic: miscellaneous group; parenteral only. Hyperpolarizes AV nodal tissue, blocks conduction for 10–15 s. Used for nodal reentry arrhythmias. Tox: hypotension, flushing, chest pain. (14)
Albuterol Prototypic rapid-acting β2 agonist; important use in acute asthma. Tox: tachycardia, arrhythmias, tremor. Other drugs with similar action: metaproterenol, terbutaline. Slow-acting analogs: formoterol, salmeterol; used for prophylaxis. (9, 20)
Alendronate Bisphosphonate: chronic treatment with low doses increases bone mineral density and reduces fractures. Higher doses lower serum calcium. Used in osteoporosis and for the hypercalcemia in Paget’s disease and malignancies. Tox: esophageal irritation at low oral doses. Renal dysfunction and osteonecrosis of the jaw in high doses. ...
