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 relevant chapter.

|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.|
|Acetaminophen||Antipyretic analgesic: very weak cyclooxygenase inhibitor; not anti-inflammatory. Less GI distress than aspirin but dangerous in overdose. Tox: hepatic necrosis. Antidote:acetylcysteine.|
Carbonic anhydrase-inhibiting diuretic acting in the proximal convoluted tubule: produces a NaHCO3diuresis, 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.
|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. |
|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. |
|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. |
|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. |
|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. Other bisphosphonates include etidronate, pamidronate, risedronate, etc. |
|Allopurinol||Irreversible inhibitor of xanthine oxidase; reduces production of uric acid. Used in ...|
