By matching the profile of an antihypertensive drug to the clinical an
d demographic characteristics of the patient (e.g., risk factors, coex
isting diseases, goals of therapy beyond lowering blood pressure), the
physician can maximize the efficacy of the regimen and minimize the a
dverse effects the patient may experience. Optimal therapy requires a
knowledge of the pharmacologic properties of the six broad classes of
antihypertensive drugs: diuretics, sympatholytics (including central a
nd peripheral adrenergic receptor blockers), direct vasodilators, angi
otensin-converting enzyme inhibitors, calcium channel blockers and ang
iotensin II receptor antagonists.
