Profiling Antihypertensive Therapy.
The objectives of treating hypertension are to achieve adequate control of blood pressure (BP) and maintain it under tight control. Maintenance of tight control of BP will most likely prevent stroke, heart attack, and heart failure, cause regression of left ventricular hypertrophy, and quite possibly preserve or improve renal function. The last two salutary effects combined will further reduce the morbidity and mortality in the treated hypertensive subjects. Choice of antihypertensive drugs is of significant importance so that our efforts to control hypertension do not grossly alter the quality of life. The cost of therapy is also an important consideration. Thus, thiazide diuretics, beta-blockers, and central inhibitors that are relatively inexpensive and adequately lower BP should be a common choice. However, if drowsiness interferes with work, or impotence becomes a threat for the marital partner or significant other, adjustment has to be made. The metabolic abnormalities consisting mainly of impaired glucose tolerance, hypercholesterolemia, and insulin resistance often induced by these relatively inexpensive drugs have put calcium channel blocker and ACE inhibitor group of drugs on the top of the list for antihypertensive therapy. They are far more expensive, yet offer no greater antihypertensive advantage than a diuretic or central inhibitor, except in special circumstances.
