title: Drug therapy for hypertension in the elderly.
abstract: Essential hypertension is a major health care problem in the elderly and requires effective treatment to reduce morbidity and mortality. The traditional stepped-care approach to therapy consisted of diuretics; sympatholytic agents, or beta-blockers for all age groups. Indeed, initial therapy with these agents is effective in 50 to 60 percent of elderly patients but may produce adverse effects. A high incidence of adverse responses, including sexual dysfunction and central nervous system impairment, has been reported with diuretic or beta-blocker therapy, and a reduction in several measures of quality of life has been noted during therapy with methyldopa or propranolol. Administration of an angiotensin-converting enzyme (ACE) inhibitor is as effective as the traditional stepped-care approach without producing the ill effects associated with diuretics, sympatholytics, or beta-blockers. The combination of an ACE inhibitor with a diuretic produces additive antihypertensive effects while minimizing diuretic-induced metabolic alterations. Orthostatic hypotension with the first dose can be minimized by making sure that patients are not hypovolemic from previous diuretic therapy. Nevertheless, in controlled trials, the combination of ACE inhibitor and diuretic has been effective in up to 85 percent of patients. In addition, the use of ACE inhibitors may be beneficial in the hypertensive patient with concomitant congestive heart failure. Most important, the patient's quality of life is maintained during therapy with an ACE inhibitor alone or in combination with a diuretic. Thus, an ACE inhibitor plus a diuretic is a valuable alternative to traditional antihypertensive therapy in elderly patients.
