title: Comparison of benazepril and other antihypertensive agents alone and in combination with the diuretic hydrochlorothiazide.
abstract: The safety and efficacy of benazepril, as monotherapy or as part of combination therapy with the diuretic hydrochlorothiazide, have been assessed in a number of studies, including comparative trials with the antihypertensive agents propranolol and nifedipine. These studies have included over 1300 patients with mild-to-moderate hypertension. Comparisons of the efficacy of benazepril and hydrochlorothiazide alone and in combination have shown that benazepril 20 mg once daily is as effective as or more effective in lowering diastolic blood pressure than hydrochlorothiazide 25 mg once daily and that the combination of benazepril 20 mg and hydrochlorothiazide 25 mg has a possibly synergistic effect on diastolic blood pressure. The results of comparative trials of benazepril with propranolol and nifedipine suggest that benazepril, administered alone or with the diuretic hydrochlorothiazide, is as effective as the other antihypertensive agents alone or in combination with hydrochlorothiazide. An additional study demonstrated that the combination of benazepril and nifedipine further lowered diastolic blood pressure in patients not responding to monotherapy with these agents. The safety of monotherapy with benazepril was found to be similar to that of the other antihypertensive agents. Safety of the combination of benazepril and hydrochlorothiazide was shown to be better than that of the combination of propranolol and hydrochlorothiazide. An attenuation of adverse experiences observed during nifedipine monotherapy was obtained when benazepril was added to the nifedipine regimen.
