The efficacy and safety of various doses of losartan potassium, a specific and selective angiotensin II receptor antagonist, were compared with those of placebo and enalapril maleate 20 mg in patients with mild to moderate essential hypertension in a randomized, double-blind, parallel study. We randomly allocated 576 patients at the end of a 4-week placebo baseline period to 8 weeks of once-daily double-blind treatment with losartan potassium 10, 25, 50, 100, or 150 mg, enalapril maleate 20 mg, or placebo. After 8 weeks of treatment, mean reductions from baseline in supine systolic/diastolic pressure 24 hours after dosing (trough) for losartan potassium 10, 25, 50, 100, and 150 mg, enalapril maleate 20 mg, and placebo were 7.6/7.9, 7.8/6.8, 13.0/10.1, 8.9/9.9, 10.5/9.7, 14.7/11.2, and 3.8/5.6 mm Hg, respectively. Compared with mean changes in supine diastolic pressure in the placebo group, losartan potassium 50 to 150 mg and enalapril maleate 20 mg produced clinically important and statistically significant reductions (P < or = .01) in blood pressure. At 24 hours after dosing, the blood pressure changes obtained with losartan potassium 50 mg were essentially identical to those obtained with enalapril maleate 20 mg. While there was a dose-related effect with losartan potassium from 10 to 50 mg at peak (6 hours after dosing), doses of 10 and 25 mg were not consistently different from placebo 24 hours after dosing. To assess the once-daily effect of losartan potassium, trough-to-peak ratios of the mean changes in supine diastolic pressure after 8 weeks of treatment were calculated.(ABSTRACT TRUNCATED AT 250 WORDS)
