A comparative study of the effects of nitrendipine and enalapril in essential hypertension.

In this study, we compared the effects of nitrendipine (20-40 mg daily) and enalapril (20-40 mg daily) in 44 patients with mild to moderate essential hypertension. After a 4-week placebo period, the patients entered a doubleblind, crossover study of 16 weeks, divided by a second 4-week placebo period. Sitting and standing blood pressures (standard mercurymeter) were measured every 2 weeks. Ten patients dropped out, so 34 patients were evaluable
