Acute and short-term effects of nitrendipine and diltiazem at rest and during exercise in hypertensive patients.
The subjects were 30 patients with mild-to-moderate hypertension randomly assigned to receive 10 mg of nitrendipine twice daily or 60 mg of diltiazem thrice daily for 14 days. On days 1 and 14 the patients performed an effort test (to a maximum of 100 W) before and after drug administration. Both nitrendipine and diltiazem reduced systolic and diastolic blood pressure; after 14 days of treatment, the reductions in blood pressure were significantly greater in the nitrendipine-treated patients than in the diltiazem-treated patients. Blood pressures were reduced at maximum effort in both treatment groups before drug administration on day 14 compared with day 1. Two hours after drug administration on days 1 and 14, the reductions in effort blood pressures were significantly greater after nitrendipine than after diltiazem. No side effects were noted in either group. It is concluded that nitrendipine is safe and effective in patients with mild-to-moderate hypertension at rest and during exercise.
