title: Nicardipine in elderly patients with hypertension: a review of experience in France.
abstract: A double-blind, placebo-controlled clinical trial in France has studied the efficacy and safety of nicardipine in 31 elderly patients, aged 57 to 95 years (mean age 84 years), 16 of whom were actively treated with nicardipine, 10 to 30 mg three times a day (mean dose 69.4 mg/day). After 4 weeks, nicardipine lowered mean blood pressure (186/99 to 150/83 mm Hg; p less than 0.001), and the changes in systolic and diastolic blood pressure were significantly greater in the nicardipine group than in the placebo group. Nicardipine was well tolerated; orthostatic hypotension was not observed and there was no change in heart rate. Plasma renin activity (PRA) was measured in eight patients, but there was no correlation between PRA and the antihypertensive effect of nicardipine. Results of a pharmacokinetic study performed in 15 elderly patients showed a rapid rate of absorption and higher plasma levels than those observed in younger patients with hypertension (mean age 54 years). The results support those of the major French multicenter open study of 29, 104 elderly patients with hypertension (mean age 64 +/- 12 years) treated with nicardipine. The findings of this trial are reviewed and discussed, and recommendations made on the directions for future research in cardiovascular medicine with calcium channel blockers. Results of the trials discussed in this article show that nicardipine is an effective and well-tolerated drug in elderly patients and has wide-ranging effects on the cardiovascular system.
