title: Usefulness of nicardipine as monotherapy for chronic, stable angina.
abstract: Using a double-blind, Latin square protocol designed to detect dose response, nicardipine hydrochloride, a new calcium antagonist, was studied as monotherapy for stable exertional angina. Eighty-one patients were enrolled in the trial and 62 patients were included in greater than or equal to 1 primary efficacy analyses. Patients received 1 to 2 weeks of placebo run-in, then 5 weeks of treatment with placebo and with 10, 20 and 30 mg of nicardipine given 3 times daily. Patients completed symptom diaries, were monitored with 24-hour electrocardiographic Holter monitors and underwent serial exercise treadmill tests. By 1 hour, 10, 20 and 30 mg of nicardipine administered 3 times daily produced statistically significant, dose-related improvements in all key exercise parameters, which persisted at the 4-hour evaluation. The systolic blood pressure at rest and during exercise decreased, but the pulse slightly increased. The peak rate-pressure product was unchanged. The side effects were not severe. Nicardipine hydrochloride is an effective, well-tolerated medication for the treatment of stable exertional angina, and is a good alternative to currently available calcium antagonists.
