Comparison of nicardipine and propranolol for chronic stable angina pectoris.

Abstract

In a double-blind, randomized, crossover clinical trial, a new calcium antagonist, nicardipine (90 mg/day in 3 divided doses), was compared with propranolol (120 mg/day in 3 divided doses) in 25 patients with chronic stable angina. The mean weekly frequency of angina episodes decreased from 7.8 +/- 1.2 (+/- standard error of the mean) with placebo to 3.8 +/- 1.2 with nicardipine treatment and 3.5 +/- 1 with propranolol treatment (p less than 0.001). With exercise testing, 5 patients receiving nicardipine and 3 receiving propranolol had no angina or ST-segment changes. Comparing paired samples of both drugs with placebo, significant improvement occurred in exercise duration (nicardipine, 1.3 +/- 0.3 minutes, p less than 0.001; propranolol, 1.0 +/- 0.4 minutes, p less than 0.01), time to onset of angina (nicardipine, 1.5 +/- 0.4 minutes, p less than 0.001; propranolol, 1.5 +/- 0.5 minutes, p less than 0.001), maximal ST-segment changes (nicardipine, 0.7 +/- 0.1 mm, p less than 0.01; propranolol, 0.06 +/- 0.1 mm, p less than 0.01) and time to 1 mm of ST depression (nicardipine, 2.5 +/- 0.4 minutes, p less than 0.01; propranolol, 2.0 +/- 0.3 minutes, p less than 0.01). One patient receiving propranolol and 2 receiving nicardipine withdrew from the study because of transient side effects. Mild side effects occurred in 10 patients receiving propranolol and 5 receiving nicardipine. Nicardipine proved to be safe and effective for patients with chronic stable angina; it had fewer side effects than propranolol in the doses used.
