Comparative efficacy of nicardipine, a new calcium antagonist, versus nifedipine in stable effort angina

The relative efficacy of nicardipine and nifedipine was examined in a double-blind placebo-controlled randomized crossover trial. We studied 12 patients with chronic effort angina involving reproducible angina and greater than or equal to 1.5 mm of ST-segment depression on exercise treadmill test performed before and after a 1-week control period of single-blind placebo administration. Subsequently, indistinguishably prepared nicardipine 20 mg, nifedipine 10 mg, or placebo, four times a day, was administered in a randomized double-blind crossover fashion for 3 weeks (total study period 9 weeks). Exercise treadmill test was performed at the end of each 3-week period. Both nicardipine and nifedipine significantly reduced the frequency of anginal attacks and nitroglycerin consumption. Compared with placebo both drugs caused a comparable increase of the duration of exercise, of the time to angina and to the appearance of 1.5 mm ST-segment depression (P less than 0.05 placebo versus nicardipine; P less than 0.01 placebo versus nifedipine respectively). No significant side effects were observed with either drug. We conclude that nicardipine and nifedipine produce similar hemodynamic and clinical effects in patients with stable effort...Continue Reading
