Efficacy and safety of nicardipine for chronic, stable angina pectoris: a multicenter randomized trial

The American Journal of Cardiology
S ScheidtD Freedman


Nicardipine, a new calcium channel blocking drug of the dihydropyridine family, was administered to 63 patients at a dose of 30 or 40 mg 3 times daily in a multicenter, randomized, double-blind, placebo-controlled, crossover trial. Nicardipine midly increased heart rate (HR) at rest and midly decreased the blood pressure (BP) at rest. When generally similar responses to the 30- and 40-mg doses were averaged, nicardipine produced a 7% increase in peak exercise HR, which was balanced by a 6% decrease in peak exercise BP. Thus, no change occurred in the exercise HR-BP product. With nicardipine, treadmill exercise duration increased 9%, time to angina increased 15%, time to 1-mm ST-segment depression increased 16%, and oxygen consumption at peak exercise increased 13%. Mean anginal frequency declined, as did mean weekly sublingual nitroglycerin consumption, but not significantly. There were more cardiovascular side effects with nicardipine than with placebo, with at least 3 patients having increased angina judged by investigators as probably related to the drug. Vasodilatory side effects were also more frequent with nicardipine, but were generally mild and well tolerated; the drug had to be discontinued in only 1 patient, because o...Continue Reading

Antianginal Drugs: Mechanisms of Action

Antianginal drugs, including nitrates, beta-blockers, and calcium channel blockers, are used in the treatment of angina pectoris. Here is the latest research on their use and their mechanism of action.

Cardiovascular Diseases: Risk Factors

Cardiovascular disease is a significant health concern. Risk factors include hypertension, obesity, dyslipidemia and smoking. Women who are postmenopausal are at an increased risk of heart disease. Here is the latest research for risk factors of cardiovascular disease.
