Nicardipine is similar to other peripheral vasodilators. Nicardipine inhibits the influx of extra cellular calcium across the myocardial and vascular smooth muscle cell membranes possibly by deforming the channel, inhibiting ion-control gating mechanisms, and/or interfering with the release of calcium from the sarcoplasmic reticulum. The decrease in intracellular calcium inhibits the contractile processes of the myocardial smooth muscle cells, causing dilation of the coronary and systemic arteries, increased oxygen delivery to the myocardial tissue, decreased total peripheral resistance, decreased systemic blood pressure, and decreased afterload.

Drug Category Antiarrhythmic Agents; Vasodilator Agents; Antihypertensive Agents; Dihydropyridines; ATC:C08CA04 Brand Names/Synonyms Cardene; Cardene Sr; Nicardipine; Nicardipine Hcl; Nicardipino [Inn-Spanish]; Nicardipinum [Inn-Latin]; YC-93 Dosage Forms CAPSULE Absorption While nicardipine is completely absorbed, it is subject to saturable first pass metabolism and the systemic bioavailability is about 35% following a 30 mg oral dose at steady state. Interactions -->Interactions for Nicardipine: Beta-Blockers In controlled clinical studies, adrenergic beta-receptor blockers have been frequently administered concomitantly with nicardipine HCl. The combination is well tolerated. Cimetidine Cimetidine increases nicardipine HCl plasma levels. Patients receiving the two drugs concomitantly should be carefully monitored. Digoxin Some calcium blockers may increase the concentration of digitalis preparations in the blood. Nicardipine HCl usually does not alter the plasma levels of digoxin, however, serum digoxin levels should be evaluated after concomitant therapy with nicardipine HCl is initiated. Maalox®* Coadministration of Maalox TC had no effect on nicardipine HCl absorption. Fentanyl Anesthesia Severe hypotension has been reported during fentanyl anesthesia with concomitant use of a beta-blocker and a calcium channel blocker. Even though such interactions were not seen during clinical studies with nicardipine HCl, an increased volume of circulating fluids might be required if such an interaction were to occur. Cyclosporine Concomitant administration of nicardipine and cyclosporine levels. Plasma concentrations of cyclosporine should therefore be closely monitored, and its dosage reduced accordingly, in patients treated with nicardipine. When therapeutic concentrations of furosemide, propranolol, dipyridamole, warfarin, quinidine, or naproxen were added to human plasma (in vitro), the plasma protein binding of nicardipine HCl was not altered.
