Nicardipine hydrochloride (Cardene) is a medication used to treat high blood pressure and angina. It belongs to the dihydropyridine class of calcium channel blockers. Nicardipine is a dihydropyridine calcium-channel blocking agent used for the treatment of vascular disorders such as chronic stable angina, hypertension, and Raynaud's phenomenon. Its mechanism of action and clinical effects closely resemble those of nifedipine and the other dihydropyridines (amlodipine, felodipine), except that nicardipine is more selective for cerebral and coronary blood vessels.
