nicardipine

Nicardipine (Cardene) is a medication used to treat angina and hypertension, especially for hemorrhagic stroke patients. It belongs to the dihydropyridine class of calcium channel blockers (CCBs). It is also used for Raynaud's phenomenon. It is available in by mouth and intravenous formulations. It has been used in percutaneous coronary intervention.

Its mechanism of action and clinical effects closely resemble those of nifedipine and the other dihydropyridine calcium channel blockers (amlodipine, felodipine), except that nicardipine is more selective for cerebral and coronary blood vessels. It is primarily a peripheral arterial vasodilator, thus unlike the nitrovasodilators (nitroglycerin and nitroprusside), cardiac preload is minimally affected. It has the longest duration among parenteral CCBs. As its use may lead to reflex tachycardia, it is advisable to use it in conjunction with a beta-blocker. In the setting of a ruptured brain aneurysm, nicardipine may be used (if nimodipine is unavailable) to reduce blood pressure and as prevention or treatment against cerebral vasospasm.
