GENERIC NAME: nisoldipine


DRUG CLASS AND MECHANISM: Nisoldipine is an oral calcium channel blocker (CCB) of the dihydropyridine (DHP) class that is used to treat high blood pressure. Other calcium channel blockers in the DHP class include nifedipine (Procardia, Adalat), amlodipine (Norvasc), felodipine (Plendil), nicardipine (Cardene), and isradipine (Dynacirc). Calcium channel blockers prevent calcium from entering certain types of muscle cells. Since the muscle cells need calcium to contract, CCBs prevent the cells from contracting, that is, they cause the muscle cells to relax. Nisoldipine selectively relaxes the muscles of small arteries causing the arteries to dilate but has little or no effect on muscles of veins or the heart. Dilation of arteries reduces blood pressure. Nisoldipine was approved by the FDA in February of 1995.
