Mechanism of action of Felodipine
Felodipine (fe loe' di peen) belongs to the dihydropyridine group of calcium channel blockers (with amlodipine, isradipine and nifedipine) and is used primarily in the therapy of hypertension. Like other calcium channel blockers, felodipine acts by blocking the influx of calcium ions into vascular smooth muscle and cardiac muscle cells during depolarization, which results in arterial vasodilation and decrease in cardiac work and oxygen consumption.
