Amlodipine (as besylate, mesylate or maleate) is a long-acting calcium channel blocker (dihydropyridine) used as an anti-hypertensive and in the treatment of angina. As other calcium channel blockers, amlodipine acts by relaxing the smooth muscle in the arterial wall, decreasing peripheral resistance and hence reducing blood pressure; in angina it increases blood flow to the heart muscle.
