Calcium ion blockers block calcium ions from entering myocardial and vascular smooth muscle cells across the membrane, directly relax vascular smooth muscle, reduce cardiac afterload, reduce cardiac energy consumption and oxygen demand, and thus relieve angina pectoris. They dilate peripheral arterioles and coronary arteries, reduce total peripheral vascular resistance, and relieve coronary artery spasm.

Amlodipine is a calcium ion blocker (also known as calcium channel inhibitor or calcium ion antagonist), which blocks calcium ions from entering myocardial and vascular smooth muscle cells across the membrane. The mechanism of amlodipine's antihypertensive effect is to directly relax vascular smooth muscle. The exact mechanism of relieving angina pectoris has not been fully confirmed, but it can dilate peripheral arterioles and coronary arteries, reduce total peripheral vascular resistance, relieve coronary artery spasm, reduce the afterload of the heart, reduce cardiac energy consumption and oxygen demand, thereby relieving angina pectoris.
