Levamlodipine Besylate Tablets

1. This product is a calcium influx blocker (also known as a calcium channel blocker or calcium ion antagonist), which blocks the extracellular calcium ions of myocardial and vascular smooth muscle cells from entering cells through the calcium ion channels (slow channels) of the cell membrane. 2. This product directly relaxes vascular smooth muscle and has an antihypertensive effect. 3. The mechanism of action of this product in relieving angina pectoris has not been fully determined, but it reduces myocardial ischemia through the following effects: 4. Dilates peripheral arterioles, reduces peripheral resistance (afterload), and thus reduces myocardial energy consumption and oxygen demand; 5. Dilates coronary arteries and coronary arterioles in normal and ischemic areas, increasing myocardial oxygen supply in patients with coronary artery spasm (variant angina pectoris). 6. This product takes a long time to metabolize in the liver. Like all other calcium antagonists, it should be used with great caution when liver function is impaired.
