Cloxodipine maleate dispersible tablets are mainly used to inhibit the inward flow of cell membrane calcium channels, which produces the effects of lowering blood pressure and anti-angina. 1. Lowering blood pressure: Chlordiazepoxide is a calcium antagonist, which can block the extracellular calcium ions of myocardial and vascular smooth muscle, and enter into the cell through the cell membrane calcium channel, which can directly relax the vascular smooth muscle, make the blood vessel dilate and lower the blood pressure. 2. Anti-angina: it can selectively dilate peripheral small arteries and coronary arteries, reduce the resistance of peripheral blood vessels, reduce the afterload of the heart, reduce the heart’s energy consumption and the demand for oxygen; dilate the coronary arteries, increase the coronary artery blood flow, and improve the blood supply to the myocardium, so as to alleviate angina pectoris. Taking amlodipine maleate tablets may have side effects such as headache, edema, fatigue, drowsiness, flushing, palpitations and gastrointestinal reactions, and it is recommended to take the medication reasonably under the guidance of a doctor.
