Circulatory System Drugs

Nifedipine is a dihydropyridine calcium antagonist, which can inhibit the Ca2 + uptake of myocardium and vascular smooth muscle, dilate coronary artery, increase coronary blood flow, improve myocardial tolerance to ischemia, dilate peripheral small arteries, reduce peripheral vascular resistance, relieve coronary artery spasm, increase coronary blood flow, improve myocardial hypoxia, and reduce blood pressure. Low dose coronary artery dilation does not affect blood pressure, so it is a good anti angina drug. For the prevention and treatment of angina pectoris of coronary heart disease, it has no adverse effect on respiratory function, especially for angina pectoris caused by coronary artery spasm and angina pectoris with respiratory obstructive disease, the effect is the best, and its curative effect is better than that of traditional Chinese medicine β Receptor blockers. It is also suitable for various types of hypertension, including severe and refractory hypertension. It can be used for a long time in the treatment of refractory congestive heart failure. It is also used in the treatment of primary pulmonary hypertension, diffuse esophageal spasm, bronchial asthma, duodenal ulcer, urethral obstruction, exercise-induced asthma, achalasia, etc.

Angiotensin converting enzyme inhibitor can significantly reduce blood pressure and reduce cardiac load. It is also effective for different types of hypertension and heart failure. And diuretic hydrochlorothiazide into a compound, with the trade names of capozide and acezide.

Cardiotonics that enhance cardiac contractility and directly dilate blood vessels

This product is a hypolipidemic drug, used for Hypolipidemia.

Trimetazidine hydrochloride belongs to other anti angina cardiovascular drugs. It protects the energy metabolism of cells under hypoxia or ischemia and prevents the decline of intracellular ATP level, so as to ensure the normal function of ion pump and the normal operation of transmembrane sodium potassium flow, and maintain the stability of intracellular environment.
