Introduction
Alprostadil, also named Prostaglandin E1 or PEG1. It is widely present in the body of biologically active substances, as one of the prostaglandin family, it is a recognized endogenous physiologically active substance.
It can be used directly on vascular smooth muscle, to dilates blood vessels and increases blood flow, which can improve microcirculation perfusion. It can inhibit platelet aggregation and thromboxane A2 production, as well as inhibits atherosclerosis, lipid plaque and immune complex formation.
It also owns following effects: to expansion of the periphery small blood vessels and coronary arteries, reduction of peripheral vascular resistance and blood pressure. To protect platelet membrane which can against thrombosis. To protection the ischemic myocardium, which can reducing myocardial infarct size. It use to treat anti-heart failure as well. It has diuretic and renal-protecting function, base on expansion renal blood vessels in order to increase renal blood flow. During this way, it can remove non-protein nitrogen, and regulating sodium and water balance.
It’s clinically usage are widely. Such as for diabetic complications, coronary heart disease and intractable heart failure. Also usage on situation like congenital heart disease complicated with pulmonary hypertension, cerebral infarction and chronic arterial occlusive disease. For some cases like sudden deafness, retinal vein occlusion, viral hepatitis or chronic gastritis, it also have function.
