前列腺素是存在于动物和人体中的一类不饱和脂肪酸组成的、具有多种生理作用的活性物质。前列地尔是一种疗效确切的血管扩张药,是一种人体生理物质,有抑制血小板聚集、血栓素A2生成、动脉粥样脂质斑块形成及免疫复合物的作用,并能扩张外周和冠脉血管。PGE2可使支气管平滑肌舒张,降低肺通气阻力,由血管内膜产生的PGI2能抑制血小板聚集,改善微循环。
Prostaglandins are a class of unsaturated fatty acids present in animals and humans, with a variety of physiological effects of active substances. Alprostadil is a potent vasodilator, a human physiologic substance that inhibits platelet aggregation, thromboxane A2 production, atherosclerotic plaque formation, and immune complexes, as well as expanding peripheral and / Coronary artery. PGE2 can make bronchial smooth muscle relaxation, reduce pulmonary ventilation resistance, PGI2 produced by the intima can inhibit platelet aggregation, improve microcirculation.
