前列地尔Alprostadil Prostaglandin E1 (PGE1),known pharmaceutically as alprostadil,is a prostaglandin.It is a drug used in the treatment of erectile dysfunction[2]and has vasodilatory properties. 依前列醇Epoprostenol Prostacyclin(or PGI2),as a drug,is known as 'epoprostenol".The terms are sometimes used interchangeably. Prostacyclin(PGI2)chiefly prevents formation of the platelet plug involved in primary hemostasis (a part of blood clot formation).It does this by inhibiting platelet activation.It is also an effective vasodilator.Prostacyclin's interactions in contrast to thromboxane(TXA2),another eicosanoid,strongly suggest a mechanism of cardiovascular homeostasis between the two hormones in relation to vascular damage.前列地尔 Alprostadil Prostaglandin E1 (PGE1), known pharmaceutically as alprostadil, is a prostaglandin.
