代谢
Epoprostenol 在动物测试系统中被代谢为两种主要代谢物:6-酮基-PGF1α(通过自发降解形成)和6,15-二酮-13,14-二氢-PGF1α(通过酶促形成),这两种代谢物的药理活性均远低于Epoprostenol。从尿液中还分离出了另外十四种次要代谢物,表明Epoprostenol在人体内被广泛代谢。
Epoprostenol is metabolized to 2 primary metabolites: 6-keto-PGF1α (formed by spontaneous degradation) and 6,15-diketo-13,14-dihydro-PGF1α (enzymatically formed), both of which have pharmacological activity orders of magnitude less than epoprostenol in animal test systems. Fourteen additional minor metabolites have been isolated from urine, indicating that epoprostenol is extensively metabolized in humans.
