ADMET

代谢
醋酸赛格司酮在肝脏中迅速代谢和失活。根据体外实验的发现,血清中的主要氧化代谢物包括5α-二氢-和17α-羟基-5α-二氢代谢物,这些代谢物相对于醋酸赛格司酮的暴露量约占50%。这些代谢物在药理学上不活跃,对孕酮受体的EC50(半最大效应浓度)比母体化合物高10倍。研究表明,3α, 5α-四氢醋酸赛格司酮在大脑中的GABA-A受体上作为激活剂。
Segesterone acetate undergoes rapid metabolism and inactivation in the liver. Based on the findings _in vitro_, the major oxidative metabolites in the serum include 5α-dihydro- and 17α-hydroxy-5α­-dihydro metabolites constitute about 50% of exposure relative to segesterone acetate. The metabolites are not pharmacologically active with EC50 to progesterone receptor 10-fold higher than that of the parent compound. It was shown that 3α, 5α-tetrahydrosegesterone acetate acts as an activator at the GABA-A receptors in the brain.

避孕阴道环在为期90天的药代动力学研究中为健康女性提供了超过90天的醋酸诺孕酯避孕水平的持续释放。在使用最多13个周期后,醋酸诺孕酯被吸收进入系统循环,在第1周期、第3周期和第13周期,2小时内达到血浆峰浓度。浓度在达到血浆浓度的时间(Tmax)后下降,并在给药后96小时变得更为稳定。在使用后续周期中,醋酸诺孕酯的血清峰浓度降低。在第1周期、第3周期和第13周期,血浆峰浓度分别为1147、363和294 pg/mL。
Contraceptive vaginal rings provided sustained release of contraceptive levels of segesterone acetate over 90 days in a pharmacokinetic study of healthy women. Following vaginal administration for up to 13 cycles, segesterone acetate was absorbed into systemic administration and reached the peak plasma concentration in 2 hours in Cycle 1, Cycle 3, and Cycle 13. Concentrations declined after time to reach plasma concentration (Tmax) and became more constant after 96 hours post-dose.Over subsequent cycles of use, the peak serum concentrations of segesterone acetate decreased. In Cycle 1, 3 and 13, the peak plasma concentrations were 1147, 363, and 294 pg/mL.
