代谢
糖苷酸化是主要的代谢途径。口服给药后,巴泽多昔芬通过UDP-葡萄糖苷酸转移酶(UGTs)代谢为巴泽多昔芬-4'-葡萄糖苷酸(M4)和巴泽多昔芬-5-葡萄糖苷酸(M5)。几乎没有明显的细胞色素P450介导的代谢。这种葡萄糖苷酸的浓度大约是未改变的活性物质在血浆中浓度的10倍。
Glucuronidation is the major metabolic pathway. After peroral application, bazedoxifene is metabolized by UDP-glucuronosyltransferases (UGTs) to bazedoxifene-4'-glucuronide (M4) and bazedoxifene-5-glucuronide (M5).Little or no cytochrome P450-mediated metabolism is evident. The concentrations of this glucuronide are approximately 10-fold higher than those of unchanged active substance in plasma.
