代谢
在体外,罗沙度坦是CYP2C8和UGT1A9酶的底物。罗沙度坦主要代谢为羟基罗沙度坦和罗沙度坦O-葡萄糖苷酸。在人类血浆中,未改变的罗沙度坦是主要的循环组分,而人类血浆中可检测到的代谢物占总药物相关物质暴露的不到10%。没有观察到人类特异性代谢物,但在人类尿液中检测到了罗沙度坦O-葡萄糖苷酸。
_In vitro_, roxadustat is a substrate for CYP2C8 and UGT1A9 enzymes. Roxadustat is primarily metabolized to hydroxy-roxadustat and roxadustat O-glucuronide. Unchanged roxadustat was the major circulating component in human plasma and detectable metabolites in human plasma constituted less than 10% of total drug-related material exposure. No human-specific metabolites were observed but roxadustat O-glucuronide was detected in human urine sample.
