代谢
主要经肝脏通过CYP1A2和CYP3A4代谢。主要代谢物是葡萄糖醛酸苷结合物;次要代谢物包括硫酸盐结合物和氧化代谢物。氧化代谢物主要由细胞色素P450酶CYP1A2形成,而细胞色素P450酶CYP3A4的作用较小。与母药相比,非结合代谢物的抗菌活性很小,而结合代谢物则没有抗菌活性。
Primarily hepatic via CYP1A2 and CYP3A4. The major metabolite is a glucuronide conjugate; minor metabolites include sulfate conjugates and oxidative metabolites. The oxidative metabolites are formed mainly by the cytochrome P450 enzyme CYP1A2, while the cytochrome P450 enzyme CYP3A4 plays a minor role. The nonconjugated metabolites have little antimicrobial activity compared with the parent drug, and the conjugated metabolites have no antimicrobial activity
