代谢
肝脏。 Roxithromycin 只有部分被代谢,超过一半的母体化合物未经改变就被排出。在尿液和粪便中已鉴定出三种代谢物:主要代谢物是去克拉定糖罗西地霉素,少量的N-单脱甲基罗西地霉素和N-双脱甲基罗西地霉素。罗西地霉素及其这三种代谢物在尿液和粪便中的百分比相似。
Hepatic. Roxithromycin is only partially metabolised, more than half the parent compound being excreted unchanged. Three metabolites have been identified in urine and faeces: the major metabolite is descladinose roxithromycin, with N-mono and N-di-demethyl roxithromycin as minor metabolites. The respective percentage of roxithromycin and these three metabolites is similar in urine and faeces.
