代谢
口服给药后,盐酸头孢克肟悬浮剂迅速被肠道粘膜和血液中的非特异性酯酶水解为头孢克肟;悬浮剂的基团代谢为乙醛和醋酸。头孢克肟不代谢,主要通过肾小球过滤和肾小管分泌,以原型主要在尿液中排泄。
Following oral administration, cefuroxime axetil is rapidly hydrolyzed to cefuroxime by nonspecific esterases in the intestinal mucosa and blood; the axetil moiety is metabolized to acetaldehyde and acetic acid. Cefuroxime is not metabolized and is excreted unchanged principally in urine by both glomerular filtration and tubular secretion.
