代谢
氟康唑在肝脏中的代谢非常少。氟康唑是CYP2C9、CYP3A4和CYP2C19的抑制剂。在一项研究中,健康志愿者服用50毫克放射性标记剂量的氟康唑后,尿液中检测到两种代谢物;一种是羟基上的葡萄糖苷酸代谢物(6.5%),另一种是氟康唑N-氧化物代谢物(2%)。同一项研究还表明,没有观察到氟康唑代谢断裂的迹象,这表明与同一药物类别中其他在肝脏中大量代谢的药物相比,其代谢方式有所不同。
Fluconazole is metabolized minimally in the liver. Fluconazole is an inhibitor of CYP2C9, CYP3A4 and CYP2C19. Two metabolites were detected in the urine of healthy volunteers taking a 50 mg radiolabeled dose of fluconazole; a glucuronidated metabolite on the hydroxyl moiety (6.5%) and a fluconazole N-oxide metabolite (2%). The same study indicated that no signs of metabolic cleavage of fluconazole were observed, suggesting a difference in metabolism when compared to other agents in the same drug class, which are heavily metabolized in the liver.
