    Get PDF
    目的探讨他克莫司(TAC)和伏立康唑(VRC)相互作用的机制,为临床合理用药提供依据。方法观察分析1例服用TAC的肾移植术后随访患者,在应用VRC治疗肺部真菌感染前后,TAC体内药物浓度的变化。结果联合用药前,TAC平均谷浓度C0为4.95ng·m L-1(4.3~6.0 ng·m L-1),平均C0/D为2.475 ng/(mg·m L)(2.15~3.0 ng/(mg·m L)),合用VRC后,C0为27.0ng·m L-1,C0/D为13.5 ng/(mg·m L),比未用VRC之前C0/D升高了445.5%。结论长期服用TAC的肾移植术后患者在应用VRC治疗肺部真菌感染时,应综合考虑患者遗传因素(CYP2C19和CYP3A5基因多态等)和非遗传因素,个体化给药。二者相互作用的机制是:VRC抑制肝脏CYP3A4/CYP3A5酶,使TAC的药物浓度显著升高;CYP2C19和CYP3A5基因多态在TAC与VRC相互作用中起了重要作用
