摘要: 目的 探讨泮托拉唑对人肝脏药物代谢酶CYP1A2、NAT2和XO活性的影响,预测泮托拉唑与常用药物的相互作用,指导临床医师合理用药。方法 以咖啡因作为药物代谢酶CYP1A2、NAT2和XO的探针药物,以反相高效液相梯度洗脱法测定30名受试者服用泮托拉唑前后人尿液内咖啡因5种主要代谢产物的相对含量,采用代谢物的比率分别评价人肝脏药物代谢酶CYP1A2、NAT2和XO活性的变化。结果 受试者用药前CYP1A2、NAT2和XO平均活性为3.37±1.22、0.50±0.09、0.49±0.09;服用泮托拉唑7d后CYP1A2、NAT2和XO平均活性为3.50±1.23、0.48±0.12、0.48±0.13;服药前后3种酶活性没有显著性差异(P>0.05)。结论 泮托拉唑对人肝脏药物代谢酶CYP1A2、NAT2和XO活性无明显影响,泮托拉唑可能不会影响与之合用的需经CYP1A2、NAT2和XO代谢的药物临床疗效。

Abstract: AIM: To investigate the effect of pantoprazole on Cytochrome P4501A2 (CYP1A2),N-acetyltransferase2(NAT2),and xanthine oxidase(XO) activity in human and to forecast the drug-drug interaction with it,so as to instruct clinician to prescribe rationally.METHODS: In thirty volunteers,use two-way cross design,caffeine was used as a metabolic probe for CYP1A2 、NAT2,and XO,before and after pantoprazole administration,urine samples were collected.The contents of five major metabolites of caffeine in the urine were determined by RP-HPLC method and then evaluated the activity change of CYP1A2 、NAT2,and XO by the ratio of metabolites of caffeine.RESULTS: It was found that the average activity of CYP1A2 、NAT2,and XO were 3.37±1.22,0.50±0.09,0.49±0.09 with before treatment,and 7 days after treatment,the average activity of CYP1A2 、NAT2,and XO were 3.50±1.23,0.48±0.12,0.48±0.13.There were no statistical significance between before treatment and after treatmen(P>0.05).CONCLUSIONS: Pantoprazole have no influence on CYP1A2 、NAT2,and XO,so pantoprazole do not modify the efficacy of drugs which metabolized by CYP1A2 、NAT2,and XO taken simultaneously.
