摘要: 目的 建立同时测定血浆中格列美脲及其活性代谢物羟基格列美脲(M1) 的HPLC-MS/MS 分析方法, 研究其在健康人体的药代动力学和安全性。方法 22 名健康男性受试者单剂量口服格列美脲片2 mg, 按规定时间点取血并测定血浆中的格列美脲及代谢物M1 的浓度, 采用WinNonlin 软件计算药代动力学参数。结果 格列美脲和代谢物M1 的Tmax 分别为2.7 ±0.6 和4.2 ±1.6 h, Cmax 分别为188 ±52和34 ±11 μg·L-1 , AUC0 -24 分别为813 ±277 和258 ±66 μg·h·L-1, t 1 2 分别为6.6 ±2.1 和6.3 ±2.5 h 。结论 本文所建立的HPLC-MS/MS 同时测定格列美脲及其代谢物M1 的方法灵敏、准确、可靠, 格列美脲耐受性较好, 在国人与白种人体内的药代动力学特征存在种族差异。

Abstract: AIM: To establish an HPLC-MS MS method for the simultaneous determination of glimepiride and its hydroxy-metabolite M1 in human plasma, and to study their pharmacokinetic profiles in healthy Chinese volunteers.METHODS: A single oral dose of 2 mg glimepiride tablet was given to 22 healthy male volunteers individually.The concentrations of glimepiride and M1 in plasma were determined and their pharmacokinetic parameters were simulated by WinNonlin software.RESULTS: The main pharmacokinetic parameters of glimepiride and M1 were as follows:Tmax 2.7 ±0.6 and 4.2 ±1.6 h,Cmax 188 ±52 and 34 ±11 μg·L-1 , AUC0 -24 813 ±277and 258 ±66 μg·h·L-1 , t1/2 6.6 ±2.1 and 6.3 ±2.5h.CONCLUSION: The HPLC-MS/MS method developed in our lab was sensitive and precise.Glimepiride was well tolerated and exhibited ethnic difference between Chinese and Caucasian.
