摘要: 目的: 建立一种简便、灵敏的测定人体血浆中吲哒帕胺浓度的高效液相色谱-串联质谱 (HPLC-MS/MS) 方法。方法: 以瑞格列奈钙为内标,采用乙腈:0.1%甲酸水溶液=90∶10为流动相,以Agilent-ZORBAX-C18柱(2.1 mm×150 mm,5.0 m)色谱柱为分析柱,通过电喷雾离子源(ESI),以正离子多反应监测(MRM)方式进行进样检测。检测离子为 [M+H]+m/z 364.1 m/z 188.8(吲哒帕胺)和[M+H]+m/z 451.1 m/z 134.8(瑞格列奈钙,内标)。结果: 吲哒帕胺线性范围为 0.5~50 ng/mL,定量下限为 0.5 ng/mL,线性关系良好;高、中、低三个浓度的日内、日间的RSD均<15%,平均回收率为 94.60%~110.33%。结论: 本方法专属性强,操作简便,灵敏度高,适用于吲哒帕胺制剂的临床药动学研究。

Abstract: AIM: To establish a simple, sensitive method of high performance liquid chromatography tandem mass spectrometry (HPLC-MS/MS) for the determination of Indapamide in human plasma.METHODS: Repaglinide calcium was used as internal standard.Indapamide was separated on an Agilent-ZORBAX-C18 column (2.1 mm×150 mm,5.0 μm).The mobile phase consisted of acetonitrile-0.1% formic acid(90∶10).Electrospray ionization(ES1) was applied and operated in the positive multiple reaction monitoring(MRM) mode,used the transitions of [M+H]+m/z 388.4 m/z 247.4 and [M+H]+m/z 384.2 m/z 231.3 to quantify Indapamide and the internal standard respectively.RESULTS: The linear calibration curve was obtained over the concentration range of 0.5-50 ng/mL.The limit of quantification was 0.5 ng/mL.The inter- and intra-day precision (RSD) were less than 15%.The average recovery was between 94.60% and 110.33%.CONCLUSION: The method had been proved to be specific,convenient,sensitive and suitable for the clinical investigation of Indapamide pharmacokinetics.
