摘要: 目的: 建立一种简单、有效且灵敏的液质联用法(LC-MS/MS)检测人血浆中吲达帕胺浓度。方法: 血浆样品经叔丁基甲基醚(tert-Butyl Methyl Ether, MTBE)萃取后,选安定作内标。色谱柱为Luna C18柱(150 mm×2.0 mm, 5 μm);流动相为 10 mmol/L 甲酸铵(含0.1%甲酸):甲醇=(20∶80,V/V);流速为 0.30 mL/min;采用ESI+ MRM方式监测;源电压:3.5 kV;源温度:100 ℃;吲达帕胺和安定的离子选择通道分别为:m/z 366.2→132.1,285.2→154.1。结果: 吲达帕胺线性范围为 0.536~45.733 ng/mL,最低检测浓度为 0.536 ng/mL,提取回收率在69%~81%,日内、日间RSD均<15%。由湖南协力药业有限公司生产生产的吲达帕胺缓释片(1.5 mg/片)与施维雅(天津)制药有限公司生产的吲达帕胺缓释片(商品名:纳催离,1.5 mg/片)经单次及多次给药试验研究,具有生物等效性。结论: 本方法简单、灵敏,可准确检测人体血浆中吲达帕胺的浓度。

Abstract: AIM: To establish a simple, effective and sensitive LC-MS/MS assay to determine Indapamide in human plasma. METHODS: Diazepam was used as an internal standard. Human plasma samples were extracted by MTBE(tert-Butyl Methyl Ether).The separation was carried out on a Luna C18 (150 mm×2.0 mm, 5 μm) column.The mobile phase consisted of 10 mmol/L ammonium formate with 0.1% formic acid:methanol (20∶80, V/V) at a flow rate of 0.30 mL/min. Electrospray ionization(ESI) source was applied and operated in the positive ion mode. The MS detection parameters were as follows: the source voltage was 3.5 KV and source temperature was 100 ℃. Quantitation was performed using multiple reaction monitoring(MRM) of the m/z 366.2→132.1 for Indapamide and 285.2→154.1 for diazepam.RESULTS: The liner calibration curves were obtained in the range of 0.536-45.733 ng/mL for Indapamide. The lower limit of quantification was 0.536 ng/mL.The mean relative recovery was 69%~81% and the relative standard deviation of the intra-day and inter-day precision of variation were less than 15%. By single and multiple doses studies, we can demonstrate that Indapamide sustained release tablets (1.5 mg/tablet) produced by Hunan Xieli Pharmaceutical Co.,Ltd and Servier(Tianjin) Pharmaceutical Co.,Ltd are bioequivalent. CONCLUSION: This method which is simple and sensitive can be used to determinate the concentration of Indapamide in human plasma.
