摘要: 目的: 建立一种快速、灵敏的高效液相色谱-串联质谱法(LC-MS/MS)测定人血浆缬沙坦浓度。方法: 200 μL 血浆样品经乙腈一步沉淀蛋白后,在Inertsil ODS-色谱柱(2.1 mm×150 mm,5 μm)上分离,流动相由乙腈和1‰甲酸水溶液(70∶30)组成。采用电喷雾离子源(ESI源)正离子多反应监测(MRM)扫描分析,缬沙坦和厄贝沙坦的离子选择通道分别为:m/z436.3→235.2 和 429.4→207.2。结果: 缬沙坦的线性范围为 24.2~3100.0 μg/L,日内和日间相对标准差均小于15%。结论: 本法操作快速、灵敏,适用于缬沙坦的临床药动学研究。

Abstract: AIM: To establish a rapid and sensitive LC-MS/MS method for determination of valsartan in human plasma.METHODS: The prepared analytes were separated on an ODS column using mobile phase of acetonitrile and 1‰ methanoic acid (70∶30). Valsartan and irbesartan were detected by multiple reaction monitoring (MRM) mode after ionized by ESI source. The transitions of m/z436.3→235.2 and m/z 429.4→207.2 were used to quantify valsartan and irbesartan, respectively.RESULTS: The method was linear in the range of 24.2-3100.0 μg/L for valsartan. The intra-day mean precision and inter-day mean accuracy precision was not more than 15%.CONCLUSION: The method is rapid and sensitive, and it's adaptive for clinic pharmacokinetic evaluation of valsartan.
