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.
