  • Objective To establish a method for determining Esomeprazole in dog plasma by LC-MS-MS. Methods Diazepam was used as the internal standard,the samples were precipitated with acetonitril. Analytical column was Shim-pack XR-ODS (2 mm×100 mm, 5 μm). The mobile phase was acetonitrile:2 mmol/L ammonium acetate (containing 0.1% formic acid) at a flow rate of 0.3 ml/min. Mass spectrum conditions was ESI performing in positive ion MRM mode using target ions 346.2→198.2 m/z (esomeprazole)and 285.2→193.2 m/z (diazepam). Results The calibration curve was linear over the range of 0.5~1 200 μg/L. The LLOQ of Esomeprazole in plasma was 0.5 μg/L. The average extracted recovery was (101.0±6.5)%. The RSDs of intra- and inter-day were less than 15%. Conclusion The method was sensitive, simple and accurate to determinate Esomeprazole plasma concentration and suitable to the pharmacokinetics study.
