A LC-MS/MS method was established for the determination of pinaverium in human plasma. Paclitaxel was used as the internal standard. A C18 column was used with the mobile phase of acetonitrile-2 mmol/L ammonium acetate-formic acid (70︰30︰0.1) in multiple reaction monitoring (MRM) mode with the transitions of m/z 512.5→231.3(pinaverium) and m/z 854.3→286.3(paclitaxel), respectively. The recoveries of pinaverium at low, medium and high concentration levels were 111.7%, 104.9% and 99.7%, respectively. The inter- and intra-day RSDs were less than 15%.
