英文摘要The study aims to develop a rapid, sensitive and specified method of liquid chromatography with heated electrospray ionization tandem mass spectrometry (LC-HESI/MS/MS) for simultaneous determination of amlodipine, benazepril and benazeprilat in human plasma using amlodipine-d4 and ubenimex as internal standards (ISs). Selected reaction monitoring (SRM) with heated electrospray ionization (HESI) was used in the positive mode for mass spectrometric detection. Analytes and ISs were extracted from plasma by simple protein precipitation. The reconstituted samples were chromatographed on a C_(18) (100 mm * 4.6 mm, 5 mum) column with mixture of methanol-acetonitrile-5 mmol?L~(-1) ammonium acetate-formic acid (30∶30∶40∶0.1) as mobile phase at a flow rate of 0.6 mL?min~(-1). The standard curves were demonstrated to be linear in the range of 0.02 to 6.00 ng?mL~(-1) for amlodipine, 0.2 to 1 500 ng?mL~(-1) for benazepril and benazeprilat with r~2 > 0.99 for each analyte. The lower limit of quantitation was identifiable and reproducible at 0.02, 0.2 and 0.2 ng?mL~(-1) for amlodipine, benazepril and benazeprilat, respectively. The intra-day and inter-day precision and accuracy results were within the acceptable limit across all concentrations. The plasma samples were stable after four freeze-thaw cycles and being stored for 93 days at -20 ℃. The method was applied to a pharmacokinetic study of a fixed-dose combination of amlodipine and benazepril on Chinese healthy volunteers.
