英文摘要 | Objective: To develop and validate a liquid chromatographic-tandem mass spectrometric(LC-MS/MS)method for the determination of tegaserod in human plasma.Methods:Tegaserod and internal standard,diphenhydramine were isolated from plasma by liquid-liquid extraction.The chromatographic separation was achieved within 3 min on Zorbax XDB-C18 column(150 mm*4.6 mm,5 mum)with an isocratic mobile phase consisted of acetonitrile-5 mmol·L~(-1) ammonium acetate-formic acid(70∶30∶0.01)at the rate of 0.5 mL·min-1.Multiple reaction monitoring(MRM)transitions of 302173 and m/z256167 were measured in positive mode for tegaserod and the internal standard, respectively.Results:The linear concentration range of the calibration curve for tegaserod was 0.010~10 ng·mL~(-1).The lower limit of quantification was 0.010 ng·mL~(-1).The intra-and inter-day relative standard deviations(RSD)across three validation runs over the entire concentration range were less than 7.3%,the accuracies(RE)were within1.4%.After an oral dose of 6 mg,the pharmacokinetic parameters of tegaserod in test and reference tablets were as follows: Tmax(0.860.22)and(1.010.24)h,Cmax(2.210.69)and(2.050.64)ng·mL~(-1),t_(1/2)alpha(1.180.44)and(1.240.56)h,t1/2beta(10.103.07)and(8.812.35)h,AUC0~36 h(6.352.48)and(6.471.99)ng·h·mL-1,AUC0~(6.692.59)and(6.702.03)ng·h·mL~(-1),respectively.The relative bioavailability of tegaserod dispersible tablet was(98.222.1)%.Conclusion:The method was sensitive,rapid,accurate and suitable for bioequivalence study of tegaserod in human subjects. |
