1Simultaneous determination of amlodipine,valsartan and hydrochlorothiazide by LC-ESIMS/MS and its application to pharmacokinetics in rats显示文摘Polypill is a fixed-dose combination that contains three or more active ingredients used as a single daily pill to achieve a large effect in preventing cardiovascular disease with minimal adverse effects.A novel and accurate liquid chromatography tandem mass spectrometry method using electrospray ionization mode has been developed and validated for the simultaneous determination of amlodipine(AMD),valsartan(VAL) using losartan(LOS) as an internal standard(IS),and hydrochlorothiazide(HCT) using furosemide(FSD) as an IS.The separation was carried on Aquasil C_(18)(50 mm×2.1 mm,5μm) reversed phase column using acetonitrile and water containing 0.1%formic acid(50:50,v/v) as the mobile phase.The method was validated in terms of linearity,accuracy and precision over the concentration range of 1-1000 ng/mL.The intra and inter-day precision and accuracy,stability and extraction recoveries of all the analytes were in the acceptable range.This method can be successfully applied to the pharmacokinetic study of AMD,VAL and HCT when given as a polypill.Shankar Ganesh Gadepalli Pragney Deme Madhusudana Kuncha Ramakrishna Sistla 2014Journal of Pharmaceutical Analysis2014,4,6:5
