Development and validation of simple and rapid LC-MS/MS method for ezetimibe in human plasma and its application to bioequivalence study
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2017, Vol 17, Issue 2
Abstract
A sensitive and specific liquid chromatography combined with electrospray ionization (ESI) tandem mass spectrometry (LC-MS/MS) method, operating in the negativeionization mode, for quantifying of ezetimibe in human plasma using ezetimibe-d4 as internal standard (IS) was developed and validated. The analyte and IS were extracted by simple one step liquid to liquid extraction (LLE). The chromatographic separation was performed on a Gemini C18 column (50 X 2.0 mm, 5 um) under isocratic conditions using a mixture of acetonitrile/0.1% formic acid (70:30, v/v) as mobile phase at a flow rate of 0.20 ml/min. Quantitation was performed using multiple reaction monitoring (MRM) mode to study parent → product ion transitions of m/z 408.0→270.8 for ezetimibe and m/z412.1→270.8 for IS, respectively. Linearity in plasma was obtained over the concentration range 0.1 ~ 20 ng/ml, with a coefficient of determination (r2 ) of 0.9999. The method was has been successfully applied for routine assay to support pharmacokinetic study of ezetimibe in human plasma after an oral administration of 10 mg ezetimibe.
