Atorvastatin

Simvastatin

LC-MS/MS

Atorvastatin,a chemical([R-(R*,R*)]-2-(4-fuorophenyl)-b,ddihydroxy-5-(1-methylethyl)-3-phenyl-4-

[(phenylamino)carbonyl]1 H-pyrole-1-heptanoic acid),is a synthetic HMG-CoA(3-hydroxy-3-methylglutaryl-coenzyme A) reductase inhibitor.It has been shown to be remarkably effcacious in decreasing the level of cholesterol and triglyceride [1].In order to quantify the level of atorvastatin in plasma,it needs a sensitive,rapid and selective method.As per the literature,several LC–MS/MS methods have been reported for the determination of atorvastatin in human plasma[2].

This research developed a method to quantify atorvastatin in human plasma.Simvastatin was used as internal standard.Atorvastatin and simvastatin were extracted by liquid–liquid extraction using ethyl acetate.The analytical separation was performed using Acquity?UPLC BEH C18,100×2.1 mm, 1.7 μm.The mobile phase used gradient elution of 0.2%formic acid in acetonitrile,with fow rate of 0.3 mL/min.The analysis was carried out by multiple reaction monitoring(MRM)in positive mode using precursor to product combination of m/z 559.05>440 for atorvastatin and m/z 419.15>199.05 for simvastatin.The method had a chromatographic run time of 5 minutes and linear calibration curve over the range of 0.2–100 ng/mL with a correlation coeffcient(r)of 0.9998.All the validation parameters fulflled the criteria[3]and the method can be successfully applied for pilot bioequivalence studies of three formulations of atorvastatin.
