SIMULTANEOUS DETERMINATION OF CLOPIDOGREL AND PIOGLITAZONE BY HIGH PERFORMANCE LIQUID CHROMATOGRAPHY IN BULK DRUG AND DOSAGE FORMS

Abstract

A high performance liquid chromatographic method with UV detection was developed and validated for simultaneous determination of Pioglitazone and Clopidogrel. Separation was performed on a C18 column by isocratic elution with a mobile phase of Methanol: Acetonitrile : Water (80:10:10) at pH 4.6. The UV detection was set at 230 nm. The method proved to be specific, accurate, precise and linear over the concentration ranges of 20-120ppm for both Pioglitazone and Clopidogrel with correlation coefficients always >0.999 for both drugs. The intra-day and inter-day precision and accuracy were less than 2 for both analytes.
