Development and Validation of RP-HPLC method for Simultaneous Estimation of Metformin and Pioglitazone

Uttam kumar Agrawal, Jeyabalan Govindasamy


A new simple, accurate ,precise and reproducible RP-HPLC method has been developed for
simultaneous estimation of metformin and pioglitazone in bulk drug form using proper HPLC
system. The mobile phase consists of phosphate buffer and acetonitrile in the ratio of 35:65 at
pH 3.4.The detection wavelength was carried out at 228 nm. The method was linear over the
concentration range for metformin 50-100 μg/mL and for pioglitazone 20-180 μg/mL. The
recoveries of metformin and pioglitazone were found to be 100.5 and 98.7% respectively. The
validation of method was carried out utilizing ICH-guidelines. The described HPLC method
method was successfully for the analysis of pharmaceutical formulations containing dosage
