An accurate, precise, simple, efficient and reproducible, isocratic Reversed Phase-High Performance Liquid Chromatography (RP-HPLC) method was developed and validated for the simultaneous estimation of Rosiglitazone and Glimepiride in bulk and combined pharmaceutical tablet dosage forms. Rosiglitazone and Glimepiride were separated by using a Symmetry ODS C18 (4.6mm×150mm) 5µm Particle Size; Waters Alliance e2695 HPLC system with 2998 PDA detector and the mobile phase contained a mixture of Methanol: 0.1% Orthophosphoric acid (64:36% v/v). The flow rate was set to 1ml/min with the responses measured at 224nm. The retention time of Rosiglitazone and Glimepiride was found to be 2.808min and 3.880min respectively with resolution of 5.68. Linearity was established for Rosiglitazone and Glimepiride in the range of 20-100µg/ml for Rosiglitazone and 60-140µg/ml for Glimepiride with correlation coefficient 0.999. The percentage recovery was found to be is 100.30% for Rosiglitazone and 100.21% for Glimepiride respectively. Validation parameters such as specificity, linearity, precision, accuracy and robustness, limit of detection (LOD) and limit of quantitation (LOQ) were evaluated for the method according to the International Conference on Harmonization (ICH) Q2 R1 guidelines. The developed method was successfully applied for the quantification of bulk and active pharmaceutical ingredient present and in combined tablet dosage form.
