A simple, specific, accurate, precise and stability-indicating RP-HPLC method was developed and validated for the simultaneous estimation of metformin HCl and canagliflozin in pharmaceutical formulation. The method was developed using the Altima C8 column (150 ×4.6 mm, 0.5 μm) with a mobile phase consisting of acetonitrile and 0.1 % orthophosphoric acid in water (62:38 %V/V) with a flow rate of 1 mL/min. Detection was carried out at 254 nm using a PDA detector. The retention time for metformin HCl and canagliflozin was found to be 2.282 and 3.339 min, respectively. The proposed method was validated for linearity, range, accuracy, precision, robustness, LOD and LOQ. Linearity was observed over a concentration range 15-225 μg/mL for metformin HCl (r2 =0.9995) and 5-40 μg/mL for canagliflozin (r2 =0.9988). The % RSD for intraday and interday precision was found to be 0.13 and 0.20 for metformin HCl and 0.18 and 0.20 for canagliflozin. The LOD and LOQ were found to be 0.16 μg/mL and 0.54 μg/mL for metformin HCl and LOD and LOQ were found to be 0.05 and 0.21 μg/mL for canagliflozin. Metformin HCl and canagliflozin were subjected to stress conditions of degradation including acidic, alkaline, oxidative, thermal and photolysis.

Development And Validation

The present work demonstrates a simple, rapid, precise, specific, and sensitive reverse-phase high-performance liquid chromatography (RP-HPLC) method for analyzing glimepiride in pure and tablet forms. The present method was developed using a C18 column 150 × 4.6 mm, with 5 μm, and packing L1 maintained at a temperature of 30°C. The mobile phase was prepared by dissolving 0.5 gram of monobasic sodium phosphate in 500 mL of distilled water, pH of the solution adjusted to 2.1 to 2.7 with 10% phosphoric acid, and added 500 mL of acetonitrile. The mobile phase was pumped in the highperformance liquid chromatography (HPLC) system at a flow rate of 1 mL/min, and separation was carried out at 228 nm, using an ultraviolet (UV) detector. The chromatographic separation was achieved with peak retention time (RT) at about 9.30 minutes, and the method was found to be linear over a concentration range of 40 to 140 μg/mL. The specificity of the method represented no interference of the excipients during the analysis, and stability testing after 24 hours also showed that the method is suitable and specific. The accuracy was between 99.93 to 99.96%, with limit of detection (LOD) and limit of quantitation (LOQ) being 0.354 μg/mL, 1.18 μg/mL, respectively. Satisfactory results were found for precision and robustness parameters during the development and validation stage for the analytical method. The proposed method was also adopted for the analysis of glimepiride tablets to improve the overall quality control. Using this method, symmetric peak shape was obtained with reasonable retention time. The retention time of glimepiride for six repetitions is 9.3 ± 0.1 minutes; the run time is 21 minutes. The proposed RP-HPLC method is a modification of the United States Pharmacopeia (USP) method, and it was found to be valid for glimepiride within concentration ranges 40 to 140 μg/mL, using C18 analytical columns, and isocratic elution with UV detection, and at 1 mL/min of flow rate.
