Abstract
A new, simple, accurate, precise and reproducible UV-Spectrophotometric method is being developed for the simultaneous estimation of Metformin Hydrochloride and Voglibose in tablet dosage form. The stock solutions were prepared in methanol. The λmax for Metformin Hydrochloride and Voglibose were found to be248 nm and 287nm respectively. The Metformin Hydrochloride and Voglibose obeyed Beer’s law in concentration range of 8-16µg/ml and 4-20µg/ml respectively. Results of analysis of absorbance ratio method were analysed and validated for various parameters according to ICH guidelines for accuracy, precision, linearity, robustness, LOD and LOQ. The proposed method is highly sensitive, precise and accurate, therefore can be used for intended purpose.
