Abstract

A simple, sensitive, rapid, economic, UV Spectroscopic method was developed for the estimation of Sitagliptin-Metformin in Pure and Tablet dosage forms. The linearity for Metformin was found between 200-400 μ/ml and between 20-45 μ/ml for Sitagliptin. Metformin showed the maximum absorbance at 232nm & Sitagliptin at 266nm and Validation parameters like Precision, Accuracy, and System suitability parameters were determined and examined by applying validated parameters.
