Online published on 18 September, 2017. Abstract A new, simple, accurate and sensitive UV-spectrophotometric absorption correction method has been developed for simultaneous determination of Metformin HCl and Empagliflozin in bulk utilizing concept of standard addition. The method is based upon determination of Empagliflozin at 224 nm & Metformin HCl at 230 nm methanol as a solvent. Overlay spectra of both drugs shows absorbance at 227 nm. Linearity was observed in range of 10–50 μg/ml and 1–3 μg/ml for Metformin HCl and Empagliflozin respectively. The correlation coefficient value was found to near to 1. All methods were statistically validated as per ICH guidelines.
