Abstract

The prevalence of diabetes is increasing day by day as per a report by the year 2045, 1 out of every 8th individuals may suffer from diabetes. This research article focuses on developing and validating Metformin and Dapagliflozin in combination by using high-pressure liquid Chromatography (RP-HPLC). The validation of the method was followed as per the guidelines provided by the International Conference on Harmonization (ICH) and United States Pharmacopeia (USP). Separation of both drugs takes place in less than 4 min. This separation takes place using Phosphate buffer (pH 6.8) and acetonitrile in a 45:55 (v/v) ratio at a 1.0 mL min−1 flow rate. Furthermore, studies on both drugs were conducted by using the bulk and pharmaceutical dosage forms (Tablets). The developed method was accurate as drug recoveries in both cases of Metformin, and Dapagliflozin ranged between (100.8, 99.6, 98.8%) to (100.8, 99.3, and 101.5%) respectively having a concentration range of solutions between 70, 100 and 130 μg mL−1 dilution. The recommended method for simultaneous quantification of Metformin and Dapagliflozin was established and validated and no excipient interactions were found.
