UV Spectrophotometric Method for Simultaneous Marketed Brand Gibtulio Met Fixed Dose Combination Tablets

A validated UV spectrophotometric method has been developed for the simultaneous quantification of Gibtulio Met (12.5/500mg) Fixed Dose Combination dosage forms using the simultaneous equation method. This approach is based on measuring the absorbance of Metformin HCl and Empagliflozin within the concentration ranges of 2-10 μg/ml and 0.1-5 μg/ml, respectively, at their respective λ max values of 235 nm and 225 nm. The linearity correlation coefficients for Metformin HCl and Empagliflozin in these concentration ranges were 0.999, and 0.9998 respectively. The results were statistically validated in compliance with ICH guidelines. Keywords: Metformin, Empagliflozin, ICH guidelines
