Eco-Friendly UV Spectrophotometric Method for Simultaneous Estimation of Evogliptin and Metformin Hydrochloride in Bulk and Combined Tablet Dosage Form

Evogliptin (EGT) is used in fixed-dose combination with metformin hydrochloride (MFH) for a better glycemic control in Type 2 diabetes mellitus. To date, no method is available for simultaneous estimation of these drugs. In the present study, an UV spectrophotometric method was developed in distilled water, an environment-friendly solvent using the simultaneous equation technique to simultaneously determine EGT and MFH in bulk and tablet dosage form. The developed method was validated and applied to commercial tablet dosage forms containing EGT and MFH in combination. With a great correlation value (R2>0.998), the analytes displayed good linearity in the range of 10-100 μg mL-1. The low percent relative standard deviation proved the methods' precision. The methods' accuracy was demonstrated by excellent recovery. Thus, the developed method was found to be simple, environment-friendly, fast, specific, precise, and accurate, and it may be effectively used for routine analysis of EGT and MFH in bulk and their combined tablet dosage form.
