Abstract Background Vildagliptin is an antidiabetic agent, belongs to the dipeptidyl peptidase IV (DPP-4) inhibitors. Objective The aim of investigation was to develop a simple UV-visible Spectrophotometric method for the determination of vildagliptin in its pure form and pharmaceutical formulations, further to validate the developed method. Material and Methods Vildagliptin was estimated using UV-Visible double beam spectrophotometer at the wavelength of maximum absorption (210 nm) in acidic medium containing 0.1N HCl. The drug was characterized by melting point, Differential Scanning Calorimetry (DSC), and Fourier Transform Infra-Red (FTIR) techniques. The analysis of the drug was carried out by novel UV-Visible method which was validated analytical parameters like linearity, precision, and accuracy as per guidelines laid down by International Conference on Harmonization (ICH). Result Melting point of drug was found 154°C which is corresponds to its actual melting range. Similarly by the interpretation of spectra the drug was confirmed. The linear response for concentration range of 5–60 µg/ml of vildagliptin was recorded with regression coefficient 0.999. The accuracy was found between 98–101%. Precision for intraday and interday was found to be 1.263 and 1.162 respectively, which are within the limits. To establish the sensitivity of the method, limit of detection (LOD) and limit of quantification (LOQ) were determined which were found to be 0.951 µg/ml and 2.513 µg/ml respectively. Conclusion The UV method developed and validated for vildagliptin drug was found to be linear, accurate, precise and economical which can be used for the testing of its pharmaceutical formulations.
