Quality Evaluation of Generic Products of Metformin and Vildagliptin Tablets

The aim of the present study was the evaluation and comparison between four different Metformin and Vildagliptin tablets which are commercially available in Indian market. These tablets were assessed for various pharmacopoeial quality control tests. Parameters including weight variation, hardness, friability, drug content, and disintegration time were evaluated. Results were within acceptable limits for all selected products (three generic and an innovator). These results show that the tested generic products were biopharmaceutically similar to the innovator formulation. Therefore, the consumer can select any one of these equivalent products as a substitute for innovator product in case of cost concern or unavailability.
