moreBackground of the study: The prime objective of any work in pharmaceutical plant, whether in production or quality control is to manufacture product of requisite quality at the lowest possible cost. Validation is attaining and documentation of sufficient evidence to give reasonable assurance that the process under consideration does and what it purports to do. Methods: In the present study, process validation studies were carried out for a bilayer tablet containing extended release Metformin, Pioglitazone and Glimepiride as per the protocol. The parameters used during the studies were dispensing, sifting, mixing, preparation of granulating solution, granulation, drying and sizing, lubrication (flow property & assay lubricated granules), compression (weight variation, hardness, thickness, friability, content uniformity), labeling and packing. Results and Discussion: The samples collected at different stages were analyzed using UV and HPLC method as per protocol. The results were found to be within the acceptance criteria. Conclusion: From the validation studies carried out, it was observed that no modification was required in present manufacturing process. The method requires further validation only when there is change in raw materials or equipment or process.
