Optimization of Process Parameters for Formulation of Fluvastatin Tablet by Using Dry Granulation Method

Abstract

The manufacturing process of the tablet is a very complex process; it can be affected by the several process parameters or variables. The aim of this study was to understand and optimize the process parameters such as mixing, granulation, lubrication and tablets compression processes using quality by design (QbD) approach for a model Anti- Hyperlipidemic drug Fluvastatin sodium. During the processes there are several parameters which may influence or affect product quality. So the main objective of present work was to identify various process parameters and optimize this parameter, for the formulation of good quality product which needs to optimize Blending time, Roller force, Compression force and machine speed. A scale up batch was taken to evaluate and optimize the parameters. Critical quality attributes (CQA) such as flow behavior, granules parameters, Blend uniformity, tablet appearance, effect on tablet quality like physical appearance (surface, weight etc.) and tablet dissolution time as well as drug release.  The test results of following parameters at various in-process phases are complies with the specified limits and finished product sample results were found to be within specified limits. This study results assures the manufacturing process is reproducible, robust and will yield consistent product, which meets specification.
