Abstract:

The aim of the present work was to develop and optimize multiparticulate formulation viz. pellets of naproxen by employing QbD and risk assessment approach. Mixture design with extreme vertices was applied to the formulation with high loading of drug (about 90%) and extrusion-spheronization as a process for manufacturing pellets. Independent variables chosen were level of microcrystalline cellulose (MCC)-X 1, polyvinylpyrrolidone K-90 (PVP K-90)-X 2, croscarmellose sodium (CCS)-X 3, and polacrilin potassium (PP)-X 4. Dependent variables considered were disintegration time (DT)-Y 1, sphericity-Y 2, and percent drug release-Y 3. The formulation was optimized based on the batches generated by MiniTab 17 software. The batch with maximum composite desirability (0.98) proved to be optimum. From the evaluation of design batches, it was observed that, even in low variation, the excipients affect the pelletization property of the blend and also the final drug release. In conclusion, pellets with high drug loading can be effectively manufactured and optimized systematically using QbD approach.
