Using Quality by Design to Develop Fixed-Dose Combination Tablets

In the present investigation, the fixed-dose combination (FDC) tablet of Atorvastatin calcium and Ezetimibe was prepared by a quality-by-design approach using 2³ factorial design. Precompression and post-compression parameters were determined indicating excellent flow properties of granules as well as good tableting characteristics of the final tablets. Dissolution study showed higher drug release nearly 80% within 30 min for all prepared batches attributed to conversion from crystalline to amorphous form of the drug. ANOVA studies revealed that there was a linear correlation between the predicted, and the observed responses gave higher values of r², indicating excellent fitting of the model (P < 0.001). Thus, the prepared FDC tablet executed a good relationship between selected critical formulation parameters and critical quality attributes. The drug release rate obtained met the selected dissolution criteria.
