In the present study fast dispersible nimodipine tablets were developed by direct compression method using quality by design (QbD) approach as per the central composite design by selecting avicel PH 102 (X1) and crospovidone (X2) as independent variables while % friability (R1), disintegration (R2) and hardness (R3) as output variables. Powder blends were assessed for flow characterization. At post compressional stage, several quality assessments were carried out. Particles morphology was observed using scanning electron microscopy (SEM). The stability study on the drug and optimized formulation were determined using thermal gravimetric analysis (TGA) and differential thermal analysis (DTA). RSM plots expressed the interaction of avicel PH 102 and crospovidone to determine the adequate quantities of excipients for the optimized formulation. Polynomial equations were used to validate the experimental design. The optimized formulations were evaluated for friability, disintegration and hardness. Results indicated that formulation (F4) containing avicel PH 102 (35%) and crospovidone (5%) was selected as best optimized formulation having friability 0.59%, disintegration 9 sec, % dissolution 95.703% and hardness 4.14 kg. Results of kinetics models indicated that all the developed formulations followed weibull model.
