DESIGN, DEVELOPMENT AND OPTIMIZATION OF FAST DISSOLVING TABLET OF NEBIVOLOL HCL

The current research work involves preparation of fast dissolving tablets of nebivolol by direct compression method using different concentrations of superdisintegrants. A two-factor three-level (3 2 ) factorial design is being used to optimize the formulation. A total of 39 experimental run with 3 centre points were performed at all possible combination. The amount of % Disintegrating agent (X1), Diluents concentration (X2) and Disintigration agent (X3) were selected as independent variable three levels (+1, 0, −1). The disintegration time and hardness were selected as dependent variable. All the active blends the tablets were evaluated for post compression parameters (weight variation, hardness, and friability, wetting time, disintegration time, water absorption ratio, and in vitro drug release studies). Formulation was selected by the Design-Expert software which exhibited DT (26 sec) and hardness (4 kg/cm 2 ). It was concluded that fast dissolving tablets with high mechanical strength and rapid disintegration without the use of superdisintegrant could be prepared, which provide better patient compliance.
