Preparation and Evaluation of Diclofenac Sodium Effervescent Tablet

The oral dosage forms are the most popular way of taking medicine although having some disadvantages like deliberate absorption and thus onset of action is extend. This can be overcome by administrating the drug in a liquid form i.e. effervescent tablet. The research is a formulation of diclofenac sodium as a effervescent tablet by wet granulation method. The bitter taste of the drug are masked by added sweetening agent (lactose, glucose etc.) In the present work we are prepared effervescent tablet in that we are used active drug diclofenac sodium and other active ingredient acid like tartaric acid and base sodium bicarbonate in different concentrations. The formulation of tablet was done by using wet granulation, wet granulation is found to be acceptable method of effervescent tablet formulation. The various pre-formulation studies was performed hardness, weight variation, disintegration, dissolution etc.
