Materials which are used in making of effervescent Tablets are hydroxy-methylcellulose HPMC. For the buoyancy sodium bicarbonate is used. Initially for the selection of formulation Definitive screening design is used which allows to study the effect of large number of factors in relatively small experiment. The optimized formulation is tested for release rate, buoyancy, hardness, thickness, floating time, swelling study and release rate. These studies shows that optimized tablet remains in stomach for 24h and shows release rate of 91% which is very desirable.
