Fast dissolving, fast melting, chewable and orally dissolving or disintegrating tablets are solid dosage forms that disintegrate rapidly and dissolve in the mouth withoutwater. The principle challenge with orally disintegrating tablets (ODTs) is to develop tablet formulations for standard direct compression processes that deliver rapid disintegration, pleasant mouth feel and high breaking force for tablet robustness. Superdisintegrant affect a range of formulation parameters, including the rate of disintegration, tablet breaking force, and mouth feel. The emphasis on the availability of drug highlights the importance of the relatively rapid disintegration of a tablet as a criterion for ensuring uninhibited drug dissolution behavior. Number of factors affects the disintegration behavior of tablets. The development of fast dissolving or disintegrating tablets provides an opportunity to take an account of tablet disintegrants. Superdisintegrants are generally used at a low level in the solid dosage form, typically 1 – 10 % by weight relative to the total weight of the dosage unit.
