This article includes requirement for orally disintegrating tablets, orally disintegrating films, chewing gums, oral wafers and buccal patches ,their advantages,disadvantages,challenges in formulation ,patented technologies, various technologies developed for formulated orally disintegrating dosage form ,super disintegrating agents in the formulation, evaluation method and various marketed products.
