Abstract: Buccal patches were found to be an efficient mucoadhesive drug delivery system and has the potential to produce pharmacological action that is equivalent to the action of similar drugs. Muco adhesive patches consist of active drug molecule and other additives such as polymers, softeners and permeation enhancers. Bioadhesive type of buccal patches would enhance the viscocity and would lead to validating the efficacy of the drug action. In this review we tried various types of buccal patches and recent advancements which were made to it for effective treatment of various heinous disorders.
