Buccal Mucosa as a Site for Drug Delivery

Buccal delivery of the drug with the help of mucoadhesive polymers has been extensively studied. There are various advantages of administering drug by this route. This review highlights the use of mucoadhesive polymers in buccal drug delivery along with the permeation enhancers and their mechanism. The article starts with the review of oral mucosa followed by theories of mucoadhesion, with a note on bioadhesive polymers and permeation enhancers, along with it covering the various factors affecting the drug delivery by this route and finally describing about the various kinds of dosage forms that can be administered by this route.
