The Mouth, consists of two regions, the vestibule and the oral cavity proper. The vestibule is the area between the teeth, lips and cheeks. The oral cavity is bounded at the sides and in front by the alveolar process (containing the teeth) and at the back by the isthmus of the fauces. Its roof is formed by hard palate at the front, and a soft palate at the back the uvula projects downwards from the middle of the soft palate at its back. The floor is formed by the mylohyoid muscles and is occupied mainly by the tongue. The oral cavity and oropharynx are spaces defined by both hard and soft tissue structures Mucoadhesion, the state in which two materials, amongst which one is biological in nature, adhere to each other for extended periods of time with the help of interfacial forces, provides an attractive strategy to overcome the hurdles of conventional drug delivery systems including first pass metabolism, and localized delivery of biomolecules including proteins, peptides and oligonucleotides. In addition mucoadhesion also makes it possible to obtain prolonged, local or systemic drug action. In this review we discussed about potential applications of mucoadhesion and mucoadhesive polymers in drug delivery along with the mechanism of mucoadhesion and the methods for evaluation of mucoadhesive drug delivery systems.
