Microspheres constitute an important part of the novel drug delivery system by virtue of their small size and efficient carrying capacity. Due to their
long residence time, bioadhesive characteristics mucoadhesion can be coupled to microspheres to develop mucoadhesive microspheres. Bioadhesion
can be defined as the state in which two materials, at least one of which is biological in nature, are held together for a prolonged time period by
means of interfacial forces. Microspheres are the carrier linked drug delivery system in which particle size is ranges from 1 to 1000 μm range in
diameter having a core of drug and entirely outer layers of polymer as a coating material. Mucoadhesive microspheres have advantages like efficient
absorption and improved bioavailability of the drugs due to a high surface to volume ratio, a much more intimate contact with the mucus layer,
controlled and sustained release of drug from dosage form and exact targeting of drugs to the absorption site. The present study aims to provide an
overview of various aspects of mucoadhesive microspheres, methodology of preparation of mucoadhesive microspheres, method of evaluation, and
their applications in drug delivery.
Keywords: Mucoadhesion, Mucoadhesive microsphere, Controlled release.
