Abstract:

Background: The drug delivery across buccal mucosa acts as very interesting option for the treatment of various oro-mucosal disorders such as aphthous stomatitis, periodontitis, gingivitis, toothache, periodontitis, and sjorgensen syndrome. But it is quite difficult because of target site movements, limited area for drug absorption, drinking of fluids, intake of food and salivary flow at regular interval contribute to poor retention and sub-therapeutic level of drug at target site. Due to this, mucoadhesive buccal drug delivery system has gained so much attention among the various scientists and researchers over the last two decades.

Methods: Mucoadhesion is a process of attachment between the natural or synthetic macromolecule and mucosal epithelial surface with the aid of interfacial attractive forces. The process of mucoadhesion has been extensively encouraged by utilization of mucoadhesive polymers within the formulation that on contact with salivary fluid swells and adheres to buccal epithelium membrane thus prolonging the drug release, retention time and improves therapeutic performance in case of oral diseases. The present review tried to covers the basic anatomy and structure of oral mucosa, pathways of drug absorption, theory of mucoadhesion, mechanisms involved in mucoadhesion and various factors affecting mucoadhesion.

Results: It highlights the properties of mucoadhesive polymers in drug delivery along with various dosage forms such as mucoadhesive tablets, films, patches, gels, and pastes. Furthermore, it also throws a light on recent developments made in the field of mucoadhesive buccal drug delivery system that reflects the potential of this system for the effective treatment of oro-mucosal disorders.

Conclusion: It can be concluded that mucoadhesive buccal drug delivery system has great potential in near future for treating the oro-mucosal disorders.
