| Abstrakt: | Since the early 1980s the concept of mucoadhesion has gained considerable interest in pharmaceutical technology. The various advantages associated with these systems made buccal drug delivery as a novel route of drug administration. It prolongs the residence time of the dosage form at the site of application. These systems remain in close contact with the absorption tissue, the mucous membrane, and thus contribute to improved and/or better therapeutic performance of the drug and of both local and systemic effects. This review highlights the anatomy and structure of oral mucosa, mechanism and theories of mucoadhesion, factors affecting mucoadhesion, characteristics and properties of desired mucoadhesive polymers, various types of dosage forms, and general considerations in design of mucoadhesive buccal dosage forms, permeation enhancers, and evaluation methods. Lay Abstract: Over the past few decades the mucoadhesive buccal drug delivery system has received a great deal of attention to develop mucoadhesive dosage forms to enable the prolonged retention at the site of action, providing a controlled release of drug for improved therapeutic outcome. Mucoadhesive drug delivery gives facility to include a permeation enhancer/enzyme inhibitor or pHmodifier in the formulation and versatility in designing as multidirectional or unidirectional release systems for local and systemic action. Local delivery to tissues of the oral cavity has a number of applications, including treatment of local conditions such as periodontal disease, bacterial and fungal infections, and aphthous stomatitis and vesiculo bullous diseases. For the treatment of chronic diseases, the mucoadhesive buccal drug delivery system allows easily accessibility and is generally well-accepted for administeringdrugs by systemic action. |
