Mucoadhesive drug delivery systems
نویسندگان
چکیده
Drug actions can be improved by developing new drug delivery systems, such as the mucoadhesive system. These systems remain in close contact with the absorption tissue, the mucous membrane, releasing the drug at the action site leading to a bioavailability increase and both local and systemic effects. Mucoadhesion is currently explained by six theories: electronic, adsorption, wettability, diffusion, fracture and mechanical. Several in vitro and in vivo methodologies are proposed for studying its mechanisms. However, mucoadhesion is not yet well understood. The aim of this study was to review the mechanisms and theories involved in mucoadhesion, as well as to describe the most-used methodologies and polymers in mucoadhesive drug delivery systems.

متن کاملMucoadhesive Vaginal Drug Delivery System: a Review on Advance Status
Mucoadhesive delivery systems offer several advantages over other oral controlled release systems by virtue of prolongation of residence time of drug, its targeting, and localization of the dosage form at a specific site. These advantages include bypass of first pass metabolism of the drug and hence more concentration of the drug is available for absorption. Mucoadhesion occurs between two surf...

The purpose of current article focuses on polymers used in mucoadhesive drug delivery system. The term “mucoadhesive” is defined as the “attachment of drug elongated with asuitable carrier like natural or synthetic polymer to mucus and/or an epithelial surface”. It is a popular novel drug delivery system because relatively permeable of mucous membranes, and mucus have higher blood flow therefor...

متن کاملMucoadhesive drug delivery system: An overview
Mucoadhesive drug delivery systems interact with the mucus layer covering the mucosal epithelial surface, and mucin molecules and increase the residence time of the dosage form at the site of absorption. The drugs which have local action or those which have maximum absorption in gastrointestinal tract (GIT) require increased duration of stay in GIT. Thus, mucoadhesive dosage forms are advantage...
