A review on: mucoadhesive drug delivery systems

Mucoadhesive drug delivery systems interact with the mucus layer covering mucosal epithelial surface, and mucin molecules increase residence time of dosage form at site absorption. Over past few decades, has received a great deal attention. forms may be designed to enable prolonged retention application, providing controlled rate release for improved therapeutic activity. The mucoadhesive ability is dependent upon variety factors, including nature tissue physicochemical properties polymeric formulation. This review covers areas mechanisms theories mucoadhesion, factors influencing materials, polymers, also various forms.
