TL;DR: The higher the degree of deacetylation of chitosan the more brittle and the less moisture absorption the films became, and transmission infrared and 13C-NMR spectra supported that Chitosonium acetate films prepared by a casting technique using acetic acid as a dissolving vehicle were chitOSoniumacetate films.

TL;DR: It was suggested that the swelling property, dissolution characteristics of the polymer films, pK(a) of drugs and especially drug-polymer interaction were important factors governing drug release patterns from chitosan films.

TL;DR: Pectin can be used as a mucoadhesive carrier for GI-mucoad adhesive drug delivery systems, and higher degree of esterification and molecular weight gave a stronger muco adhesion.

TL;DR: In this article, the performance of various pectins with different degrees of esterification and molecular weights was examined with porcine gastrointestinal (GI) mucosa, i.e. buccal, stomach, small intestine and large intestine, using a texture analyzer equipped with a mucoadhesive platform.

TL;DR: In this article, the authors investigated the effect of pectin-based hydrophilic matrix tablets on drug release and showed that the extent of matrix swelling, erosion and diffusion of drugs determined the kinetics as well as mechanism of drug release from pectina-based matrix tablets.
