Oral drug absorption enhancement by chitosan and its derivatives.
TL;DR: Mono-carboxymethylated chitosan (MCC) is a polyampholytic polymer, able to form visco-elastic gels in aqueous environments or with anionic macromolecules at neutral pH values, and appears to be less potent compared to the quaternized derivative.
