Bioadhesiveness of thiolated pectin for buccal delivery of carbenoxolone sodium

摘要

Pectin is a biopolymer that has numerous useful purposes in food and beverage industry, cosmetic products and pharmaceutical fields. One of the important properties of pectin is its bioadhesive properties. Native pectin provides fair bioadhesive properties that can be improved by modification of pectin structure. The immobilization of thiol groups on polymer can significantly improve the bioadhesive properties due to in situ cross-linking between thiol groups of polymer and mucin [1].
