Drug-release systems, chitosan

Chitosan has been widely used as matrix in drug-release systems in the form of beads and granules, as promising vehicles for oral drug sustained-release formulations [164]. [Pg.531]

The chemical modification of chitosan is a powerful tool to control the interaction of the polymer with drugs, enhance the load capability, and tailor the release profile of the drug carriers. Chemically modified chitosan improves its bulk properties for the preparation of sustained drug release systems. Many studies in this context have been reported in the literature. [Pg.174]

Chitosan and hydroxypropylchitosan were found to be enzymatically degraded so that they can be used for implantable controlled-release dosage forms. Due to the moieties of chitosan (i.e., amine and hydroxyl groups), chitosan can be cross-linked or complexed with citric acid, EDTA, or glutaraldehyde, and the cross-linked or complexed chitosans have been applied to drug delivery systems. [Pg.494]
