In vitro release and characterization of chitosan films as dexamethasone carrier.

Chitosan, a biodegradable and biocompatible polysaccharide, is a potentially useful material in various fields. We produced mono and bilayer chitosan films containing dexamethasone as a drug carrier for controlled release. The chitosan drug-loaded films were produced by a casting/solvent evaporation technique using 2 wt% acetic acid solution and distilled water and they were dried at room temperature.
