Evaluation of the Mechanical Properties and Drug Permeability of Chitosan/ Eudragit RL Composite Film

The aim of this study was to design and evaluate a chitosan-based film which has required properties for successful wound dressing and can control drug penetration and maintenance time in the location. Several formulations of film containing chitosan (3%) and different concentrations of Eudragit RL (0.5, 1 and 1.5%) were prepared by using casting/solvent evaporating technique. Mechanical properties, water vapor transmission rate (WVTR), oxygen permeability (OP), water uptake and nitrofurazone permeability through the films were investigated.
