Abstract: A novel composite membrane based on chitosan/starch/polyvinyl alcohol was prepared by solvent casting technique and its mechanical properties were measured. The drug release and its mechanism in static state from the composite membranes containing ciprofloxacin and protocatechuic acid have been investigated. The release rate was found to be controlled by the starch content in membrane matrices as well as by crosslinking state.

Key words: chitosan composite membrane, protocatechuic acid, ciprofloxacin, drug release
