Chlorhexidine release from ethylcellulose films east from solvents of different dichloromethane/ethanol compositions was studied. Release rate was proportional to the square root of time. Increased ethanol content within the casting solvent significantly enhanced release rate. Release rate and cumulative mass released at different time periods (5, 10, 15 and 25 days) were proportional to the solubility parameter of the casting solvent.
