The kinetics of controlled release of medicinal substances from chitosan films has been investigated. Correlation between values of coefficients diffusion and shares of medicinal substance connected with a polymeric chain has been established. It was shown that the greater proportion of the medicinal substance connected with a polymeric chain, the lower the value of diffusion coefficients and the index defining process of diffusion in the chitosan films, and the slower transport of medicinal substance from a polymeric matrix.
