A comparative study was done by the authors between the active substance release characteristic of lipophilic and hydrophilic oitment bases and their rheological parameters. There was stated a significant difference due to the matrix concentration the last being an essential factor in determining the effective surface area. The water solubility of matrix constituents is plaxing an important role in formation of the effective surface area.
