Popis: Drugs of different solubilities were incorporated into porous cellulose matrices (PCMs) by solvent evaporation. The rate of release of the drugs from the PCMs was found to decrease with increasing drug concentration and decreasing drug solubility. At low or moderate drug concentrations, the release rate remained moderately high except for drugs of very low solubility. The mechanisms controlling release rate appeared to include diffusion within the matrix but may be more complex.
