摘要：
The release kinetics of caffeine and potassium chloride (KC1) representing poorly soluble and water-soluble drugs from polyvinylpyrrolidone (PVP) matrices were studied using different mathematical models. Dissolution parameters obtained from the release data were employed to characterize the effect of drug loading on the release kinetics. The deviations observed from the predicted values for these parameters were explained using percolation theory as well as the release kinetics of the matrix material itself.
