Abstract | ||||
Stearic acid was used for the preparation of solid dispersion systems containing sodium Phanobarbitone in ratios of 1:2,1:1, 2:1 drug: carrier respectively. The dispersion prepared by melting and sudden cooling was passed through a set of standard sieves and tested for in vitro release rate. The release was slow for large particle size fractions and for systems containing high stearic acid content. A diffusional model was assessed for the drug release from the solid dispersion by a linear correlation observed between the percent release of the drug and the square root of time. | ||||
