Search for: [Abstract = "m different kinds of excipients were characterised in terms of shape, porosity, size distribution and dissolution behaviour. Dissolution studies of solid dispersion pellets showed enhancement in the dissolution rate of drugs. The increase in the amount of released drug from solid dispersions pellets was greater than from the pellets containing drug alone. After 20 minutes almost total amount of ketoprofen and indomethacin was dissolved from pellets. In the case of piroxicam the best results were obtained by using the layering method in pellets formulation. The amount of piroxicam dissolved from these pellets was two times greater than from pellets obtained by extrusion spheronisation. The dissolution profiles of drugs from pellets were unchanged after one year storage."]
