Screening of drug-sericin solid dispersions for improved solubility and dissolution.

The aim of present attempt deals with preparation of binary dispersion of sericin, waste of sericulture industry in order to enhance solubility and dissolution of poorly soluble drugs. Solid dispersions (SDs) of BCS-II drugs were prepared by spray drying, solvent evaporation, ball milling and physical mixing in ratio of drug:sericin (1:0.5, 1:1, 1:1.
