RESUMEN
OBJECTIVE:To prepare Geinstein (GEN) solid dispersion,and improve the dissolution rate of GEN in vitro. METHODS:Using PVP K30,PEG6000,and PEG4000 as carriers,GEN solid dispersion was prepared by solvent melting meth-od,and its dissolution in vitro was investigated. The structure of the solid dispersion was characterized by FTIR and DSC. RE-SULTS:GEN solid dispersion prepared with PEG4000 as carrier was better than those with other carriers in dissolution,and drug-carrier ratio (1:5) was the best. The results of DSC and FTIR showed that GEN in solid dispersion took amorphous form. CONCLUSIONS:GEN solid dispersion is prepared successfully and significantly improve the dissolution of GEN in vitro.
