【 摘 要 】

Solid dispersion is an attractive tool of pharmaceutical technology used to improve the physical properties of drugs. Among these properties is to enhance the solubility of the drugs.Rebamipide is a poorly soluble drug of class IV of biopharmaceutical classification system (BCS).Rebamipide is used as potent antiulcer, mucoprotective drug, by stimulating the generation of prostoglandine enhanced mucosal protection.Rebamipide was formulated as a solid dispersion using different polymers such as pluronic F-127, PEG6000, PVP K30, and TPGS by using different preparation methods solvent evaporation, fusion, and kneading methods.It was seen that rebamipide was successfully dispersed in a homogenous solid dispersion matrix by solvent evaporation method using TPGS (1:15) drug carrier ratio.Moreover, the results revealed that the solubility of rebamipide (23.9µg/ml) increased significantly (p?0.05) by 36.4 x fold to obtain 874µg/ml solubility in rebamipide matrix. On the other hand, characterization of rebamipide solid dispersion using FTIR, DSC, SEM and x-ray diffraction demonstrated no drug polymer interaction, and converting the rebamipide from crystal to amorphous state lattice.
