Disulfiram thermosensitive in-situ gel based on solid dispersion for cataract

Year: 2018

Type: article

Abstract: To improve the corneal permeability and water-solubility of disulfiram (DSF), which is an ocular drug for cataract, P188 was selected as a matrix to prepare solid dispersion of DSF (DSF SD ) by hot melt method. The DSF SD was characterized by DSC, XRD, and IR, and the results suggested that DSF was amorphous in DSF SD . The DSF SD was added to borate buffer solution (BBS) contained 20% poloxamer P407 and 1.2% poloxamer P188 to form in-situ gel. In vitro and in vivo experiments revealed that DSF SD combined with in-situ gel (DSF SD /in-situ gel) increased the residence time and the amount of DSF penetrated through the corneal. The pharmacodynamics studies exhibited DSF SD /in-situ gel delayed the development of selenium-induced cataract at some content. These results investigated that DSF SD /in-situ gel as a drug delivery system can improve DSF ocular permeability.
