In the present study, we select the Sylysia 350 (Sylysia) as mesoporous material, distearoylphosphatidylethanolamine-poly(ethylene glycol) 2000 (DSPE-PEG) as absorption enhancer and hydroxy propyl methyl cellulose (HPMC) as crystallization inhibitor to prepare sorafenib tosylate (SFN) nanomitrix (MSNM@SFN) for improving the anti-tumor activity of SFN. The MSNM@SFN was prepared by solvent evaporation method. The solubility, dissolution, and bioavailability of SFN in MSNM@SFN were also

Our results indicated that the solubility and dissolution of SFN in MSNM@SFN were significantly increased. The oral bioavailability of SFN in MSNM@SFN was greatly improved 7.7-fold compared with that in SFN suspension. The enhanced anti-tumor activity of MSNM@SFN was confirmed in vitro and in vivo experiments. This nanomatrix developed in this study could be a promising drug delivery platform for improving the therapeutic efficacy of poorly water-soluble drugs.
