Improved dissolution and anti-inflammatory effect of ibuprofen by solid dispersion

Liyuan Chen, Qifeng Dang, Chengsheng Liu, Jun Chen, Lei Song, Xiguang Chen

Frontiers of Medicine 2012, Volume 6, Issue 2,   Pages 195-203 doi: 10.1007/s11684-012-0189-3

Abstract:

The purpose of this study was to improve the dissolution rate and anti-inflammatory effect of ibuprofenby a solid dispersion (SD) method.The dissolution of ibuprofen in urea was higher than in PEG4000 or mannitol.Solid dispersion-based (SDBT) and conventional (CT) tablets were prepared by the wet granulation method In vitro release results indicated that the ibuprofen dissolution rate was improved by the
