Enhanced anti-inflammatory effects of celecoxib from a transdermally applied nanoemulsion.

The aim of the present study was to evaluate the enhanced anti-inflammatory effects of celecoxib (CXB) from a transdermally applied nanoemulsion. The anti-inflammatory effects of an optimized nanoemulsion formulation were compared with those of conventional CXB gel and nanoemulsion gel on carrageenan-induced paw edema in rats. These tests were compared using the Dunnett test of one-way analysis of variance (ANOVA). The % inhibition value after 24 h application was significant for optimized formulation C2 (85.4%) compared with CXB gel and nanoemulsion gel (p < 0.05). These results suggest that nanoemulsions can be successfully used to enhance the anti-inflammatory effects of CXB.
