Indian drugsSummary: In the present research work, celecoxib (CXB) loaded solid lipid nanoparticles (SLNs) were prepared using the probe sonication method, wherein Glyceryl monostearate and Tween 80 were used as solid lipid and surfactant, respectively. To obtain the statistically optimized batch, 32 factorial design was applied. The optimized batch was characterized physicochemically and evaluated through DSC, SEM and XRD studies. The mean particle size of the optimized batch was found to be 135.41± 0.24 nm with a mean % entrapment efficiency of 80 ± 1.69%. The optimized batch was further lyophilized and dispersed into 1% w/v Carbopol 934P to form a gel. Prepared gel was further evaluated for in vitro drug release, occlusivity, ex vivo permeability, local toxicity, in vivo anti-inflammatory activity and accelerated stability study. The study resulted in stable, safe and prolonged anti-inflammatory activity with quick onset of action. Hence, celecoxib loaded solid lipid nanoparticles can be considered as promising alternative to conventional topical systems.
