Aim: The design and development of pranoprofen (PF) nanostructured lipid carriers (NLCs) for topical treatment of local inflammation and pain. Materials & methods: PF-NLCs were designed and optimized by central rotatable composite design. A physicochemical characterization was addressed. Release and skin permeation were performed in Franz diffusion cells. in vivo anti-inflammatory efficacy was assayed in mice and tolerance study in humans. Results: PF-NLCs F7 and F10 provided sustained release, good stability and optimal skin retention avoiding systemic undesired side effects. Anti-inflammatory activity was enhanced, suggesting an improved efficacy as compared with standard formulation. No skin irritancy was detected. Conclusion: Topical PF-NLCs F7 and F10 could be effective and safe new therapeutic tools for the treatment of local inflammation and pain. [GRAPHICS] .
