Abstract:


Background: The present work was aimed to develop an ethosomal gel of naproxen sodium for the amelioration of rheumatoid arthritis.

Objective: In the present work we have explored the potential of ethosomes to deliver naproxen into deeper skin strata. Further the anti-inflammatory efficacy of naproxen ethosomal formulation was assessed using carrageenan-induced rat paw edema model.

Methods: Naproxen sodium nanoethosomes were prepared using different proportions of lipoid S100 (50mg-200mg), ethanol (20- 50%) and water, and were further characterized on the basis of vesicle morphology, entrapment efficiency, zeta potential, in-vitro drug release and ex-vivo permeation studies.

Results: The optimized ethosomal formulation was having 129±0.01 nm particle size, 0.295 polydispersity index (PDI), -3.29 mV zeta potential, 88% entrapment efficiency and 96.573% drug release in 24 hours. TEM and SEM analysis of the optimized formulation showed slightly smooth spherical structures. The Confocal laser scanning microscopy showed that ethosomes could easily infiltrate into deeper dermal layers (upto 104.9µm) where as hydroalcoholic solution of drug could penetrate upto 74.9µm. Further the optimized ethosomal formulation was incorporated into 1% carbopol 934 gel base and optimized wherein the transdermal flux was found to be approximately 10 times more than hydroethanolic solution. Also the in–vivo pharmacodynamic study of the optimized ethosomal gel exhibited higher percentage inhibition of swelling paw edema than marketed diclofenac gel.

Conclusion: The ethosomal gel was successfully developed and has shown the potential to be a good replacement option for the conventional therapies of rheumatoid arthritis.
