Abstract : BackgroundAtopic dermatitis(or eczema) can be defined as a chronic inflammatory condition accompanied with severe pruritus.ObjectiveThe prepared gel was evaluated for in-vitro drug release, in vitro occlusion studies, transepidermal water loss studies, skin permeation studies, in-vitro skin irritation studies and anti-inflammatory cell line studies.MethodsIn vitro drug release studies were performed using Franz diffusion cells.The in vitro occlusion studies were carried out by the procedure reported by Wissing et al. TEWL determination was done by the method proposed by Reiger. The skin permeation studies were carried out using porcine skin using Franz diffusion cells. In-vitro skin irritation study were carried out using HET-CAM (Hen’s Egg Test on the Chorioallantoic Membrane) method. Anti-inflammatory cell line studies were carried out using RAW 264.7 cell lines.ResultsIn-vitro drug release studies,drug release of nicotinamide from nanoemulsion gel was found to be more than marketed gel. Kinetic modelling showed a higuchi model with non- fickian diffusion. In vitro occlusion study showed the percentage of evaporated water from prepared nanoemulsion formulation after 72 hours is very less compared with the other formulations. The TEWL measurement shows the reduction in TEWL has more in prepared nanoemulsion gel than other formulations.Anti-inflammatory cell line studies proved that the nanoemulsion gel have inhibition capacity on COX activity,LOX activity, Inducibe nitric oxide synthase and cellular nitrate levels.ConclusionDha oil based nicotinamidenanoemulsion gel were prepared successfully and the evaluation of prepared gel showed better drug release and skin permeation with better anti-inflammatory activity.
