The nanocapsules were prepared by the interfacial deposition technique proposed in the year 1989. The required quantity of the drug and benzyl benzoate were mixed and added dropwise in the organic phase containing the polymer PLGA dissolved in the two organic solvents. With continuous stirring at 4000rpm for 1 hour, soyalecithin was added in the above mixture. Finally, the later was added in the solution of Polaxamer 188 with a continuous stirring speed of 4000rpm for 30 minutes. Fine concentrated colloidal dispersion of paracetamol nanocapsules were obtained after the removal of organic solvents and high-speed centrifugation. Then anocapsules were characterized by scanning electron microscopy, zeta potential and particle size analysis. The compatibility of the excipients was analysed by FTIR. The nanogel of paracetamol was formulated with carbopol 934 and triethanolamine as the major ingredients. The transdermal formulation was tested for its in vitro permeation studies through the biomimetic dialysis membrane using Franz diffusion cell and entrapment efficiency was also conducted. The receiver solution was phosphate buffer (pH 7.4) and the permeability study was carried out for 12 hours. The transdermal gel was subjected to accelerated stability tests for 6 months and after this period microbiological tests were performed for common microorganisms. The qualitative and quantitative estimation of viable microorganisms present in the gel was evaluated which includes tests for total viable count (bacteria and fungi) and specified microbial organisms (Escherichia coli, Salmonella typhi, Pseudomonas aeruginosa and Staphylococcus aureus). The accelerated stability study showed that the product is stable for the period of 6 months. The microbiological assay established the absence of common microorganisms. Transdermal gel formulation containing paracetamol can be prepared by the interfacial deposition technique using Carbopol 934 as a carrier. In vitro drug release data showed better physiochemical characteristics with no skin irritation reactions. Moreover, the accelerated stability test and the microbiological tests assured a stable product.
