The aim of the present study was to investigate the nanoemulgel as transdermal delivery system for poorly water soluble drug, ketoprofen, in order to overcome the troubles associated with its oral delivery. Different nanoemulsion components (oil, surfactant, and cosurfactant) were selected on the basis of solubility and emulsification ability. Pseudoternary phase diagrams were constructed using titration method to figure out the concentration range of components. Carbomer 940 was added as gel matrix to convert nanoemulsion into nanoemulgel. Drug loaded nanoemulsions and nanoemulgels were characterized for particle size, TEM, viscosity, conductivity, spreadability, rheological behavior, and permeation studies using Wistar rat skin and stability studies. Transdermal permeation of ketoprofen from nanoemulgels was determined by using Franz diffusion cell. Nanoemulgel containing 6% oleic acid as oil, 35 …
