Due to limited water solubility of cyproterone acetate and also limited skin permeation; lipid base nanocarriers with different size ranges were considered for topical delivery of cyproterone acetate. Lipid nanoparticles were prepared by solvent diffusion evaporation technique. Different variables including; surfactant/lipid ratio. mixing rate and addition time of organic phase to aqu... https://www.countryscenesaddleryandpetsuppliers.shop/product-category/toe-downs/
