Abstract: Transdermal compositions for hormone replacement are comprised of exogenous hormones that are biochemically similar to those produced endogenously by the ovaries or elsewhere in the body. In this work, estradiol, estriol, and testosterone were loaded in transdermal vehicles, prepared using one of three selected penetration enhancer mixtures: Vehicle 1 (olive oil and oleic acid), Vehicle 2 (isopropyl palmitate and lecithin), and Vehicle 3 (isopropyl myristate and lecithin). The influence of penetration enhancers on transdermal delivery was evaluated using Franz-type diffusion cells and Normal Human 3D Model of Epidermal Tissue. Results showed that drug delivery is affected by the penetration enhancer used in the transdermal composition.
