Many lipid-soluble medications can be delivered by diffusion across the skin. This process is called transdermal administration and is commonly done by applying patches that contain the medication to the surface of the skin. These patches can be attached anywhere on the skin except the palms of the hands and the soles of the feet. Why?
Thick skin slows the rate of diffusion of the medication and thus decreases its effectiveness. In addition, excessive sweat formed on the palms of the hands and soles of the feet would make the patch fall off more readily.
