Abstract
Transdermal administration of hydrophobic drugs via a diffusion mechanism in which the drug is dissolved in a carrier at concentrations that are 20% to 80% of the saturation concentration. The flux of drug from the device is non-Fickian and is substantially greater than the flux observed when the drug is at saturation.
