Abstract
This invention is directed to a novel formulation for effectively utilizing hydrophobic permeation enhancers for the increased permeability of active agents through the skin or mucosa along with reduction of the lag time between application of the active agent and attainment of a therapeutically effective agent flux, with little or no irritation to the host. The invention is directed to compositions containing a hydrophobic permeation enhancer, which permeation enhancer has been micronized and stabilized in an inert carrier such as water. These compositions can be combined with a biologically active agent to provide enhanced permeability of the active agent to the skin or mucosa.
