Abstract
A percutaneous drug delivery system, method, and kit are disclosed. The method comprises applying an enzyme preparation to a localized area of skin for a predetermined amount of time to enhance that area of skin's permeability to selected drugs, occluding the area of skin during the application, and then applying the selected drug(s) to the area of skin to allow the drug to penetrate through the skin and into the circulatory system of the animal. Greatly enhanced penetration of chemicals through the skin results from the enzyme treatment.
