Abstract
The present invention comprises a composition comprising a matrix (,) adapted to be placed in drug- and permeation-enhancing mixture-transmitting relation to a selected skin (,) or other body site. The matrix (,) contains sufficient amounts of drug, permeation enhancer(s) and poly-N-vinyl amide to continuously administer to the site, the drug, in a therapeutically effective amount, and the permeation-enhancing mixture, in an amount effective to enhance the permeation of the skin (,) to the drug, the device (,) shows increased transdermal flux as compared to the transdermal flux of the drug from a device (,) containing no poly-N-vinyl amide. Incorporating poly-N-vinyl amide into the transdermal system also improves the adhesion and stability of the system.
