Abstract
An efficient transdermal delivery system for delivering an active ingredient to the blood supply of a living body, comprising a vasodilator, an active ingredient, and a permeation enhancer for the active ingredient. The components of this mixture are combined in a manner that dissolves them into solution, eliminating the need for a polymeric binding agent and thus diminishing the total molecular weight of the mixture and increasing the penetration and delivery efficiency of the active drug molecules.
