ABSTRACT:
An electrically powered transdermal iontophoretic delivery device (10, 20) and a method of making same is provided. The device utilizes electrode assemblies (8, 9) composed of a substantially homogenous blend of a polymeric matrix containing about 5 to 50 vol % of a conductive filler which forms a conductive network through the matrix, and up to about 50 vol % of the agent to be iontophoretically delivered through the skin. In the case of the donor electrode assembly, the agent is typically a drug and preferably a water soluble drug salt. In the case of the counter electrode assembly, the agent is typically an electrolyte salt. The homogenous blend eliminates the need for separate electrode and agent containing layers which require lamination.
