Abstract
An iontophoresis device in which at least one of the electrodes is a composite electrode containing a polymeric binder, a powdered or fibrous conductive filler and a divided material capable of being consumed by electrochemical oxidation or reduction. The binder of the composite electrode consists of a polymer containing 10-100 mo % of 1,2-epoxypropane and/or 1,2-epoxybutane, and 40-0 mol % of at least one other monomer that is copolymerizable with such oxides. The device is useful for transcutaneously delivering active principles to a patient.
