ABSTRACT:
An iontophoresis system includes an iontophoretic drug delivery device for placement against the skin of a patient and having at least one segmented electrode, and a circuit for controlling and equalizing current passing through each of a plurality of electrode segments. The current controlling circuit includes a plurality of constant current sources, each of which is electrically coupled to a corresponding one of the electrode segments. The constant current sources are selected such that substantially the same amount of current flows through each electrode segment independent of the impedance of the skin of the of the patient.
