ABSTRACT:
An iontophoretic system includes a medicament containing disposable patch removably attached to a patient's skin in combination with a controller mechanism. The patch includes an anode and a cathode, and holds an electrolyte and a medicament. The controller includes a controller circuit which is coupled to the cathode and is adjustable to provide a desired current flow through the electrodes to drive the medicament to the skin of the patient. The controller preferably includes a variety of functions to ensure safe and proper delivery of the medicament. The controller circuit is preferably an application specific integrated circuit (ASIC) so as to provide a compact controller having increased reliability and reduced power consumption.
