ABSTRACT:
An iontophoresis drug delivery system includes a device which is attachable to the skin of an animal and having a drug reservoir, an electrolyte reservoir, and electrodes electrically communicating with the reservoirs and with the skin of the animal. An electronic circuit for controlling the rate or amount of current or voltage applied to the electrodes of the device includes a constant voltage and current generator, and a switching circuit for switching between applying either a constant current to the electrodes or a constant voltage. Current and voltage sensors are attached to the electrodes and provide feedback signals which are compared with predetermined threshold signals to control through feedback the amount of constant voltage and constant current applied to the electrodes.
