Abstract
An iontophoretic drug delivery device includes a controller normally being in an off or low power consumption state, and a patch including electrodes, a reservoir for holding an ionizable drug for transdermal delivery to a patient and a return reservoir. The patch is removable and electrically connectable to the controller, and delivers the drug to patient when the patch is on the patient's skin and when the controller is switched from the off or low power consumption state to an operational state. This occurs when the patch is connected to the controller and a connector connects a power source to the controller or an activation means signals the controller to switch to the operational state. This feature preserves the battery of the controller.
