ABSTRACT:
An iontophoretic controller is provided. The controller is electrically connected via two electrical connectors to a patch consisting of two electrodes, the two electrodes are respectively positioned in an active reservoir and a return reservoir of the patch. A current is applied to the patch when the iontophoretic controller is turned on or otherwise activated. A waveform, such as the patch voltage, is measured over a predetermined time interval. A change in the measured voltage is compared to a threshold. If the change in measured voltage exceeds the threshold, the controller takes an action, such as providing a warning or discontinuing the application of current.
