Abstract
An iontophoresis method for delivenng an active substance or drug to a target tissue which includes the step of sandwiching the target tissue between a donor electrode and receptor electrode which are each electrically connnected to a power source wherein a current path between the donor electrode and the receptor electrode is maintained at a minimum value to enhance delivery of the active substance to the target tissue.
