Abstract
A transdermal medication delivery system in which the medication is retained in a non-charged form such that it can be electrically charged. A d-c electrical current is supplied through the retained medication when it is in its electrically charged form and current control is used to control the current level. The electrical current supply circuit, the control circuit, the retained charged medication, and the body location of a patient to which the medication is to be delivered transdermally, form a closed loop during operation so that the current is maintained at a substantially constant level while being delivered to the body location. Such delivery can be terminated if the current exceeds a maximum allowable level.
