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.

A transdermal medication delivery system comprising means for retaining a medication in a form such that it is capable of being electrically charged; means for identifying the medication in said medication retaining means; means for supplying a d-c electrical current through said medication retaining means at a selected body location of a patient to be treated when said medication is in its electrically charged form, said medication retaining means and said body location forming an electrical current path for causing said medication to be delivered from said medication retaining means to said body location transdermally when said electrical current is so supplied; current control means for controlling the level of said electrical current in said current path; said control means, said medication retaining means, said body location, and said electrical current supplying means forming a closed loop during operation whereby said current is supplied in a controlled manner such that said current is generally maintained at a substantially constant level while said medication is being transdermally delivered to said body location and whereby said delivery can be terminated if said current level exceeds a selected maximum allowable level; and said control means further includes time control means responsive to said medication identifying means and to the substantially constant level of said electrical current for determining the treatment time over which said medication is to be delivered and for automatically terminating the delivery of said medication at the expiration of said treatment time.
