ABSTRACT:
An iontophoretic drug delivery system having a patch including a medicament containing surface, and a controller having circuits which supply electric current to effect the iontophoretic drug delivery. The patch is detachably coupled to the controller and includes a plurality of spaced-apart electrical contacts. The controller includes an elastomeric connector which is made of alternating sections of electrically conductive and electrically non-conductive material. The electrically conductive material of the elastomeric connector is coupled to the controller circuiting. During transcutaneous drug delivery, the patch is connected to the controller such that the electrically conductive sections of the elastomeric connector are also coupled to respective spaced-apart electrical contacts of the patch so that the controller can control the rate and duration of the drug delivery.
