Abstract
A wearable iontophoresis device for the prolonged delivery of a positively charged pharmaceutical species from a salt formulation is disclosed that includes a readily oxidizable metal-based sacrificial anode in the form of a generally planar layer having a connecting area that has a width that is sufficient to insure complete consumption of the oxidizable metal wherein the anode is configured to have a minimum operating life of at least 6 hours under skin-safe conditions, and a drug delivery gel pad in electrical contact with said anode for accommodating a gel containing a positively charged pharmaceutical species in salt form formulated for transdermal delivery.
