Abstract

An electrode for an iontophoretic drug delivery system includes a retainer having a malleable characteristic. The retainer and a conductor are connected to a platform. The conductor and a dose controller are electrically coupled to the iontophoretic drug delivery system. A drug delivery matrix is operably connected to the platform and proximate the conductor wherein the conductor, the drug delivery matrix, and the dose controller cooperate to deliver a drug to a user when the electrode is affixed to the user and operably connected to the iontophoretic drug delivery system.
