1. A method for delivering an agent to a body site using iontophoresis, the method comprising:
- providing an agent in a controlled release formulation at or in proximity to a body site of an individual,positioning a first electrode at or in proximity to the site, the first electrode having a housing having an inner surface adapted to be in electrical communication with the site, and having an outer surface opposite the inner surface, and a second electrode in electrical communication with the site, the second electrode adapted to cooperate with the first electrode such that current passes between the first and second electrodes and through the site when the first electrode is in electrical communication with the power source, andregulating electrical communication between the electrodes to alter agent release from the formulation into the site.

Abstract
A method and apparatus for delivering an agent to structures of the eye or other body sites using iontophoresis applied through the eyelid, skin, etc. of a patient. A drug is introduced into the eye or other body site. A first electrode is in electrical communication with the site and a second electrode is positioned in relation to the first electrode. The electrodes are energized to generate a current between the electrodes and through the site that facilitates the selective dissemination of the agent throughout the eye or site.

15. A method for providing an agent to a body site using iontophoresis, the method comprising
providing an agent in a controlled release formulation at or in proximity to a body site of an individual, positioning a first electrode at or in proximity to the site, the first electrode having a housing having an inner surface adapted to be in electrical communication with the site, and having an outer surface opposite the inner surface, and a second electrode in electrical communication with the site, the second electrode adapted to cooperate with the first electrode such that current passes between the first and second electrodes and through the site when the first electrode is in electrical communication with the power source, and regulating electrical communication between the electrodes to provide a desired gradient of agent from the site at which agent is provided to the body site to be treated.
