Abstract

This invention is a portable iontophoresis apparatus (10) for facilitating delivery of medication across the cutaneous membrane into adjacent underlying tissues and blood vessels. The apparatus employs a modular, detachable non-reusable medicament containing applicator electrode (12) which is adapted to attach to a base assembly (11). The apparatus is designed to be hand held, and includes a circumferential tactile electrode band (20) on the base assembly (11) which provides electrical connection between the skin of the user's hand and one pole (24c) of a bipolar power source (24) housed within the base assembly (11). The opposing pole (24a) of the power source is connected to the applicator electrode (12). The user's body completes the electrical circuit between the applicator and tactile electrodes. A method for using the device for the treatment of Herpes simplex infection, and related viral infections, which produce similar cutaneous lesions, is presented. The apparatus, when used in accordance with the method described herein, demonstrated > 90% treatment efficacy in clinical trials.
