IOMED Introduces New Dose Controller.

SALT LAKE CITY--(BW HealthWire)--July 23, 1999--

IOMED, Inc. (AMEX: IOX) today announced the introduction of the Phoresor(R) PM900 dose controller into the rehabilitative medicine market for the treatment of acute inflammatory conditions. The Phoresor PM900, which incorporates the Company's latest iontophoretic drug delivery technology, operates at the touch of a button to reduce set-up time and improve the efficiency of iontophoretic drug delivery treatments.

The unit is pre-programmed for a 40mA-minute dose with 2.0, 3.0 and 4.0mA current setting options. The current can be adjusted any time during the treatment and the treatment time is automatically adjusted. The Phoresor PM900 features include:

- Simple push-button controls - Pre-programmed 40mA-minute dose with variable current options for

straight-forward, easy operation - Compact and portable design - Integrated state-of-the-art electronics for safe drug delivery

The one-touch controls of the Phoresor PM900 offer clinicians quick set-up time and make it easier for patients to adjust the current based on their comfort level. In addition, the Phoresor PM900 is compatible with both IOGEL(TM) and TransQ(R) drug delivery electrodes. IOMED's proprietary electrodes stabilize the pH of the drug without using chemical buffers, and offer conformability and conductivity with the skin surface using a patented GelSponge(TM) element.

"The introduction of the Phoresor PM900 dose controller is another step in IOMED's continued commitment to offer the most advanced iontophoretic drug delivery technology available," said Robert J. Lollini, vice president, finance and chief financial officer. "By providing improved convenience and efficiency for both clinicians and patients, the Phoresor PM900 should further enhance the Company's competitive position and support continued growth in product sales."

Iontophoresis is a non-invasive method of transporting water-soluble ionic drugs into and through the skin using mild electric current. Treatable conditions include acute local inflammatory conditions, such as carpal tunnel syndrome, lateral and medial epicondylitis, plantar fasciitis and other musculoskeletal inflammatory conditions. Iontophoresis is also used to induce rapid, local dermal anesthesia using IOMED's Iontocaine(R) (lidocaine HCI 2% with epinephrine 1:100,000 Topical Solution).

IOMED, Inc. is a leader in the research, development and manufacture of iontophoretic drug delivery systems, which are marketed to healthcare providers worldwide. Iontophoretic drug delivery involves the transport of water-soluble ionic drugs into and through the skin using a mild electrical current. IOMED also conducts advanced research for local and systemic delivery of ionic pharmaceutical compounds to treat various medical conditions.
