Iontocaine

SALT LAKE CITY--(BUSINESS WIRE)--July 9, 1998--IOMED(R) Inc. (AMEX:IOX) Thursday announced the release of its newest generation of iontophoretic dose controller, the Numby(R) 900.

This new controller with simple push button operation delivers fast and effective local dermal anesthesia when used in conjunction with IOMED's Numby Stuff(R) electrodes and IONTOCAINE(R)(a), IOMED's anesthetic medication.

The Numby 900 is a component of IOMED's iontophoretic drug delivery system, which is the needle-free way of delivering certain types of medications into and through the skin using a mild, low-level electrical current from a small battery-operated, dose controlling unit.

The compact, portable design of Numby 900 makes delivering local dermal anesthesia simple for clinicians. The Numby 900 offers:

Simple, effective push-button controls

Pre-programmed dose with variable current options for fast, easy

operation

Integrated state-of-the-art electronics for maximum patient

comfort, safe drug delivery and proven IOMED reliability

The device performs internal checks before and during each treatment. Audible and visual alarms are activated if any problems are detected or if the battery needs replacement. Treatments may also be stopped manually at any time.

The Numby 900 is used in combination with IOMED's pediatric pain management product, Numby Stuff, which is used to numb an area of the skin prior to painful local procedures. Numby Stuff delivers anesthesia in as little as 10 minutes and numbs the skin and underlying tissue up to a depth of 10 millimeters.

"The Numby 900 is easy to use, allowing physicians or nurses to operate the dose controller by pushing a single button," said Ned M. Weinshenker, Ph.D., IOMED's president and chief executive officer. "In addition, the compact size and portability of the device is ideal to treat pediatric patients or to allow for mobility while patients are receiving treatments."
