MDNU Medical Nutrition Usa (MM)

Medical Nutrition USA, Inc. (NASDAQ: MDNU), a developer and distributor of proprietary, nutrition medicine products, announced the introduction of Pro-Stat� AWC with Citrulline. The product, which is an enhanced formulation of Pro-Stat� AWC, is designed for patients in long-term care facilities with advanced wounds, primarily pressure ulcers.

Pressure ulcers, also know as bedsores, can significantly diminish quality of life and require substantial cost to remedy. Also, statistics show the incidence of bedsores to be as high as one-in-four among long-term care residents, with a price tag for treatment of $1.3 billion nationally.

Pro-Stat� AWC with Citrulline is the only wound care supplement with Citrulline, an amino acid that safely and effectively increases Arginine levels to produce nitric oxide needed for wound healing. Nitric oxide is used by the inner lining of blood vessels to relax the surrounding smooth muscle, resulting in a widening of blood vessels and increased blood flow to the wound.

A clinical study, conducted by S. Kwon Lee MD, FACS, and published in the journal Advances in Skin & Wound Care in 2006, of long-term care residents with pressure ulcers showed a 96% improvement in healing rates among those residents that received standard care plus Pro-Stat� compared to a control group that received standard care plus a placebo.

"Pro-Stat� AWC with Citrulline is an even more effective treatment option for patients with pressure ulcers," said Frank A. Newman, Medical Nutrition USA's Chairman and Chief Executive Officer. "This important addition to the Pro-Stat� product line demonstrates Medical Nutrition USA's continuing dedication to developing significant and highly-effective new products on a timely basis."
