MDNU Medical Nutrition Usa (MM)

Medical Nutrition USA, Inc. (NASDAQ: MDNU) today announced it signed an exclusive agreement with DSE Healthcare Solutions, LLC to market its Proantinox� product to U.S. retail outlets.

The 10-year Trademark License Agreement gives DSE the right to utilize intellectual property, including trademarks, patents and formulation, relating to Proantinox�, Medical Nutrition's urinary tract cleansing complex, in return for royalty payments based on sales to the retail market. Medical Nutrition will continue to market the product to the institutional market under the UTI-Stat(TM) brand. Proantinox� (UTI- Stat(TM)) is a liquid urinary tract cleansing complex developed by Medical Nutrition that has been shown to be effective in reducing recurrent urinary tract infections.

"We are pleased to partner with DSE, whose retail offerings include Cystex�, a dual-action urinary tract analgesic that is complementary to Proantinox� and is carried by most major food, drug and mass market retailers. We believe that the co-marketing of Proantinox� with the Cystex� brand will hasten its acceptance and broaden distribution beyond what would have been achieved independently," said Frank A. Newman, Medical Nutrition's Chairman and Chief Executive Officer.

DSE markets leading specialty health products through a number of national and regional retail outlets including Walgreen's, CVS, Rite Aid, Walmart, Target stores, Duane Reade, Safeway, Winn Dixie and Giant Foods.

"Proantinox� is a great product that is well accepted in the institutional market and we are excited about the opportunity to bring it to the retail market," said Moaiz Daya, DSE's Chief Executive Officer. "We think the addition of Proantinox� to the Cystex� line makes for a very powerful two-punch approach to urinary tract infections."
