Press Release

LONDON, ONTARIO -- (MARKET WIRE) -- May 06, 2010 -- Stellar Pharmaceuticals Inc. ("Stellar") (OTCBB: SLXCF), a Canadian pharmaceutical developer and marketer of high quality, cost-effective products for select health care markets, today reported signing an license agreement with medac GmbH ("medac") for the distribution and sale of one of its lead products, Uracyst® (a sterile sodium chondrotin sulfate solution, 2%) for the treatment of interstitial cystitis/painful bladder syndrome ("IC/PBS") in Germany and Austria.

Uracyst® is trademarked as Uropol® in Germany and Austria. With the approved CE mark for the product already in place, it is expected that medac will launch Uropol® in the third quarter of 2010. Under the terms of the agreement, medac will pay Stellar an upfront licensee fee in addition to a specified transfer price in exchange for the rights to an exclusive agreement for this territory. The agreement has an initial five-year term with additional two-year renewal periods.

"We are pleased to enter into this relationship with medac, a company that has a strong presence in the urology markets in Germany and Austria. We are confident that, with medac's support, Uracyst®/Uropol® will gain significant awareness, acceptance and adoption in these jurisdictions," said Peter Riehl, Stellar's President and Chief Executive Officer.

Mr. Riehl continued, "Germany is the single largest market in the European Community. Accordingly, this agreement not only represents an important revenue opportunity for Stellar and medac, but also offers hope for the first time to the thousands of German residents who are currently suffering from IC/PBS."

About Uracyst®

Interstitial Cystitis and Painful Bladder Syndrome are inflammatory diseases of the bladder wall, which cause pain, discomfort and frequent urination for those afflicted. There is no known cure for IC/PBS and currently approved products attempt to alleviate the symptoms of the disease. The quality of life for patients with IC/PBS is extremely poor, as they may need to void up to 60 times per day. Uracyst®, a sodium chondroitin sulfate solution, supplements and replenishes deficiencies in the glycosaminoglycan (GAG) lining of the bladder. The GAG lining acts as a protective barrier against irritants and toxins in the urine, and defends against bacterial adherence. Many researchers believe that more than 70% of patients with IC/PBS have deficient GAG layers allowing irritants and toxins in the urine to seep through this protective barrier causing an inflammation of the bladder wall.

Stellar currently markets Uracyst® directly in Canada and through license agreements in Denmark, Sweden, Norway, Finland, Iceland, the UK, Republic of Ireland, Netherlands, Italy, Turkey and now Portugal. Stellar also has out licensing agreements in place for Uracyst® in Israel, United States and China, territories which are each currently awaiting regulatory approvals.
