Labopharm and Paladin Complete Canadian Licensing and Distribution Agreement for Labopharm's Once-Daily Tramadol Product

Product Expected to Fulfill Need Not Currently Met in Canadian Pain Treatment Market

LAVAL, QUEBEC and MONTREAL, QUEBEC--(Marketwire - July 12, 2007) - Labopharm Inc. (TSX:DDS)(NASDAQ:DDSS) and Paladin Labs Inc. (TSX:PLB) today announced that they have completed a licensing and distribution agreement under which Labopharm has granted Paladin the exclusive right to market and sell Labopharm's once-daily tramadol product in Canada. Labopharm will retain co-promotion rights.

"With sales and marketing expertise specific to the pain and central nervous system areas and a strong commitment to our product, Paladin is the right marketing partner for our once-daily tramadol in Canada," said James R. Howard-Tripp, President and Chief Executive Officer, Labopharm Inc. "We believe that our once-daily tramadol product will fulfill a need not currently being met within the pain treatment landscape in Canada."

"With considerable sales potential, Labopharm's once-daily tramadol will become the flagship product in our pain portfolio," said Jonathan Ross Goodman, President and Chief Executive Officer of Paladin Labs Inc. "We look forward to launching this unique product into the large and growing Canadian pain treatment market, which in 2006 reached almost 26 million prescriptions representing sales of more than $800 million."

Under the terms of the agreement, Labopharm will receive a transfer price on packaged product supply based on a percentage of the anticipated selling price. Labopharm expects to generate a gross margin on Canadian sales in excess of what the Company is currently experiencing in Europe. Labopharm will also receive up front and milestone payments of up to $1.5 million from Paladin.

The two companies expect the product to be launched in Canada this year.

About Labopharm's Once-Daily Tramadol Product

Labopharm's once-daily tramadol product is based on the Company's proprietary Contramid® technology, which provides a dual matrix delivery system allowing both rapid and sustained drug release that maintains blood levels within the therapeutic range providing a full 24 hours of pain relief. The Company believes that maintaining drug concentrations within the therapeutic range has the advantage of fewer and less severe side effects while maintaining efficacy. Under its global commercialization program, Labopharm's once-daily tramadol product has been approved in 28 countries and a broad European launch is underway.

About Tramadol

Tramadol is a centrally acting analgesic for the treatment of moderate to severe pain. Tramadol has a 30-year history of efficacy and safety and is currently marketed in more than 70 countries worldwide, primarily in formulations that require multiple doses per day. Studies have shown that tramadol provides relief from both acute and chronic pain conditions, including osteoarthritis pain, low back pain, cancer pain, post-operative pain and dental pain. Tramadol avoids the potentially serious side effects such as gastrointestinal bleeding that may be caused by NSAIDs and the potential cardiovascular events recently attributed to COX-2 inhibitors. Compared to stronger opioids, tramadol has, in clinical studies, demonstrated a lower incidence of major side effects, such as respiratory depression.
