Labopharm's Once-Daily Tramadol Approved for Sale in Canada

Company in Discussions to Complete Canadian Licensing and Distribution Agreement for Once-Daily Tramadol Product

LAVAL, QC, June 18 (HSMN NewsFeed) - Labopharm Inc. (TSX: DDS ; NASDAQ: DDSS ) today announced that it has received a Notice of Compliance (NOC) from the Therapeutic Products Directorate (TPD) of Health Canada for 100 mg, 200 mg and 300 mg tablets of its once-daily formulation of tramadol for the management of pain of moderate severity in adults who require treatment for several days or more. The NOC allows the marketing and sale of Labopharm's once-daily tramadol product in Canada.

"With more than 26 million prescriptions written for pain products in 2006, the Canadian market represents an important component of our global commercialization plan for our once-daily tramadol product," said James R. Howard-Tripp, President and Chief Executive Officer, Labopharm Inc. "We believe that our once-daily tramadol product offers physicians and patients an efficacious and safe option for treatment of pain of moderate severity, with the added benefit of once-a-day dosing."

Labopharm's New Drug Submission (NDS) to Health Canada for its once-daily formulation of tramadol included data from the Company's global clinical development program, including six Phase III clinical studies in which 14 Canadian centers participated, and 12 pharmacokinetic studies. Combined, more than 2400 patients have been administered the product in clinical studies.

Labopharm is in active discussions to complete a licensing and distribution agreement for its once-daily tramadol product in Canada, under which the Company will retain the right to co-promote the product to certain specialties through its own sales force. Labopharm expects the product to be launched in Canada later 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 27 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.
