Labopharm receives notification of regulatory approval in France for once-daily tramadol

01-19-2005: Labopharm Inc. announced that it has received notification of regulatory approval for its once-daily formulation of tramadol from the French regulatory authority. The product has been approved with a once-daily designation for use in a dose range from 100 to 400 mg per day in the treatment of moderate to severe pain.

Together with the French regulatory authority, Labopharm has been preparing its submission to initiate the MRP process for its once-daily tramadol product. In addition, the Company is working to obtain pricing and reimbursement approval in France. Labopharm is also working closely with each of its European partners to finalize preparations for commercial launch of its product.

The European market for tramadol is large and growing with sales for the 12-month period ended September 2004 exceeding US$570 million, representing a compound annual growth rate of 18% over the previous five 12-month periods. In France, the largest European market for tramadol, sales exceeded US$160 million for the 12-month period ended September 2004, representing a compound annual growth rate of 26% over the previous five 12-month periods.
