( - Article Discussing Pharmacokinetics a...)Labopharm to Present Poster on Dose Titration of Once-daily,Tramadol at 3rd International Forum on Pain Medicine,Health

LAVAL, QC, June 29, 2007 /PRNewswire-FirstCall/ - Labopharm Inc. today announced that it will present a poster discussing the dose titration of its once-daily formulation of tramadol at the 3rd International Forum on Pain Medicine to be held June 28 to July 1, 2007 in Montreal, Canada.

The poster compares two different titration schedules for Labopharm's once-daily formulation of tramadol in three Phase III clinical trials: a six-day titration to a 300 mg dose (clinical trials MDT3-002 and MDT3-003) and a nine-day titration to a 300 mg dose (clinical trial MDT3-005). The comparison showed that percentage of adverse events and discontinuations due to adverse events was similar regardless of the titration schedule.

These results, in addition to the fact that Labopharm's once-daily tramadol formulation achieves steady state plasma levels after two days, suggest that a shorter titration schedule may be adequate for most patients. A previous study showed that most patients achieve pain control using Labopharm's once-daily tramadol at a dose of 200 mg. The data in this poster suggest that, for most patients, after starting with a dose of 100 mg for two days, the therapeutic dose of 200 mg could be achieved after two days without increased risk of side effects. If a patient requires a higher dose (300 mg), the therapeutic dose could be achieved after six days of titration (100 mg for 2 days; 200 mg for 3 days then 300 mg on the 6th day) without increased risk of side effects.

"The results of the comparison of titration periods reviewed in the poster suggest that patients may benefit from rapid titration to optimal analgesia without increased risk of side effects using our product," said James R. Howard-Tripp, President and Chief Executive Officer, Labopharm
