Operations

"For the full year 2010, we saw strong sales of Abstral, providing an increase of approximately 320%. Sales of Edluar also grew, particularly in the fourth quarter.

On January 10, 2011 Abstral was approved by the FDA for sale in the United States. As a result of the approval and the new distribution agreements signed with Newbridge for the Middle East and Africa and Invida for the remaining key markets in Asia and Australia, Abstral is now a global product.

In August Orexo launched their new strategy "Orexo 2015". It is based on developing and commercializing products in-house in the future. In the first program, OX-219 (for the treatment of opioid dependence) has already completed a positive Phase I trial. Clinical phase I trials have been initiated in the other two new programs, OX27 and OX51.

Orexo's arachidonic acid research made significant progress during the year.

Orexo also achieved its first milestone for OX-MPI in the research collaboration with Boehringer Ingelheim, "says Anders Lundström, President and CEO.
