Press release, July 29, 2008

The FDA has accepted for filing the registration application for Sublinox™

The submitted registration application for SublinoxTM (OX22) has been accepted by the FDA as complete for substantive review after initial evaluation. SublinoxTM contains the wellknown active substance zolpidem and is based on Orexo's sublingual technology, involving a rapidly disintegrating tablet placed under the tongue.

Meda AB acquired the exclusive world-wide commercialization rights for SublinoxTM on April 14, 2008. "This FDA's acceptance increases the chances for a registration approval during 2009", said Anders Lönner, CEO of Meda.

The data supporting the product includes a clinical study in insomnia patients that was completed in October 2007. That study showed that SublinoxTM induced sleep 30 percent earlier compared to Ambien® and that patients remained asleep throughout the night with comparable safety.

"This is an important first step to get SublinoxTM out on the world markets" said Torbjörn Bjerke, Orexo's President and CEO.
