Orexo was founded in 1995 by Thomas Lundqvist, a pharmacist, Anders Pettersson, a physician and clinical pharmacologist , and Christer Nyström, a pharmacist and Professor of Galenic Pharmacy at Uppsala University.
The company’s first product, Diabact® UBT – a breath test for diagnosing the stomach ulcer bacterium, Helicobacter pylori – was registered in 2000.
The name Orexo
In 2003 the company adopted the name Orexo, which derives from Greek and is the future form of the verb "orégo" - "to attain, to extend." Orexo also means appetite. New shareholders contributed financing, thereby raising the level of activity in the company. New development projects were started and a new company management was appointed to lead the company into the next phase.
In 2005, Orexo was listed on the Stockholm Stock Exchange. The company has since then entered into agreements with business partners and the development portfolio includes several potential drug candidates.
