About Asimadoline

Asimadoline is an orally administered small molecule that is a highly selective kappa opioid receptor agonist. Kappa opioid receptors are found in the digestive tract and are believed to play an important role in control of visceral pain and bowel motility. Asimadoline was originally discovered by Merck KGaA of Darmstadt, Germany. In 2005, Tioga purchased asimadoline from Merck and acquired by assignment all worldwide rights. Asimadoline has been tested in over 1100 subjects and has demonstrated a promising safety profile.
