Eluxadoline is a locally acting mu opioid receptor agonist and delta opioid receptor antagonist for treating symptoms of diarrhoea-predominant irritable bowel syndrome (IBS-D).

"Eluxadoline could represent a significant advance in the treatment of IBS-D."

In connection with the completion of the Furiex acquisition, Actavis has also divested Furiex’s royalties on alogliptin and Priligy to Royalty Pharma for a payment of approximately $415m.

Actavis president and CEO Brent Saunders said: "If approved, eluxadoline could represent a significant advance in the treatment of IBS-D, and would give Actavis one of the broadest product offerings for the $38bn GI disease market.

"This product, if successful, would make Actavis even more relevant to gastroenterologists and primary care physicians in meeting significant patient needs."
