FDA approves expanded use of Xifaxan

SILVER SPRING, Md. The Food and Drug Administration has approved a new use for a drug made by Salix Pharmaceuticals, the FDA announced Wednesday.

The agency approved Salix’s Xifaxan (rifaximin) for treating hepatic encephalopathy, a deterioration in brain functioning in patients with liver disease that results from the liver’s no longer being able to clear toxins from the body.

The drug already had approval for treating traveler’s diarrhea.

“The approval of Xifaxan for this new indication provides an additional treatment optin for patients with liver disease,” FDA Division of Gastroenterology Products deputy director Joyce Korvick said in a statement. “Hepatic encephalopathy occurs commonly in patients with liver disease, and there are few effective treatments for this serious condition.”
