Xifaxan is a gastrointestinal-specific oral antibiotic. The Food and Drug Administration ( FDA) approved Xifaxan 200 milligram for the treatment of patients 12 years of age and older with travelers’ diarrhea caused by noninvasive strains of E coli.

The Company is exploring potential additional indications, formulations, clinical trials and co-promotion arrangements to capitalize on the potential for Xifaxan, including its development program in irritable bowel syndrome.

In October 2012, the USPTO declared an interference action to determine the priority of invention between Cipla’s application related to amorphous rifaximin and Solmag SpA’s application directed to amorphous rifaximin.
