Norwich Pharmaceuticals has submitted to the US regulator for approval to market a generic version of Xifaxan (rifaximin), a treatment for irritable bowel syndrome.

The move could mean imminent competition for Canada’s Bausch Health (TSX: BHC) and its gastroenterology business Salix Pharmaceuticals.

Bausch acquired Salix in 2015, for $14.5 billion. Apart from Xifaxan, the buy added several key treatments for gastrointestinal conditions to Bausch’s portfolio, including Apriso (mesalamine) and Uceris (budesonide), for ulcerative colitis.
