IBAT inhibitors are used to treat itching caused by progressive familial intrahepatic cholestasis (PFIC) and Alagille syndrome. IBAT inhibitors work by blocking the ileal bile acid transporter (IBAT), which helps reduce the buildup of bile acids in the liver. These medications are available in oral forms, making them easy to take. Examples include Bylvay (odevixibat) and Livmarli (maralixibat). You can choose the form that best fits your needs.
