Primary biliary cholangitis (PBC) is a chronic type of liver disease that can gradually destroy bile ducts. These ducts deliver bile from the liver to the small intestines, to help your body digest fats and certain vitamins. When bile ducts are destroyed by PBC, bile stays in the liver and damages liver cells, which can cause cirrhosis (scarring of the liver) and lead to liver failure. PBC is a slow progressive disease that may have no symptoms for many years. Treating PBC to keep the liver functioning normally can allow for a normal life expectancy.
Obeticholic acid is used to treat PBC. This medicine is sometimes used together with another drug called ursodeoxycholic acid (UDCA).
Obeticholic acid was approved by the US Food and Drug Administration (FDA) on an “accelerated” basis. In clinical studies, patients with PBC responded to obeticholic acid. However, further studies are needed to determine if this medicine can improve survival or disease-related symptoms.
Obeticholic acid may also be used for purposes not listed in this medication guide.
