Generic Name: Ursodeoxycholic acid
Product Name: Ursofalk


Ursofalk is used in the treatment of chronic liver disease in which the flow of bile has stopped for some reason (eg. primary biliary cirrhosis, primary sclerosing cholangitis and cystic fibrosis-related cholestasis.


The main ingredient of Ursofalk, ursodeoxycholic acid, is a substance that appears naturally in the body. It is used to treat cholestatic liver disease, although the mechanism is not fully understood.

Ursodeoxycholic acid alters the composition of bile, increasing concentrations of itself and decreasing amounts of toxic bile acids. It also increases bile flow.

There is some evidence that ursodeoxycholic acid may also act via an immunological mechanism, details of which are not fully understood.
