Uses
What is ursodiol used for?
Ursodiol is commonly used for the following conditions.
- To break down gallstones (gallbladder stones)
- To prevent gallstones from forming in people with obesity who are rapidly losing weight
Ursodiol can also be used to treat primary biliary cholangitis (PBC), a disease where the bile ducts in your liver get damaged.
Ursodiol may also be used for other conditions as determined by your healthcare provider.
How does ursodiol work (mechanism of action)?
Bile acids are components of bile, which is a fluid made in your liver that helps with digestion. Ursodiol is a type of bile acid that your body naturally forms in small amounts. When you take ursodiol as a medicine, it changes your bile so that cholesterol (a main component of gallstones) can easily dissolve. This helps dissolve gallstones that have already formed and prevent new ones from forming. If you have primary biliary cholangitis (PBC), ursodiol replaces the type of bile acid that builds up and damages the liver.
How is ursodiol supplied (dosage forms)?
