Glycoursodeoxycholic acid is primarily used in the treatment of liver and gallbladder disorders. It helps dissolve cholesterol gallstones in patients who cannot undergo surgery, promoting bile flow and reducing cholesterol saturation in bile. Additionally, it is effective in managing primary biliary cholangitis, a chronic liver disease, by improving liver function and slowing disease progression. It also shows potential in treating certain metabolic and inflammatory conditions due to its cytoprotective and anti-inflammatory properties.
