Ursodiol is a bile acid derivative used as a medication for certain liver conditions and gallstone dissolution. It works by reducing cholesterol saturation in bile and promoting bile flow. Its primary therapeutic role is the treatment of primary biliary cholangitis and dissolution of cholesterol gallstones. The active ingredient functions by converting toxic bile acids into non-toxic forms and enhancing their transport out of liver cells. This biochemical action lowers inflammation and protects liver tissue from damage. Overall Ursodiol stabilizes liver function and improves patient outcomes in the targeted disease settings.

Ursodiol is a synthetic bile acid used to treat certain liver conditions. It works by replacing toxic bile acids that accumulate in diseases such as primary biliary cholangitis and primary sclerosing cholangitis. The medication binds to ileal transporters that normally reabsorb bile acids, reducing their recycle and promoting their removal. By altering bile acid composition, Ursodiol decreases inflammation and protects liver cells from injury. Its anti-apoptotic and anti-fibrotic actions are largely due to modulation of signaling pathways that regulate cell survival and extracellular matrix formation. Because it acts directly on bile acid metabolism, the drug provides a targeted therapeutic effect without changing systemic hormone levels. Overall Ursodiol improves liver function and slows disease progression in affected patients.

Ursodiol may cause diarrhea in some patients. Nausea and abdominal discomfort often accompany treatment. Headache can occur especially during the initial phase. Dizziness or lightheadedness has been reported in certain cases. Skin reactions such as rash may develop. Hair thinning or loss can be observed in a minority of users. Elevations of certain liver enzymes have been detected during routine monitoring. Fatigue or mild weight loss may accompany the medication.

Ursodiol is used to dissolve gallbladder stones and improve liver function. Common side effects include mild diarrhea, abdominal discomfort, and nausea. Rarely, it may cause allergic reactions such as rash or itching. Some patients experience elevated liver enzymes or temporary hair loss. The medication can interact with other drugs that affect the liver metabolism. Most side effects are reversible after stopping the treatment.
