Ursolic acid, ursodeoxycholic acid, is mainly used for the treatment of gallbladder stones, bile reflux, biliary obstruction, cholecystitis and so on. Ursodeoxycholic acid is mainly used to reduce the production of gallbladder stones by inhibiting the absorption of bile acids, promoting gastrointestinal peristalsis, reducing the accumulation of bile acids in the intestines, avoiding the crystallization of bile acids and reducing the production of gallbladder stones, and it can decompose the cholesterol-like gallstones and reduce biliary obstruction. In addition, Ursodeoxycholic acid can also promote the liver to secrete bile and reduce biliary stasis, which is used for cholestatic hepatitis caused by the liver, and its therapeutic effect is better. Oral administration of Ursodeoxycholic Acid is associated with adverse reactions such as nausea, vomiting, palpitations, dizziness, and fatigue. Patients must consult a physician before using the drug, under the guidance of the physician, avoid taking the drug on their own.
