| Physical and Chemical Properties | This product is white powder; Odorless, bitter taste. Mp 200-204 °c. Soluble in ethanol and acetic acid, soluble in sodium hydroxide solution, insoluble in chloroform. UDCA is the isomer of CDCA, its litholytic effect is stronger than CDCA, no Diarrhea and liver toxicity. UDCA can reduce the absorption of cholesterol, and can reduce the synthesis of cholesterol and cholesterol content in bile. In addition, UDCA can also reduce concanavalin A binding fragment, which can promote the formation of bile crystals, thereby inhibiting the formation of stones. The combined use of UDCA and CDCA can enhance the litholytic effect of each alone, while reducing side effects. The combination of the two is mainly used for the treatment of gallbladder cholesterol stones. When the density of gallstones and bile or the CT Value of gallstones is less than 75 units, the dissolution rate of UDCA is the fastest. Patients with cholelithiasis after the use of this product, can increase the number of peripheral platelets. |
| Use | Suitable for the prevention and treatment of cholesterol gallstones |
