Obeticholic acid is developed and produced by Intercept Pharmaceuticals in the United States It is the first drug approved by the U.S. FDA for the treatment of primary biliary cirrhosis (PBC) in the past two decades. The drug indirectly inhibits cytochrome 7A1 (CYP7A1), the key enzyme for bile acid synthesis, by activating the FXR receptor, thereby reducing the production of bile acid, improving cholestasis, and delaying disease progression. The specific indications for obeticholic acid are the treatment of primary biliary cholangitis, in combination with ursodeoxycholic acid (UDCA) in adults who have poor response to UDCA, or as a single agent in adults who cannot tolerate UDCA. Patients should always consult their doctor before taking any medication to make sure it is suitable for your condition.

For example, the generic obeticholic acid drug produced by Mylan in India is priced at more than 900 yuan, with a specification of 10 mg × 100 tablets.

If the patient's serum alkaline phosphatase (ALP) or total bilirubin levels do not decrease significantly after three months of treatment and the patient tolerates the drug well, the dose can be gradually adjusted to 10 mg per day. The maximum dose should not exceed 10 mg daily.

If patients experience severe side effects or cannot tolerate it, they should seek medical treatment promptly and consider discontinuing or changing medications.

At the same time, maintain good communication with the doctor and provide timely feedback on any discomfort or questions during the medication process.
