Liver injury needs to choose appropriate oral treatment drugs according to the specific cause, such as antiviral drugs such as entecavir, interferon, glucocorticosteroids, liver-protecting drugs and so on. 1. Caused by hepatitis virus. If the liver injury is caused by hepatitis B and C viruses, the former patients can use oral drugs such as entecavir, and the latter can use drugs such as sofosbuvir. At the same time, it can also be supplemented with interferon drugs such as alpha interferon to regulate immune function and reduce viral replication. 2. Autoimmune diseases. If the liver injury is caused by autoimmune disease, the clinical use of methylprednisolone and other glucocorticosteroids and azathioprine and other immunosuppressants are often used to reduce the immune response. 3. Chronic liver injury. If the patient has chronic liver injury, and combined with clear hepatic fibrosis or cirrhosis, liver-protecting drugs such as compound glycyrrhizin tablets and reduced glutathione are often used as appropriate in the clinic. It is recommended that if there is any liver injury, consult a doctor in time and choose the most appropriate treatment plan according to the cause of the disease.
