Transaminases refer to alanine transaminase and glutamine transaminase. Western drugs for lowering aminotransferases mainly include biphenyl dibenzoate, silymarin, bicyclic alcohol, diammonium glycyrrhizinate and so on. 1. Biphenyldiphenyl ester: Biphenyldiphenyl ester can enhance the liver detoxification function, reduce the pathological damage of the liver, promote the regeneration of hepatocytes and protect the hepatocytes, so as to improve the liver function, mainly for the treatment of prolonged hepatitis and long-term single alanine aminotransferase abnormality, individual patients may appear nausea after taking the drug. 2. Silymarin: Silymarin has the effect of protecting and stabilizing liver cell membrane. It is suitable for the treatment of chronic prolonged hepatitis, chronic active hepatitis, early cirrhosis, toxic liver injury and other diseases. Side effects mainly include dizziness, nausea and eructation. 3. Dicyclanol: Dicyclanol has anti-hepatitis B virus activity and is suitable for the elevation of aminotransferase caused by chronic hepatitis. Dicyclanol has fewer adverse effects, only a few patients may experience dizziness, generally can be tolerated. 4. Diammonium glycyrrhizinate: it has strong anti-inflammatory, hepatocyte membrane protection and liver function improvement effects, mainly used in the adjuvant treatment of acute and chronic viral hepatitis accompanied by elevated gammaglutamyltransferase. Its side effects include nausea, vomiting, dry mouth, dizziness and urticaria. No matter which condition causes the elevation of aminotransferase, it is necessary to use medication with prescription after detailed examination and comprehensive judgment by doctor to avoid aggravating the condition by blindly taking medication on your own.
