Hepatocyte membrane repair and protection agents: such as polyene phosphatidylcholine, polyunsaturated phosphatidylcholine, these drugs can regulate the energy metabolism of the liver, promote the regeneration of hepatocytes, reduce oxygen stress and lipid peroxidation, inhibit apoptosis of hepatocytes, prevention and treatment of liver fibrosis. Detoxification drugs: such as glutathione, N-acetyl cysteine, these drugs can improve the synthesis of the liver, detoxification, inactivation of hormones and so on. Antioxidant drugs: such as silymarin, bicyclic alcohol, these drugs have different degrees of protective and therapeutic effects on various types of liver injury caused by different poisons.
