Antiviral drug. It has an inhibitory effect on herpes simplex virus, varicella zoster virus, cytomegalovirus, etc. in vitro. After entering the cells infected by herpes virus, this product competes with deoxynucleoside for viral thymidine kinase or cell kinase, and the drug is phosphorylated into activated acyclovir triphosphate, and then inhibits viral replication in two ways: ① Interfering with viral DNA polymerase and inhibiting viral replication; ② Under the action of DNA polymerase, it binds to the growing DNA chain, causing the extension of the DNA chain to be interrupted. This product has a special affinity for viruses, but has low toxicity to mammalian host cells.

It has certain anti-inflammatory, liver cell membrane protection and liver function improvement effects. Pharmacological experiments have shown that oral administration of mice can reduce the increase of serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) caused by carbon tetrachloride, thioacetamide and D-aminogalactic acid. It can also significantly reduce the damage of D-aminogalactic acid to the liver and improve the chronic damage of immune factors to the liver.

Extract from the above information

This product is an immunomodulatory drug. It has the function of regulating and enhancing the cellular immune function of the human body. It can promote the maturation of T lymphocytes in peripheral blood after mitogen activation, increase the secretion of various lymphokines (such as alpha;, gamma; interferon, interleukin 2 and interleukin 3) after T cells are activated by various antigens or mitogens, and increase the level of lymphokine receptors on T cells. It also enhances lymphocyte response by activating T4 helper cells. In addition, this product may affect the chemotaxis of NK precursor cells, which become more cytotoxic after exposure to interferon. Therefore, this product has the function of regulating and enhancing the cellular immune function of the human body. This product is an immune bidirectional modulator. It has the function of inducing and promoting the differentiation, maturation and activation of T lymphocytes and their subsets, and regulating T lymphocytes.
