Cellular immunomodulatory drugs have the function of inducing T cell differentiation, promoting the development, maturation and activation of T lymphocyte subsets, and can regulate the proportion of each lymphocyte subset to make it tend to normal.

This product is a formylated derivative of the reduced form of folic acid, and is the activated form of folic acid in the body. The function of folic acid antagonists such as methotrexate is to bind to dihydrofolate reductase and block the conversion of folic acid to tetrahydrofolate. This product can directly provide the activated form of folic acid in the body, which can rescue the toxic reaction of excessive folic acid antagonists in the body, and is beneficial to the synthesis of thymine nucleotides, DNA, RNA and even proteins. This product can limit the degree of damage of methotrexate to normal cells, and through mutual competition, it can reverse the reaction of methotrexate to bone marrow and gastrointestinal mucosa, but it has no effect on the existing methotrexate neurotoxicity.

It has the effect of resisting platelet aggregation and disaggregating aggregated platelets. In addition, it can dilate arterioles, improve microcirculation and increase cerebral blood flow, thus producing the effects of anti-thrombosis and thrombolysis.

This product is a highly selective 5-HT3 receptor antagonist, which has a good preventive and therapeutic effect on nausea and vomiting caused by radiotherapy, chemotherapy and surgery. It inhibits the occurrence of nausea and vomiting by antagonizing the 5-HT3 receptors in the central chemoreceptor area and peripheral vagus nerve endings. This product has high selectivity and no side effects such as extrapyramidal reactions and excessive sedation.

This drug is an immune enhancement drug. It is a polynucleotide peptide (molecular weight less than 5000) extracted from healthy human blood or animal spleen. It is not easily destroyed by RNAse, DNAse and trypsin. This drug is an important factor in cellular immune response. It has no antigenicity and is not an antibody fragment, but it can transmit the cellular immune reactivity of multiple antigens, including bacteria, fungi, viruses, tissue compatibility antigens and tumor-specific antigens, etc. It can enhance the immune reactivity of receptor cells, promote the chemotaxis of macrophages, increase delayed cell response, and improve the body's ability to kill tumors.
