Immune bidirectional regulatory drug. It has the function of inducing and promoting the differentiation, maturation and activation of T lymphocytes and their subgroups, regulating the ratio of T lymphocytes to make CD4/CD8 tend to normal; regulating and enhancing the function of human cellular immune function, 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 or 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 T helper cells. In addition, this product may affect the chemotaxis of NK precursor cells, which become more cytotoxic after exposure to interferon, which is conducive to its therapeutic effect. In addition, this product can enhance the body's ability to resist radiation. Therefore, this product has the function of regulating and enhancing the cellular immune function of the human body.

This product is a H2 receptor antagonist of the guanyl thiazole class, which has the characteristics of high affinity for H2 receptors, and has a significant inhibitory effect on gastric acid secretion, and has an inhibitory effect on basal secretion and the increase of gastric acid and pepsin caused by various stimuli. This product does not change the gastric emptying rate, does not interfere with pancreatic function, and has no adverse effects on the cardiovascular system and kidney function. This product is different from cimetidine, but it is similar to ranitidine, that is, long-term high-dose treatment does not cause androgen antagonism side effects such as male breast development, impotence, lack of libido, and female breast pain and galactorrhea, etc. It has no teratogenic, carcinogenic, drug enzyme inhibitory and androgen inhibitory effects.

Erythropoietin is an active glycoprotein secreted by the kidneys. It acts on erythroid hematopoietic progenitor cells in the bone marrow and promotes their proliferation and differentiation. This product can induce a significant effect of stimulating colony formation through late-stage mother erythroid progenitor cells (CFUE). At high concentrations, this product can also stimulate early-stage mother erythroid progenitor cells (BFUE) to induce colony formation.
