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 α, γ 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.

Palonosetron is a selective antagonist of the 5-HT3 receptor with strong affinity, and has no affinity or low affinity for other receptors. The 5-HT3 receptor is located in the central and peripheral vagus nerve endings of the emetic chemotherapy receptor area in the medulla oblongata. Chemotherapy drugs stimulate the release of 5-HT by chromaffin cells in the small intestine, and 5-HT then activates the 5-HT3 receptors of the vagal afferent nerves, producing a vomiting reflex.

It accelerates the development of the chicken brain, is beneficial to the protein synthesis of nerve cells and their respiratory chain, stimulates the production of related hormones, protects the central nervous system from toxic substances, improves the rat's ability to resist hypoxia, accelerates brain maturation, enhances recognition ability, and speeds up the rotation of glucose in the blood-brain barrier

Inhibits the secretion of growth hormone, thyroid stimulating hormone, insulin and glucagon, and inhibits the secretion of gastric acid; affects the absorption, motility, visceral blood flow and nutritional function of the gastrointestinal tract; inhibits the secretion of gastrin, gastric acid and pepsin, and treats upper gastrointestinal bleeding; reduces the blood flow to the visceral organs without significantly changing the systemic arterial blood pressure, and is used to treat esophageal varicose bleeding; reduces the endocrine secretion of the pancreas.
