It is converted into terbutaline in the body, which is an adrenaline beta 2 receptor agonist, relaxes bronchial smooth muscles, and achieves an antiasthmatic effect.

It can catalyze the cleavage of peptide bonds in protein molecules, decompose proteins, peptides, lipids, amides and other substances, and has anti-inflammatory and anti-edema effects.

Transfer factors can transfer certain specific and nonspecific cellular immune functions of the donor to the recipient, thereby expanding the recipient's immune response.

Transfer factors can trigger and regulate cellular immune function, sensitizing cells that have not been exposed to antigens, causing T lymphocytes to differentiate and proliferate into effector T cells, generating a synergistic reaction, turning into sensitized lymphocytes and releasing lymphokines with immune activity to attack foreign substances such as viruses in the body.

Activate macrophages and enhance the ability of macrophages that participate in immune responses to recognize, bind, phagocytize and digest antigens.

Transfer factor can also increase the production of various cytokines in the body, such as interleukin II and interferon, adjust multiple immune indicators, act on multiple links of the immune system, correct the body's immune imbalance, and adjust low or hyperactive immune function.

This product is a potent and highly selective competitive antagonist of 5-hydroxytryptamine 3 (5-HT3) receptors in peripheral neurons and the central nervous system. Certain substances, including some chemotherapy drugs, can stimulate chromaffin cells in the visceral mucosa to release 5-hydroxytryptamine, thereby inducing vomiting reflexes accompanied by nausea. This product mainly inhibits the vomiting reflex by selectively blocking the presynaptic 5-HT3 receptors of peripheral neurons. In addition, its antiemetic effect may also be related to its inhibition of the stimulation of the vagus nerve in the rear region by directly blocking the central 5-HT3 receptors.

This product is a vitamin drug. It has the function of promoting growth and maintaining the normal functions of epithelial tissues such as skin, conjunctiva, cornea, etc., and participates in the synthesis of rhodopsin, enhancing the photosensitivity of the retina; it participates in many oxidation processes in the body, especially the oxidation of unsaturated fatty acids. When vitamin A is deficient, growth stops, bones grow poorly, reproductive function declines, skin becomes rough and dry, cornea softens, and dry eye and night blindness occur.
