This product is a brain metabolism improving drug, which is a cyclic derivative of g-aminobutyric acid. It has the effect of resisting brain function damage caused by physical and chemical factors. It can promote ATP in the brain, promote acetylcholine synthesis and positively enhance the conduction of nerve excitement, and has the effect of promoting brain metabolism. It can resist brain function damage caused by physical and chemical factors. It has an improving effect on retrograde amnesia caused by hypoxia. It can enhance memory and improve learning ability.

Broad-spectrum antiviral drug. It has the effect of inhibiting the growth of multiple viruses such as respiratory syncytial virus, influenza virus, hepatitis A virus, adenovirus, etc. in vitro, and its mechanism is not fully understood. After entering the virus-infected cells, the drug is rapidly phosphorylated, and its product acts as a competitive inhibitor of viral synthase, inhibiting inosine monophosphate dehydrogenase, influenza virus RNA polymerase and mRNA guanosine transferase, thereby causing a decrease in intracellular guanosine triphosphate, impairing viral RNA and protein synthesis, and inhibiting viral replication and transmission. It may also have an immune effect and neutralizing antibody effect on respiratory syncytial virus.

It has a strong antitussive effect, and has antihistamine, smooth muscle spasm relief, anti-inflammatory and local anesthetic effects. The antitussive effect usually appears 30-60 minutes after taking the medicine, and the effect lasts for 4-6 hours or longer.

This product is a non-narcotic antitussive drug that mainly blocks the incoming sensory nerve impulses of the lung and pleural receptors, and also directly inhibits the antitussive center. It also has a papaverine-like smooth muscle spasmolytic effect
