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 forms a protective layer in the intestine to prevent the invasion of pathogens and viruses; stimulates the intestine to secrete antibodies and improves intestinal immunity; selectively kills intestinal pathogens, protects and promotes the growth of beneficial bacteria; regulates the electrolyte and water balance of the intestinal mucosa; promotes the secretion of gastric juice and enhances digestive function.

This product is a non-narcotic antitussive drug that mainly blocks the afferent 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.

This product is a new type of non-narcotic analgesic, with mild antipyretic and muscle relaxant effects. It is effective for moderate and severe pain. An intramuscular injection of 20 mg of this product is equivalent to the effect of 12 mg of morphine. It has a mild respiratory depressant effect. It has no depressant effect on the circulatory system. There is no tolerance and dependence.

It is converted into flavine mononucleotide (FMN) and flavin adenine dinucleotide, both of which are important coenzymes for tissue respiration, and can activate vitamin B6, convert characteristic amino acids into niacin, and may be related to maintaining the integrity of red blood cells.
