After passing through the blood-cerebrospinal fluid barrier, it is decomposed into glutamate and gamma-aminobutyric acid (GABA). Glutamate is involved in the information transmission of the central nervous system. Gamma-aminobutyric acid can antagonize the excitotoxic effects of glutamate, improve nerve cell metabolism, maintain nerve stress resistance, reduce the effect of blood ammonia, and improve brain function.

This product can inhibit the growth of many viruses such as respiratory syncytial virus, influenza virus, hepatitis A virus, adenovirus, etc. 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, damaging viral RNA and protein synthesis, and inhibiting viral replication and transmission. This product may also have an immune effect on respiratory syncytial virus and a neutralizing antibody effect.
