Antiviral drug. It has an inhibitory effect on herpes simplex virus, varicella zoster virus, cytomegalovirus, etc. in vitro. After entering the cells infected by herpes virus, this product competes with deoxynucleoside for viral thymidine kinase or cell kinase, and the drug is phosphorylated into activated acyclovir triphosphate, and then inhibits viral replication in two ways: ① Interfering with viral DNA polymerase and inhibiting viral replication; ② Under the action of DNA polymerase, it binds to the growing DNA chain, causing the extension of the DNA chain to be interrupted. This product has a special affinity for viruses, but has low toxicity to mammalian host cells.

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. It inhibits the vomiting reflex by selectively blocking the presynaptic 5-HT3 receptors of peripheral neurons. It may also inhibit the stimulation of the vagus nerve in the rear region by directly blocking the central 5-HT3 receptors.

An important component of coenzymes required for sugar metabolism

Important coenzyme component required for tissue respiration

A cofactor for many enzymes, involved in the metabolism of amino acids and fats

Component of coenzymes I and II, essential for lipid metabolism and oxidation of tissue respiration

Component of coenzyme A, involved in the metabolism of sugar, fat and protein

This product participates in the ornithine cycle in the human body, promotes the formation of urea, and converts ammonia produced in the human body into non-toxic urea through the ornithine cycle and is excreted through urine, thereby reducing blood ammonia concentration. This product has a higher concentration of hydrogen ions, which helps to correct the acid-base balance during hepatic encephalopathy.
