A broad-spectrum antiviral drug that inhibits the growth of multiple viruses in vitro, including respiratory syncytial virus, influenza virus, hepatitis A virus, and adenovirus. 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 reduction 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.

This product is a calcium channel blocker. It can prevent cell damage caused by pathological calcium overload in cells due to ischemia and other reasons; 1. It can relieve vasospasm and has a lasting inhibitory effect on persistent vasospasm caused by vasoconstrictor substances, especially on the basilar artery and internal carotid artery; 2. It has vestibular inhibitory effect, which can increase the blood flow of cochlear arterioles and improve the circulation of vestibular organs; 3. It has anti-epileptic effect, which can block the pathological calcium overload of nerve cells and prevent paroxysmal depolarization and cell discharge, thereby avoiding epileptic seizures; 4. It can protect the myocardium and significantly reduce ischemic myocardial damage; 5. It can also improve renal function and can be used for chronic renal failure; in addition, this product also has anti-histamine effect.

This product belongs to the benzamide antipsychotic drug, which has an inhibitory effect on the hyperfunction of dopaminergic nerves in the midbrain limbic system and an antagonistic effect on dopaminergic nerve movement disorders in the striatum, thereby producing a calming and sedative effect. It is characterized by its good effect on sensory and motor neurological diseases and psychomotor behavioral disorders. Animal experiments have confirmed that this product can block the conduction of pain impulses through the spinal thalamic tract to the reticular formation. The analgesic effect of this drug may be related to the integration of pain impulses by the thalamus. In addition, it has an antiemetic effect.
