Ribavirin Injection

1 Pharmacology Broad-spectrum antiviral drug. It has the effect of inhibiting the growth of many viruses such as respiratory syncytial virus, influenza virus, hepatitis A virus, adenovirus, etc. in vitro, and its mechanism is not fully understood. This product does not change the adsorption, invasion and uncoating of viruses, nor does it induce the production of interferon. 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. 2 Toxicological animal experiments have found that this product can induce benign tumors of the breast, pancreas, pituitary and adrenal glands, but its carcinogenicity to humans has not been confirmed. The drug can cause malformations of the head, palate, eyes, jaw, bones and gastrointestinal tract in animals such as hamsters, and reduce the survival of offspring, but primate experiments have not found any effect of the drug on the fetus. Cardiac damage occurred in mice, rats, and monkeys given oral ribavirin at doses of 30, 36, and 120 mg/kg or more for 4 weeks (equivalent to human doses of 4.8, 12.3, and 111.4 mg/kg for a 5 kg child or 2.5, 5.1, and 40 mg/kg for a 60 kg adult).

The main ingredient of this product is ribavirin, whose chemical name is 1-beta;-D-ribofuranosyl-1H-1,2,4-triazole-3-carboxamide.
