Affected OrganismHepatitis C virus, RSV and other RNA/DNA viruses
IndicationFor the treatment of chronic hepatitis C and for respiratory syncytial virus (RSV).
PharmacologyRibavirin is an anti-viral drug active against a number of DNA and RNA viruses. It is a member of the nucleoside antimetabolite drugs that interfere with duplication of the viral genetic material. The drug inhibits the activity of the enzyme RNA dependent RNA polymerase, due to it's resemblence to building blocks of the RNA molecules. The oral form is used in the treatment of hepatitis C, in combination with interferon drugs. The aerosol form is used to treat respiratory syncytial virus-related diseases in children. The primary serious adverse effect of ribavirin is hemolytic anemia, which may worsen preexisting cardiac disease.
Mechanism of actionRibavirin is readily phosphorylated intracellularly by adenosine kinase to ribavirin mono-, di-, and triphosphate metabolites. Ribavirin triphosphate (RTP) is a potent competitive inhibitor of inosine monophosphate (IMP) dehydrogenase, viral RNA polymerase and messenger RNA (mRNA) guanylyltransferase (viral) and can be incorporated into RNA in RNA viral species.. Guanylyltranserase inhibition stops the capping of mRNA. These diverse effects result in a marked reduction of intracellular guanosine triphosphate (GTP) pools and inhibition of viral RNA and protein synthesis. Ribavirin is also incorporated into the viral genome causing lethal mutagenesis and a subsequent decrease in specific viral infectivity.
