Antiviral drug for external use
Pharmic action:
Devirs is an antiviral drug.
Ribavirin triphosphate (RTF) is a potent inhibitor of inosine monophosphate dehydrogenase (IMP dehydrogenase), viral RNA polymerase and viral mRNA guanylyltransferase. Inhibition of the latter stops mRNA capping, resulting in significant depletion of intracellular guanosine triphosphate stores and inhibition of viral RNA and protein synthesis. Ribavirin also integrates into the viral genome, causing lethal mutations, with a subsequent reduction in the pathogenicity of the virus.
Ribavirin inhibits replication of new virions, which ensures reduction of viral load, selectively inhibits viral RNA synthesis without suppressing RNA synthesis in normally functioning cells.
The most sensitive DNA viruses to ribavirin are herpes simplex virus, adenoviruses, CMV, smallpox group viruses, Marek’s disease; RNA viruses – influenza A, B, paramyxoviruses (parainfluenza, mumps, Newcastle disease), reoviruses, arenaviruses (Lassa fever virus, Bolivian hemorrhagic fever virus), bunyaviruses (Rift Valley fever virus, Crimean-Congo hemorrhagic fever virus), hantaviruses (hemorrhagic fever virus with renal or pulmonary syndrome), oncogenic RNA viruses.
Ribavirin-insensitive DNA viruses: Varicella zoster, pseudorabies virus, natural cowpox; RNA viruses: enteroviruses, rhinoviruses, Semliki forest encephalitis virus.
Pharmacokinetics:
When applied to the skin and topically, systemic absorption is minimal and virtually insignificant.
