Summary

Ribavirin (ICN-1229) is an antiviral agent against a broad spectrum of viruses including HCV , HIVl , and RSV . Ribavirin also has anti- orthopoxvirus and anti-variola activities.


In Vitro

Treatment of LPS-stimulated microglia with 5, 10 and 20 μM Ribavirin (ICN-1229) induces reduction of NO 2 levels for 43% (p<0.05), 53% (p<0.05) and 59% (p<0.05), respectively. Ribavirin (ICN-1229) (10 mM) insignificantly decreases the cell surface area in non-stimulated culture, but significantly reduces cell surface area (by 32%, p<0.05) in LPS-stimulated microglia [3] . Ribavirin (ICN-1229) is active against DENV, with an EC 50 of 3 μM in A549 cells, and combination of CM-10-18 with Ribavirin (ICN-1229) demonstrates a clear enhancement in the reduction of virus replication [4] .

MCE has not independently confirmed the accuracy of these methods. They are for reference only.


In Vivo

ALT, AST activities and bilirubin levels are significantly loared by administration of JAT in combination with interferon and Ribavirin (ICN-1229) (p<0.01). JAT, interferon or ribavirin alone with CCl 4 , livers appear to exhibit some liver protection against CCl 4 as evident by the presence of normal hepatic cords, absence of necrosis and lesser fatty infiltration. Groups treated with JAT, Peg-interferon and Ribavirin (ICN-1229) separately or in combination shows reduction in the expression of TGF- β and Bax. In the group treated by triple combination of interferon, Ribavirin (ICN-1229), and JAT, the expression level of p53 is markedly reduced [1] . Ribavirin (ICN-1229) capsules (400 mg of ribavirin)-treated Wistar rats show a significant decrease in activin-A and significant increase in follistatin at the serum and liver levels. Ribavirin (ICN-1229) has strong antiviral activity only when ribavirin is combined with either IFN-α or Peg-IFN-α [2] . Ribavirin (40 mg/kg, p.o.) significantly improves the antiviral efficacy of CM-10-18 in mice. Ribavirin (ICN-1229) inhibits DENV virus infection in cultured cells, but it is ineffective in reducing viremia in monotherapy [4] .
