[In vitro efficacy of ingavirin against the Mexican pandemic subtype H1N1 of influenza A virus, strains A/California/04/2009 and A/California/07/2009].

Ingavirin was shown to be efficient in inhibition of the influenza virus strains A/California/04/2009 and A/California/07/2009 (H1N1) in the MDCK cell culture. The coefficient of the cytopathic activity inhibition amounted to 50 and 60%, and the inhibition coefficients of the specific hemagglutinin formation were 50 and 50%, and 79,1 and 75% before and after the enrichment in chick embryos respectively.
