Potentiation of the antiviral activity of human interferons by virazole in in vitro experiments

Combination of interferon and virazole results in potentiation of their antiviral activity. This was demonstrated with all three types of natural interferons and the recombinant RL-2-interferon. This effect is retained at a temperature of 37 degrees C and increases when the chemical drug is combined with a mixture of alpha- and gamma-interferon.
