Triviron — new innovative antiviral drug. The mechanism of action is based on the destruction of the RNA virus particles using a low-molecular-weight artificial ribonuclease (artificial ribonucleases). The nature of the catalytic action of the drug is one of important points. I.e. Triviron® operates repeatedly: one molecule of active ingredient destroys many RNA molecules. As a result, the drug may be used at low doses which makes its application economically feasible in industrial poultry and pig production.
