Mechanism of action

Direct-acting antivirals (DAAs) target specific viral proteins such as proteases, polymerases, or other essential enzymes needed for the viral life cycle. By binding to and inhibiting these molecular targets, DAAs block viral replication at a specific step, reducing viral load. This class has been most extensively developed and clinically validated for hepatitis C virus (HCV) and more recently for SARS-CoV-2 and other viral infections.
