Mechanism of action

Peginterferon alfa-2a is a long-acting interferon that binds to type I interferon receptors, triggering innate immune responses including activation of natural killer cells and upregulation of antiviral genes. Ribavirin is a nucleoside analog that inhibits viral RNA-dependent RNA polymerase and reduces HCV replication. The combination provides synergistic antiviral activity against hepatitis C virus.
