Mechanism of action

Pegylated interferon alpha-2a is a long-acting form of interferon that binds to interferon-alpha receptors on immune cells, triggering antiviral and immunomodulatory effects including upregulation of MHC molecules and activation of natural killer cells. Ribavirin is a nucleoside analog that inhibits viral RNA-dependent RNA polymerase and depletes guanosine pools, reducing hepatitis C virus replication. The combination provides synergistic antiviral activity.
