Mechanism of action

Pegylated interferon alpha (Peg-IFN) is a long-acting form of interferon that activates innate and adaptive immune responses against hepatitis C virus (HCV). Ribavirin (RBV) is a nucleoside analog that inhibits viral RNA synthesis and enhances interferon-induced immune responses. The combination therapy works synergistically to reduce HCV viral load and achieve sustained virologic response.
