Mechanism of action

Pegylated interferon alpha (Peg-IFN) is a long-acting form of interferon that activates innate and adaptive immune responses against HCV, while ribavirin (RBV) is a nucleoside analog that inhibits viral RNA synthesis and enhances interferon-mediated antiviral effects. The combination therapy works synergistically to reduce viral load and achieve sustained virological response in hepatitis C patients.
