Mechanism of action

Pegylated interferon alpha (Peg-IFN) is a long-acting form of interferon that activates innate and adaptive immune responses against HCV. Ribavirin (RBV) is a nucleoside analog that inhibits viral replication and enhances interferon-induced antiviral effects. The 48-week combination regimen was the standard of care for chronic hepatitis C, particularly for genotype 1 infection, before direct-acting antivirals became available.
