Mechanism of action

Boceprevir directly inhibits the HCV NS3/4A serine protease, an enzyme essential for cleaving viral polyproteins into functional proteins required for viral replication. By blocking this protease, the drug prevents the maturation of viral proteins and halts HCV replication. It is used in combination with interferon-alpha and ribavirin for treatment of chronic hepatitis C.
