Mechanism of action

ABT-450 directly inhibits the NS3/4A serine protease of hepatitis C virus, preventing the cleavage of viral polyproteins necessary for viral replication. Ritonavir, a CYP3A4 inhibitor, is co-administered as a pharmacokinetic booster to elevate and maintain therapeutic ABT-450 concentrations. This combination was developed as part of all-oral, interferon-free HCV treatment regimens.
