Tác dụng
Mechanism of Action: Boceprevir is a selective hepatitis C virus (HCV) non-structural protein 3/4A (NS3/4A) protease inhibitor. It binds reversibly to the NS3 protease active site serine (Ser139) through α-ketoamide functional group to inhibit viral replication in HCV-infected host cells.
Absorption: Well absorbed from the GI tract. Food enhances absorption by up to 65%. Time to peak plasma concentration: 2 hr.
Distribution: Volume of distribution: Approx 772 L. Plasma protein binding: Approx 75%.
Metabolism: Undergoes hepatic metabolism via the aldo-ketoreductase (AKR)-mediated pathway to inactive metabolites; to a lesser extent, oxidative metabolism by CYP3A4 or CYP3A5.
Excretion: Mainly via faeces (79%) w/ less than 10% as unchanged drug. Mean elimination half-life: Approx 3.4 hr.
