Dasabuvir, ombitasvir, paritaprevir, and ritonavir is a fixed-dose combination regimen used as antiviral therapy for chronic hepatitis C virus (HCV) infection. Paritaprevir (an NS3/4A protease inhibitor) is boosted with ritonavir (a CYP3A inhibitor), ombitasvir is an NS5A inhibitor, and dasabuvir is a non-nucleoside NS5B polymerase inhibitor. This fixed combination (also marketed as Viekira Pak) is approved for the treatment of HCV genotype 1 and was widely used but has been largely superseded by newer regimens.
Pharmacokinetics
Pharmacokinetic parameters for healthy adult subjects after oral administration (fed state). Parameters are predominantly derived from population PK and single/multiple dose studies.
