Ombitasvir, paritaprevir, and ritonavir is a fixed-dose combination antiviral medication used in the treatment of chronic hepatitis C virus (HCV) infection. Ombitasvir is an NS5A inhibitor, paritaprevir is an NS3/4A protease inhibitor, and ritonavir acts as a pharmacokinetic enhancer by inhibiting CYP3A-mediated metabolism of paritaprevir. This combination is approved for use in many countries and was commonly marketed as part of the Viekira Pak regimen.
Pharmacokinetics
Pharmacokinetic parameters in healthy adult volunteers after oral administration of the co-formulated combination under fed conditions.
