Dasabuvir is a non-nucleoside NS5B polymerase inhibitor used in combination with other antiviral agents for the treatment of chronic hepatitis C virus (HCV) infection, specifically genotypes 1a and 1b. It was approved as part of fixed-dose combination therapies (such as Viekira Pak) but is no longer widely marketed following advances in HCV therapies.
Pharmacokinetics
