Elbasvir and grazoprevir is a fixed-dose combination of two direct-acting antiviral agents used for the treatment of chronic hepatitis C virus (HCV) infection. Elbasvir is an HCV NS5A inhibitor and grazoprevir is an HCV NS3/4A protease inhibitor. This combination is approved and in current clinical use for adults with genotype 1 or 4 HCV infection.
Pharmacokinetics
Pharmacokinetics in healthy adult subjects after a single tablet containing elbasvir 50 mg and grazoprevir 100 mg administered orally.
