Grazoprevir is an oral inhibitor of the hepatitis C virus (HCV) NS3/4A protease, approved for use in combination with elbasvir for the treatment of chronic HCV genotype 1 and 4 infections in adults. It is used as part of direct-acting antiviral regimens and is currently approved and used in clinical practice.
