Elbasvir is an oral, direct-acting antiviral drug that acts as an inhibitor of the hepatitis C virus (HCV) NS5A protein, which is essential for viral replication. It is approved for use in combination with grazoprevir in the treatment of chronic HCV infection in adults. Elbasvir is currently used in clinical practice.
