Treatment of chronic hepatitis C virus (HCV) infection in adults, including patients with or without cirrhosis. It is indicated for use in combination with other antiviral agents and is effective against multiple HCV genotypes.
Daclatasvir is a potent inhibitor of the HCV non-structural protein 5A (NS5A), which plays a critical role in viral RNA replication and virion assembly. By blocking this protein, it prevents the virus from multiplying and spreading.
Daclatasvir should not be used as monotherapy and must be combined with other antiviral medications. It requires a prescription and medical supervision. Patients should be monitored for potential drug interactions and should have liver function assessed during treatment. Effectiveness varies depending on HCV genotype and prior treatment history.
