Mechanism of action

Sofosbuvir is a nucleotide analog that acts as a chain terminator of HCV RNA synthesis by inhibiting the NS5B polymerase. Daclatasvir is a non-structural protein 5A (NS5A) inhibitor that disrupts viral replication and assembly. Together, this combination directly targets two essential HCV enzymes, providing potent antiviral activity across multiple HCV genotypes.
