Mechanism of action

Sofosbuvir is a nucleotide analog that inhibits the HCV NS5B RNA-dependent RNA polymerase, preventing viral RNA synthesis. Velpatasvir is an NS5A inhibitor that blocks a multifunctional viral protein essential for HCV replication and virion assembly. Together, this combination directly targets two critical steps in the HCV life cycle, achieving high cure rates across multiple HCV genotypes.
