描述
Alfosbuvir is a nucleotide prodrug that, once metabolized in cells, inhibits HCV NS5B RNA-dependent RNA polymerase—blocking viral replication across multiple genotypes. As China’s first domestic innovative HCV NS5B inhibitor with independent IP, it has shown promising efficacy in phase III trials—especially in combination with daclatasvir—for genotypes?1, 3, and 6, even among cirrhotic patients.

Alfosbuvir Tablets Mechanism of Action
Alfosbuvir is metabolized intracellularly into a non-natural nucleotide analogue that competes with natural nucleotides during viral RNA synthesis. This terminates RNA chain extension, effectively inhibiting HCV replication. It’s considered a pan-genotypic NS5B inhibitor with a high viral suppression profile.
