Generic NameSofosbuvir + Velpatasvir
Therapeutic ClassDirect-acting antiviral (DAA) combination

Indications ▼
Chronic hepatitis C virus (HCV) infection, genotypes 1–6
Used in adults and adolescents ≥12 years in combination therapy
Effective in patients with or without compensated cirrhosis
Mechanism & Pharmacokinetics ▼
Mechanism: Sofosbuvir: NS5B RNA polymerase inhibitor causing chain termination; Velpatasvir: NS5A inhibitor preventing viral replication and assembly. Combination halts HCV replication.
Pharmacokinetics: Rapid oral absorption; Sofosbuvir metabolized to active triphosphate (half-life ~27h); Velpatasvir reaches peak plasma ~3h; mainly excreted in feces. Co-administration enhances sustained virologic response (SVR).
Dosage & Administration ▼
Dosage must follow physician guidance, adjusted by genotype, liver function, and treatment history.
| Indication / Patient Group | Dose | Frequency / Notes |
|---|---|---|
| Chronic HCV (all genotypes, without cirrhosis) | 400 mg Sofosbuvir + 100 mg Velpatasvir | Once daily for 12 weeks |
| Chronic HCV with compensated cirrhosis | 400 mg Sofosbuvir + 100 mg Velpatasvir | Once daily for 12 weeks (may vary in special populations) |
