Hepatitis C NS5A inhibitor
- Disrupts viral RNA replication and virion assembly
- Low resistance barrier → always combined with a second class for a durable cure
- Blocks hepatitis C viral assembly
- Cure rates above 95% in combination regimens
Drugs with this mechanism (6)
- Daclatasvir — Hepatitis C NS5A inhibitor used with sofosbuvir; strong enzyme inducers can undermine antiviral efficacy.
- Elbasvir — Hepatitis C NS5A inhibitor coformulated with grazoprevir; baseline resistance can affect regimen selection.
- Ledipasvir — Hepatitis C NS5A inhibitor (in Harvoni).
- Ombitasvir — Hepatitis C NS5A inhibitor.
- Pibrentasvir — Hepatitis C NS5A inhibitor.
- Velpatasvir — Pan-genotypic hepatitis C NS5A inhibitor (in Epclusa).
