Summary
Velpatasvir is much less soluble at higher gastric pH. Pantoprazole can lower velpatasvir exposure and risk reduced antiviral efficacy.
What this interaction means in plain words
Pantoprazole and Sofosbuvir / velpatasvir can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
Why it happens
Increased gastric pH reduces velpatasvir solubility and absorption.
What to do
Avoid proton pump inhibitors where possible. If essential, give sofosbuvir/velpatasvir with food 4 hours before the PPI at the lowest dose, with close virologic monitoring.
