Moderate

sodium bicarbonate velpatasvir

Applies to: sodium bicarbonate, sofosbuvir / velpatasvir

ADJUST DOSING INTERVAL: Concurrent administration of velpatasvir with drugs that elevate gastric pH such as antacids may reduce its gastrointestinal absorption. Velpatasvir exhibits pH-dependent solubility, with increased solubility at lower pH. Drugs that increase gastric pH are expected to decrease the plasma concentration of velpatasvir.

MANAGEMENT: If an antacid is required, the antacid should be taken 4 hours before or 4 hours after administration of sofosbuvir-velpatasvir. The same precaution may be applicable to other drugs with antacid effects.
