Summary

Ledipasvir dissolves poorly at higher pH, so acid suppression can reduce its absorption and risk reduced hepatitis C cure rates. The effect is dose and timing dependent.

What this interaction means in plain words

Lansoprazole and Ledipasvir / sofosbuvir can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.

Evidence level: High

Why it happens

Raised gastric pH decreases ledipasvir solubility and absorption.

What to do

Give the PPI simultaneously with ledipasvir/sofosbuvir under fasted conditions at a dose no higher than omeprazole 20 mg equivalent. Avoid higher PPI doses where possible.
