Drug Interaction Report

MONITOR: Coadministration with bempedoic acid may increase the plasma concentrations and the risk of adverse effects of drugs that are substrates of the uptake transporters organic anion transporting polypeptide (OATP) 1B1 and 1B3. The proposed mechanism, based on in vitro data, is decreased clearance due to bempedoic acid-mediated inhibition of OATP1B1 and 1B3.

MANAGEMENT: Caution is advised if bempedoic acid is used concomitantly with drugs that are substrates of OATP1B1 or 1B3, particularly those with a narrow therapeutic range. Dosage adjustments as well as clinical and laboratory monitoring should be considered whenever bempedoic acid is added to or withdrawn from therapy with these drugs. Patients should be monitored for the development of adverse effects.

ADJUST DOSING INTERVAL: Food enhances the oral bioavailability of glecaprevir and pibrentasvir. Relative to fasting conditions, mean glecaprevir systemic exposure (AUC) increased by 83% to 163% and mean pibrentasvir AUC increased by 40% to 53% when administered with moderate to high fat meals.

MANAGEMENT: Glecaprevir-pibrentasvir should be administered with food.
