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adjustments as well as clinical and laboratory monitoring should be considered whenever bempedoic acid is added to or withdrawn from therapy with these drugs.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.

GENERALLY AVOID: Moderate-to-high dietary intake of potassium, especially salt substitutes, may increase the risk of hyperkalemia in some patients who are using angiotensin II receptor blockers (ARBs). ARBs can promote hyperkalemia through inhibition of angiotensin II-induced aldosterone secretion. Patients with diabetes, heart failure, dehydration, or renal insufficiency have a greater risk of developing hyperkalemia.

MANAGEMENT: Patients should receive dietary counseling and be advised to not use potassium-containing salt substitutes or over-the-counter potassium supplements without consulting their physician. If salt substitutes are used concurrently, regular monitoring of serum potassium levels is recommended. Patients should also be advised to seek medical attention if they experience symptoms of hyperkalemia such as weakness, irregular heartbeat, confusion, tingling of the extremities, or feelings of heaviness in the legs.
