Interactions between your drugs

Moderate

olmesartan resmetirom

Applies to: olmesartan and resmetirom

MONITOR: Coadministration with resmetirom may increase the plasma concentrations and effects of drugs that are substrates of hepatic uptake transporters organic anion transporting polypeptides (OATP) 1B1, OATP 1B3, and/or the intestinal and hepatobiliary efflux transporter breast cancer resistance protein (BCRP). Resmetirom is both a substrate and an inhibitor of these transporters. Clinical studies exist for resmetirom with OATP1B1 and OATP1B3 substrates, simvastatin, and pravastatin; as well as with rosuvastatin and atorvastatin which are BCRP, OATP1B1 and OATP1B3 substrates. Resmetirom was shown to increase the systemic exposure (AUC) of simvastatin, pravastatin, rosuvastatin, and atorvastatin by 1.7-fold, 1.4-fold, 1.8-fold, and 1.4-fold, respectively. Clinical data are not available for other OATP 1B1, OATP 1B3 and/or BCRP substrates.

MANAGEMENT: Caution and closer monitoring may be advised if resmetirom is coadministered with drugs that are substrates of the OATP 1B1, OATP 1B3, and/or BCRP transporters. Dosage adjustments as well as clinical and laboratory monitoring for the development of adverse effects may be appropriate for some drugs whenever resmetirom is added to or withdrawn from therapy. Individual product labeling should be consulted for further guidance.

Drug and food interactions

Moderate

olmesartan food

Applies to: olmesartan

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.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
