Interactions between your drugs

Moderate

valsartan enasidenib

Applies to: valsartan and enasidenib

MONITOR: Based on in vitro data, coadministration with enasidenib may increase the plasma concentrations of drugs that are substrates of the transporters, organic anion transporting polypeptides (OATP) 1B1/1B3 and breast cancer resistance protein (BCRP). The proposed mechanism is decreased clearance due to enasidenib -mediated inhibition of OATP1B1/1B3 and BCRP transporters. There are no clinical data regarding the use of enasidenib with these substrates.

MANAGEMENT: Caution is advised when enasidenib is used concurrently with medications that are substrates of OATP 1B1/1B3 and/or BCRP, particularly those with a narrow therapeutic range. Dosage adjustments as well as clinical and laboratory monitoring may be appropriate for some drugs whenever enasidenib is added to or withdrawn from therapy.

Drug and food interactions

Moderate

valsartan food

Applies to: valsartan

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.
