Interactions between your drugs

Moderate

valsartan nebivolol

Applies to: nebivolol / valsartan and nebivolol / valsartan

GENERALLY AVOID: In the Valsartan Heart Failure Trial, the combination of valsartan with a beta-blocker and an ACE inhibitor was associated with unfavorable outcomes on morbidity and mortality in heart failure patients. The mechanism is unknown.

MANAGEMENT: The manufacturer recommends that the triple combination of valsartan with a beta-blocker and an ACE inhibitor be avoided in heart failure patients.

Moderate

nebivolol rolapitant

Applies to: nebivolol / valsartan and Varubi IV (rolapitant)

MONITOR: Coadministration with rolapitant may increase the plasma concentrations of drugs that are substrates of the CYP450 2D6 isoenzyme. Rolapitant is a moderate CYP450 2D6 inhibitor, with inhibitory effect lasting at least 7 days after a single dose. When a 30 mg dose of dextromethorphan, a CYP450 2D6 probe substrate, was administered with a 180 mg dose of rolapitant on day 1 of a pharmacokinetic study, dextromethorphan peak plasma concentration (Cmax) and systemic exposure (AUC) increased by 120% and 160%, respectively. When dextromethorphan was administered on day 8 without rolapitant, Cmax and AUC increased by 180% and 230%, respectively. The duration of CYP450 2D6 inhibition was not studied beyond 7 days and may last longer.

MANAGEMENT: Caution is advised when rolapitant is prescribed with drugs that are significantly metabolized by CYP450 2D6, particularly those with a narrow therapeutic range. Dosage adjustments as well as clinical and laboratory monitoring may be appropriate for some drugs whenever rolapitant is added to or withdrawn from therapy. Due to the prolonged duration of CYP450 2D6 inhibition by rolapitant, prolonged monitoring for adverse effects of drugs that are substrates of CYP450 2D6 may be required for at least 28 days after administration of rolapitant.

Drug and food interactions

Moderate

valsartan food

Applies to: nebivolol / 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.
