Interactions between your drugs

Moderate

nebivolol oritavancin

Applies to: nebivolol / valsartan and oritavancin

MONITOR: Coadministration with oritavancin may decrease the plasma concentrations and therapeutic effects drugs that are substrates of CYP450 3A4 and/or 2D6. The proposed mechanism is increased clearance due to oritavancin-mediated induction of these isoenzymes. In a screening drug interaction study in 16 healthy volunteers, a single 1,200 mg dose of oritavancin decreased midazolam systemic exposure (AUC) by 18% and the urinary dextromethorphan-to-dextrorphan ratio by 31%, indicating weak induction of CYP450 3A4 and 2D6, respectively.

MANAGEMENT: Caution is advised when oritavancin used concomitantly with drugs that are substrates of CYP450 3A4 and/or 2D6, particularly sensitive substrates or those for which minimal concentration changes may lead to therapeutic failure. Dosage adjustments as well as clinical and laboratory monitoring may be appropriate for some drugs whenever oritavancin is added to or withdrawn from therapy. Individual product labeling for the CYP450 3A4 and/or 2D6 substrate(s) should be consulted for further guidance.

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.
