Interactions between your drugs

Moderate

fluticasone olutasidenib

Applies to: Advair Diskus (fluticasone / salmeterol) and olutasidenib

MONITOR: Coadministration with olutasidenib may decrease the plasma concentrations of drugs that are substrates of CYP450 3A4. Based on in vitro studies, olutasidenib may increase clearance via induction of CYP450 3A4, resulting in decreased plasma concentrations of agents that are metabolized by the isoenzyme. Clinical and pharmacokinetic data are currently lacking.

MANAGEMENT: Caution is advised if olutasidenib is used concomitantly with drugs that are substrates of CYP450 3A4, particularly sensitive substrates or those with a narrow therapeutic range. The prescribing information for olutasidenib recommends avoiding coadministration with CYP450 3A4 substrates for which minimal concentration changes may lead to therapeutic failure. If coadministration is required, clinical and laboratory monitoring may be appropriate whenever olutasidenib is added to or withdrawn from therapy. The prescribing information for concomitant medications should be consulted to assess the benefits versus risks of coadministration and for any dosage adjustments that may be required.

Minor

fluticasone salmeterol

Applies to: Advair Diskus (fluticasone / salmeterol) and Advair Diskus (fluticasone / salmeterol)

Although they are often combined in clinical practice, the concomitant use of beta-2 adrenergic agonists and corticosteroids may result in additive hypokalemic effects. Since beta-2 agonists can sometimes cause QT interval prolongation, the development of hypokalemia may potentiate the risk of ventricular arrhythmias including torsade de pointes. However, clinical data are limited, and the potential significance is unknown. Patients who are receiving systemic or nebulized formulations of beta-2 agonists, high dosages of inhaled beta-2 agonists, or systemic corticosteroid therapy may be at a greater risk of developing hypokalemia.

Drug and food interactions

Moderate

olutasidenib food

Applies to: olutasidenib

ADJUST DOSING INTERVAL: Coadministration with a high-fat meal may increase the plasma concentrations of olutasidenib. According to the product labeling, administration of a single 150 mg dose with a high-fat meal (approximately 800 to 1000 calories, with approximately 50% of those calories from fat) increased olutasidenib peak plasma concentration (Cmax) and systemic exposure (AUC) by 191% and 83%, respectively, in healthy subjects.

MANAGEMENT: Olutasidenib should be administered at about the same time each day, on an empty stomach at least 1 hour before or 2 hours after a meal.

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.
