Edit list (add/remove drugs)

Interactions between your drugs

Moderate

somatrem olutasidenib

Applies to: Protropin (somatrem) and olutasidenib

MONITOR: Coadministration with inducers of CYP450 3A4 may decrease the plasma concentrations of olutasidenib, which is primarily metabolized by the isoenzyme. When coadministered with rifampin, a potent CYP450 3A4 inducer, olutasidenib peak plasma concentration (Cmax) and systemic exposure (AUC) decreased by 43% and 80%, respectively. No data are available for other, less potent CYP450 3A4 inducers.

MANAGEMENT: The potential for diminished pharmacologic effects of olutasidenib should be considered during coadministration with CYP450 3A4 inducers. Alternative treatments may be required if an interaction is suspected.

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.
