Interactions between your drugs

Moderate

armodafinil belumosudil

Applies to: armodafinil and belumosudil

MONITOR: Coadministration with inducers of CYP450 3A4 may decrease exposure to belumosudil, which is primarily metabolized by the isoenzyme. Concomitant use with the moderate CYP450 3A4 inducer, efavirenz, is predicted to decrease belumosudil peak plasma concentration (Cmax) and systemic exposure (AUC) by 32% and 35%, respectively, in healthy subjects. The interaction has not been studied with other, less potent inducers.

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

Drug and food interactions

Moderate

belumosudil food

Applies to: belumosudil

ADJUST DOSING INTERVAL: Administration with food increases the oral bioavailability of belumosudil. The mechanism has not been described. Administration of belumosudil (200 mg single oral dose) in healthy subjects, with a fatty and calorie-rich meal (approximately half of the calories were contained in the fat) increased the mean belumosudil peak plasma concentration (Cmax) and area under the concentration-time curve (AUC) by 120% and 100%, respectively, compared to administration under fasting conditions. The time to reach peak concentration (Tmax) was delayed by 30 minutes. Administration of oral belumosudil 200 mg once daily with food in patients with chronic graft-versus-host disease (chronic GVHD) lead to steady-state concentrations of the drug with an accumulation ration of 1.4.

MANAGEMENT: To ensure maximal oral absorption, belumosudil should be administered with a meal, every day at the same time.

Minor

armodafinil food

Applies to: armodafinil

Administration with food may delay the absorption of modafinil (the racemate) and armodafinil (the R-enantiomer) without significantly affecting their overall bioavailability. According to the product labeling, modafinil's absorption may be delayed by approximately one hour if taken with food. Similarly, the time to reach peak plasma concentration (Tmax) of armodafinil may be delayed by approximately 2 to 4 hours in the fed state.

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.
