Interactions between your drugs

Moderate

DOXOrubicin abrocitinib

Applies to: doxorubicin and abrocitinib

MONITOR: Coadministration with abrocitinib may increase the plasma concentrations of drugs that are substrates of P-glycoprotein (P-gp), an efflux transporter inhibited in vitro by abrocitinib. Concomitant administration of dabigatran etexilate, a P-gp substrate, and abrocitinib (200 mg single dose) increased the dabigatran peak plasma concentration (Cmax) and systemic exposure (AUC) by approximately 40% and 53%, respectively. The effect of abrocitinib on pharmacokinetics of other P-gp substrates has not been evaluated.

MANAGEMENT: Caution is advised if abrocitinib is coadministered with P-gp substrates, particularly sensitive substrates or those with a narrow therapeutic range. Dosage adjustments as well as clinical and laboratory monitoring may be appropriate for some drugs whenever abrocitinib is added to or withdrawn from therapy.

Drug and food interactions

Moderate

abrocitinib food

Applies to: abrocitinib

MONITOR: Smoking during treatment with abrocitinib may increase the risk of major adverse cardiovascular events (MACE) and the risk of developing malignancies. During abrocitinib clinical studies, current or past smokers had an additional increased risk of overall malignancies. Also, abrocitinib may increase patients' risk of MACE, including myocardial infarction, stroke, and cardiovascular death.

Administration of abrocitinib with high-fat, high-calorie food increased abrocitinib peak plasma concentration (Cmax) and systemic exposure (AUC) by 29% and 26%, respectively, and prolonged the time to reach Cmax by 2 hours. These changes are not considered clinically relevant.

MANAGEMENT: Caution is advised if abrocitinib is prescribed to current or past smokers. Patients should be informed about the symptoms of serious cardiovascular events and the steps to take if they occur. The manufacturer recommends discontinuing abrocitinib in patients that have experienced a myocardial infarction or stroke. Abrocitinib may be taken with or without food.

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.
