Interactions between your drugs

Major

ibuprofen zanubrutinib

Applies to: NeoProfen (ibuprofen) and zanubrutinib

MONITOR CLOSELY: Coadministration of zanubrutinib and drugs that interfere with platelet function or coagulation may potentiate the risk of bleeding complications. Serious and fatal hemorrhagic events have been reported during zanubrutinib therapy. Grade 3 or higher bleeding events including intracranial and gastrointestinal hemorrhage, hematuria, and hemothorax have been reported in up to 4% of patients treated with zanubrutinib monotherapy, with fatalities occurring in 0.3% of patients. Overall, bleeding events of any grade, including purpura and petechiae, occurred in nearly 55% of patients, both with and without concomitant antiplatelet or anticoagulation therapy. The mechanism for the bleeding events is not well understood, although treatment with zanubrutinib commonly causes thrombocytopenia. Grade 3 or 4 thrombocytopenia was reported in up to 11.5% of patients treated with zanubrutinib monotherapy.

MANAGEMENT: Concomitant use of zanubrutinib in patients receiving other medications that interfere with platelet function or coagulation should be approached with caution. Close clinical and laboratory monitoring for bleeding complications is recommended during therapy. Patients should be advised to promptly report any signs and symptoms of bleeding to their physician. Discontinue zanubrutinib if intracranial hemorrhage of any grade occurs. Refer to the product labeling for dose adjustment or discontinuation of therapy recommendations if Grade 3 or higher adverse reactions occur.

Drug and food interactions

Major

zanubrutinib food

Applies to: zanubrutinib

GENERALLY AVOID: Grapefruit and/or grapefruit juice may increase the plasma concentrations of zanubrutinib. The proposed mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruit. Inhibition of hepatic CYP450 3A4 may also contribute. The interaction has not been studied with grapefruit juice, but has been reported for other CYP450 3A4 inhibitors. When zanubrutinib was administered with the potent CYP450 3A4 inhibitor itraconazole (200 mg once daily) in clinical study subjects, zanubrutinib peak plasma concentration (Cmax) and systemic exposure (AUC) increased by 157% and 278%, respectively. Data derived from pharmacokinetic modeling have also been reported for several additional CYP450 3A4 inhibitors. For example, the potent CYP450 3A4 inhibitor clarithromycin (250 mg twice daily) is predicted to increase zanubrutinib Cmax and AUC by 175% and 183%, respectively. The moderate CYP450 3A4 inhibitor diltiazem (60 mg three times daily) is predicted to increase zanubrutinib Cmax and AUC by 151% and 157%, respectively. Another moderate CYP450 3A4 inhibitor, erythromycin (500 mg four times daily), is predicted to increase zanubrutinib Cmax and AUC by 284% and 317%, respectively. Likewise, fluconazole 200 mg once daily is predicted to increase zanubrutinib Cmax and AUC by 179% and 177%, respectively; while fluconazole 400 mg once daily is predicted to increase zanubrutinib Cmax and AUC by 270% and 284%, respectively. In general, the effects of grapefruit products are concentration-, dose- and preparation-dependent, and can vary widely among brands. Certain preparations of grapefruit (e.g., high dose, double strength) have sometimes demonstrated potent inhibition of CYP450 3A4, while other preparations (e.g., low dose, single strength) have typically demonstrated moderate inhibition. Increased zanubrutinib exposure may potentiate the risk of toxicities such as hemorrhage, infection, cytopenias, malignancies, and serious cardiac arrhythmias (primarily atrial fibrillation and atrial flutter).

Food does not affect the oral bioavailability of zanubrutinib. No clinically significant differences in zanubrutinib Cmax or AUC were observed following administration of a high-fat meal (approximately 1000 calories; 50% from fat) in healthy subjects.

MANAGEMENT: Zanubrutinib may be administered with or without food. Patients should avoid consumption of grapefruit, grapefruit juice, Seville oranges, and Seville orange juice during treatment with zanubrutinib.

Moderate

ibuprofen food

Applies to: NeoProfen (ibuprofen)

GENERALLY AVOID: The concurrent use of aspirin or nonsteroidal anti-inflammatory drugs (NSAIDs) and ethanol may lead to gastrointestinal (GI) blood loss. The mechanism may be due to a combined local effect as well as inhibition of prostaglandins leading to decreased integrity of the GI lining.

MANAGEMENT: Patients should be counseled on this potential interaction and advised to refrain from alcohol consumption while taking aspirin or NSAIDs.

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.
