buPROPion brentuximab vedotin

Applies to: Wellbutrin XL (bupropion) and brentuximab

MONITOR: Coadministration of brentuximab vedotin with other agents known to induce hepatotoxicity may potentiate the risk of liver injury. Serious cases of hepatotoxicity, some fatal, have occurred in patients treated with brentuximab vedotin. Cases were consistent with hepatocellular injury, including elevations of transaminases and/or bilirubin, and typically occurred after the first dose or after a rechallenge. Preexisting liver disease and elevated baseline liver enzymes may also increase the risk.

MANAGEMENT: The risk of hepatic injury should be considered when brentuximab vedotin is used with other agents that are potentially hepatotoxic (e.g., acetaminophen; alcohol; androgens and anabolic steroids; antituberculous agents; azole antifungal agents; ACE inhibitors; cyclosporine (high dosages); disulfiram; endothelin receptor antagonists; interferons; ketolide and macrolide antibiotics; kinase inhibitors; minocycline; nonsteroidal anti-inflammatory agents; HIV reverse transcriptase inhibitors; proteasome inhibitors; retinoids; sulfonamides; tamoxifen; thiazolidinediones; tolvaptan; vincristine; zileuton; anticonvulsants such as carbamazepine, hydantoins, felbamate, and valproic acid; lipid-lowering medications such as fenofibrate, lomitapide, mipomersen, niacin, and statins; herbals and nutritional supplements such as black cohosh, chaparral, comfrey, DHEA, kava, pennyroyal oil, and red yeast rice). Patients should be advised to seek medical attention if they experience potential signs and symptoms of hepatotoxicity such as fever, rash, itching, anorexia, nausea, vomiting, fatigue, malaise, right upper quadrant pain, dark urine, pale stools, and jaundice. Liver enzymes and bilirubin should be measured before and during treatment, especially in patients with underlying hepatic disease or marked baseline transaminase elevations. Patients experiencing new, worsening, or recurrent hepatotoxicity may require a delay, change in dosage, or discontinuation of brentuximab vedotin in accordance with the product labeling.

Drug and food interactions

Moderate

buPROPion food

Applies to: Wellbutrin XL (bupropion)

GENERALLY AVOID: Excessive use or abrupt discontinuation of alcohol after chronic ingestion may precipitate seizures in patients receiving bupropion. Additionally, there have been rare postmarketing reports of adverse neuropsychiatric events or reduced alcohol tolerance in patients who drank alcohol during treatment with bupropion. According to one forensic report, a patient died after taking large doses of both bupropion and alcohol. It is uncertain whether a drug interaction was involved. Single-dose studies in healthy volunteers given bupropion and alcohol failed to demonstrate either a significant pharmacokinetic or pharmacodynamic interaction.

MANAGEMENT: The manufacturer recommends that alcohol consumption be minimized or avoided during bupropion treatment. The use of bupropion is contraindicated in patients undergoing abrupt discontinuation of alcohol.

buPROPion food

Applies to: Wellbutrin XL (bupropion)

MONITOR: Additive or synergistic effects on blood pressure may occur when bupropion is combined with sympathomimetic agents such as nasal decongestants, adrenergic bronchodilators, ophthalmic vasoconstrictors, and systemic vasopressors. Treatment with bupropion can result in elevated blood pressure and hypertension. In clinical practice, hypertension, in some cases severe and requiring acute treatment, has been observed in patients receiving bupropion alone and in combination with nicotine replacement therapy. These events have occurred in both patients with and without evidence of preexisting hypertension. Furthermore, postmarketing cases of hypertensive crisis have been reported during the initial titration phase with bupropion-naltrexone treatment.

MANAGEMENT: Caution is advised when bupropion is used with other drugs that increase dopaminergic or noradrenergic activity due to an increased risk of hypertension. Blood pressure and heart rate should be measured prior to initiating bupropion therapy and monitored at regular intervals consistent with usual clinical practice, particularly in patients with preexisting hypertension. Dose reduction or discontinuation of bupropion should be considered in patients who experience clinically significant and sustained increases in blood pressure or heart rate.

buPROPion food

Applies to: Wellbutrin XL (bupropion)

MONITOR: The concomitant use of bupropion and nicotine replacement for smoking cessation may increase the risk of hypertension. In a clinical study (n=250), 6.1% of patients who used sustained-release bupropion with nicotine transdermal system developed treatment-emergent hypertension, compared to 2.5% of patients treated with bupropion alone, 1.6% treated with nicotine alone, and 3.1% treated with placebo. Three patients in the bupropion plus nicotine group and one patient in the nicotine-only group discontinued treatment due to hypertension. The majority had evidence of preexisting hypertension.

MANAGEMENT: Blood pressure monitoring is recommended for patients concomitantly using bupropion and nicotine replacement for smoking cessation.

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.
