Interactions between your drugs

Major

nintedanib lumacaftor

Applies to: Ofev (nintedanib) and ivacaftor / lumacaftor

GENERALLY AVOID: Coadministration with inducers of P-glycoprotein (P-gp) and CYP450 3A4 may decrease the plasma concentrations of nintedanib, which is a substrate of the efflux transporter and a minor substrate of the isoenzyme. In a dedicated drug interaction study, administration of nintedanib with the potent P-gp and CYP450 3A4 inducer, rifampin, decreased nintedanib peak plasma concentration (Cmax) and systemic exposure (AUC) by 40% and 50%, respectively, compared to administration of nintedanib alone. No data are available for use with other, less potent inducers.

MANAGEMENT: Concomitant use of nintedanib with P-gp and CYP450 3A4 inducers should generally be avoided due to the potential for reduced efficacy.

ivacaftor nintedanib

Applies to: ivacaftor / lumacaftor and Ofev (nintedanib)

MONITOR: Coadministration with inhibitors of P-glycoprotein (P-gp) and CYP450 3A4 may increase the plasma concentrations of nintedanib, which is a substrate of the efflux transporter and a minor substrate of the isoenzyme. In a dedicated drug interaction study, administration of nintedanib with the potent P-gp and CYP450 3A4 inhibitor, ketoconazole, increased nintedanib peak plasma concentration (Cmax) by 83% and systemic exposure (AUC) by 61%. No data are available for use with other, less potent inhibitors.

MANAGEMENT: Caution is advised if nintedanib is prescribed in combination with P-gp and CYP450 3A4 inhibitors. Pharmacologic response to nintedanib should be monitored more closely whenever a CYP450 3A4/P-gp inhibitor is added to or withdrawn from therapy, and the nintedanib dosing adjusted or interrupted as necessary in accordance with the product labeling. Patients should be closely monitored for increased adverse effects such as liver enzyme and bilirubin elevations, diarrhea, nausea, vomiting, gastrointestinal perforation, bleeding, and arterial thromboembolic events (e.g., myocardial infarction).

Drug and food interactions

Moderate

ivacaftor food

Applies to: ivacaftor / lumacaftor

GENERALLY AVOID: Grapefruit juice may increase the plasma concentrations of ivacaftor. The proposed mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruit. Elexacaftor and tezacaftor are also CYP450 3A4 substrates in vitro and may interact similarly with grapefruit juice, whereas lumacaftor is not expected to interact.

ADJUST DOSING INTERVAL: According to prescribing information, systemic exposure to ivacaftor increased approximately 2.5- to 4-fold, systemic exposure to elexacaftor increased approximately 1.9- to 2.5-fold, and systemic exposure to lumacaftor increased approximately 2-fold following administration with fat-containing foods relative to administration in a fasting state. Tezacaftor exposure is not significantly affected by administration of fat-containing foods.

MANAGEMENT: Patients treated with ivacaftor-containing medications should avoid consumption of grapefruit juice and any food that contains grapefruit or Seville oranges. All ivacaftor-containing medications should be administered with fat-containing foods such as eggs, avocados, nuts, meat, butter, peanut butter, cheese pizza, and whole-milk dairy products. A typical cystic fibrosis diet will satisfy this requirement.

nintedanib food

Applies to: Ofev (nintedanib)

ADJUST DOSING INTERVAL: Food enhances the oral bioavailability of nintedanib. After food intake, nintedanib exposure increased by approximately 20% compared to administration under fasted conditions. Absorption was also delayed, as indicated by an increase in the median time to reach maximum plasma concentration (Tmax) from 2 hours in the fasted state to approximately 4 hours under fed conditions, irrespective of the type of food ingested.

MANAGEMENT: Nintedanib should be administered with 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.
