Summary
Netupitant is metabolized mainly by CYP3A4, and induction by bosentan can lower its concentrations. Reduced exposure could lessen the antiemetic protection against chemotherapy-induced nausea.
What this interaction means in plain words
Bosentan and Netupitant / palonosetron can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Why it happens
Bosentan induces CYP3A4, accelerating netupitant metabolism.
What to do
Avoid in patients chronically on bosentan if possible. Otherwise monitor for breakthrough nausea and vomiting and add rescue antiemetics.
