Summary
Dexamethasone can reduce brigatinib exposure via CYP3A4 induction, potentially lowering antitumor efficacy in ALK-positive lung cancer. The effect is more certain with strong inducers than with dexamethasone.
What this interaction means in plain words
Brigatinib and Dexamethasone 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.
Brigatinib belongs to Oncology; Dexamethasone belongs to Endocrine.
Why it happens
Dexamethasone induces CYP3A4, increasing brigatinib metabolism.
What to do
Limit the dose and duration of dexamethasone where possible and monitor for loss of tumor response. If a strong inducer is required, follow the brigatinib labeled dose adjustment.
