Summary
Enzalutamide reduces brigatinib exposure through enzyme induction. Reduced exposure may compromise control of ALK-positive lung cancer.
What this interaction means in plain words
Brigatinib and Enzalutamide can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
Brigatinib belongs to Oncology; Enzalutamide belongs to Endocrine.
Why it happens
CYP3A4 induction by enzalutamide increases brigatinib clearance.
What to do
Avoid concurrent use. If a strong inducer cannot be avoided, brigatinib labeling advises increasing the dose in stepwise fashion and reducing it again after the inducer is stopped.
