Summary
Apalutamide induces UGT enzymes and CYP enzymes, which may lower febuxostat concentrations since febuxostat is cleared partly by glucuronidation and CYP oxidation. This could reduce urate-lowering efficacy.
What this interaction means in plain words
Apalutamide and Febuxostat 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.
Apalutamide belongs to Endocrine; Febuxostat belongs to Genitourinary.
Why it happens
Induction of UGT and CYP enzymes by apalutamide increases febuxostat clearance.
What to do
Monitor serum uric acid after starting apalutamide and increase the febuxostat dose within labeled limits if the target is not reached.
