Résumé

Apalutamide may reduce exposure to irinotecan and its active metabolite SN-38, potentially lowering antitumor efficacy. Inducers of CYP3A4 are known to reduce irinotecan exposure.

Ce que signifie cette interaction, en termes simples

Apalutamide and Irinotecan 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.

Apalutamide belongs to Endocrine; Irinotecan belongs to Oncology.

Niveau de preuve: Moderate

Pourquoi elle survient

CYP3A4 induction by apalutamide increases irinotecan clearance, including conversion to inactive oxidized metabolites.
