Ce que signifie cette interaction, en termes simples

Apalutamide and Valbenazine 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; Valbenazine belongs to Central Nervous System.

Niveau de preuve: High

Pourquoi elle survient

Apalutamide induces CYP3A4, which metabolizes valbenazine and its active metabolite.
