Resumo
Enzalutamide is a strong CYP3A4 inducer and also induces CYP2C9. Erdafitinib is cleared by CYP2C9 and CYP3A4, so exposure may fall and its antitumor effect may be reduced.
O que esta interação significa em palavras simples
Enzalutamide and Erdafitinib 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.
Enzalutamide belongs to Endocrine; Erdafitinib belongs to Oncology.
Por que acontece

O que fazer
