Resumo
Apalutamide is a strong CYP3A4 inducer and lowers brexpiprazole exposure, since brexpiprazole is cleared by CYP3A4 and CYP2D6. This can lead to loss of antipsychotic efficacy and relapse.
O que esta interação significa em palavras simples
Apalutamide and Brexpiprazole 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; Brexpiprazole belongs to Central Nervous System.
Por que acontece
Induction of CYP3A4 by apalutamide increases brexpiprazole metabolism and lowers plasma concentrations.
O que fazer
Brexpiprazole labeling advises doubling the dose when a strong CYP3A4 inducer is added, with reduction back to the usual dose if the inducer is stopped. Monitor clinical response, or consider an alternative to apalutamide where possible.
