Resumo
Dacomitinib strongly inhibits CYP2D6, which is the main route of thioridazine clearance. Higher thioridazine levels increase the risk of QT prolongation and torsades de pointes.
O que esta interação significa em palavras simples
Dacomitinib and Thioridazine are not normally used together. Taking them at the same time is expected to cause harm or make one of them unsafe, so a different medicine is usually chosen for one of the two.
Dacomitinib belongs to Oncology; Thioridazine belongs to Central Nervous System.
Por que acontece
Dacomitinib inhibits CYP2D6, reducing thioridazine metabolism and raising its concentrations.
O que fazer
Avoid the combination; use an antipsychotic not dependent on CYP2D6 or an alternative EGFR inhibitor. If unavoidable, monitor ECG closely.
O que perguntar ao farmacêutico
