Resumo
Both drugs prolong the QT interval, and arsenic trioxide is known to cause torsades de pointes and complete AV block. Together they markedly raise the risk of life-threatening ventricular arrhythmia. Ziprasidone labeling lists this combination as contraindicated.
O que esta interação significa em palavras simples
Arsenic trioxide and Ziprasidone 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.
Arsenic trioxide belongs to Oncology; Ziprasidone belongs to Central Nervous System.
Por que acontece
Additive prolongation of cardiac repolarization through delayed rectifier potassium channel (hERG) blockade.
O que fazer
Do not co-administer; use an antipsychotic with lower QT liability if one is needed during arsenic trioxide therapy. Correct potassium and magnesium and monitor ECGs if any antipsychotic is unavoidable.
