摘要

Vorinostat has been associated with QT prolongation, and thioridazine markedly prolongs QTc. The combination may increase the risk of torsades de pointes, particularly with electrolyte disturbances common in oncology patients.

用白話說明這項交互作用的意義

Thioridazine and Vorinostat 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.

Thioridazine belongs to Central Nervous System; Vorinostat belongs to Oncology.

證據等級: Moderate

為什麼會發生

Additive effects on cardiac repolarization leading to QT prolongation.

處置方式

Avoid combining; use an alternative antipsychotic. If vorinostat is essential, correct potassium and magnesium and do not use thioridazine.
