摘要
Arsenic trioxide has a boxed warning for QT prolongation, torsades de pointes and complete AV block. Granisetron can also lengthen the QT interval, so the combination increases arrhythmia risk.
用白話說明這項交互作用的意義
Arsenic trioxide and Granisetron 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.
Arsenic trioxide belongs to Oncology; Granisetron belongs to Gastrointestinal Tract.
為什麼會發生
Additive pharmacodynamic QT prolongation.
處置方式
Avoid other QT-prolonging drugs where possible and consider an antiemetic with less QT effect. If granisetron is needed, correct potassium and magnesium and monitor ECG throughout arsenic trioxide therapy.
