Resumo
Vandetanib markedly prolongs the QT interval and has been associated with torsades de pointes and sudden death. Adding amitriptyline, which also prolongs QT, increases that risk further.
O que esta interação significa em palavras simples
Amitriptyline and Vandetanib 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.
Amitriptyline belongs to Central Nervous System; Vandetanib belongs to Oncology.
Por que acontece
Additive QT prolongation through cardiac potassium channel effects.
O que fazer
Avoid the combination and choose a non-QT-prolonging antidepressant. If a QT-prolonging drug cannot be avoided, use intensive ECG and electrolyte monitoring.
