Summary
Droperidol carries a boxed warning for QT prolongation and torsades de pointes, and pazopanib also prolongs the QT interval. The combination may markedly raise arrhythmia risk.
What this interaction means in plain words
Droperidol and Pazopanib 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.
Why it happens
Additive QT prolongation through cardiac repolarization effects.
What to do
Use an antiemetic with less QT liability such as one without QT effects. If droperidol is essential, obtain an ECG and correct electrolytes beforehand and monitor the rhythm.
