Ultimo aggiornamento
Per operatori sanitari — solo a scopo di riferimento. Questa pagina è una sintesi breve, non è un parere medico e non sostituisce il RCP ufficiale né il giudizio clinico. Verificare sempre prima di prescrivere o dispensare.
Il contenuto clinico di questa pagina è disponibile solo in inglese.
Sintesi
Both drugs are dopamine antagonists that prolong the QT interval, and droperidol carries a boxed warning for torsades de pointes. Combined use markedly increases arrhythmia risk and additive sedation.
Cosa significa questa interazione in parole semplici
Chlorpromazine and Droperidol 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.
Perché avviene
Additive blockade of cardiac potassium channels with QT prolongation, plus additive CNS depression.
Cosa fare
Avoid using together; select an antiemetic or sedative without QT effects. If unavoidable, use continuous ECG monitoring and correct electrolytes.
