Résumé

Ibutilide markedly prolongs repolarization and causes torsades de pointes; adding methadone, which also prolongs QT, further raises this risk. The arrhythmia can be rapid and fatal.

Ce que signifie cette interaction, en termes simples

Ibutilide and Methadone 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.

Ibutilide belongs to Cardiovascular; Methadone belongs to Musculoskeletal.

Niveau de preuve: Moderate

Pourquoi elle survient

Additive pharmacodynamic QT prolongation via potassium channel (hERG) blockade.

Conduite à tenir

Do not give together; use an alternative rhythm-control strategy such as electrical cardioversion if appropriate. If methadone cannot be withheld, ensure continuous ECG monitoring and correct electrolytes, accepting substantial risk.
