Resumo
Ibutilide markedly prolongs repolarisation and carries a significant risk of torsades de pointes. Adding maprotiline, which also lengthens the QT interval, further increases the likelihood of life-threatening ventricular arrhythmia.
O que esta interação significa em palavras simples
Ibutilide and Maprotiline 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; Maprotiline belongs to Central Nervous System.
Por que acontece
Additive pharmacodynamic prolongation of the QT interval.
O que fazer
Do not give ibutilide to patients taking maprotiline; consider an alternative cardioversion strategy such as electrical cardioversion. Review the need for maprotiline if rhythm control with QT-prolonging agents is planned.
