Both drugs can prolong the QT interval, and systemic pentamidine has been associated with torsades de pointes. Combined use raises the risk of life-threatening ventricular arrhythmia.

Ce que signifie cette interaction, en termes simples

Clomipramine and Pentamidine 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.
