Sintesi
Fluphenazine is a phenothiazine antipsychotic that blocks hERG potassium channels and can lengthen the QTc, and pimozide has a pronounced dose-related QTc-prolonging effect. Using them together adds to delayed repolarisation and raises the risk of torsades de pointes, especially with hypokalaemia, hypomagnesaemia, bradycardia or structural heart disease.
Cosa significa questa interazione in parole semplici
Fluphenazine and Pimozide 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.
Fluphenazine belongs to Central Nervous System; Pimozide belongs to Central Nervous System.
Perché avviene
Additive blockade of cardiac repolarising potassium currents (hERG)
Cosa fare
Do not co-prescribe; choose an agent without QT liability. If one drug cannot be stopped, correct electrolytes and monitor the ECG closely.
