Resumo
Isavuconazole is a moderate CYP3A4 inhibitor, and pimozide is a CYP3A4 substrate with a narrow margin of safety. Higher pimozide levels can cause serious QT prolongation and ventricular arrhythmias, and other azoles are contraindicated with pimozide.
O que esta interação significa em palavras simples
Isavuconazonium 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.
Isavuconazonium belongs to Anti Fungals; Pimozide belongs to Central Nervous System.
Por que acontece
CYP3A4 inhibition by isavuconazole raises pimozide concentrations, adding to its QT liability.
O que fazer
Avoid concomitant use and choose a different antifungal or antipsychotic. If unavoidable, close ECG monitoring is required.
O que perguntar ao farmacêutico

- If both are essential, who is monitoring me and how often?
