Sintesi
Arsenic trioxide causes marked QT prolongation and torsades de pointes, and quinine adds to this effect. The combination may result in life-threatening arrhythmias.
Cosa significa questa interazione in parole semplici
Arsenic trioxide and Quinine 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.
Arsenic trioxide belongs to Oncology; Quinine belongs to Anti Parasitic.
Perché avviene
Additive pharmacodynamic QT prolongation through cardiac potassium channel effects.
Cosa fare
Avoid the combination; use a non-QT-prolonging antimalarial or cramp treatment during arsenic trioxide therapy. If quinine is essential for severe malaria, monitor ECG continuously and keep electrolytes corrected.
