Sintesi

Arsenic trioxide markedly prolongs the QT interval and can cause torsade de pointes. Vilanterol may add to this through beta-agonist effects on heart rate and potassium, raising arrhythmia risk in an already vulnerable patient.

Cosa significa questa interazione in parole semplici

Arsenic trioxide and Fluticasone-vilanterol can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.

Arsenic trioxide belongs to Oncology; Fluticasone-vilanterol belongs to Respiratory.

Livello di evidenza: Moderate

Perché avviene

Additive QT prolongation with beta2-agonist-related hypokalemia and sympathetic stimulation.
