Summary
Vilanterol is a beta2-agonist that can slightly prolong QTc and lower potassium, though systemic exposure after inhalation is low. With amisulpride the added risk is small but relevant in patients with cardiac risk factors.
What this interaction means in plain words
Amisulpride and Vilanterol / fluticasone furoate inhaled can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Why it happens
Additive QT effects, with beta2-agonist-related hypokalemia potentiating amisulpride.
What to do
Use labeled doses and check potassium in at-risk patients. Obtain an ECG if other QT-prolonging factors are present.
