Summary
Indacaterol, a long-acting beta2-agonist, can lower serum potassium, and the effect may be potentiated by non-potassium-sparing diuretics such as torsemide. Hypokalemia can predispose to arrhythmias, especially with hypoxia.
What this interaction means in plain words
Indacaterol inhaled and Torsemide 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
Beta2-mediated potassium shift into cells added to loop diuretic urinary potassium loss.
What to do
Monitor serum potassium periodically, particularly in severe COPD or with other risk factors. Supplement potassium if levels fall.
