Summary
Both drugs can lower serum potassium, and the combined effect may cause clinically significant hypokalemia, particularly with high-dose or nebulised salbutamol. Hypokalemia can promote arrhythmias.
What this interaction means in plain words
Bumetanide and Salbutamol 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.
Bumetanide belongs to Cardiovascular; Salbutamol belongs to Respiratory.
Why it happens
Additive hypokalemia: beta-2 stimulation shifts potassium into cells and loop diuretics increase renal potassium loss.
What to do
Monitor serum potassium, especially in acute asthma or in patients with heart disease or on digoxin; supplement potassium as needed.
