Summary
Both drugs lower serum potassium, so combined use can produce clinically significant hypokalemia, particularly with high-dose or frequent beta-agonist dosing. Hypokalemia increases the risk of arrhythmias and muscle weakness.
What this interaction means in plain words
Levosalbutamol 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.
Levosalbutamol belongs to Respiratory; Torsemide belongs to Cardiovascular.
Why it happens
Beta-2 agonism shifts potassium into cells while the loop diuretic increases renal potassium loss.
What to do
Monitor serum potassium and magnesium, especially in acute asthma or COPD exacerbations. Replace potassium as needed.
