Summary
Both salbutamol and the loop diuretic torsemide can lower serum potassium. Together, particularly with high-dose or nebulised salbutamol, hypokalemia may be more pronounced and could provoke arrhythmias.
What this interaction means in plain words
Ipratropium-salbutamol 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.
Ipratropium-salbutamol belongs to Respiratory; Torsemide belongs to Cardiovascular.
Why it happens
Beta2-agonist-driven intracellular potassium shift adds to renal potassium loss caused by the loop diuretic.
What to do
Check serum potassium and magnesium when starting or during frequent salbutamol use, and replace potassium as needed. Take extra care in patients with heart disease or on digoxin.
