Summary
Both drugs stimulate adrenergic receptors, so combining them can produce additive tachycardia, arrhythmias, blood pressure changes and a fall in serum potassium. The risk is highest in patients with cardiac disease or baseline hypokalemia.
What this interaction means in plain words
Dopexamine and Pirbuterol 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 beta-adrenergic agonism, with beta-2 mediated intracellular potassium shift.
What to do
Monitor heart rate, rhythm and blood pressure continuously during dopexamine infusion. Check serum potassium and replace it if low.
What to ask your pharmacist

- Does the dose of either medicine need to change?
