Summary
Both drugs are beta-adrenergic agonists, so combining them can increase heart rate, provoke arrhythmias and lower serum potassium. Patients with ischemic heart disease or those already critically ill are most vulnerable.
What this interaction means in plain words
Dobutamine 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.
Dobutamine belongs to Cardiovascular; Salbutamol belongs to Respiratory.
Why it happens
Additive beta-adrenergic stimulation and beta-2 mediated intracellular potassium shift.
What to do
Monitor ECG, heart rate, blood pressure and serum potassium during concurrent use. Replace potassium and reduce the dose of one agent if tachyarrhythmia occurs.
What to ask your pharmacist

- Does the dose of either medicine need to change?
- Is there anything I should avoid, such as alcohol or certain foods, while on both?
