Summary
Atenolol blocks beta-1 receptors and can blunt the cardiac stimulation and hemodynamic benefit expected from dopexamine, a beta-2 and dopamine agonist. Response to dopexamine may be unpredictable in beta-blocked patients.
What this interaction means in plain words
Atenolol and Dopexamine 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
Pharmacodynamic antagonism at beta-adrenergic receptors.
What to do
Monitor hemodynamic response closely and titrate dopexamine to effect; consider a different inotrope if the beta-blocker cannot be held in an acute setting.
What to ask your pharmacist
- Should I take them at different times of day?
- Does the dose of either medicine need to change?
- Is there anything I should avoid, such as alcohol or certain foods, while on both?
