Summary
Droperidol blocks dopamine D2 receptors and can blunt dopamine's dopaminergic effects, while also having alpha-blocking properties that may lower blood pressure. Dopamine's pressor response may therefore be less predictable.
What this interaction means in plain words
Dopamine and Droperidol 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 dopamine receptors plus alpha-adrenergic blockade by droperidol.
What to do
Monitor blood pressure and perfusion and titrate dopamine to response. Consider an alternative antiemetic if hypotension persists.
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?
