Summary
Dopexamine is a catecholamine-like agent given by infusion in hospital settings, and pimozide blocks dopamine receptors, so the dopaminergic effects of dopexamine may be reduced. Pimozide may also add to hypotension through alpha-adrenergic blockade.
What this interaction means in plain words
Dopexamine and Pimozide 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, with additive hypotensive effects from alpha-blockade.
What to do
Monitor blood pressure, heart rate and hemodynamic response during dopexamine infusion and titrate the dose to effect.
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?
