Summary
Loxapine is a dopamine D2 antagonist and bromocriptine is a D2 agonist, so they oppose each other. Loxapine can reduce bromocriptine's efficacy in hyperprolactinemia, acromegaly or Parkinson disease. Single inhaled doses give a more limited effect than chronic dosing.
What this interaction means in plain words
Bromocriptine and Loxapine inhaled 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 D2 receptors.
What to do
Avoid regular use together if possible; if inhaled loxapine is needed for acute agitation, monitor for loss of bromocriptine effect or worsening motor symptoms.
