Acute bromopride treatments: effects on general activity and inhibitory avoidance in rats.

Bromopride (BRO), a dopamine D2 blocker used in gastroenterology clinics, was tested acutely in rats for effects on general activity, measured in an open-field test, and on inhibitory avoidance behavior. Rats that received 2.5 and 5.0 mg/kg BRO showed lower locomotion and rearing frequencies than controls, and 5.0 mg/kg BRO blocked the inhibitory avoidance response. The data suggest that BRO may have neuroleptic effects.
