Behavioral suppression following 3,4-methylenenedioxymethamphetamine.
Rotation in rats was employed as an assay of the central dopaminergic activity of 3,4-methylenedioxymethamphetamine (MDMA). This agent was observed to possess predominantly amphetamine-like actions at low doses. However, at higher doses it also appears to stimulate the dopamine receptor directly. Following a third dose of MDMA, a significant decrease in rotation was evident to this drug and to amphetamine, suggesting a neurotoxic or long-term suppressive action of MDMA.
