title: Effects of acute and chronic bupropion on locomotor activity and dopaminergic neurons.
abstract: Acute administration of bupropion (10 or 30 mg/kg) to rats increased locomotor activity in a dose-related manner. The highest dose increased the dopamine (DA) concentration while both doses reduced the concentration of dihydroxyphenylacetic acid (DOPAC) in the striatum. The enhancement of locomotor activity and the decrease of striatal DOPAC concentrations were increased with chronic administration (up to 40 days) of bupropion. The rate of DA synthesis in the striatum was increased by the acute administration of d-amphetamine but was not altered by acute or chronic administration of bupropion.
