NCIt definition : The hydrobromide salt of an aminoketone with antidepressant activity. The molecular
mechanism of the antidepressant effect of bupropion is unknown. This agent does not

a weak blocker of the neuronal uptake of serotonin and norepinephrine. Buproprion
also weakly inhibits the neuronal re-uptake of dopamine.;
