How APLENZIN Works

The exact mechanism of action is unknown, though the drug's effects are presumed to be mediated by noradrenergic and dopaminergic mechanisms. It functions as a relatively weak inhibitor of the neuronal uptake of norepinephrine and dopamine. Unlike some other classes of antidepressants, this medication does not inhibit monoamine oxidase or the reuptake of serotonin.
