How Wellbutrin Affects Neurotransmitters
How Wellbutrin Works
Bupropion inhibits reuptake of dopamine and norepinephrine — a completely different mechanism from SSRIs and SNRIs. It has no significant serotonergic activity, which explains its absence of sexual side effects and GI disturbance. The dopaminergic mechanism provides activating, motivating effects.
