>Supposedly, unlike amphetamine, which both inhibits reuptake and stimulates release of neurotransmiters, bupropion only inhibits uptake of neurotransmitters. OK, that part I understand. But doesn't cocaine work the same way that bupropion does (inhibiting uptake of NE, 5HT, and DA)? Why is cocaine a stim, and Wellbutrin an antidepressant. <Cocaine acts more like a stimulant than Wellbutrin, because it stimulates the release of dopamine, as well as inhibiting reuptake. As I understand it, what happens in cocaine addiction is that the body begins to shut down some receptors in response to over-stimulation, which causes withdrawal effects and reinforces the whole addictive process.
