​

Dopamine is strongly associated with pleasure and reward. Of course, it’s not as simple as just that. In fact, there’s a lot more to this complex chemical.

Dopamine is involved in neurological and physiological functioning. It’s a contributing factor in motor function, mood, and even our decision making. It’s also associated with some movement and psychiatric disorders.

Explanation:

It acts by blocking the uptake of synaptic dopamine via the dopamine transporter (DAT). In addition to blocking dopamine uptake, bupropion has other potentially therapeutic actions, such as blockade of nicotinic acetylcholine receptors and norepinephrine uptake.
