Marketed as the antidepressant Wellbutrin and the smoking cessation product Zyban, bupropion increases the levels of dopamine and norepinephrine in the brain synapses. It has an unknown mechanism of action but is clearly different from antidepressants in other classes, such as SSRIs, SNRIs, and tricyclics; therefore, bupropion belongs in its own category. It's sometimes used off label to treat ADHD, sexual dysfunction from SSRI/SNRI, and weight gain from other medications, and possibly ADHD.
The following table lists the potential pros and cons for this popular medication in the treatment of bipolar disorder.
