Bupropion, sold under the brand names Wellbutrin and Zyban among others, is a medication primarily used to treat major depressive disorder and to support stopping smoking.[8] It is a moderately effective antidepressant on its own, but it is also used as an add-on medication in cases of incomplete response to first-line SSRI antidepressants.[8][10] Bupropion is taken in tablet form and is available only by prescription in industrialized countries.[8]
Common side effects include a dry mouth, difficulty sleeping, agitation, and headaches.[8] Serious side effects include an increased risk for epileptic seizures and suicide.[8] In comparison to some other antidepressants, bupropion may have a lower rate of sexual dysfunction or sleepiness and may result in weight loss.[11] It is unclear if its use during pregnancy or breastfeeding is safe.[8][2]
Bupropion is an atypical antidepressant.[12] It acts as a norepinephrine–dopamine reuptake inhibitor (NDRI) and a nicotinic receptor antagonist.[11][13][13][14] Chemically, it is an aminoketone that belongs to the class of substituted cathinones and is similar to phenethylamines.[1][15]
Bupropion was first made by chemist Nariman Mehta in 1969, and patented by Burroughs Wellcome in 1974.[16] It was first approved for medical use in the United States in 1985.[8] It was originally called by the generic name amfebutamone, before being renamed in 2000.[17] It is on the World Health Organization's List of Essential Medicines.[18] In the United States, the wholesale cost per dose is less than US$0.50 as of 2018[update].[19] In 2017, it was the 23rd most commonly prescribed medication in the United States, with more than 24 million prescriptions.[20][21]
