Bupropion is the generic name for a prescription medication which
is also known by the brand names Wellbutrin and Zyban, among others.
Among other things, Bupropion is commonly used to treat major depressive
disorder and seasonal affective disorder.
It was first synthesized by Burroughs Research way back in 1966. It
was approved by the Food and Drug Administration (FDA) as an antidepressant
in 1984, and marketed under the name Wellbutrin. It was removed from
the market in 1986 (because of a significant incidence of seizures)
and re-introduced to the market in 1989 (with a new maximum dosage
allowed in order to reduce the incidence of seizures).
In 1996 the FDA approved sustained-release (SR) and in 2003 extended
release (XL) formulations of Wellbutrin that release Bupropion at
a slower rate.
