Bupropion is primarily prescribed to treat which of the following conditions?

Bupropion is primarily prescribed to treat depression and assist in smoking cessation. It is classified as an atypical antidepressant and works by inhibiting the reuptake of neurotransmitters such as dopamine and norepinephrine, which helps alleviate symptoms of depression. Its second notable use is in promoting smoking cessation; it is marketed under the name Zyban for this purpose. By reducing cravings and withdrawal symptoms associated with nicotine dependence, bupropion can be an effective tool for individuals trying to quit smoking.

The combination of these two treatments underscores its effectiveness in addressing both mood disorders and substance use issues, making it unique compared to other antidepressants that do not have the smoking cessation component.
