Bupropion or bupropion hydrochloride, also known formerly as amfebutamone, is a medication primarily used as an antidepressant and smoking cessation aid. It is one of the most frequently prescribed antidepressants in the United States, although in many English-speaking countries, including the United Kingdom, Australia and New Zealand, this is an off-label use. Chemically, bupropion is in the aminoketone family. Bupropion serves as an atypical antidepressant different from most commonly prescribed antidepressants such as selective serotonin reuptake inhibitors (SSRIs). It is an effective antidepressant on its own, but is also popular as an add-on medication in cases of incomplete response to first-line SSRI antidepressants.
