Bupropion hydrochloride increases the levels of the chemicals dopamine, serotonin, and norepinephrine in the brain. This helps improve mood and can lessen cravings for nicotine. Bupropion is a weak blocker of the neuronal uptake of serotonin, dopamine and norepinephrine and is a central nicotinic acetylcholine receptor antagonist. Bupropion may also reduce circulating levels of tumor necrosis factor (TNF) and normalize hypothalamic-pituitary-adrenal (HPA) axis functioning, which is dysregulated in certain cases of cancer-related fatigue.
Bupropion is a non-nicotine aid to help you quit smoking by reducing withdrawal symptoms. It can be taken alone or with a nicotine replacement product (generally with a nicotine gum or lozenge). Bupropion is recommended along with a tobacco cessation program in order to provide you with additional support and educational materials.
