Abstract

Cytisine acts as a selective ∂4ß2 nicotinic acetylcholine receptor (nAChR) partial agonist. It can increase dopamine receptor stimulation in the central nervous system and plays a crucial role in reducing nicotine withdrawal symptoms. Clinical studies have shown that a 25-day course of cytisine, with a designated quit date on the fifth day of treatment, results in smoking cessation rates significantly superior to both placebo and nicotine replacement therapy (NRT). The incidence of adverse effects is low, with the most commonly reported being gastrointestinal side effects (nausea and vomiting). Consequently, cytisine is recommended for smoking cessation in patients who do not respond to first-line therapies or as a combination treatment with NRT.
