How does Varenicline Work?
Varenicline has a higher-affinity and partial agonism for the α4β2 nicotinic acetylcholine receptor subtype. When activated, it releases dopamine in the nucleus accumbens. Therefore, it reduces withdrawal caused by smoking cessation. The partial agonism on the α4β2 receptors produces less effect of dopamine release than nicotine's deemed better than nicotine's full agonism.
