How Chantix works as an agonist of nicotinic acetylcholine receptor?
Varenicline, the active ingredient in Chantix works as a partial agonist of the alpha4beta2 nicotinic acetylcholine receptor. In addition, it acts on alpha3beta4 and weakly on alpha3beta2 and alpha6-containing receptors. By acting as an agonist, Chantix helps to relieve nicotine withdrawal symptoms and reduces the rewarding properties of nicotine, thereby aiding smoking cessation.
