Metabolite Identification
Common NameVarenicline
DescriptionVarenicline is a prescription medication used to treat smoking addiction. This medication is the first approved nicotinic receptor partial agonist. Specifically, varenicline is a partial agonist of the alpha4/beta2 subtype of the nicotinic acetylcholine receptor. In addition it acts on alpha3/beta4 and weakly on alpha3beta2 and alpha6-containing receptors. A full agonism was displayed on alpha7-receptors.
