Varenicline tartrate is an orally active, subtype-selective partial agonist at alpha4beta2 nicotinic receptors with Ki values of 0.06, 240, 322 and 3540 nM for alpha4beta2, alpha3beta4, alpha7, alpha1betaidelta receptors respectively, and a full agonist at alpha7 neuronal nicotinic receptors. In humans, following oral administration, varenicline is almost completely absorbed and has high bioavailability (90%). Varenicline stimulates basal mesolimbic dopamine release to approximately 50% of the maximal effect of nicotine, inhibits nicotine-induced dopamine release, and reduces nicotine self-administration. Varenicline is a clinically useful smoking cessation agent.
