Mechanism of action

It has the potential to lessen the craving and withdrawal symptoms brought on by quitting smoking because it is a high-affinity partial agonist for the nicotinic acetylcholine receptor subtype (nACh) 42. When activated, nACh causes the release of the neurotransmitter dopamine in the nucleus accumbens reward centre of the brain.


Varenicline is an anti-smoking medication that works by preventing the effects of nicotine in the brain, which are responsible for the desire to smoke and is thus prescribed to adults who are attempting to quit the habit of smoking (smoking cessation).
