Mechanism of action

Nicotine acts as an agonist at nicotinic acetylcholine receptors in the central and peripheral nervous system. The polacrilex formulation is an ion-exchange resin complex that slowly releases nicotine in the mouth, allowing transmucosal absorption. This sustained delivery helps maintain adequate nicotine levels to suppress withdrawal symptoms and reduce the reinforcing effects of smoking.
