Mechanism of action

Nicotine is an alkaloid that acts as an agonist at nicotinic acetylcholine receptors, mimicking the effects of acetylcholine. By delivering controlled doses of nicotine without the harmful combustion products of tobacco, it reduces the reinforcing effects of smoking and alleviates withdrawal symptoms such as irritability, anxiety, and difficulty concentrating. The 2 mg formulation is typically delivered via chewing gum and is designed for gradual dose reduction as part of a smoking cessation program.
