Nicorette Classic Gum (Nicotine Resinate)

Nicotine Resinate, delivered via Nicorette Classic Gum, is used in nicotine replacement therapy to support smoking cessation.

• Smoking cessation: provides controlled nicotine to reduce cravings and withdrawal symptoms.
• Tobacco dependence: assists adult smokers in transitioning away from cigarettes by delivering steady nicotine levels.
• Relapse prevention: helps maintain abstinence by managing occasional urges during quit attempts.

• Nicotine Resinate acts as an agonist at nicotinic acetylcholine receptors in the central nervous system. By binding to these receptors, it produces low‑level nicotine stimulation that mimics the pharmacologic effect of tobacco smoke, thereby attenuating the neurochemical changes that underlie withdrawal and craving during cessation attempts.
