Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Nicotine acts as an agonist at nicotinic acetylcholine receptors, stimulating dopamine release in the nucleus accumbens, which mediates reward and craving reduction.
Nicotine replacement therapy; binds to nicotinic acetylcholine receptors in the brain, reducing withdrawal symptoms and cravings by providing a controlled dose of nicotine.
Transdermal: Apply one patch daily. Initial dose based on smoking history: >10 cigarettes/day: 21 mg/day patch; ≤10 cigarettes/day: 14 mg/day patch. Titrate to 7 mg/day patch as tolerated.
Initial: 3.5 mg transdermally once daily for 4 weeks, then increase to 7 mg/24 hr; maximum dose 21 mg/24 hr.

2 hours (nicotine); 16 hours (cotinine metabolite) — accumulation with chronic use.
Terminal half-life: 24 hours (range 20-28 h). Prolonged in moderate to severe hepatic impairment (up to 40 h). Clinical context: allows once-daily transdermal dosing for smoking cessation.
Primarily renal (10-20% unchanged; 60-70% as metabolites cotinine and nicotine-N'-oxide); 5-10% biliary/fecal.
Primarily renal: approximately 60% as unchanged drug and metabolites. Fecal: <10%. Biliary: negligible.
