Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Partial agonist at α4β2 nicotinic acetylcholine receptors; also full agonist at α7 nicotinic receptors. Reduces nicotine craving and withdrawal symptoms while blocking nicotine's reinforcing effects.
Nicotine is a nicotinic acetylcholine receptor agonist. It binds to and activates nicotinic acetylcholine receptors in the brain, leading to dopamine release and other neurotransmitter effects that mediate nicotine dependence and withdrawal symptoms.
1 mg orally twice daily after starting a 1-week titration: days 1-3: 0.5 mg once daily; days 4-7: 0.5 mg twice daily; day 8 onward: 1 mg twice daily.
Inhalation: 1 cartridge (4 mg) inhaled as needed for craving relief, up to 16 cartridges per day; typical initial dose: 4-8 cartridges per day, with weaning over 12 weeks.

Terminal elimination half-life is approximately 24 hours. Clinical context: Steady-state is achieved within 4 days; significant accumulation occurs in renal impairment (creatinine clearance <30 mL/min), requiring dose adjustment.
2 hours (range 1-4 h). Shorter in smokers due to induction of metabolism; prolonged in renal impairment.
Renal: 81% unchanged, 8% as metabolites; Fecal: <10% (as metabolites); Biliary: minimal.
Primarily renal (10-20% unchanged; 80-90% as metabolites, mainly cotinine and nicotine-N'-oxide). Biliary/fecal excretion accounts for <10%.
