Plasma nicotine levels produced by chewing nicotine gum

Area of Science:

• Pharmacology
• Addiction Medicine
• Respiratory Medicine

Background:

• Nicotine gum aims to support smoking cessation by managing nicotine dependence.
• It addresses the behavioral aspects of smoking alongside nicotine withdrawal.

Purpose of the Study:

• To compare plasma nicotine levels from nicotine gum with those from cigarette smoking.
• To assess the efficacy and acceptability of nicotine gum for smoking cessation in patients with lung disease.

Main Methods:

• Nine patients with lung disease participated in the study.
• Plasma nicotine levels were measured after hourly chewing of 2-mg and 4-mg nicotine gum.
• These levels were compared to nicotine levels achieved through usual and hourly cigarette smoking.

Main Results:

• Hourly chewing of 2-mg and 4-mg nicotine gum yielded mean steady-state plasma nicotine levels of 11.8 ng/mL and 23.2 ng/mL, respectively.
• These levels were comparable to trough levels from usual smoking (15.7 ng/mL) and hourly smoking (18.3 ng/mL).
• Minimal side effects were reported for both 2-mg and 4-mg nicotine gum.

Conclusions:

• Nicotine gum is an acceptable nicotine source for smoking cessation.
• It effectively maintains plasma nicotine levels, aiding individuals in coping with smoking withdrawal.
• The study supports nicotine gum's role in smoking cessation programs, particularly for patients with lung disease.
