Smoking cessation: nicotine replacement, gums and patches.

Area of Science:

• Clinical Medicine
• Pulmonology
• Addiction Medicine

Background:

• Smoking remains a leading cause of preventable morbidity and mortality.
• Effective smoking cessation strategies are crucial for public health.
• Pulmonary healthcare providers play a key role in patient cessation support.

Purpose of the Study:

• To provide a clinical overview of smoking cessation methods.
• To evaluate the efficacy of nicotine replacement therapies (NRTs) and bupropion.
• To highlight the importance of behavioral support in smoking cessation.

Main Methods:

• Review of clinical approaches to smoking cessation.
• Analysis of data on nicotine replacement products (different forms and combinations).
• Assessment of bupropion's efficacy compared to NRTs.
• Evaluation of the impact of behavioral support and early abstinence.

Main Results:

• Nicotine replacement therapies approximately double long-term smoking cessation success rates.
• Different NRT administration forms show equal long-term efficacy; combination therapy offers no additional long-term benefit.
• Adjunctive behavioral support significantly increases cessation success rates.
• Total abstinence in the first week post-quit-day strongly predicts long-term success.
• Bupropion demonstrates comparable efficacy to NRTs and is a promising cessation aid.

Conclusions:

• Nicotine replacement therapies are effective, with efficacy influenced by dose but not administration form.
• Behavioral support and achieving early abstinence are critical for sustained smoking cessation.
• Bupropion is an effective alternative to NRTs for smoking cessation.
• Healthcare professionals in pulmonary units must offer current smoking cessation services.
