Journal of the Formosan Medical Association = Taiwan Yi Zhi
|September 25, 1998
Summary
Transdermal nicotine patches significantly reduced nicotine dependence and withdrawal symptoms in Chinese smokers. The patch aided smoking cessation, though long-term abstinence rates showed no significant difference compared to placebo.
Area of Science:
- Addiction Medicine
- Pharmacology
Background:
- Nicotine withdrawal syndrome is a major barrier to smoking cessation.
- Nicotine replacement therapy (NRT) can alleviate withdrawal symptoms.
Purpose of the Study:
- To evaluate the efficacy and safety of a 30-mg transdermal nicotine patch for smoking cessation in Chinese smokers.
Main Methods:
- Randomized, double-blind, placebo-controlled trial.
- 62 heavy smokers (≥20 cigarettes/day for >1 year) participated.
- Intervention: 30-mg transdermal nicotine patch vs. placebo for 6 weeks.
Main Results:
- Nicotine patch group showed reduced nicotine dependence and withdrawal symptoms after 6 weeks.
- 6-week cessation rates: 63% (nicotine patch) vs. 34% (placebo).
- 1-year abstinence rates: 30% (nicotine patch) vs. 9% (placebo); p=0.08.
Conclusions:
- Transdermal nicotine patch is an effective aid for short-term smoking cessation.
- Minimal side-effects were observed.
- Further research may be needed to confirm long-term efficacy differences.
