简要总结
This study will test a combination of the drugs naltrexone and bupropion with weight-concerned smokers to investigate whether or not this combination of drugs improves smoking cessation quit rates and minimizes post quit weight gain.
详细描述
This is an open label smoking cessation clinical trial of 25 mg naltrexone with 300 mg bupropion sustained-release (SR) in six male and fourteen female participants. This pilot study is being conducted to determine:
- effect size estimates for smoking cessation and post-cessation weight gain, which will be used to compute the sample size needed for a large-scale clinical trial; and
- compliance with a combination of 25 mg naltrexone and 300 mg bupropion SR. In addition to examining the sample in this study, the investigators plan to compare this sample to a sample of matched controls.

研究组 & 干预措施
Bupropion only
The placebo comparator was a group of matched controls who received an identical psychosocial intervention and bupropion SR treatment regimen in a similar 7-week study investigation compared to naltrexone hydrochloride (25 mg/day) in combination with bupropion hydrochloride SR (300 mg/day).
干预措施: Bupropion (Drug)
Naltrexone +Bupropion
The active comparator in this 7-week open label study investigation was naltrexone hydrochloride (25 mg/day) in combination with bupropion hydrochloride SR (300 mg/day) compared to matched controls who received an identical psychosocial intervention and bupropion SR treatment regimen (bupropion only).
干预措施: Naltrexone (Drug)
Naltrexone +Bupropion
The active comparator in this 7-week open label study investigation was naltrexone hydrochloride (25 mg/day) in combination with bupropion hydrochloride SR (300 mg/day) compared to matched controls who received an identical psychosocial intervention and bupropion SR treatment regimen (bupropion only).
