Filter by:This is a brief smoking cessation trial in women, comparing transdermal nicotine patch (TNP) versus varenicline.
The goal of this study is to examine the effects of a GABA (gamma amino butyric acid)-enhancing medication, pregabalin (300 mg/day), on smoking behavior, tobacco withdrawal and cigarette craving in smokers. We hypothesize that in smokers, pregabalin at 300 mg/day, will be more effective than placebo in decreasing smoking behavior and attenuating tobacco withdrawal and cigarette craving.
This project aims to define mechanisms through which varenicline might be an effective smoking cessation medication.
A teachable moment (TM) refers to life events or transitions, such as physician visits, early detection screening feedback, pregnancy, and hospitalization for, and diagnosis of, disease, that inspire health behavior change. Despite strong intuitive appeal of the TM concept and over 150 studies of interventions implemented in a TM, there has been little investigation of the influence of TMs for smoking, particularly for promoting smoking cessation among those indirectly affected by a TM (e.g., relatives of cancer patients). This prospective observational study using a matched-group design will assess whether a lung cancer diagnosis increases enrollment in a smoking cessation program and cessation, and reduces smoking, among the patient's relatives/spouse who smoke. We will compare enrollment in a cessation program and cessation and smoking rates in 2 groups of smokers: 1) relatives/spouses of newly-diagnosed lung cancer patients, and 2) relatives/spouses of patients with an orthopedic condition. We will also explore mediators and moderators of a lung cancer diagnosis as a TM. This study could clarify the TM concept for smoking cessation, shed light on the underlying mechanisms of TMs, and guide future development and implementation of TM-based smoking cessation interventions.
The purpose of this study is to test whether Varenicline can help ambivalent smokers (those who are interested in quitting at some point in the future but have no current plans to quit) to reduce their smoking and eventually quit.
The purpose of this study is to compare gain-framed counseling + gain-framed materials" to standard care Quitline counseling + standard print materials. The investigators hypothesize that gain-framed counseling + gain-framed materials group will produce higher abstinence rates than standard care counseling and standard care information. The data in this study will be used to determine effect size estimates for a large scale study.
The primary purpose of this study is to determine whether, among smokers with elevated depressive symptoms, sequential antidepressant pharmacotherapy with fluoxetine (20 mg) begun 8 weeks prior to and extended throughout standard smoking cessation treatment with transdermal nicotine patch (ST-TNP) will result in superior short-and long-term smoking cessation outcomes compared to sequential pharmacotherapy with placebo medication combined with ST-TNP. The secondary aim of the study is to test the hypothesis that, among smokers with elevated depressive symptoms, sequential treatment with fluoxetine will result in lower levels of depressive symptoms and negative mood and higher levels of positive mood immediately prior to and throughout the course of smoking cessation treatment relative to the placebo condition.
Cocaine addiction continues to be an important public health problem in the US with a significant cost to the individual and society. Among substance abusers, cocaine use has been recognized as a significant problem especially in methadone-maintenance patients. In several studies, rates of cocaine use have been reported to range from 30 to over 60 percent of those in methadone maintenance programs (Condelli et al. 1991; Hunt et al. 1984; Kidorf and Stitzer 1993; Kosten et al. 1988). In these patients, cocaine use seems to be a predictor of poor clinical outcome (Hartel et al. 1995; Kosten et al. 1987a). The development of effective pharmacotherapies for cocaine use disorders, especially in the opioid-dependent population is of great importance. Unfortunately, such effective pharmacotherapies do not exist. 1. To determine the safety and tolerability of varenicline in cocaine-using methadone-stabilized subjects. 2. To determine if varenicline is efficacious in reducing cocaine-use in methadone-stabilized subjects.
The purpose of this study is to determine whether a combination of naltrexone SR and bupropion SR is safe and effective in the treatment of nicotine-dependence in overweight and obese subjects.
The purpose of this study is to determine whether the combination of naltrexone (Depade) and varenicline (Chantix) minimizes post-smoking cessation weight gain and how well the combination is tolerated.
