Filter by:The goal of this clinical research study is learn if the combination of Chantix (varenicline) and Zyban (bupropion) is more effective at helping people to quit smoking than varenicline when given alone. Researchers also want to learn if this drug combination can reduce cravings and other negative symptoms of nicotine withdrawal better than varenicline does alone. The safety of this drug combination will also be tested.
This is a pilot research study examining the use of varenicline (Chantix) and the nicotine patch. The study is designed to find out whether one of these medications is more effective for smoking cessation with head and neck cancer patients. The study has three parts: 1) two intake sessions; 2) an 8-week treatment phase, and 3) a 3-month follow-up.
This research study is being done to find out if adding a moderate exercise program or a relaxation program to a smoking cessation treatment program will improve smoking cessation and health in postmenopausal women. We hope to learn which group is more successful at quitting, has less symptoms of withdrawal from smoking and has improved health.
Smoking is the leading cause of preventable morbidity and mortality in the US. While approximately 70% of smokers attempt to quit each year, only 5-15% maintain abstinence for 12 months, even with effective pharmacological and psychological interventions. Novel therapies are needed for smoking cessation and relapse prevention. Previous studies show that early post-cessation craving or urge to smoke is a powerful predictor of relapse. A current model of the pathogenesis of addiction maintains that a substance of abuse causes a marked increase release in phasic dopamine release, which in turn strengthens or increases the salience of the memory of the drug experience, leading to a powerful and persistent memory that is easily activated, leading to drug craving and often to drug use. This highly salient memory is also implicated in the physiological arousal associated with craving responses to smoking cues. This process is thought to be implicated in relapse to drug use after even long periods of abstinence. Recent animal research indicates that retrieval returns a consolidated memory such as those associated with drug craving, to a labile state from which it must be restabilized to persist in a process termed reconsolidation. If memories of drug-related experiences are labile when reactivated, this could represent a window of opportunity in which the memory of drug use that underlies drug craving can be influenced pharmacologically. Our hypothesis is that post-reactivation administration of the B-adrenergic blocker, propranolol, following retrieval of drug-associated memories will reduce the strength or salience of the memory by influencing reconsolidation, a process called memory reconsolidation blockade. In this study we will test the hypothesis that a single dose of propranolol given one hour prior to smoking-related cue exposure (post-reactivation treatment) will decrease psychophysiological responses to smoking cues one week later and will predict clinical response to an ensuing series of 6 post-reactivation treatments with script-driven imagery and propranolol. In order to do so, we propose to conduct a randomized, double-blind, placebo-controlled trial of post-reactivation treatment with propranolol in 50 adult smokers. Outcome measures will include in physiological responses to smoking-related cues after one and six post-reactivation treatments and smoking behavior during the treatment and during a 3-month follow-up period.
The purpose of this research study is to learn about the efficacy of a medication called varenicline (Chantix) in treating ADHD in adults and in reducing cigarette smoking in adults with ADHD. The investigators hypothesize that ADHD symptomatology in adults with ADHD will be improved with varenicline treatment. The investigators also hypothesize that varenicline treatment will result in significant reductions in cigarette smoking. Another objective of this study is to more fully evaluate the response and tolerability to varenicline in this group of cigarette smoking adults with ADHD.
Nicotine replacement therapy (NRT) is a well-tolerated and efficacious smoking cessation treatment, and yet many smokers fail to quit using NRT. Many of these smokers may benefit from prescription treatment alternatives, including Zyban or Chantix. In this study, the investigators propose to develop and evaluate a stepped-care treatment algorithm that would evaluate whether smokers who receive treatment with NRT should be supplemented with Zyban or switched to Chantix only based on: 1) their initial response to NRT; and 2) individual genetic factors found to predict smoking cessation in other studies evaluating these treatments. This study is a continuation of our previous studies showing that abstinence rates can be increased by starting nicotine patch therapy two weeks before the quit date. The investigators will provide pre-cessation NRT to all participants initially. Those who do not show a favorable response on early indicators of success (e.g., smoking in the first week after the target quit-smoking date) will receive "rescue" treatment by having their NRT treatment supplemented with Zyban , by being switched to treatment with Chantix or will remain on NRT (control). The investigators hypothesize that "Rescue" treatment with Zyban in combination with NRT or Chantix will increase success rates over leaving subjects on NRT when they are NRT insufficient responders, i.e. they have shown an unfavorable response to NRT in the first week pre-quit or the first week post-quit.
It is possible to offer smoking cessation treatment including varenicline to patients scheduled for elective surgery. This study will evaluate whether or not this will enable some patients to quit smoking for up to 4 weeks prior to surgery and in turn, whether this may lead to reductions in post-operative complication such as wound infections.
The purpose of this study is to see if automated telephone monitoring will enhance existing quitline services, such as Alere Wellbeing's Quit For Life program, and help people quit smoking. If successful, this intervention could be incorporated into existing quitline protocols and delivered to millions of people who are trying to quit smoking.
A comparison of a novel nicotine replacement therapy and placebo treatment in smokers motivated to quit smoking.
The goal of this study is to determine the effectiveness of a general intervention that includes encouragement of physical activity and healthy living habits of officers and permanent staff in the IDF
