Little is known about the impact of alcohol involvement on smoking cessation relapse or possible mechanisms for these associations. We addressed these issues using data from a randomized clinical trial of two types of framed messages (gain vs. loss) in conjunction with open label sustained-release (SR) bupropion (Toll et al.

Method: The National Institute on Alcohol Abuse and Alcoholism COMBINE (Combining Medications and Behavioral Interventions) study, a randomized controlled double-blind trial of 1,383 alcohol-dependent patients, compared combinations of medications (acamprosate [Campral] and naltrexone [ReVia]) and behavioral therapy (medical management and specialist-delivered behavioral therapy) for alcohol dependence. This report focuses on a subset of that study population (n = 466) receiving (1) specialized behavioral therapy alone (without pills), (2) specialized behavioral therapy + placebo medication + medical management, or (3) placebo + medical management.
Background: American Indians and Alaska Natives have the highest rates of nicotine dependence in the U.S. However, studies analyzing associations between nicotine dependence and psychiatric and substance use disorders in these groups have been limited.

At present, there are no published dose-ranging clinical trials of the oral preparation for treatment of problem drinking. The present study evaluated the effects of Ntx on alcohol use among the subset of hazardous drinkers (n=102) who participated in a placebo-controlled, dose-ranging trial of oral Ntx (25-mg, 50-mg and 100-mg doses) combined with open-label transdermal nicotine patch for enhancing smoking cessation.

To date, three medications have been approved for the treatment of alcohol dependence: disulfiram (Antabuse®), naltrexone (Revia®, Vivitrol®, and Naltrel®), and acamprosate (Campral®). However, these medications have modest efficacy, and there is a great need for newer medications that target different neurochemical systems and which could be used either as adjunctive treatments or to treat subpopulations of drinkers.

However, most studies do not do so, often because of the extra time burden required for these assessments. Data from participants (N=634) in two smoking cessation clinical trials were used to examine the relationship between short and longer periods of monitoring for a number of Timeline Followback (TLFB) drinking metrics at baseline and during treatment.

While plasma nicotine concentration measures only acute nicotine exposure, plasma, salivary, and urine cotinine concentrations reflect exposure over an extended period of time. Although, expired carbon monoxide (CO) is frequently used to confirm self reports, it has a relatively short half life, calling into question whether this measure might provide misleading information by exaggerating smoking cessation success rates.

Naltrexone, an opiate receptor antagonist, is approved for the treatment of alcohol dependence. This double-blind placebo-controlled study examined whether the efficacy of naltrexone would be augmented by concurrent treatment with sertraline, a selective serotonin receptor uptake inhibitor (SSRI).

We sought to determine whether topiramate's antidrinking effects are bolstered by improvements in physical and psychosocial well-being.
Methods: In a 17-site, 14-week, double-blind, randomized controlled trial, we compared the effects of topiramate (up to 300 mg/d) vs placebo on physical health, obsessional thoughts and compulsions about using alcohol, and psychosocial well-being among 371 alcohol-dependent subjects who received weekly adherence enhancement therapy.
Heavy drinking young adults often have limited motivation to change their drinking behavior. Adding pharmacotherapy to brief counseling is a novel approach to treating this population. A small open-label pilot study was conducted to assess the feasibility of offering eight weeks of daily and targeted (i.

The objective was to evaluate the efficacy of naltrexone alone and in combination with sertraline among Alaska Natives and other Alaskans living in rural settings. An exploratory aim examined whether the Asn40Asp polymorphism of the mu-opioid receptor gene (OPRM1) predicted response to naltrexone, as had been reported in Caucasians.

Objective: To evaluate whether individuals with alcoholism who are heterozygous (Asp40/Asn40) or homozygous (Asp40/Asp40) for the OPRM1 Asp40 allele respond better to naltrexone.
Because quitting smoking is clearly linked to preventing health problems such as lung cancer, research on health message framing based on prospect theory suggests that gain-framed messages (i.e., emphasizing the benefits of quitting smoking) would be more persuasive in promoting cessation than loss-framed messages (i.
View Article and Find Full Text PDFProspect theory suggests that because smoking cessation is a prevention behavior with a fairly certain outcome, gain-framed messages will be more persuasive than loss-framed messages when attempting to encourage smoking cessation. To test this hypothesis, the authors randomly assigned participants (N=258) in a clinical trial to either a gain- or loss-framed condition, in which they received factually equivalent video and printed messages encouraging smoking cessation that emphasized either the benefits of quitting (gains) or the costs of continuing to smoke (losses), respectively. All participants received open label sustained-release bupropion (300 mg/day) for 7 weeks.

Rationale: Nicotine replacement is commonly used to treat tobacco use in heavy-drinking smokers. However, few studies have examined the effect of nicotine replacement on subjective and physiological responses to alcohol and alcohol drinking behavior.
Objective: The primary aim of this within-subject, double-blind study was to examine whether transdermal nicotine replacement (0 mg vs 21 mg/day) altered response to a low-dose priming drink and subsequent ad libitum drinking behavior.
Extended-release naltrexone (XR-NTX) is a once-a-month injectable formulation that is Food and Drug Administration-approved for the treatment of alcohol dependence in patients able to abstain from alcohol before treatment initiation. This paper presents the results of an analysis of efficacy data from a subgroup of patients with 4 days or more of voluntary abstinence before treatment initiation (n = 82) on a wide range of drinking-related outcomes. In these patients, all of whom received counseling, the rate of abstinence was severalfold higher for XR-NTX 380 mg compared with placebo: median time to first drink was 41 days versus 12 days, respectively; rate of continuous abstinence at end of the study was 32% versus 11% (P = 0.

The nicotinic acetylcholine receptor (nAChR) system has been implicated in a variety of psychiatric disorders, including tobacco smoking, for which there is strong evidence supporting sex differences in behaviors and response to smoking cessation treatments. We examined the availability of nAChR containing the beta(2) subunit in healthy men and women and the influence of menstrual phase among women.

A major obstacle to the development of medications for nicotine dependence is the lack of animal and human laboratory models with sufficient predictive clinical validity to support the translation of knowledge from laboratory studies to clinical research. This Review describes the animal and human laboratory paradigms commonly used to investigate the pathophysiology of nicotine dependence, and proposes how their predictive validity might be determined and improved, thereby enhancing the development of new medications.

Methods: Participants (n=74) who met current criteria for cocaine abuse or dependence were randomized to three-session cognitive-behavioral therapy (CBT) or three-session enhanced CBT (MET+CBT), which included an initial session of motivational enhancement therapy (MET). Outcome measures included treatment retention, process measures (e.
The authors examined the factor structure of the Minnesota Nicotine Withdrawal Scale (MNWS) using confirmatory factor analysis in 3 clinical research samples of smokers trying to quit (N = 723). Three confirmatory factor analytic models, based on previous research, were tested with each of the 3 study samples at multiple points in time. A unidimensional model including all 8 MNWS items was found to be the best explanation of the data.
