To better understand smoking cessation, we examined the actions of varenicline (Chantix) during long-term nicotine exposure. Varenicline reduced nicotine upregulation of α4β2-type nicotinic receptors (α4β2Rs) in live cells and neurons, but not for membrane preparations. Effects on upregulation depended on intracellular pH homeostasis and were not observed if acidic pH in intracellular compartments was neutralized. Varenicline was trapped as a weak base in acidic compartments and slowly released, blocking (125)I-epibatidine binding and desensitizing α4β2Rs...

BACKGROUND: Meta-analyses of clinical trial data have identified clinically relevant gender differences in the efficacy of smoking cessation pharmacotherapy. It is unclear whether these findings are generalizable to smokers quitting in real-world contexts. METHODS: Using Tobacco Use Supplement to the Current Population Survey (TUS-CPS) 2010-2011 cross-sectional data, we generated propensity score matched samples of smokers who quit either unassisted by medication, using only varenicline, or using only transdermal nicotine patch (TNP)...

BACKGROUND: People with severe mental ill health are more likely to smoke than those in the general population. It is therefore important that effective smoking cessation strategies are used to help people with severe mental ill health to stop smoking. This study aims to assess the effectiveness and cost -effectiveness of smoking cessation and reduction strategies in adults with severe mental ill health in both inpatient and outpatient settings. METHODS: This is an update of a previous systematic review...

Medications for smoking cessation, such as nicotine replacement, bupropion and varenicline have comparable efficacy, but present different advantages and drawbacks, making patient-specific preferences important when choosing a medication for smoking cessation. Through 3 PDCA cycles (Plan-Do-Check-Act), we developed and user-tested a decision aid for use during consultations. It contains the most relevant information for choosing a smoking cessation medication and is freely available online. The methodology used for its development could be employed for other decision aids for preference-sensitive decisions...

OBJECTIVE: Smoking cessation treatment should be an important aspect of cancer care. In this study, we evaluated whether cancer-related disease factors adversely influence smoking cessation treatment. METHODS: Smokers with cancer (within 5 years of diagnosis, any tumor site) were recruited for an ongoing trial of varenicline for smoking cessation. Disease factors, assessed at baseline, included tumor site, cancer treatment, time since diagnosis, and health-related quality of life (HRQOL)...

INTRODUCTION: Cigarette smoking is one of the leading causes of early death in the UK and worldwide. Public health guidance recommends the use of varenicline, bupropion and nicotine replacement therapy (NRT) as smoking cessation aids in the UK. Additionally, the first electronic cigarette has been licensed for use as a smoking cessation medicine. However, there are ongoing concerns about the safety of these medicines. We present a protocol for a systematic review and network meta-analysis (NMA) to determine how these smoking cessation medicines compare to each other with respect to their neuropsychiatric safety in adult smokers...

BACKGROUND: Most alcoholics experience periods of voluntary alcohol abstinence or imposed alcohol deprivation followed by a return to alcohol drinking. This study examined whether varenicline (VAR) reduces alcohol intake during a return to drinking after periods of alcohol deprivation in rats selectively bred for high alcohol drinking (the alcohol preferring or "P" rats). METHODS: Alcohol-experienced P rats were given 24-hour access to food and water and scheduled access to alcohol (15% and 30% v/v) for 2 h/d...

BACKGROUND: In 2009, the FDA required a black box warning (BBW) on bupropion and varenicline, the two commonly prescribed smoking cessation agents due to reports of adverse neuropsychiatric events. We investigated if there was a decline in use of bupropion and varenicline after the BBW by comparing the percent using these medications before and after BBW. METHODS: We conducted a retrospective observational study using data from the Medical Expenditure Panel Survey from 2007 to 2014...

RATIONALE: Clinical trials and human laboratory studies have established that varenicline can reduce rates of alcohol use among heavy drinkers. Less is known about the mechanisms by which varenicline has this effect on drinking behavior. Reactivity to alcohol cues is often cited as the primary cause of relapse among those being treated for alcohol use disorder, and several front-line treatments for alcohol use disorder work, at least in part, by minimizing cue-induced alcohol craving...

Introduction: Bupropion and varenicline are non-nicotine medications used for smoking cessation that mitigate craving and withdrawal symptoms. We aim to investigate whether these drugs increase the risk of selected acute adverse outcomes when used in medical practice. Methods: Population-based case-crossover design using data from Swedish health and administrative registers. Adult individuals diagnosed with acute myocardial infarction, stroke, suicide, suicide attempt, fall injury, or that suffered a road traffic crash from 01...

A cation-π interaction between the ammonium group of an agonist and a conserved tryptophan termed TrpB is a near universal feature of agonist binding to nicotinic acetylcholine receptors (nAChRs). TrpB is one of five residues that form the aromatic box of the agonist binding site, and for the prototype agonists ACh and nicotine, only TrpB makes a functional cation-π interaction. We report that, in addition to TrpB, a significant cation-π interaction is made to a second aromatic, TyrC2, by the agonists metanicotine, TC299423, varenicline, and nornicotine...

BACKGROUND: Prevalence of smoking among individuals with posttraumatic stress disorder (PTSD) is disproportionately high, and PTSD is associated with especially poor response to smoking cessation treatment. OBJECTIVE: The current study examined whether integrating treatments for smoking cessation (varenicline plus smoking cessation counseling; VARCC) and PTSD (prolonged exposure therapy; PE) enhances smoking outcomes among smokers diagnosed with PTSD. METHOD: 142 adults with nicotine dependence (ND) and PTSD were randomized to a treatment program consisting of varenicline, smoking cessation counseling, and PE (VARCC + PE) or to VARCC only...

Firsthand and secondhand tobacco use is linked to a multitude of harmful illnesses, adverse perinatal outcomes, and death. Cessation attempts among women may be hampered by their unique biologic response to nicotine. Current research has revealed epigenetic changes from intrauterine nicotine exposure that have intergenerational consequences. Multiple studies have demonstrated the efficacy of various pharmacologic tobacco cessation interventions in conjunction with behavioral counseling. Based on this evidence, the US Preventative Services Task Force (USPSTF) 2015 guideline recommends pharmacologic therapy for all nonpregnant persons who smoke in addition to behavioral counseling...

INTRODUCTION: The nicotine-metabolite ratio (NMR) predicts treatment response and is related to treatment side effect severity. Sleep disturbance may be one important side effect, but understanding sleep disturbance effects on smoking cessation is complicated by the fact that nicotine withdrawal also produces sleep disturbance. AIMS: To evaluate the effects of withdrawal and treatment side effects on sleep disturbance. METHODS: This is a secondary analysis of data from a clinical trial (Lerman et al...

Premature mortality due to cardiovascular disease in those with schizophrenia is the largest lifespan disparity in the US and is growing; adults in the US with schizophrenia die, on average, 28 years earlier than those in the general population. The rate of smoking prevalence among individuals with schizophrenia is estimated to be from 64 to 79%. Smokers with schizophrenia have historically been excluded from most large nicotine-dependence treatment studies. However, converging evidence indicates that a majority of smokers with schizophrenia want to quit smoking, and that available pharmacotherapeutic smoking cessation aids are well tolerated by this population of smokers and are effective when combined with behavioral treatment...
