baclofen AND alcohol

Anel A Jaramillo, Patrick A Randall, Suzanne Frisbee, Joyce Besheer
The nucleus accumbens core (AcbC) is a key brain region known to regulate the discriminative stimulus/interoceptive effects of alcohol. As such, the goal of the present work was to identify AcbC projection regions that may also modulate sensitivity to alcohol. Accordingly, AcbC afferent projections were identified in behaviorally naïve rats using a retrograde tracer which led to the focus on the medial prefrontal cortex (mPFC), insular cortex (IC) and rhomboid thalamic nucleus (Rh). Next, to examine the possible role of these brain regions in modulating sensitivity to alcohol, neuronal response to alcohol in rats trained to discriminate alcohol (1 g/kg, intragastric [IG]) vs...

BACKGROUND: Alcohol is the leading psychoactive substance consumed in France, with about 15 million regular consumers. The National institute on Alcohol Abuse and Alcoholism (NIAAA) considers alcohol abuse to be more than 14 units of alcohol a week for men and 7 units for women. The specific complication of alcoholism is the alcohol withdrawal syndrome. Its incidence reaches up to 30 % and its main complications are delirium tremens, restlessness, extended hospital stay, higher morbidity, and psychiatric and cognitive impairment...

BACKGROUND: Baclofen is increasingly prescribed for alcohol dependency. Subsequently, the risk of self-intoxication with this medicinal product is increasing. CASE DESCRIPTION: A 23-year-old man with a history of alcohol dependence was admitted to our hospital after self-intoxication with 2700 mg baclofen and 330 mg mirtazapine. Respiratory insufficiency as a result of the baclofen intoxication required intubation and admission to the ICU. During the first day, despite the use of sedatives, the patient became intermittently agitated and aggressive...

Baclofen is an agonist of peripheral and central B gamma-aminobutyric acid receptors, whose activation causes a myorelaxation and a powerfull depression of the central nervous system. Moreover, it has an action against addiction, in reducing craving. Commercialized since 1975 in France, to control muscle spasticity due to medullar affection or multiple sclerosis, it receives a temporary recommendation of use in march 2014, as a last-line adjuvant treatment in alcohol withdrawal. Beyond its therapeutic use, baclofen is involved in many self-induced intoxications...

Baclofen represented the hope of an effective treatment of addiction to alcohol, in a context where the therapeutic featuring agreement obtained modest results. The rise of baclofen has bypassed the usual academic procedures. There is a scientific rational prescription of baclofen. Its use opens up the prospect of using other agonists of GABAB to manage the craving.

Approximately 16-31% of patients in the intensive care unit (ICU) have an alcohol use disorder and are at risk for developing alcohol withdrawal syndrome (AWS). Patients admitted to the ICU with AWS have an increased hospital and ICU length of stay, longer duration of mechanical ventilation, higher costs, and increased mortality compared with those admitted without an alcohol-related disorder. Despite the high prevalence of AWS among ICU patients, no guidelines for the recognition or management of AWS or delirium tremens in the critically ill currently exist, leading to tremendous variability in clinical practice...

Baclofen, a gamma-aminobutyric acid-B agonist with muscle-relaxant properties, is widely used in patients with severe spasticity. In animals, baclofen has been shown to decrease respiratory drive. In humans, however, use of baclofen at the standard dose did not significantly impair sleep-disordered breathing in a susceptible population of snorers. Recently, there has been increasing interest in the role of baclofen for the treatment of alcohol dependence. We describe severe central sleep apnea (CSA) in four patients with none of the conditions commonly associated with CSA who were receiving chronic baclofen therapy for alcohol withdrawal...

Alcohol is one of the top three priority areas for public health worldwide. Alcohol is the second leading cause of liver disease, and 45-60% of cirrhosis deaths are alcohol related. In the United States it represents 30% of liver transplants and in Europe 50%. Twenty to 40% of cases of steatosis evolve into steatohepatitis, and l8-20% directly into liver cirrhosis; 20-40% of cases of steatohepatitis evolve into cirrhosis and 4-5% into hepatocellular carcinoma. This cascade of events takes 5 to 40 years. The temporal variability is related to the genetic pattern of the subject and the presence of associated risk factors...

Racemic baclofen [(±)-baclofen] has repeatedly been reported to suppress several -alcohol-motivated behaviors, including alcohol drinking and alcohol -self-administration, in rats and mice. Recent data suggested that baclofen may have bidirectional, stereospecific effects, with the more active enantiomer, R(+)-baclofen, suppressing alcohol intake and the less active enantiomer, S(-)-baclofen, stimulating alcohol intake in mice. The present study was designed to investigate whether this enantioselectivity of baclofen effects may also extend to the reinforcing properties of alcohol in rats...

The neurotrophin brain-derived neurotrophic factor (BDNF) has been suggested to be involved in the development and maintenance of addictive and other psychiatric disorders. Also, interactions of γ-aminobutyric acid (GABA)-ergic compounds and BDNF have been reported. The objective of this study was to investigate serum levels of BDNF over time in alcohol-dependent patients receiving individually titrated high-dose treatment (30-270mg/d) with the GABA-B receptor agonist baclofen or placebo for up to 20 weeks...

BACKGROUND: Alcohol withdrawal syndrome (AWS) is a distressing condition, generally controlled by benzodiazepines (BZD's). Baclofen, a gamma-aminobutyric acid-B (GABAB) agonist, has also shown promising results in controlling AWS. As there are few studies comparing the efficacy and tolerability of chlordiazepoxide with baclofen, the present study was taken up. The objective of this study was to compare efficacy and tolerability of baclofen with chlordiazepoxide in uncomplicated AWS. METHODS: Sixty subjects with uncomplicated AWS were randomized into two groups of 30 each, to receive baclofen (30 mg) or chlordiazepoxide (75 mg) in decremented fixed dose regime for 9 days...

Alcohol use disorders (AUD) cause significant morbidity and mortality worldwide, but pharmacological treatments for them are underused, despite evidence of efficacy. Acamprosate, naltrexone, nalmefene and disulfiram are all approved in one or more region for the treatment of AUD. Baclofen currently has a temporary indication in France. Safety considerations for using psychopharmacological treatments in this patient group include the impact of concurrent alcohol consumption at high levels; multiple physical comorbidities that may interfere with pharmacological effects, distribution and metabolism; and concomitant medication for the treatment of comorbid physical and psychiatric conditions...

The consequences of alcohol dependence concern serious health care, social and economic problems. The scope of many studies is to better understand mechanisms underlying alcohol addiction in order to work out new, more effective treatment strategies. Alcohol affects many neurotransmission systems within the brain. In general, acute alcohol enhances inhibitory transmission, up-regulating the GABAergic system and impairing glutamatergic function, therefore interfering the balance between excitatory and inhibitory synaptic inputs...

AIM: To characterize the profile of patients seeking baclofen treatment for alcohol dependence in France. METHOD: We compared retrospectively baclofen seekers and baclofen non-seekers within a cohort of consecutive outpatients with alcohol dependence who attended a first appointment for alcohol treatment at two French addiction centres between September 2012 and March 2014. We documented socio-demographic characteristics; comorbid psychiatric, addiction, alcohol dependence features; patients' initial drinking goal, and referral status; and treatment retention at 6 and 12 months...

INTRODUCTION: The off-label use of high-dose baclofen (HDB) for alcohol-dependence has recently spread. However, HDB has been associated with numerous reports of adverse events (AEs). Pharmacovigilance reporting is supposed to differentiate AEs from adverse drug reactions (ADRs), for which the causality of the drug is determined using validated methods. AREAS COVERED: Since 2010, we found 20 publications on baclofen-related AEs in alcohol dependence, in Medline-referenced journals or national pharmacovigilance reports...

UNLABELLED: In many human alcoholics, abstinence is self-imposed because of the negative consequences of excessive alcohol use, and relapse is often triggered by exposure to environmental contexts associated with prior alcohol drinking. We recently developed a rat model of this human condition in which we train alcohol-preferring P rats to self-administer alcohol in one context (A), punish the alcohol-reinforced responding in a different context (B), and then test for relapse to alcohol seeking in Contexts A and B without alcohol or shock...

Alcohol use disorder (AUD), as currently defined in the Diagnostic and Statistical Manual, 5th Edition (DSM-5), is a heterogeneous disorder stemming from a complex interaction of neurobiological, genetic, and environmental factors. As a result of this heterogeneity, there is no one treatment for AUD that will work for everyone. During the past 2 decades, efforts have been made to develop a menu of medications to give patients and clinicians more choices when seeking a therapy that is both effective and which has limited side effects...

Chronic or repeated stress increases alcohol consumption. The GABA-B agonist baclofen decreases alcohol consumption and may be most effective for individuals with comorbid anxiety/stress disorders. The present study sought to determine if baclofen blocks stress-induced increases in ethanol self-administration as modeled by repeated yohimbine injections in rats. Rats were trained to respond for 15% w/v ethanol in operant chambers using a method that applies neither water deprivation nor saccharin/sucrose fading...

Alcohol consumption and hepatitis C virus (HCV) infection have a synergic hepatotoxic effect, and the coexistence of these factors increases the risk of advanced liver disease. The main mechanisms of this effect are increased viral replication and altered immune response, although genetic predisposition may also play an important role. Traditionally, HCV prevalence has been considered to be higher (up to 50%) in alcoholic patients than in the general population. However, the presence of advanced alcoholic liver disease (ALD) or intravenous drug use (IDU) may have confounded the results of previous studies, and the real prevalence of HCV infection in alcoholic patients without ALD or prior IDU has been shown to be lower...
