Nalmefene, a mu- and delta-opioid receptor (MOR, DOR) antagonist and a partial kappa-opioid receptor (KOR) agonist, is approved in the European Union and other countries for the reduction of alcohol consumption in alcohol dependent patients with a high drinking risk level according to WHO ("target population"). This review presents an overview of nalmefene׳s pharmacology, its mechanisms of action and a meta-analysis on its efficacy in reducing alcohol consumption. The review was based on a systematic search of the literature...

Nalmefene was the first treatment approved by the European Medicines Agency for reducing alcohol consumption in adult patients with alcohol dependence. It is often presented as a paradigm shift in therapeutics, but major issues limit the interpretation of the evidence supporting its use. The randomised trials submitted provided no evidence of harm reduction, the differences on consumption outcomes were of questionable clinical relevance, the target population was defined a posteriori and the drug was compared to a placebo although naltrexone was already used off-label...

The development of pharmacotherapeutics that reduce relapse to alcohol drinking in patients with alcohol dependence is of considerable research interest. Preclinical data support a role for nucleus accumbens (NAc) κ opioid receptors (KOR) in chronic intermittent ethanol (CIE) exposure-induced increases in ethanol intake. Nalmefene, a high-affinity KOR partial agonist, reduces drinking in at-risk patients and relapse drinking in rodents, potentially due to its effects on NAc KORs. However, the effects of nalmefene on accumbal dopamine transmission and KOR function are poorly understood...

BACKGROUND AND OBJECTIVE: When modelling the pathophysiology of a disease, it is important to select a modelling approach that can adequately replicate its course. The objective of this paper was to compare the outcomes obtained by the Markov and discrete-time microsimulation modelling approaches using nalmefene clinical trial data. METHODS: Markov and microsimulation modelling approaches assessing alcohol dependence treatment with psychosocial support with or without nalmefene were compared in terms of the modelled evolution of patients' alcohol consumption and the resulting occurrence of alcohol-attributable harmful events over 1 year...

BACKGROUND: Acamprosate, disulfiram (DIS), naltrexone and nalmefene can be used in treating alcohol use disorders. The drugs are, however, underutilized. METHODS: In this survey of marketing status and perceived efficacy, member societies of the European federation for addiction societies were asked to report on the status of these drugs in their country. Results were obtained from 20 European countries showing that the drugs were registered in most countries. RESULTS AND CONCLUSION: The drugs were mentioned in guidelines in approximately half and were partially or fully reimbursed in half to two-thirds countries...

BACKGROUND: Alcohol dependence causes considerable harm to patients. Treatment with nalmefene, aiming to reduce consumption rather than maintain complete abstinence, has been licensed based on trials demonstrating a reduction in total alcohol consumption and heavy drinking days. Relating these trial outcomes to harmful events avoided is important to demonstrate the clinical relevance of nalmefene treatment. METHODS: A predictive microsimulation model was developed to compare nalmefene plus brief psychosocial intervention (BRENDA) versus placebo plus BRENDA for the treatment of patients with alcohol dependence and a high or very high drinking risk level based on three pooled clinical trials...

BACKGROUND AND AIMS: Nalmefene has been approved in Europe for the treatment of alcohol dependence and subsequently recommended by the UK National Institute for Health and Care Excellence (NICE). This study examines critically the evidence base underpinning both decisions and the issues arising. METHODS: Published studies of nalmefene were identified through a systematic search, with documents from the European Medicines Agency, the NICE appraisal and public clinical trial registries also examined to identify methodological issues...

BACKGROUND AND PURPOSE: The opioid antagonist nalmefene (selincro®) was approved for alcohol-related disorders by the European Medicines Agency in 2013. However, there have been no studies regarding the effectiveness of nalmefene when alcohol is used in combination with cocaine. EXPERIMENTAL APPROACH: Using operant alcohol self-administration in Wistar rats and qRT-PCR, we evaluated (i) the dose-response curve for s.c. and p.o. nalmefene; (ii) the effects of nalmefene with increasing concentrations of alcohol; (iii) the efficacy of nalmefene on cocaine-potentiated alcohol responding; and (iv) the gene expression profiles of histone deacetylases (Hdac1-11) in peripheral blood in vivo and in the prefrontal cortex, heart, liver and kidney post mortem...

Nalmefene is an opioid antagonist which as a once-a-day tablet formulation has recently been approved for reducing ethanol intake in alcoholic subjects. In order to address the compliance issue in this patient population, a number of potential nalmefene prodrugs were synthesized with the aim of providing a formulation that could provide plasma drug concentrations in the region of 0.5-1.0ng/mL for a one-month period when dosed intramuscular to dogs or minipigs. In an initial series of studies, three different lipophilic nalmefene derivatives were evaluated: the palmitate (C16), the octadecyl glutarate diester (C18-C5) and the decyl carbamate (CB10)...

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...

REVIEW
Agnieszka Michalak, Grazyna Biała
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...

Opioid antagonist treatments reduce alcohol drinking in rodent models and in alcohol-dependent patients, with variable efficacy across different studies. These treatments may suffer from the development of tolerance and opioid receptor supersensitivity, as suggested by preclinical models showing activation of these processes during and after subchronic high-dose administration of the short-acting opioid antagonist naloxone. In the present study, we compared equipotent low and moderate daily doses of naltrexone and nalmefene, two opioid antagonists in the clinical practice for treatment of alcoholism...

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...

AIM: To evaluate costs and health outcomes of nalmefene plus psychosocial support, compared with psychosocial intervention alone, for reducing alcohol consumption in alcohol-dependent patients, specifically focusing on societal costs related to productivity losses and crime. METHODS: A Markov model was constructed to model costs and health outcomes of the treatments over 5 years. Analyses were conducted for nalmefene's licensed population: adults with both alcohol dependence and high or very high drinking-risk levels (DRLs) who do not require immediate detoxification and who have high or very high DRLs after initial assessment...

The treatment of alcohol use disorder still remains a challenge. The efficacy of the combined pharmacological treatment for alcohol use disorder has been widely investigated with controversial results. The aim of our case series was to investigate the effect of nalmefene in patients not responding to sodium oxybate therapy. We describe seven cases of consecutive patients affected by alcohol use disorder, and treated with sodium oxybate (50 mg/kg per day) who did not achieve complete alcohol abstinence after at least one month of pharmacological treatment...
