[PMID: 39300991 PMCID: PMC11408456 DOI: 10.1007/s41105-024-00544-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2024] [Accepted: 07/02/2024] [Indexed: 09/22/2024]
Abstract
Substance use disorders (SUDs) are associated with profound sleep disturbances, including insomnia, sleep fragmentation, and circadian rhythm dysfunction resulting in serious mental and physical consequences. This minireview presents an overview of the neurocircuitry underlying sleep disturbances in SUDs and elaborates on treatment options with emphasis on alcohol use disorder (AUD) and opioid use disorder (OUD). A PubMed, Embase, CINAHL Plus, Cochrane, and Scopus search were conducted using sleep- and AUD/OUD related keywords from January 1st, 2000, to January 31st, 2023, with preferences for recent publications and randomized-controlled trials. A bidirectional relationship exists between insomnia and addiction with the status of each condition impacting the other in dictating clinical outcome. Existing evidence points to a resurgence of insomnia during detoxification, and unless treated satisfactorily, insomnia may lead to relapse. The discussion summarizes the strengths and limitations of cognitive behavioral therapy and pharmacological treatment for insomnia in SUDs covering evidence from both animal and clinical studies. The assumption of reestablishing normal sleep patterns by attaining and maintaining sobriety is misguided. Comorbid insomnia in patients with SUDs should be approached as an independent condition that requires its own treatment. Future clinical trials are needed with the aim of providing a resource for guiding clinical management of the many patients with insomnia and SUD.

Abstract
Alcohol-associated liver disease (ALD)-related morbidity and mortality are rising in the United States. Although effective medications and behavioral interventions are available for the treatment of patients with alcohol use disorder (AUD), patients with ALD are profoundly undertreated for AUD. This article reviews the management of AUD in patients with ALD, with a focus on appropriate screening and diagnosis, management of alcohol withdrawal syndrome, pharmacotherapy for AUD, alcohol biomarkers, and behavioral interventions. Expanding access to AUD treatment is imperative for improving health outcomes in patients with ALD.

Abstract
Alcohol use disorder (AUD) rates have risen dramatically in the United States, resulting in increasing rates of alcohol-associated liver disease (ALD), but many patients struggle to access alcohol use treatment. AUD treatment improves outcomes, including mortality, and represents the most urgent means by which care can be improved for those with liver disease (including ALD and others) and AUD. AUD care for those with liver disease involves 3 steps: detecting alcohol use, diagnosing AUD, and directing patients to alcohol treatment. Detecting alcohol use can involve questioning during the clinical interview, the use of standardized alcohol use surveys, and alcohol biomarkers. Identifying and diagnosing AUD are interview-based processes that should ideally be performed by a trained addiction professional, but nonaddiction clinicians can use surveys to determine the severity of hazardous drinking. Referral to formal AUD treatment should be made, especially where more severe AUD is suspected or identified. Therapeutic modalities are numerous and include different forms of one-on-one psychotherapy, such as motivational enhancement therapy or cognitive behavior therapy, group therapy, community mutual aid societies (such as Alcoholics Anonymous), inpatient addiction treatment, and relapse prevention medications. Finally, integrated care approaches that build strong relationships between addiction professionals and hepatologists or medical providers caring for those with liver disease are crucial to improving care for this population.

Abstract
Among individuals with alcohol use disorder (AUD), it is estimated that the majority suffer from persistent sleep disturbances for which few candidate medications are available. Our aim wass to critically review the potential for cannabidiol (CBD) as a treatment for AUD-induced sleep disturbance. As context, notable side effects and abuse liability for existing medications for AUD-induced sleep disturbance reduce their clinical utility. CBD modulation of the endocannabinoid system and favorable safety profile have generated substantial interest in its potential therapeutic use for various medical conditions. A number of preclinical and clinical studies suggest promise for CBD in restoring the normal sleep-wake cycle and in enhancing sleep quality in patients diagnosed with AUD. Based on its pharmacology and the existing literature, albeit primarily preclinical and indirect, CBD is a credible candidate to address alcohol-induced sleep disturbance. Well-designed RCTs will be necessary to test its potential in managing this challenging feature of AUD.

Abstract
Rising rates of alcohol use disorder (AUD) combined with increases in alcohol-related liver disease (ALD) and other liver disease have resulted in the need to develop alcohol management strategies at all levels of patient care. For those with pre-existing liver disease, whether ALD or others, attention to alcohol use treatment and abstinence becomes critical to avoiding worsening liver-related consequences. Modalities to help patients reduce or stop alcohol include screening/brief intervention/referral to treatment, various therapeutic modalities including cognitive behavioral therapy, motivational enhancement therapy and 12-step facilitation, and alcohol relapse prevention medications. Harm reduction approaches versus total abstinence may be considered, but for those with existing ALD, particularly advanced ALD (cirrhosis or acute alcoholic hepatitis), total abstinence from alcohol is the recommendation, given clear data that ongoing alcohol use worsens mortality and liver-related morbidity. For certain populations, alcohol cessation is even more critically important. For those with hepatitis C or NAFLD, alcohol use accelerates negative liver-related outcomes. In women, alcohol use accelerates liver damage and results in worsened liver-related mortality. Efforts to integrate AUD and liver disease care are urgently needed and can occur at several levels, with establishment of multidisciplinary ALD clinics for fully integrated co-management as an important goal.

Abstract
Alcohol use disorder (AUD) is a common condition that develops on the background of heavy alcohol use and is characterised by the loss of control over alcohol use and a compulsion to use alcohol, often despite negative consequences. AUD is a leading cause for the resumption of alcohol use in patients with alcoholic liver disease (ALD) after treatment. Hence it is essential to screen all patients with ALD for the presence of AUD. Screening tools such as alcohol use disorders identification test (AUDIT) and AUDIT-C are used, following which the diagnosis and severity of AUD are determined using DSM-5 criteria. The management of AUD in patients with ALD is best carried out using an integrated approach involving psychiatrists and gastroenterologists/hepatologists. The treatment most often involves a combination of pharmacotherapy and psychosocial interventions which try to achieve and maintain abstinence. Although, there is limited evidence, Baclofen is the first line pharmacological agent for long-term management of AUD in patients with ALD. Intensive psychological interventions such as motivation enhancement therapy and cognitive behavioural therapy are also seen to be beneficial. Treatment retention and follow-up are vital and can positively influence outcomes.

Abstract
INTRODUCTION In the last decades, many medications have been tested for the treatment of Alcohol Use Disorder (AUD). Among them, disulfiram, acamprosate, naltrexone, nalmefene, sodium oxybate and baclofen have been approved in different countries, with different specific indications. Topiramate is not approved for the treatment of AUD, however, it is suggested as a therapeutic option by the American Psychiatric Association for patients who do not tolerate or respond to approved therapies. AREAS COVERED In this narrative review we have analyzed the main studies available in literature, investigating the efficacy and safety of these medications, distinguishing whether they were oriented towards abstinence or not. Randomized controlled studies, analyzing larger populations for longer periods were the main focus of our analysis. CONCLUSIONS The medications currently available for the treatment of AUD are quite effective, yet further progress can still be achieved through the personalized strategies. Also, these medications are still markedly underutilized in clinical practice and many patients do not have access to specialized treatment.

Abstract
BACKGROUND Sleep disturbances and disorders are a common and sometimes recalcitrant problem in persons recovering from substance use disorders (SUDs). As such, several randomized-controlled trials (RCTs) have been conducted to address sleep disturbances in a variety of SUD subpopulations and clinical scenarios. The goal of this systematic review was to collate patient-reported sleep outcomes used in past SUD-related RCTs to provide guidance for future sleep research in persons with SUDs. METHODS This systematic review was registered in the International Prospective Register of Systematic Reviews (PROSPERO) on May 7th, 2020 (CRD42020182004). Studies were included if they were peer-reviewed manuscripts describing RCTs in an SUD population. RESULTS The initial search yielded 13,403 candidate articles, and 76 met a priori criteria and were included in this review. Thirty-five (46.1%) assessed sleep as a primary outcome (i.e., sleep improvement was the primary goal of the research) and 41 (53.9%) assessed sleep as a secondary outcome (i.e., sleep improvement was an important outcome, but not the primary outcome). The most commonly used measures included the Pittsburgh Sleep Quality Index, the Insomnia Severity Index, and sleep diaries. However, multiple additional sleep assessments were also used, including visual analogue and Likert scales. CONCLUSIONS The field of addiction medicine would benefit from a streamlined approach in assessing patient-reported sleep in RCTs, including commonly used and validated assessments of sleep quality, inserting daily or repeated measures into RCTs, and including questionnaires that assess clinically relevant insomnia or other sleep disorders.

Abstract
Alcohol use disorder (AUD) is one of the main causes of global death and disability. The liver represents the main target of alcohol damage, and alcohol-associated liver disease (ALD) represents the first cause of liver cirrhosis in Western countries. Alcohol abstinence is the main goal of treatment in AUD patients with ALD, as treatments for ALD are less effective when drinking continues. Moreover, the persistence of alcohol consumption is associated with higher mortality, increased need for liver transplantation, and graft loss. The most effective treatment for AUD is the combination of psychosocial interventions, pharmacological therapy, and medical management. However, the effectiveness of these treatments in patients with ALD is doubtful even because AUD patients with ALD are usually excluded from pharmacological trials due to concerns on liver safety. This narrative review will discuss the treatment options for AUD-ALD patients focusing on controversies in pharmacological therapy.

Abstract
BACKGROUND AND OBJECTIVE Topiramate has been approved by the US Food and Drug Administration for the treatment of epilepsy since the 1990s, and it has also been used off-label in the treatment of many types of addictive disorders. To date, no systematic review has embraced the entire field of addiction, both substance use and behavioral addictions, including eating disorders, to compare topiramate-based protocols and the related level of evidence in each addictive disorder. Our objective is to fill this gap. METHODS A systematic search was conducted using the MEDLINE, PsycINFO, and Cochrane databases without a date or language limit. All trials and meta-analyses assessing the efficacy of topiramate in alcohol use disorder; cocaine use disorder; methamphetamine, nicotine, cannabis, opiate, and benzodiazepine use disorders; binge eating disorder; bulimia; and pathological gambling were analyzed. The quality of the studies was rated using the Cochrane Risk-of-Bias tool for randomized trials (ROB-2), the Risk of Bias In Nonrandomized Studies (ROBINS-I), or the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist, depending on the study design. Safety features were assessed based on a wider non-systematic review. RESULTS Sixty-two articles were reviewed. Treatment protocols were relatively homogenous across addictive disorders, with slow dose titration schemes and a maximum dose range of 200-400 mg per day. The most supportive evidence for topiramate efficacy was found in alcohol use disorder for drinking reduction parameters only. To a lesser extent, topiramate could be a promising therapeutic option for binge eating disorder and cocaine use disorder. Evidence was weak for other addictive disorders. No major tolerability issues were found, provided that basic safety rules were followed. Adverse drug reactions could lead to early treatment discontinuation. DISCUSSION Though off-label, addiction specialists should consider topiramate as a second-line option for drinking reduction in alcohol use disorder, as well as for binge eating disorder or cocaine use disorder.

Abstract
BACKGROUND HIV, heavy drinking, and smoking are all pro-inflammatory and increase risk for coronary heart disease (CHD). Interventions that reduce alcohol use, smoking, or both in HIV-positive people could lower inflammation, CHD and death risk. Varenicline and cytisine are proven therapies for smoking cessation and may also reduce alcohol consumption. The comparative efficacy of varenicline and cytisine to reduce alcohol consumption has not been tested, nor has their comparative effectiveness been reported for smoking. OBJECTIVE This paper describes the protocol of the Studying Partial agonists for Ethanol and Tobacco Elimination in Russians with HIV (St PETER HIV), a four-arm parallel-group randomized controlled trial comparing effects of varenicline, cytisine, and nicotine replacement therapy (NRT). METHODS The study is recruiting four hundred HIV-positive heavy drinking smokers interested in cutting down on alcohol and/or tobacco in St. Petersburg, Russia. Participants are randomly assigned to receive either active varenicline + NRT placebo, varenicline placebo + active NRT, active cytisine + NRT placebo, cytisine placebo + active NRT. All participants receive evidence-based counseling for alcohol and tobacco use, one active medication, and one placebo. Outcomes are: 1) % heavy drinking days in the past month (primary study outcome at three months) and alcohol craving; 2) cigarettes per day (primary smoking outcome at 3 months) and 7-day point prevalence abstinence and; 3) inflammation, CHD risk, and mortality risk. CONCLUSION St PETER HIV addresses the paucity of randomized controlled trial data to guide treatment of alcohol consumption and smoking in HIV-positive heavy drinking smokers.

Abstract
Pathologic alcohol use affects more than 2 billion people and accounts for nearly 6% of all deaths worldwide. There are three medications approved for the treatment of alcohol use disorder by the US Food and Drug Administration (FDA): disulfiram, naltrexone (oral and long-acting injectable), and acamprosate. Of growing interest is the use of anticonvulsants for the treatment of alcohol use disorder, although currently none are FDA approved for this indication. Baclofen, a γ-aminobutyric acid B receptor agonist used for spasticity and pain, received temporary approval for alcohol use disorder in France. Despite effective pharmacotherapies, less than 9% of patients who undergo any form of alcohol use disorder treatment receive pharmacotherapies. Current evidence does not support the use of pharmacogenetic testing for treatment individualization. The objective of this review is to provide knowledge on practice parameters for evidenced-based pharmacologic treatment approaches in patients with alcohol use disorder.

Abstract
: Topiramate is a non-benzodiazepine anticonvulsant medication with multi-faceted pharmacologic action. It has emerged as an efficacious pharmacotherapeutic option for the treatment of addiction, especially alcohol use disorder (AUD). We present a broad narrative review of the putative mechanism of action and clinical utility of topiramate with regard to AUD and other substance use disorders. Collective evidence suggests topiramate is an effective treatment option in AUD, with notable efficacy in reducing harmful drinking patterns in AUD. Though not currently approved by the United States Food and Drug Administration for the indication of AUD, topiramate should be considered as a pharmacological treatment option with high utility among AUD patients. Early pharmacogenetic studies raise the intriguing possibility of identifying patients likely to respond to topiramate using genetic testing, and initial studies show that topiramate may also be useful in treating cocaine use disorder, smoking cessation and behavioral addictions. However, further research is needed in all these areas.

Abstract
Non-alcoholic fatty liver disease (NAFLD) is a common comorbidity in individuals with obesity. Although multiple pharmacotherapeutics are in development, currently there are limited strategies specifically targeting NAFLD. This systematic review summarizes the existing literature on hepatic effects of medications used for weight loss. Glucagon-like peptide 1 (GLP-1) agonists are the best-studied in this regard, and evidence consistently demonstrates reduction in liver fat content, sometimes accompanied by improvements in histological features of steatohepatitis and reductions in serum markers of hepatic injury such as alanine aminotransferase (ALT). It remains unclear whether these benefits are independent of the weight loss caused by these agents. Literature is limited regarding effects of orlistat, but a small number of reports suggest that orlistat reduces liver fat content and improves histologic features of NASH, benefits which may also be driven primarily by weight loss. A sizeable body of literature on hepatic effects of metformin yields mixed results, with a probability of modest benefit, but no consistent signal for strong benefit. There are insufficient data on hepatic effects of topiramate, phentermine, naltrexone, bupropion, and lorcaserin. Finally, a few studies to date suggest that sodium-glucose co-transporter-2 (SGLT2) inhibitors may reduce liver fat content and cause modest reductions in ALT, but further study is needed to better characterize these effects. Based on available data, GLP-1 agonists have the strongest evidence base demonstrating beneficial effects on NAFLD, but it is not clear if any weight loss medication has effects on NAFLD superior to those of nutritional modification and exercise alone.

Abstract
Alcohol use disorder is the most common cause of advanced liver disease in the Western world. Diagnosis of alcohol use disorder can be difficult because patients with liver disease tend to deny alcohol intake for the fear of being excluded from treatment and because available biomarkers of alcohol intake have poor specificity in these patients. Alcohol abstinence is the cornerstone of the therapy in these patients. However, pharmacological treatments for alcohol use disorders have not been formally tested in patients with advanced liver disease, except for baclofen. Psychosocial intervention became crucial in these patients considering the limited pharmacological choice. However, psychosocial approach and an appropriate team to manage these patients are not still well defined. In this review, we critically discuss the diagnosis and the management of alcohol use disorder in patients with liver disease.

Abstract
The development of alcohol use disorder (AUD) involves binge or heavy drinking to high levels of intoxication that leads to compulsive intake, the loss of control in limiting intake, and a negative emotional state when alcohol is removed. This cascade of events occurs over an extended period within a three-stage cycle: binge/intoxication, withdrawal/negative affect, and preoccupation/anticipation. These three heuristic stages map onto the dysregulation of functional domains of incentive salience/habits, negative emotional states, and executive function, mediated by the basal ganglia, extended amygdala, and frontal cortex, respectively. Sleep disturbances, alterations of sleep architecture, and the development of insomnia are ubiquitous in AUD and also map onto the three stages of the addiction cycle. During the binge/intoxication stage, alcohol intoxication leads to a faster sleep onset, but sleep quality is poor relative to nights when no alcohol is consumed. The reduction of sleep onset latency and increase in wakefulness later in the night may be related to the acute effects of alcohol on GABAergic systems that are associated with sleep regulation and the effects on brain incentive salience systems, such as dopamine. During the withdrawal/negative affect stage, there is a decrease in slow-wave sleep and some limited recovery in REM sleep when individuals with AUD stop drinking. Limited recovery of sleep disturbances is seen in AUD within the first 30 days of abstinence. The effects of withdrawal on sleep may be related to the loss of alcohol as a positive allosteric modulator of GABAA receptors, a decrease in dopamine function, and the overactivation of stress neuromodulators, including hypocretin/orexin, norepinephrine, corticotropin-releasing factor, and cytokines. During the preoccupation/anticipation stage, individuals with AUD who are abstinent long-term present persistent sleep disturbances, including a longer latency to fall asleep, more time awake during the night, a decrease in slow-wave sleep, decreases in delta electroencephalogram power and evoked delta activity, and an increase in REM sleep. Glutamatergic system dysregulation that is observed in AUD is a likely substrate for some of these persistent sleep disturbances. Sleep pathology contributes to AUD pathology, and vice versa, possibly as a feed-forward drive to an unrecognized allostatic load that drives the addiction process.

Abstract
Substance use disorder is a highly prevalent condition, leading to significant morbidity, mortality, and burden on the health care system. Substance use disorders are overrepresented among individuals with a mental illness. The term "dual diagnosis" was introduced by the World Health Organization in the mid-1990s and refers to the co-occurrence of a substance use disorder with mental illness-a more recently used term is "co-occurring disorders." In the past decade, substantial progress has been made toward expanding psychotherapeutic and pharmacotherapeutic treatments for treating co-occurring disorders. Yet management remains a challenge among clinicians and has been a source of confusion and considerable controversy. This review describes the epidemiology and treatment of co-occurring disorders, with a focus on major depressive disorder, anxiety disorders, and attention-deficit hyperactivity disorder. Substance use may make diagnosis of the underlying psychiatric condition difficult, and a period of abstinence may be necessary. Findings from efficacy studies of medications used to treat co-occurring disorders are reviewed, as are results of preliminary studies of newer treatments, such as topiramate, ketamine, noninvasive brain stimulation, and deep brain stimulation. Treatment recommendations that combine medications and psychosocial interventions are summarized.

Abstract
Aims The goal of this study was to evaluate the efficacy of topiramate up to 200 mg/day and of aripiprazole up to 15 mg/day, alone and combined, in reducing alcohol-related outcomes in a human laboratory study. Method This was a 5 week, between-subject, double-blind, placebo-controlled human laboratory study with topiramate [0 mg/day (placebo), 100 mg/day, 200 mg/day] and aripiprazole [0 mg/day (placebo), 7.5 mg/day, 15 mg/day] in 90 non-treatment seeking, heavy drinking, alcohol-dependent individuals. Main outcomes were the efficacy of 200 mg/day topiramate and 15 mg/day aripiprazole, alone and combined, in reducing drinks consumed during an alcohol self-administration procedure (human laboratory phase) and while receiving the study medications prior to the laboratory session (naturalistic drinking phase). Other outcomes in the laboratory phase included alcohol craving, and alcohol biphasic effects. Results In the human laboratory phase, topiramate 200 mg/day reduced alcohol craving [**P < 0.01] and amplified alcohol-induced stimulation [*P < 0.05], but did not reduce the number of drinks consumed. Topiramate 200 mg/day was also effective in reducing drinking days [*P < 0.05], and alcohol craving [*P < 0.05], in the naturalistic drinking phase. No significant findings were found for aripiprazole for any of the outcomes analyzed. Conclusion Participants receiving 200 mg/day topiramate reported reduced alcohol drinking and craving, and increased alcohol-related stimulation. These findings provide further support for the role of topiramate as a pharmacological treatment for AUD. ClinicalTrial.gov Identifier NCT00884884. Short Summary This study tested topiramate and aripiprazole alone and in combination. The results replicate past findings and suggest that topiramate may be an effective treatment for alcohol use disorder. The present results suggest that the combination of topiramate and aripiprazole do not warrant further evaluation.

Abstract
BACKGROUND A minority of individuals with problematic alcohol use effectively seek help. Moreover, dropouts from care are not uncommon. It remains a major concern for health professionals, as adherence to treatment is significantly associated with better physical and psychological outcomes. OBJECTIVES The main aim of this research was to assess what factors could distinguish patients with problematic alcohol use who dropped out from those who did not. METHODS The sample included 150 patients followed-up in an outpatient treatment center in France for a problematic alcohol use. Two measurement times were planned: at the first appointment and after six month of treatment. A large set of individual, environmental and institutional variables were considered to compare both subgroups. RESULTS Patients who dropped out mostly differ from patients who did not with a higher level of alcohol-related problems, ambivalence, inclinations to use the substance, number of missed appointments. Significant results were also observed regarding a lower time gap between the first contact with the center and the first appointment, as well as the season of the last appointment. CONCLUSIONS Tailored motivational interventions could be offered to ambivalent patients, especially during the beginning of the treatment and some significant periods of the year. A particular focus should be brought on patients presenting such profiles in terms of level of alcohol problems, inclinations to drink and motivation to change. Overall, the study provides elements to better understand what may bring one patient to drop out of the treatment, and to improve the continuity of care.

Abstract
Alcohol use disorder is a common, destructive, and undertreated disease. As understanding of alcohol use disorder has evolved, so has our ability to manage patients with pharmacotherapeutic agents in addition to nondrug therapy, including various counseling strategies. Providers now have a myriad of medications, both approved and not approved by the US Food and Drug Administration, to choose from and can personalize care based on treatment goals, comorbidities, drug interactions, and drug availability. This review explores these treatment options and offers the prescriber practical advice regarding when each option may or may not be appropriate for a specific patient.

Abstract
Inherited genetic variants contribute to risk factors for developing an alcohol use disorder, and polymorphisms may inform precision medicine strategies for treating alcohol addiction. Targeting genetic mutations linked to alcohol phenotypes has provided promising initial evidence for reducing relapse rates in alcoholics. Although successful in some studies, there are conflicting findings and the reports of adverse effects may ultimately limit their clinical utility, suggesting that novel pharmacogenetic targets are necessary to advance precision medicine approaches. Here, we describe promising novel genetic variants derived from preclinical models of alcohol consumption and dependence that may uncover disease mechanisms that drive uncontrolled drinking and identify novel pharmacogenetic targets that facilitate therapeutic intervention for the treatment of alcohol use disorder.

Abstract
Insomnia in patients with alcohol dependence has increasingly become a target of treatment due to its prevalence, persistence, and associations with relapse and suicidal thoughts, as well as randomized controlled studies demonstrating efficacy with behavior therapies and non-addictive medications. This article focuses on assessing and treating insomnia that persists despite 4 or more weeks of sobriety in alcohol-dependent adults. Selecting among the various options for treatment follows a comprehensive assessment of insomnia and its multifactorial causes. In addition to chronic, heavy alcohol consumption and its effects on sleep regulatory systems, contributing factors include premorbid insomnia; co-occurring medical, psychiatric, and other sleep disorders; use of other substances and medications; stress; environmental factors; and inadequate sleep hygiene. The assessment makes use of history, rating scales, and sleep diaries as well as physical, mental status, and laboratory examinations to rule out these factors. Polysomnography is indicated when another sleep disorder is suspected, such as sleep apnea or periodic limb movement disorder, or when insomnia is resistant to treatment. Sobriety remains a necessary, first-line treatment for insomnia, and most patients will have some improvement. If insomnia-specific treatment is needed, then brief behavioral therapies are the treatment of choice, because they have shown long-lasting benefit without worsening of drinking outcomes. Medications work faster, but they generally work only as long as they are taken. Melatonin agonists; sedating antidepressants, anticonvulsants, and antipsychotics; and benzodiazepine receptor agonists each have their benefits and risks, which must be weighed and monitored to optimize outcomes. Some relapse prevention medications may also have sleep-promoting activity. Although it is assumed that treatment for insomnia will help prevent relapse, this has not been firmly established. Therefore, insomnia and alcohol dependence might be best thought of as co-occurring disorders, each of which requires its own treatment.

Pharmacotherapy for alcohol dependence: A stratified approach. Pharmacol Ther 2015; 153:10-24.

Abstract
Alcohol dependence is a common disorder in many societies worldwide, and remains difficult to identify and treat. It is also a risk factor for many secondary non-communicable diseases. Pharmacotherapy is one available treatment option, but appears to be underutilised in practice. Major barriers to use of medications in this area include lack of clinical guidance and questionable efficacy. However, for each medication there appears to be a subpopulation that responds positively, and understanding the moderating factors to treatment efficacy is an important research goal. Thus, this review provides a narrative regarding potential stratification techniques in pharmacological treatment of alcohol dependence, with a specific focus on typologies and pharmacogenetics. In addition, we discuss the basic background of stratified medicine and recent studies on genetic predisposition to alcohol dependence. A growing repository of data exists for both approved and non-approved pharmacotherapies, but failure to replicate findings, inadequate sample sizes, and insufficient funding has resulted in a translational gap. Implementing evidence-based stratified/personalised therapy and identifying new therapeutic agents may lead to improved clinical outcomes and reduced financial burden. Despite some promising findings to date, much work is still required.

Abstract
To date, a limited number of pharmacological agents exist to treat alcohol use disorders (AUDs), and there is growing interest in new therapeutic tools. In this framework, topiramate may represent a useful treatment option, although its use is not yet approved for AUDs. The main focus of this review is to discuss all the existing data supporting the use of topiramate in AUDs, with an emphasis on the most recent and relevant clinical implications. In addition, the profile of the alcoholic patient who may benefit more from the use of topiramate is outlined. In this regard, the authors conducted a PubMed search of clinical human studies published in English using the following key words: topiramate alcohol dependence, topiramate alcohol withdrawal and topiramate alcoholism. The evidence suggests that topiramate could be an effective treatment option for the management of AUDs, while there are limited results for its use to treat alcohol withdrawal syndrome. In particular, topiramate shows a greater beneficial effect in subjects with a typology of craving characterised by drinking obsessions and automaticity of drinking. Topiramate, within the dosage range of 75-300 mg/day, could be considered as a first-line treatment option for the management of AUDs. Its use appears to be safe and well-tolerated, especially in light of very recent findings.

Abstract
Alcoholic patients suffer from harmful allostatic neuroplastic changes in the brain causing an acute withdrawal syndrome upon cessation of drinking followed by a protracted abstinence syndrome and an increased risk of relapse to heavy drinking. Benzodiazepines have long been the treatment of choice for detoxifying patients and managing alcohol withdrawal syndrome (AWS). Non-benzodiazepine anticonvulsants (NBACs) are increasingly being used both for alcohol withdrawal management and for ongoing outpatient treatment of alcohol dependence, with the goal of either abstinence or harm reduction. This expert narrative review summarizes the scientific basis and clinical evidence supporting the use of NBACs in treating AWS and for reducing harmful drinking patterns. There is less evidence in support of NBAC therapy for AWS, with few placebo-controlled trials. Carbamazepine and gabapentin appear to be the most promising adjunctive treatments for AWS, and they may be useful as monotherapy in select cases, especially in outpatient settings and for the treatment of mild-to-moderate low-risk patients with the AWS. The body of evidence supporting the use of the NBACs for reducing harmful drinking in the outpatient setting is stronger. Topiramate appears to have a robust effect on reducing harmful drinking in alcoholics. Gabapentin is a potentially efficacious treatment for reducing the risk of relapse to harmful drinking patterns in outpatient management of alcoholism. Gabapentin's ease of use, rapid titration, good tolerability, and efficacy in both the withdrawal and chronic phases of treatment make it particularly appealing. In summary, several NBACs appear to be beneficial in treating AWS and alcohol use disorders.

Abstract
The anticonvulsant topiramate not only decreases ethanol consumption in alcohol dependence (AD) but also may produce several adverse events including cognitive impairment. Zonisamide is a structurally related anticonvulsant that is a promising agent for the treatment of AD and may have greater tolerability than topiramate. This study evaluated the effects of zonisamide (400 mg/d) on alcohol consumption and its neurotoxic effects in subjects with AD. A double-blind placebo-controlled clinical trial was conducted using 2 comparator anticonvulsant drugs, topiramate (300 mg/d) and levetiracetam (2000 mg/d), which does not impair cognition. Study medications were administered for 14 weeks, including a 2-week taper period. Medication adherence was facilitated using Brief Behavioral Compliance Enhancement Treatment. The neurotoxicity of the study drugs was assessed using neuropsychological tests and the AB-Neurotoxicity Scale. Compared with placebo, both zonisamide and topiramate produced significant reductions in the drinks consumed per day, percent days drinking, and percent days heavy drinking. Only the percent days heavy drinking was significantly decreased in the levetiracetam group. The topiramate cell was the only group that had a significant increase on the mental slowing subscale of the Neurotoxicity Scale compared with placebo at study weeks 11 and 12. Topiramate and zonisamide both produced modest reductions in verbal fluency and working memory. These findings indicate that zonisamide may have efficacy in the treatment of AD, with effect sizes similar to topiramate. Both of these drugs produced similar patterns of cognitive impairment, although only the topiramate group reported significant increases in mental slowing.

Abstract
Using retrospective reports obtained during treatment visits in 138 heavy drinkers, we found that topiramate's reduction of heavy drinking was moderated by a polymorphism (rs2832407) in GRIK1, which encodes the GluK1 kainate subunit (Kranzler et al., 2014a). A subsequent analysis of that 12-week topiramate treatment trial showed similar effects of medication and genotype on daily drinking reports obtained via interactive voice response technology (IVR; Kranzler et al., 2014b). Specifically, rs2832407*C-allele homozygotes treated with topiramate reported lower levels of drinking than those receiving placebo. This group also had the largest decreases in the expected positive effects of drinking (i.e., expectancies) and desire to drink. To extend that analysis, which focused on how mean levels of desire and expectancies changed over time with treatment, we used a within-person approach to examine whether daily variation in expectancies and desire to drink interact with topiramate treatment and genotype to predict nighttime drinking levels. In contrast to the previous analysis (Kranzler et al., 2014b), here we focus on whether alcohol expectancies and desire to drink moderate the effects of topiramate on drinking. Results showed a 3-way interaction of daily expectancies with genotype and medication, such that the protective effect of topiramate on nighttime drinking among rs2832407*C-allele homozygotes was decreased on days characterized by relatively high levels of anticipated positive effects of alcohol. There was no moderating effect of desire to drink or negative alcohol expectancies. Thus, there is specific moderation of the effects of topiramate by both genotype and cognitive process.

Abstract
Topiramate, which interacts with multiple neurotransmitter and enzyme systems, is approved by the Food and Drug Administration to treat seizure disorder, prevent migraine, and (in combination with phentermine) reduce weight. Topiramate has also been shown in multiple studies to reduce heavy drinking. The authors found that topiramate 200 mg/day significantly reduced heavy drinking in heavy drinkers with a treatment goal of reduced drinking (Kranzler et al., 2014). Further, in the European American (EA) subsample (n = 122), a single nucleotide polymorphism (rs2832407) in GRIK1, which encodes the GluK1 subunit of the kainate receptor, moderated the effect on heavy drinking days. Here the authors examined the effects of topiramate on body mass index (BMI) and the moderating effect of rs2832407 in the EA subsample from Kranzler et al. (2014). Across the 12 weeks of treatment, BMI was reduced by 1.2 kg/m2 (p < .001) in the topiramate group but was unchanged in the placebo group. There was no evidence of moderation by rs2832407 of topiramate's effects on BMI. Controlling for changes in drinking and other potential confounders did not alter the findings. These results suggest that the effect of topiramate on drinking behavior, in which the GluK1-containing kainate receptor appears to play a key role, can be dissociated from its effect on weight, the specific mechanism of which remains to be determined.

Abstract
We (Kranzler et al., 2014) reported that topiramate 200 mg/day reduced heavy drinking days and increased abstinent days in 138 heavy drinkers whose treatment goal was to reduce drinking to safe levels. In that 12-week, placebo-controlled study, we measured drinking using the Timeline Follow-back method at each treatment visit. In addition to the intent-to-treat effects of topiramate, we found that a single nucleotide polymorphism (rs2832407) in GRIK1, encoding the GluK1 subunit of the kainate receptor, moderated the treatment effect in European Americans (EAs; n = 122). Topiramate reduced heavy drinking only in rs2832407*C allele homozygotes. Here, we augment those analyses by using patients' daily reports obtained using interactive voice response technology; (a) to validate the interactive effects of GRIK1 and topiramate as predictors of drinking level; and, (b) to examine changes in expected positive effects of drinking (i.e. positive outcome expectancies) and desire to drink. We found that rs2832407*C allele homozygotes treated with topiramate drank less overall during treatment than those receiving placebo, validating our earlier findings for heavy drinking days (Kranzler et al., 2014). There was also a study day × medication group × genotype group interaction that predicted both positive alcohol expectancies and desire to drink, with rs2832407*C-allele homozygotes treated with topiramate showing the largest decreases in these outcomes during the study period. Changes in positive alcohol expectancies or desire to drink did not mediate the effects on drinking. These findings validate and extend our previous pharmacogenetic findings with topiramate.

Abstract
BACKGROUND Topiramate, a new generation antiepileptic agent with a complex mechanism of action, has a broad pharmacological profile which includes a neuroprotective effect. It has been proven to be efficacious in treating alcohol dependence through a previously confirmed association with memory processes. METHODS Topiramate was administered in single doses of 120 and 40 mg/kg and multiple doses of 60 mg/kg for 12 days. Its influence on the spatial memory of rats was evaluated using the Morris water maze test. The time needed to localize the platform, the distance travelled and time spent in the platform zone were recorded. RESULTS Single doses of topiramate induce deterioration of spatial memory, with high doses having more pronounced and longer lasting effects. Multiple administration of a medial dose does not significantly affect the learning process. CONCLUSIONS The influence of topiramate on the hippocampus-related memory processes may play a key role in its "anti-alcohol" effect.

Abstract
The antiepileptic levetiracetam (LEV) has been investigated for the treatment of alcohol abuse. However, little is known about how LEV alters the behavioral effects of alcohol in laboratory animals. The acute effects of LEV on alcohol drinking by male C57BL/6J mice were investigated using two different drinking procedures, limited access [drinking-in-the-dark (DID)] and intermittent access (IA) drinking. In the first experiment (DID), mice had access to a single bottle containing alcohol or sucrose for 4 h every other day. In the second experiment (IA), mice had IA to two bottles, one containing alcohol or sucrose and one containing water, for 24 h on Monday, Wednesday, and Friday. In both experiments, mice were administered LEV (0.3-100 mg/kg intraperitoneally) or vehicle 30 min before access to the drinking solutions. In the DID mice, LEV increased alcohol intake from 4.3 to 5.4 g/kg, whereas in the IA mice LEV decreased alcohol intake from 4.8 to 3.0 g/kg in the first 4 h of access and decreased 24 h alcohol intake from 20 to ∼15 g/kg. These effects appear specific to alcohol, as LEV did not affect sucrose intake in either experiment. LEV appears to differentially affect drinking in animal models of moderate and heavier alcohol consumption.

Abstract
BACKGROUND Health-related quality of life (HRQOL) is considered a valid measure of treatment effectiveness in addictions. However, alcohol research has lagged behind other biomedical fields in using HRQOL outcomes as primary or secondary endpoints. Previous work has suggested that psychiatric co-morbidity may mediate the relationship between alcohol dependence and HRQOL. AIM The goal was to summarize the literature on HRQOL and its domains in the context of alcohol dependence. A specific focus was on the impact of depression and other psychopathology on these areas of life. MATERIALS AND METHODS A database search of MEDLINE and PsychINFO was performed within the scope of PARADISE (Psychosocial fActors Relevant to brAin DISorders in Europe); a European Commission funded coordination action. Using pre-defined eligibility criteria, 42 studies were identified. A systematic approach to data collection was employed. RESULTS AND CONCLUSIONS Alcohol dependence was shown to affect overall HRQOL and its domains, including general health, physical and mental health, general and social functioning, activities of daily living, pain and sleep. The evidence demonstrating that alcohol dependence is a primary cause of impairments in overall HRQOL, general health, mental and physical health and social functioning was fairly strong. Treatment interventions helped improve HRQOL and its aforementioned domains. The reduction or cessation of alcohol use facilitated these improvements; however, it was not reported to be predictive of improvement in all instances where improvement was reported. Depression was associated with further decreases in HRQOL. Personality disorders contributed to the severity of social functioning impairment.

Abstract
PURPOSE To estimate variations in Overall Quality Of Life (OQOL) within 12 months following alcohol detoxification and to evaluate the predictive value of OQOL for relapse and alcohol use severity. METHODS Alcohol use disorders and four OQOL domains (physical health, psychological health, social relationships and environment) were assessed in 199 patients entering in-patient alcohol detoxification. Follow-up assessments were performed at 6 and 12 months after discharge. Cross-sectional and longitudinal analyses explored the relationship between OQOL and alcohol use severity, examining differences between abstinent and relapsed patients. The predictive value of OQOL was analyzed by logistic and linear regression. RESULTS Correlation between OQOL and Alcohol Use Disorders Identification Test scores was confirmed at all stages of observation. Abstinent patients showed a significant improvement in all OQOL domains at 6 months after discharge, whereas OQOL domains did not undergo any significant change in relapsed patients. Baseline OQOL did not prove to be predictive of either relapse or alcohol use severity. CONCLUSIONS Overall quality of life changed in parallel with alcohol use severity throughout the duration of the study, confirming it to be a useful and sensitive measure of secondary outcome for alcohol detoxification. Conversely, none of the OQOL baseline scores functioned as predictors of relapse within 12 months following discharge or alcohol use severity in relapsed patients.

Abstract
Disordered sleep is associated with a number of adverse health consequences and is an integral component of many psychiatric disorders. Rates of substance use disorders (SUDs) are markedly higher among individuals with post-traumatic stress disorder (PTSD), and this relationship may be partly mediated by disturbed sleep. Sleep disturbances (e.g. insomnia, daytime sleepiness, vivid nightmares) are hallmark features of PTSD and there is evidence that individuals with PTSD engage in substance use as a means of coping with these symptoms. However, prolonged substance use can lead to more severe sleep disturbances due to the development of tolerance and withdrawal. Behavioural or pharmacological treatment of disordered sleep is associated with improved daytime symptoms and psychosocial functioning among individuals who have developed PTSD. Initial research also suggests that improving sleep could be similarly beneficial in reducing coping oriented substance use and preventing relapse among those seeking treatment for SUDs. Together, these findings suggest that ameliorating sleep disturbance among at-risk individuals would be a viable target for the prevention and treatment of PTSD and associated SUDs, but prospective research is needed to examine this hypothesis. Enhanced understanding of the interrelation between sleep, PTSD, and SUDs may yield novel prevention and intervention approaches for these costly, prevalent and frequently co-occurring disorders.

Abstract
BACKGROUND Alcohol dependence is a major public health problem that is characterised by recidivism and a host of medical and psychosocial complications. Besides psychosocial interventions, different pharmacological interventions have been or currently are under investigation through Cochrane systematic reviews. OBJECTIVES The primary aim of the review is to assess the benefits/risks of anticonvulsants for the treatment of alcohol dependence. SEARCH METHODS We searched the Cochrane Drugs and Alcohol Group Trials Register (October 2013), PubMed (1966 to October 2013), EMBASE (1974 to October 2013) and CINAHL (1982 to October 2013). SELECTION CRITERIA Randomised controlled trials (RCTs) and controlled clinical trials (CCTs) comparing anticonvulsants alone or in association with other drugs and/or psychosocial interventions versus placebo, no treatment and other pharmacological or psychosocial interventions. DATA COLLECTION AND ANALYSIS We used standard methodological procedures as expected by The Cochrane Collaboration. MAIN RESULTS A total of 25 studies were included in the review (2641 participants). Most participants were male, with an average age of 44 years. Anticonvulsants were compared with placebo (17 studies), other medications (seven studies) and no medication (two studies). The mean duration of the trials was 17 weeks (range four to 52 weeks). The studies took place in the USA, Europe, South America, India and Thailand. Variation was reported in the characteristics of the studies, including their design and the rating instruments used. For many key outcomes, the risk of bias associated with unclear or unconcealed allocation and lack of blinding affected the quality of the evidence.Anticonvulsants versus placebo: For dropouts (16 studies, 1675 participants, risk ratio (RR) 0.94, 95% confidence interval (Cl) 0.74 to 1.19, moderate-quality evidence) and continuous abstinence (eight studies, 634 participants, RR 1.21, 95% Cl 95% 0.97 to 1.52, moderate-quality evidence), results showed no evidence of differences. Moderate-quality evidence suggested that anticonvulsants reduced drinks/drinking days (11 studies, 1126 participants, mean difference (MD) -1.49, 95% Cl -2.32 to -0.65) and heavy drinking (12 studies, 1129 participants, standardised mean difference (SMD) -0.35, 95% Cl -0.51 to -0.19). Moreover, withdrawal for medical reasons (12 studies, 1410 participants, RR 1.22, 95% Cl 0.58 to 2.56, moderate-quality evidence) showed no evidence of difference, but for specific adverse effects (nine studies, 1164 participants), two of 18 adverse event outcomes favoured placebo. The direction of results was confirmed by subgroup analyses for topiramate and partially for gabapentin and valproate.Anticonvulsants versus naltrexone: No evidence of difference was shown in dropout rates (five studies, 528 participants, RR 0.74, 95% CI 0.52 to 1.06), severe relapse rates (four studies, 427 participants, RR 0.69, 95% Cl 0.44 to 1.07) and continuous abstinence rates (five studies, 528 participants, RR 1.21, 95% Cl 0.99 to 1.49); anticonvulsants were associated with fewer heavy drinking days (three studies, 308 participants, MD -5.21, 95% Cl -8.58 to -1.83), more days to severe relapse (three studies, 244 participants, MD 11.88, 95% Cl 3.29 to 20.46) and lower withdrawal for medical reasons (three studies, 245 participants, RR 0.13, 95% Cl 0.03 to 0.58). AUTHORS' CONCLUSIONS At the current stage of research, randomised evidence supporting the clinical use of anticonvulsants to treat alcohol dependence is insufficient. Results are conditioned by heterogeneity and by the low number and quality of studies comparing anticonvulsants with other medications. The uncertainty associated with these results leaves to clinicians the need to balance possible benefits/risks of treatment with anticonvulsants versus other medications as supported by evidence of efficacy.

Abstract
Detoxification refers to the safe discontinuation from a substance of dependence and is distinct from relapse prevention. Detoxification usually takes between a few days and a few weeks to complete, depending on the substance being misused, the severity of dependence and the support available to the user. Psychosocial therapies alongside pharmacological treatments are essential to improve outcome. The dependencies considered in this overview are detoxification from opioids (with methadone, buprenorphine, α2-adrenoceptor agonists and adjunct medications), alcohol (with benzodiazepines, anti-glutamatergics and γ-aminobutyric acid (GABA)-ergic drugs), stimulants and cannabis (with no clear recommended pharmacological treatments), benzodiazepines (with dose tapering) and nicotine (with nicotine replacement therapy, antidepressants and partial agonists). Evidence is limited by a lack of controlled trials robust enough for review bodies, and more research is required into optimal treatment doses and regimes, alone and in combination.

Abstract
INTRODUCTION At present, the substances acamprosate, naltrexone and disulfiram are available for pharmacotherapy in alcohol dependence, but clinical studies found only modest effect sizes of these treatment options. AREAS COVERED This article focuses on current pharmacological treatment approaches for alcohol dependence, which have been evaluated in randomized, placebo-controlled trials (RCTs). EXPERT OPINION Besides the opioid system modulator nalmefene, which has recently been approved as a medication for the reduction of alcohol consumption, several compounds have been investigated in patients with alcohol dependence using a randomized, placebo-controlled design. In these studies, the antiepileptic drugs topiramate and gabapentin were found to be effective in improving several drinking-related outcomes, whereas levetiracetam failed to show efficacy in the treatment of alcohol dependence. Clinical studies using (low-dose) baclofen, a selective GABA-B receptor agonist, produced conflicting results, so that results of further trials are needed. Varenicline has also shown mixed results in two RCTs, but might possibly be useful in patients with comorbid nicotine dependence. The α1 adrenergic antagonist prazosin is currently under investigation in alcohol dependence with and without comorbid posttraumatic stress disorder (PTSD). Finally, first clinical evidence suggests that the 5-HT3 antagonist ondansetron might possibly be used in future within a pharmacogenetic treatment approach in alcohol dependence.

Abstract
Acute alcohol intoxication causes cellular changes in the brain that last for hours, while chronic alcohol use induces widespread neuroadaptations in the nervous system that can last a lifetime. Chronic alcohol use and the progression into dependence involve the remodeling of synapses caused by changes in gene expression produced by alcohol. The progression of alcohol use, abuse, and dependence can be divided into stages, which include intoxication, withdrawal, and craving. Each stage is associated with specific changes in gene expression, cellular function, brain circuits, and ultimately behavior. What are the molecular mechanisms underlying the transition from recreational use (acute) to dependence (chronic)? What cellular adaptations result in drug memory retention, leading to the persistence of addictive behaviors, even after prolonged drug abstinence? Research into the neurobiology of alcoholism aims to answer these questions. This chapter will describe the molecular adaptations caused by alcohol use and dependence, and will outline key neurochemical participants in alcoholism at the molecular level, which are also potential targets for therapy.

Abstract
Alcohol use disorder (AUD), a term that comprises both alcohol abuse and alcohol dependence, is a highly prevalent psychiatric disorder. Over 50% of treated AUD patients also suffer from other psychiatric disorder(s). Detailed study has revealed disorders across multiple psychiatric domains with rates of co-occurrence far greater than chance, suggesting a synergistic relationship. The basis of this synergy is explored along with its multiple forms, including behavioral and neurobiologic. Specific topics include the predisposition to both AUD and co-occurring psychopathology, the vulnerability to environmental risk factors that exacerbate these predispositions, and the nature of reinforcement in acute intoxication. Co-occurrence can also modify and exacerbate the neuroadaptations underpinning chronic dependence and relapse, the manifestations of acute and protracted withdrawal, emergence of medical and psychiatric complications, and ultimately the potential for relapse. The outcomes of co-occurrence as well as the unique impact it has on proper treatment are also discussed. Throughout, the significance of recognizing co-occurrence is emphasized since, both neurobiologically and clinically, the synergies between co-occurring disorders yield a result far more complex than a mere sum of the component disorders.

Emerging pharmacotherapies for alcohol dependence: a systematic review focusing on reduction in consumption. Drug Alcohol Depend 2013; 133:15-29. [PMID: 23746430 DOI: 10.1016/j.drugalcdep.2013.04.025] [Citation(s) in RCA: 35] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/07/2012] [Revised: 03/15/2013] [Accepted: 04/22/2013] [Indexed: 11/23/2022]
Abstract
BACKGROUND European Medicines Agency guidelines recognize two different treatment goals for alcohol dependence: abstinence and reduction in alcohol consumption. All currently approved agents are indicated for abstinence. This systematic review aimed to identify drugs in development for alcohol dependence treatment and to establish, based upon trial design, if any are seeking market authorization for reduction in consumption. METHODS We searched PubMed and Embase (December 2001-November 2011) to identify agents in development for alcohol dependence treatment. Additional studies were identified by searching ClinicalTrials.gov and the R&D Insight and Clinical Trials Insight databases. Studies in which the primary focus was treatment of comorbidity, or n≤20, were excluded. Studies were then classified as 'abstinence' if they: described a detoxification/alcohol withdrawal period; enrolled patients who had undergone detoxification previously; or presented relapse/abstinence rates as the primary outcome. Studies in patients actively drinking at baseline were classified as 'reduction in consumption'. RESULTS Of 602 abstracts identified, 45 full-text articles were eligible. Five monotherapies were in development for alcohol dependence treatment: topiramate, fluvoxamine, aripiprazole, flupenthixol and nalmefene. Nalmefene was the only agent whose sponsor was clearly seeking definitive approval for reduction in consumption. Development status was unclear for topiramate, fluvoxamine, aripiprazole and flupenthixol. Fifteen agents were examined in published exploratory investigator-initiated trials; the majority focused on abstinence. Ongoing (unpublished) trials tended to focus on reduction in consumption. CONCLUSIONS While published studies generally focused on abstinence, ongoing trials focused on reduction in consumption, suggesting a change in emphasis in the approach to treating alcohol dependence.

Abstract
Stimulant-related disorders (SRD) continue to be an important public health problem for which there are presently no approved pharmacotherapies. Although behavioral interventions provide some benefit response varies. The development of novel and effective pharmacotherapies continues to be a research priority. Understanding neural mechanisms critical to the action of stimulants has helped reveal several potential pharmacotherapies that have already shown promise in controlled clinical trials. Common to some of these medications is the ability to reverse neural deficits in individuals with SRD. Results from thoroughly conducted clinical trials continue to broaden our knowledge increasing the possibility of soon developing effective pharmacotherapies for SRD.

Abstract
BACKGROUND Alcohol use disorders (AUDs) are common among patients admitted to general hospitals. Unfortunately, AUDs often go undetected and untreated. Psychiatrists are frequently called upon to assist in the management of cases involving alcohol withdrawal. However, there is a dearth of knowledge regarding potential therapeutic approaches to AUDs beyond the acute withdrawal stage. OBJECTIVE This article presents an overview of the epidemiology, clinical characteristics, and treatment of AUDs on medical wards, with a specific focus on the post alcohol-withdrawal phase. METHOD This article is based on a survey of the published literature on AUDs and their treatment in the medical ward using the PubMed database. RESULTS Various screening tools are available to facilitate the detection of AUDs. Among non-medically ill patients, brief psychological interventions have proven to be effective in primary care and emergency room settings, while pharmacotherapy has been shown to reduce the risk of relapse. Existing data on the implementation of these interventions in the general hospital setting remain scarce. CONCLUSION Current evidence suggests the need for additional research in this area with a view toward clarifying AUD treatment guidelines for medically ill inpatients. The hospital stay could provide a valuable opportunity to initiate interventions for AUDs with medically ill patients, leading to significant changes in alcohol use behaviors and better health-related outcomes.
