Abstract
Alcohol use disorder (AUD) and chronic pain disorders are pervasive, multifaceted medical conditions that often co-occur. However, their comorbidity is often overlooked, despite its prevalence and clinical relevance. Individuals with AUD are more likely to experience chronic pain than the general population. Conversely, individuals with chronic pain commonly alleviate their pain with alcohol, which may escalate into AUD. This narrative review discusses the intricate relationship between AUD and chronic pain. Based on the literature available, the authors present a theoretical model explaining the reciprocal relationship between AUD and chronic pain across alcohol intoxication and withdrawal. They propose that the use of alcohol for analgesia rapidly gives way to acute tolerance, triggering the need for higher levels of alcohol consumption. Attempts at abstinence lead to alcohol withdrawal syndrome and hyperalgesia, increasing the risk of relapse. Chronic neurobiological changes lead to preoccupation with pain and cravings for alcohol, further entrenching both conditions. To stimulate research in this area, the authors review methodologies to improve the assessment of pain in AUD studies, including self-report and psychophysical methods. Further, they discuss pharmacotherapies and psychotherapies that may target both conditions, potentially improving both AUD and chronic pain outcomes simultaneously. Finally, the authors emphasize the need to manage both conditions concurrently, and encourage both the scientific community and clinicians to ensure that these intertwined conditions are not overlooked given their clinical significance.

Abstract
Baclofen is the only drug that has been investigated in randomized controlled studies for anti-craving in patients with alcohol use disorder (AUD) and liver disease. However, the results of its efficacy are controversial due to limited case numbers; therefore, a meta-analysis of all available studies is needed to verify efficacy and safety in this population. This systematic review and meta-analysis were conducted according to the Cochrane Collaboration Handbook (PROSPERO ID: CRD42021284439) clauses. PubMed, Embase, Medline, Cochrane, and Clinical Trials. Gov were searched for patients with AUD co-morbid liver diseases who used baclofen to maintain abstinence. The primary outcome was maintaining abstinence. Baclofen safety was evaluated by adverse reaction occurrence during treatment. A total of 322 patients with AUD co-morbid liver diseases (alcohol-related liver disease, hepatitis C, or cirrhosis) from five studies were included. The total abstinence rate was 53% (95% CI: 0.23-0.84). Specifically, the abstinence rate in patients with alcohol-related liver disease and cirrhosis was 63% and 55%, respectively. We further analyzed the two included randomized controlled studies to compare the efficacy between baclofen and a placebo. There was no significant difference in abstinence rates between baclofen and the placebo (RR: 1.42, 95% CI: 0.41-4.92). One serious adverse event was reported, and no cases of baclofen addiction were found. The abstinence rate in patients with AUD co-morbid liver diseases was 53%; however, the efficacy of baclofen for maintaining abstinence in this population still needs to be validated with further studies.

Abstract
INTRODUCTION Gambling disorder (GD) consists of a persistent, recurrent pattern of gambling that is associated with substantial distress or impairment. The etiology is multifactorial. GD frequently co-occurs with other psychiatric disorders and is often untreated. Different psychosocial interventions, particularly cognitive-behavioral therapy, are useful in the treatment of GD. Pharmacological therapy may also be helpful . No formal guidelines exist, and the management of the disease is often guided by few clinical elements. AREAS COVERED A literature search was performed using PubMed, Scopus, and Web of Science databases about treatment options for GD, considering both psychosocial treatments and available pharmacological ones. EXPERT OPINION The authors address whether and when it is appropriate to initiate pharmacological treatment for GD. They focus on providing clinicians with guidance on how to approach patients with GD in those situations where pharmacological therapy may be necessary. The reasons for the clinician to start thinking about a medication are examined. As specific traits in the psychopathology of GD may be managed with a strategic choice of the pharmacologic agent, the different available options are analyzed on the basis of their potential usefulness in GD. Issues that remain open about the pharmacological management of GD are summarized.

Abstract
Acute alcohol intoxication (AAI) is a harmful clinical condition, potentially life-threatening, secondary to the intake of large amounts of alcohol. Clinical manifestations of AAI are characterized by behavioural and neurological symptoms, even if its effects involve several organs and apparatus. Moreover, severe alcohol intoxication can produce a global neurological impairment leading to autonomic dysfunction, respiratory depression, coma and cardiac arrest. The evaluation of blood alcohol concentrations (BAC) is useful to confirm the suspicion of intoxication, both for clinical and legal reasons. Most of patients with AAI are referred to Emergency Departments due to behavioural, social, traumatic or clinical complications. Patient's stabilization is the first step in the management of AAI, in order to support vital functions and to prevent complications. Metadoxine represents a useful drug to increase ethanol metabolism and elimination. Given that AAI could represent a sentinel event of chronic alcohol abuse, patients presenting with acute intoxication should be screened for the presence of an underlying alcohol use disorder and referred to and an alcohol addiction unit to start a multidisciplinary treatment to achieve long term alcohol abstinence. The present review will focus on clinical features, diagnostic criteria and treatment strategies of AAI.

Abstract
Attention-Deficit/Hyperactivity Disorder (ADHD), Bipolar Disorder (BD) and Alcohol Use Disorder (AUD) are common medical conditions often coexisting and exerting mutual influence on disease course and pharmacological treatment response. Each disorder, when considered separately, relies on different therapeutic approaches, making it crucial to detect the plausible association between them. Treating solely the emerging condition (e.g., alcoholism) and disregarding the patient's whole psychopathological ground often leads to treatment failure and relapse. Clinical experience and scientific evidence rather show that tailoring treatments for these three conditions considering their co-occurrence as a sole complex disorder yields more fulfilling and durable clinical outcomes. In light of the above considerations, the purpose of the present review is to critically discuss the pharmacological strategies in the personalized treatment of complex conditions defined by ADHD-bipolarityalcoholism coexistence.

Abstract
Abstract
Background
Alcohol use disorder (AUD) and anxiety disorders (AnxD) are prevalent health concerns in clinical practice which frequently co-occur (AUD-AnxD) and compound one another. Concurrent AUD-AnxD poses a challenge for clinical management as approaches to treatment of one disorder may be ineffective or potentially counterproductive for the other disorder.
Case Presentation
We present the case of a middle-aged man with anxiety disorder, AUD, chronic pain, and gamma-hydroxybutyrate use in context of tapering prescribed benzodiazepines who experienced severe alcohol withdrawal episodes during a complicated course of repeated inpatient withdrawal management. After medical stabilization, the patient found significant improvement in symptoms and no return to alcohol use with a regimen of naltrexone targeting his AUD, gabapentin targeting both his AUD and AnxD, and engagement with integrated psychotherapy, Alcoholics Anonymous, and addictions medicine follow-up.
Conclusion
Proper recognition and interventions for AUD and AnxD, ideally with overlapping efficacy, can benefit individuals with comorbid AUD-AnxD. Gabapentin, tobacco cessation, and integrated psychotherapy have preliminary evidence of synergistic effects in AUD-AnxD. Meta-analysis evidence does not support serotoninergic medications (e.g. selective serotonin reuptake inhibitors) which are commonly prescribed in AnxD and mood disorders as their use has not been associated with improved outcomes for AUD-AnxD. Additionally, several double-blind placebo-controlled randomized trials have suggested that serotonergic medications may worsen alcohol-related outcomes in some individuals with AUD. Areas for future investigation are highlighted.

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
The knowledge about the effects of cannabis on human cortical brain processes is increasing. In this regard, transcranial magnetic stimulation (TMS) enables the evaluation of central nervous system function, including drug effects. Moreover, repetitive TMS (rTMS) has been used therapeutically in several substance use disorders. In this scoping review, we summarize and discuss studies that have employed TMS and rTMS techniques in users of cannabis for recreational purposes. In subjects with a history of persistent cannabis use, TMS studies showed reduced short-interval cortical inhibition (SICI). This observation points more at neurobiological changes of chronic cannabis use than to a direct effect of cannabis on gamma-aminobutyric acid (GABA) A receptors. Moreover, individuals vulnerable to becoming long-term users of cannabis may also have underlying pre-existing abnormalities in SICI. Of note, the use of cannabis is associated with an increased risk of schizophrenia, and the down-regulation of GABAergic function may play a role. Less frequent cannabis use and spontaneous craving were observed following rTMS applied to the dorsolateral prefrontal cortex (DLPFC). There is emerging evidence that the posterior cingulate cortex and the precuneus are potential targets for rTMS intervention in cannabis use disorder. However, larger and randomized trials should corroborate these encouraging findings.

Abstract
MetaBLIND is the largest meta-epidemiological study on the impact of blinding in randomized trials to date. We examined MetaBLIND data on the impact of blinding patients on patient-reported outcomes. 68 out of 132 included trials tested knowledge recall and had questionable relevance to clinical trials. In 17 out of 18 comparisons, the number of trials in the blinded or nonblinded group was 2 or lower. In several key trials, the blinding status was uncertain. Effect sizes compared in MetaBLIND appear to reflect random differences in study design and setting rather than the impact of blinding trial participants.

Therapeutic Potentials of Ketamine and Esketamine in Obsessive-Compulsive Disorder (OCD), Substance Use Disorders (SUD) and Eating Disorders (ED): A Review of the Current Literature. Brain Sci 2021; 11:brainsci11070856. [PMID: 34199023 PMCID: PMC8301752 DOI: 10.3390/brainsci11070856] [Citation(s) in RCA: 33] [Impact Index Per Article: 11.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2021] [Revised: 06/10/2021] [Accepted: 06/22/2021] [Indexed: 12/17/2022] Open
Abstract
The obsessive–compulsive spectrum refers to disorders drawn from several diagnostic categories that share core features related to obsessive–compulsive disorder (OCD), such as obsessive thoughts, compulsive behaviors and anxiety. Disorders that include these features can be grouped according to the focus of the symptoms, e.g., bodily preoccupation (i.e., eating disorders, ED) or impulse control (i.e., substance use disorders, SUD), and they exhibit intriguing similarities in phenomenology, etiology, pathophysiology, patient characteristics and clinical outcomes. The non-competitive N-methyl-D-aspartate receptor (NMDAr) antagonist ketamine has been indicated to produce remarkable results in patients with treatment-resistant depression, post-traumatic stress disorder and OCD in dozens of small studies accrued over the past decade, and it appears to be promising in the treatment of SUD and ED. However, despite many small studies, solid evidence for the benefits of its use in the treatment of OCD spectrum and addiction is still lacking. Thus, the aim of this perspective article is to examine the potential for ketamine and esketamine in treating OCD, ED and SUD, which all involve recurring and intrusive thoughts and generate associated compulsive behavior. A comprehensive and updated overview of the literature regarding the pharmacological mechanisms of action of both ketamine and esketamine, as well as their therapeutic advantages over current treatments, are provided in this paper. An electronic search was performed, including all papers published up to April 2021, using the following keywords (“ketamine” or “esketamine”) AND (“obsessive” OR “compulsive” OR “OCD” OR “SUD” OR “substance use disorder” OR “addiction” OR “craving” OR “eating” OR “anorexia”) NOT review NOT animal NOT “in vitro”, on the PubMed, Cochrane Library and Web of Science online databases. The review was conducted in accordance with preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines. The use and efficacy of ketamine in SUD, ED and OCD is supported by glutamatergic neurotransmission dysregulation, which plays an important role in these conditions. Ketamine’s use is increasing, and preliminary data are optimistic. Further studies are needed in order to better clarify the many unknowns related to the use of both ketamine and esketamine in SUD, ED and OCD, and to understand their long-term effectiveness.

Abstract
Background: There is a need for alcohol use disorder (AUD) pharmacotherapy that can be administered to actively drinking outpatients. Pregabalin, a gabapentoid anticonvulsant, has preliminary evidence supporting effects on alcohol withdrawal and AUD.Objectives: To evaluate the safety, tolerability, and optimal dosing of pregabalin for treating AUD.Methods: In an open-label, 8-week, outpatient trial of eighteen adults (nine women) with AUD, participants were titrated to 600 mg/day (or the maximum tolerated dose) over 3 weeks and then maintained for 5 weeks.Results: The majority (11/14, 78.6%) of participants with at least one-week of medication exposure achieved a maximum dose of 600 mg/day. Mean retention was 6.8 weeks (SD = 2.6). Eighty percent (12/15) of participants with post-enrollment data reported any adverse effects during the trial; and for those reporting adverse effects the most common were drowsiness (33.3%, 4/12), and fogginess (25%, 3/12), dizziness (25%, 3/12), and insomnia (25%, 3/12). Two participants discontinued study medication due to adverse effects and one had a dose reduction. Mean Heavy Drinking Days (HDD)/week decreased significantly by 3.43 days (SD = 2.47; median (IQR) = 4.00 (1.00 to 5.50)); Wilcoxon signed rank test statistic ((S) = 49.5, p = .0006). Mean proportion of HDD significantly decreased on average by 48.7% (SD = 35.1%; median (IQR) = 57.1% (14.3% to 78.6%)). The proportion of abstinent days increased significantly on average by 36.1% (SD = 35.0%; median (IQR) = 17.9% (14.3% to 75.0%); S = 49.5, p = .0005).Conclusions: Pregabalin treatment of AUD appears to be safe and well tolerated in doses up to 600 mg per day.Trial Registration: clinicaltrials.gov identifier: NCT03256253.

Abstract
INTRODUCTION Alcohol use disorder (AUD) is a complex psychiatric condition characterized by craving, compulsive seeking, loss of control of alcohol consumption as well as the emergence of negative emotional states during withdrawal. Despite the large socioeconomic burden of AUD, therapeutic treatment options lag behind. AREAS COVERED This review covers pharmacotherapies currently in phase I/II clinical trials for the treatment of AUDs listed on clinicaltrials.gov. We discuss drug therapies that modulate monoamine, GABA/Glutamate, neuropeptide and neuroimmune systems. We examine in depth preclinical and clinical evidence of a select range of these compounds and consider their utility in treating AUDs. EXPERT OPINION Current therapeutic options to treat AUD are inadequate at a population level. Currently there are 30 different compounds and one compound combination in phase I/II clinical trials for AUD. These compounds target various aspects of neurotransmitter signaling, neuroimmune modulation, and alcohol metabolism. Almost 75% of these compounds under trial are Food and Drug Administration (FDA) approved for other indications, which may save time and costs in treatment development. Further, development of therapeutics focused on genetic biomarkers and behavioral screening may improve how treatment decisions are made in the future on a case-by-case basis.

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
Patients who suffer from alcohol use disorders (AUDs) usually go through various socio-behavioral and pathophysiological changes that take place in the brain and other organs. Recently, consumption of unhealthy food and excess alcohol along with a sedentary lifestyle has become a norm in both developed and developing countries. Despite the beneficial effects of moderate alcohol consumption, chronic and/or excessive alcohol intake is reported to negatively affect the brain, liver and other organs, resulting in cell death, organ damage/failure and death. The most effective therapy for alcoholism and alcohol related comorbidities is alcohol abstinence, however, chronic alcoholic patients cannot stop drinking alcohol. Therefore, targeted therapies are urgently needed to treat such populations. Patients who suffer from alcoholism and/or alcohol abuse experience harmful effects and changes that occur in the brain and other organs. Upon stopping alcohol consumption, alcoholic patients experience acute withdrawal symptoms followed by a protracted abstinence syndrome resulting in the risk of relapse to heavy drinking. For the past few decades, several drugs have been available for the treatment of AUDs. These drugs include medications to reduce or stop severe alcohol withdrawal symptoms during alcohol detoxification as well as recovery medications to reduce alcohol craving and support abstinence. However, there is no drug that completely antagonizes the adverse effects of excessive amounts of alcohol. This review summarizes the drugs which are available and approved by the FDA and their mechanisms of action as well as the medications that are under various phases of preclinical and clinical trials. In addition, the repurposing of the FDA approved drugs, such as anticonvulsants, antipsychotics, antidepressants and other medications, to prevent alcoholism and treat AUDs and their potential target mechanisms are summarized.

Abstract
INTRODUCTION Alcohol misuse is the fifth leading risk factor for premature death and disability worldwide. Fewer than 10% of afflicted Americans receive pharmacological treatment for alcohol use disorder. Gabapentin is a calcium channel GABAergic modulator that is widely used for pain. Studies showing reduced drinking and decreased craving and alcohol-related disturbances in sleep and affect in the months following alcohol cessation suggest therapeutic potential for alcohol use disorder. Areas covered: Human laboratory and clinical studies assessing gabapentin for alcohol use disorder are reviewed. Data were obtained by searching for English peer-reviewed articles on PubMed, reference lists of identified articles, and trials registered on clinicaltrials.gov. Additionally, the mechanism of action of gabapentin specific to alcohol use disorder, and studies of gabapentin for alcohol withdrawal and non-alcohol substance use disorders are summarized. Expert opinion: Alcohol use disorder represents a challenge and large, unmet medical need. Evidence from single-site studies lend support to the safety and efficacy of gabapentin as a novel treatment for alcohol use disorder, with unique benefits for alcohol-related insomnia and negative affect, relative to available treatments. Proprietary gabapentin delivery systems may open a path to pivotal trials and registration of gabapentin as a novel treatment for alcohol use disorder.

Abstract
Patients with alcohol-use disorders (AUDs) have a high prevalence of anxiety disorders (AnxDs). "Co-occurring disorders" refers to the coexistence of an AUD and/or drug related disorders with another non-addictive psychiatric disorder. The aim of this study was to assess the effectiveness of psychopharmacological treatments and psychotherapy in patients with AUD and AnxD and to propose recommendations for the treatment of patients with comorbid AnxDs and AUDs. Randomized clinical trials, meta-analyses, and clinical guidelines were retrieved from PubMed, Embase, and Cochrane databases. Paroxetine was found to be effective in social anxiety patients with alcohol dependence. Selective serotonin reuptake inhibitors (SSRIs), especially sertraline, showed effective results in posttraumatic stress disorder and in comorbid AnxD-AUD. However, SSRIs should be used with caution when patients are actively drinking because they may increase alcohol consumption. Buspirone, gabapentin, and pregabalin were found to be effective in comorbid AnxD-AUD. The treatment of dual AnxDs should start as early as possible. Since AUDs and AnxDs can reinforce each other, treatments targeting both pathologies can be effective. Women suffer from higher levels of stress and AnxDs than men, and they are also more vulnerable to maintaining alcohol consumption levels. Further research is needed in this comorbid patient population, including the study of different types of patients and gender perspectives.

Abstract
Treatments for physical dependence and associated withdrawal symptoms following the abrupt discontinuation of prescription drugs (such as opioids and benzodiazepines), nicotine, alcohol, and cannabinoids are available, but there is still a need for new and more effective therapies. This review examines evidence supporting the potential use of pregabalin, an α2δ voltage-gated calcium channel subunit ligand, for the treatment of physical dependence and associated withdrawal symptoms. A literature search of the MEDLINE and Cochrane Library databases up to and including 11 December 2015 was conducted. The search term used was '(dependence OR withdrawal) AND pregabalin'. No other date limits were set and no language restrictions were applied. Works cited in identified articles were cross-referenced and personal archives of references also searched. Articles were included based on the expert opinions of the authors. There is limited evidence supporting the role of pregabalin for the treatment of physical dependence and accompanying withdrawal symptoms associated with opioids, benzodiazepines, nicotine, cannabinoids, and alcohol, although data from randomized controlled studies are sparse. However, the current evidence is promising and provides a platform for future studies, including appropriate randomized, placebo- and/or comparator-controlled studies, to further explore the efficacy and safety of pregabalin for the treatment of withdrawal symptoms. Given the potential for pregabalin misuse or abuse, particularly in individuals with a previous history of substance abuse, clinicians should exercise caution when using pregabalin in this patient population.

Abstract
OBJECTIVE The aim of this study was to identify if psychological distress may contribute to treatment outcome in alcohol-addicted patients during a follow-up period of 5 months after detoxification. METHODS As part of a prospective, multicenter, randomized study in relapse prevention, patients' levels of psychological distress were assessed using the Symptome Checklist (SCL-90-R). At study inclusion, all patients were detoxified and showed no more withdrawal symptoms. The patients who relapsed during the 5-month follow-up period were compared with those who remained abstinent. Predictors for relapse were investigated in a logistic regression. RESULTS First, a significant difference in initial psychological distress between patients who stayed abstinent and patients who relapsed was found: following detoxification, patients who relapsed scored significantly higher on the SCL-90-R at study inclusion. In addition, psychological distress differed over time in both groups. Second, patients without relapse showed a larger decrease in some SCL-90-R scales between the beginning and the end of the observation period than patients who relapsed. Third, the logistic regression analyses showed that high scores on the overall score GSI (Global Severity Index) of the SCL-90-R can be seen as a predictor for future relapse. CONCLUSION The SCL-90-R may be a useful instrument to predict relapse. As our study indicates that high levels of psychological distress increases the risk of relapse, specific interventions may be targeted at this risk factor.

Abstract
BACKGROUND The co-occurrence of bipolar disorder (BD) and gambling disorder (GD), though of clinical and public health importance, is still scarcely investigated. Comorbid BD-GD subjects experience a more severe course of illness and poorer treatment outcome, due to a range of clinical and psychosocial factors that collectively impede remission and recovery. The aim of our paper is to review the role of pharmacotherapy in the treatment of comorbid BD-GD, in order to support clinical decisions according to the best available evidence. METHODS A qualitative systematic review of studies on pharmacological treatment in comorbid BD-GD was performed. A comprehensive literature search of online databases, bibliographies of published articles and gray literature was conducted. Data on efficacy, safety and tolerability were extracted and levels of evidence were assessed. We also provide a brief overview of current epidemiological, neurobiological and clinical findings, with the intention of proposing a dimensional approach to the choice of available drugs. RESULTS The only drug with a high level of evidence is lithium. Considering the inclusion of GD in DSM-5 'Substance-related and Addictive Disorders' category, we discuss the use of other drugs with a high level of evidence currently used in BD subjects with co-occurring substance use disorders. LIMITATIONS Only few clinical trials are available and the population is limited; therefore no conclusive evidence can be inferred. CONCLUSIONS Further randomized controlled trials are required to evaluate the efficacy of pharmacological treatment strategies in large samples of patients with comorbid BD-GD. Also, attempts should be made to identify other shared clinical and psychopathological domains that are amenable to treatment.

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
INTRODUCTION Topiramate (TOP) and anticonvulsants in general are considered safe and effective drugs for the treatment of alcohol dependence, even though TOP-induced adverse events are quite common, especially for high initial doses or if titration to 300 mg/d is too rapid. The aim of the present study was to assess the efficacy and tolerability profile of low-dose TOP for relapse prevention. METHODS After detoxification, 52 patients were randomized into 2 groups as follows: 26 patients received 100 mg of TOP (oral, twice daily), titrated over 2 weeks, and 26 patients received placebo (PLA). Both groups underwent rehabilitation twice a week. RESULTS After 6 weeks of treatment, compared with the PLA group, patients receiving TOP showed the following: (1) fewer drinking days (P < 0.05); (2) less daily alcohol consumption (P < 0.05); (3) more days of treatment (P < 0.05); (4) reduced levels of craving (Obsessive-Compulsive Drinking Scale) and withdrawal symptoms (Clinical Institute Withdrawal Assessment for Alcohol-Revised); and (5) improvement of anxiety, depression, and obsessive-compulsive symptom severity (Symptom Check List 90 Revised). CONCLUSIONS Despite the small sample size and the short follow-up period, the present PLA-controlled study demonstrated the potential usefulness of TOP, even when administered at a dosage of 100 mg/d, for the treatment of detoxified alcohol-dependent subjects, confirming results from previous studies testing higher doses of TOP.

Abstract
INTRODUCTION Social anxiety disorder (SAD) is one of the most common psychiatric disorders, causing a reduction of in the quality of life by impairing functioning in social situations. The lifetime prevalence of SAD is estimated to be 12%. Selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs) are considered first-line drugs for SAD. However, new effective therapeutic options are still needed. Pregabalin is a novel anxiolytic, which seems to be a promising therapy for SAD. AREAS COVERED This review presents the results of three randomized controlled trials (RCTs) comparing the efficacy and safety of pregabalin with placebo in patients with generalized SAD. The authors also discuss the long-term safety and tolerability data from an extension study. EXPERT OPINION The results of the RCTs have demonstrated efficacy and safety with pregabalin at doses of 600 mg or 450 mg/d for treating generalized SAD. Thus, pregabalin may be an effective therapeutic option, especially for patients who cannot tolerate the adverse effects or who demonstrate a lack of efficacy with SSRIs or SNRIs. In addition to being an alternative therapy to SSRIs or SNRIs, it may also have value as an add-on therapy, either to augment pharmacotherapy or in addition to cognitive-behavioral therapy.

Abstract
Introduction: Alcohol dependence is one of the most important psychiatric disorders leading to enormous harm in individuals and indeed within society. Yet, although alcohol dependence is a disease of significant importance, the availability of efficacious pharmacological treatment is still limited. Areas covered: The current review focuses on neurobiological pathways that are the rationale for recent preclinical and clinical studies testing novel compounds that could be used as treatments for alcohol dependence. These neurobiological mechanisms include the: glutamatergic, dopaminergic and GABA mediated pathways as well as neuroendocrine systems. There is also an interest in the approaches for influencing chromatin structure. Expert opinion: There are several compounds in Phase I and Phase II clinical studies that have produced potentially useful results for the treating alcoholism. Further evaluation is still necessary, and the implementation of Phase III studies will help to elucidate the usefulness of these compounds. It is important that personalized approaches (e.g., pharmacogenomics) are investigated in these later studies, as the efficacy of different compounds may vary substantially between subgroups of patients.

Abstract
Objective. Comorbidities between psychiatric diseases and consumption of traditional substances of abuse (alcohol, cannabis, opioids, and cocaine) are common. Nevertheless, there is no data regarding the use of novel psychoactive substances (NPS) in the psychiatric population. The purpose of this multicentre survey is to investigate the consumption of a wide variety of psychoactive substances in a young psychiatric sample and in a paired sample of healthy subjects. Methods. A questionnaire has been administered, in different Italian cities, to 206 psychiatric patients aged 18 to 26 years and to a sample of 2615 healthy subjects matched for sex, gender, and living status. Results. Alcohol consumption was more frequent in the healthy young population compared to age-matched subjects suffering from mental illness (79.5% versus 70.7%; P < 0.003). Conversely, cocaine and NPS use was significantly more common in the psychiatric population (cocaine 8.7% versus 4.6%; P = 0.002) (NPS 9.8% versus 3%; P < 0.001). Conclusions. The use of novel psychoactive substances in a young psychiatric population appears to be a frequent phenomenon, probably still underestimated. Therefore, careful and constant monitoring and accurate evaluations of possible clinical effects related to their use are necessary.

Abstract
AIMS Gender-related differences in the pharmacological effects of addictive drug are an emerging issue. This review examines gender differences in both pharmacokinetic and pharmacodynamic aspects of alcohol and cocaine intake since they cause complex pharmacological interactions, not least the formation of the active metabolite cocaethylene. METHODS The MEDLINE database was searched from 1990 to 2014 in order to find articles related to gender differences in alcohol, cocaine and cocaethylene pharmacokinetics and pharmacodynamics. RESULTS Besides the well known gender differences in alcohol pharmacokinetics, women appear more susceptible to alcohol-mediated brain damage and seem to suffer more than men the acute effects of alcohol on hepatic and gonadal hormones. No significant gender differences have been found in the pharmacokinetics of cocaine taken alone; yet, in women pharmacological sensitivity to the drug seems to vary in relation to menstrual cycle; moreover, progesterone attenuates subjective effects of cocaine in women. Higher ratings at a subjective measure of mental/physical well-being have been observed in women when given cocaine and alcohol, alone or in combination. Finally, among subjects dependent on both alcohol and cocaine, men only benefit from naltrexone, whereas women used more cocaine during the trial and were less compliant to therapy than men. CONCLUSIONS The observed subtle gender differences in the pharmacokinetics and pharmacodynamics of both alcohol and cocaine may have no subtle influence on the natural history of the co-abuse of the two drugs by women.

Abstract
Gabapentinoids (e.g. pregabalin and gabapentin) are widely used in neurology, psychiatry and primary healthcare but are increasingly being reported as possessing a potential for misuse. In fact, increasing levels of both prescriptions and related fatalities, together with an anecdotally growing black market, have been reported from a range of countries. This article reviews the current evidence base of this potential, in an attempt to answer the question of whether there is cause for concern about these drugs. Potent binding of pregabalin/gabapentin at the calcium channel results in a reduction in the release of excitatory molecules. Furthermore, gabapentinoids are thought to possess GABA-mimetic properties whilst possibly presenting with direct/indirect effects on the dopaminergic 'reward' system. Overall, pregabalin is characterized by higher potency, quicker absorption rates and greater bioavailability levels than gabapentin. Although at therapeutic dosages gabapentinoids may present with low addictive liability levels, misusers' perceptions for these molecules to constitute a valid substitute for most common illicit drugs may be a reason of concern. Gabapentinoid experimenters are profiled here as individuals with a history of recreational polydrug misuse, who self-administer with dosages clearly in excess (e.g. up to 3-20 times) of those that are clinically advisable. Physicians considering prescribing gabapentinoids for neurological/psychiatric disorders should carefully evaluate a possible previous history of drug abuse, whilst being able to promptly identify signs of pregabalin/gabapentin misuse and provide possible assistance in tapering off the medication.

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 Craving is commonly thought to play a crucial role both in the transition from controlled drinking to alcohol dependence and in the mechanism underlying relapse. However there is no consensus on its definition, and on its correct assessment. Another significant hindrance is that craving is almost certainly a multi-faceted construct. To this respect a three pathway psychobiological model able to differentiate craving into a reward, relief, and obsessive component has been suggested. METHODS CTQ was administered to 547 control subjects and to 100 alcohol dependent patients. The dimensional structure of the questionnaire, through the principal component analysis, the reliability and the threshold values were evaluated in both the control and clinical sample. RESULTS The results showed and confirmed that the CTQ is composed of three dimensions. Cronbach's alpha coefficients suggest that the questionnaire is reliable. Alcohol-dependent subjects had a significantly higher mean score as compared to the normative sample in both Reward, Relief, Obsessive craving. Younger age correlated with higher scores on Reward craving (r=0.38; p<0.001) and males reported significantly higher scores than women on Reward craving (t=4.36; p<0.001). DISCUSSION CTQ showed to be a reliable and valid questionnaire to distinguish a normative sample from pathological individuals. The average scores obtained represent the first normative data available for this questionnaire. Identifying a craving type may represent an important predicting or matching variable for anti-craving psychotropics. More research is needed with respect to CTQ's external validity, i.e. correlations with phenotypic, endophenotypic and genetic indicators of relief, reward and obsessive drinking.

Abstract
Pregabalin (Lyrica™) is a structural analog of γ-aminobutyric acid (GABA) and is approved by the FDA for partial epilepsy, neuropathic pain and generalized anxiety disorders. Pregabalin also reduces excitatory neurotransmitter release and post-synaptic excitability. Recently, we demonstrated that pregabalin reduced alcohol intake and prevented relapse to the alcohol seeking elicited by stress or environmental stimuli associated with alcohol availability. Here, we sought to extend these findings by examining the effect of pregabalin on cocaine self-administration (0.25 mg/infusion) and on cocaine seeking elicited by both conditioned stimuli and stress, as generated by administration of yohimbine (1.25 mg/kg). The results showed that oral administration of pregabalin (0, 10 or 30 mg/kg) reduced self-administration of cocaine over an extended period (6 hours), whereas it did not modify self-administration of food. In cocaine reinstatement studies, pregabalin (10 and 30 mg/kg) abolished the cocaine seeking elicited by both the pharmacological stressor yohimbine and the cues predictive of cocaine availability. Overall, these results demonstrate that pregabalin may have potential in the treatment of some aspects of cocaine addiction.

Abstract
This study examined the actions of pregabalin and topiramate on behavioural and gene transcription alterations induced by spontaneous cannabinoid withdrawal in mice. Tolerance was induced in mice by administration of CP-55,940 (0.5 mg/kg/12 hours; i.p.; 7 days). Behavioural assessment of spontaneous cannabinoid withdrawal was performed by measuring motor activity, somatic signs and anxiety-like behaviour on days 1 and 3 after cessation of treatment with CP-55,940. On days 1-3 of cannabinoid withdrawal, mice received pregabalin (40 mg/kg/12 hours; p.o.) or topiramate (50 mg/kg/12 hours; p.o.) and their actions on signs of withdrawal and anxiety-like behaviour were evaluated. The administration of CP-55,940 decreased rectal temperature and motor activity on day 1. On day 1 after interruption of cannabinoid administration, motor activity and the number of rearings increased compared with control group. Anxiety-like behaviour induced by cessation of cannabinoid treatment increased significantly on days 1 and 3 of withdrawal. The administration of pregabalin or topiramate blocked the motor signs and reduced significantly anxiety-like behaviour. Cannabinoid withdrawal decreased tyrosine hydroxylase (TH) gene expression in the ventral tegmental area and µ-opioid receptor gene expression in the nucleus accumbens (NAcc) and increased CB1 receptor gene expression in the NAcc. Treatment with topiramate or pregabalin blocked the decrease of TH and the increase of CB1 gene expressions induced by cannabinoid withdrawal. Both drugs failed to alter µ-opioid receptor gene expression. These results suggest that pregabalin and topiramate may result useful for the treatment of anxiety-like behaviour and motor symptoms associated with spontaneous cannabinoid withdrawal.

Abstract
BACKGROUND AND PURPOSE Impulsivity is a core symptom in many neuropsychiatric disorders. The main objective of this study was to evaluate the effects of topiramate and pregabalin on the modulation of different impulsivity dimensions in DBA/2 mice. EXPERIMENTAL APPROACH The effects of acute and chronic administration of pregabalin (10, 20 and 40 mg·kg(-1) ) and topiramate (12.5, 25 and 50 mg·kg(-1) ) were evaluated in the light-dark box (LDB), hole board test (HBT) and delayed reinforcement task (DRT). α(2A) -Adrenoceptor, D(2) -receptor and TH gene expression were evaluated by real-time PCR in the prefrontal cortex (PFC), accumbens (ACC) and ventral tegmental area (VTA), respectively. KEY RESULTS Acute pregabalin administration showed a clear anxiolytic-like effect (LDB) but did not modify novelty-seeking behaviour (HBT). In contrast, topiramate produced an anxiolytic effect only at the highest dose, whereas it reduced novelty seeking at all doses tested. In the DRT, acute pregabalin had no effect, whereas topiramate only reduced motor impulsivity. Chronically, pregabalin significantly increased motor impulsivity and topiramate diminished cognitive impulsivity. Pregabalin decreased α(2A) -adrenoceptor and D(2) -receptor gene expression in the PFC and ACC, respectively, and increased TH in the VTA. In contrast, chronic administration of topiramate increased α(2A) -adrenoceptor and D(2) -receptor gene expression in the PFC and ACC, respectively, and also increased TH in the VTA. CONCLUSIONS AND IMPLICATIONS These results suggest that the usefulness of pregabalin in impulsivity-related disorders is related to its anxiolytic properties, whereas topiramate modulates impulsivity. These differences could be linked to their opposite effects on α(2A) -adrenoceptor and D(2) -receptor gene expression in the PFC and ACC, respectively.

Abstract
INTRODUCTION Alcohol dependence represents a severe pathological disorder associated with a significant rate of morbidity and mortality. To date, limited pharmacological agents exist to treat this disorder, and there is a growing interest for new therapies. In this context, pregabalin represents a promising strategy. Pregabalin, like gabapentin, selectively binds to the α(2)δsubunit of voltage-gated calcium channels, inhibiting release of excessive levels of excitatory neurotransmitters. The main focus of this review is the clinical use of pregabalin in alcoholic patients, but the authors also reported some data about chemistry, pharmacology, and pharmacokinetics of this drug. METHODS The authors conducted a PubMed search of clinical human studies published in English from January 2000 to August 2012 using the following search terms: pregabalin alcohol dependence, pregabalin alcohol withdrawal, pregabalin alcoholism. RESULTS The search revealed a total of five studies: two trials for the treatment of alcohol relapse and three articles for the management of alcohol withdrawal syndrome with pregabalin. The critical review of the literature suggests that pregabalin could be a novel and effective treatment option for the management of alcohol relapse in detoxified patients, whereas until now there have been mixed results for the treatment of alcohol withdrawal syndrome. In particular, pregabalin showed a greater beneficial effect on patients with comorbid conditions such as alcoholism and generalized anxiety disorders. The exact mechanism of action of pregabalin in the management of alcoholism is not well understood but it is thought to be due mainly to the modulation of neurotransmitters such as glutamate and norepinephrine by inhibiting activity-dependent calcium influx in nerve terminals. CONCLUSION Pregabalin, within a dosage of 150-450 mg/day, showed beneficial effects for alcohol relapse prevention and contrasting results for the treatment of the withdrawal syndrome. Its use appears to be safe and well tolerated.

Abstract
The British Association for Psychopharmacology guidelines for the treatment of substance abuse, harmful use, addiction and comorbidity with psychiatric disorders primarily focus on their pharmacological management. They are based explicitly on the available evidence and presented as recommendations to aid clinical decision making for practitioners alongside a detailed review of the evidence. A consensus meeting, involving experts in the treatment of these disorders, reviewed key areas and considered the strength of the evidence and clinical implications. The guidelines were drawn up after feedback from participants. The guidelines primarily cover the pharmacological management of withdrawal, short- and long-term substitution, maintenance of abstinence and prevention of complications, where appropriate, for substance abuse or harmful use or addiction as well management in pregnancy, comorbidity with psychiatric disorders and in younger and older people.

Abstract
Pregabalin acts as a presynaptic modulator of excitatory neurotransmitter release, binding to the α²-δ subunit protein of voltage-gated calcium channels. Pregabalin use is becoming widespread in the psychiatric scenario. Data are encouraging, with some good evidence for efficacy in anxious spectrum, benzodiazepine abuse/dependence, and alcoholism. The abuse potential, however, is an issue that should be taken into account, mostly in subjects at risk for developing substance/alcohol misuse.

Abstract
INTRODUCTION Both alcohol and benzodiazepine dependence (AD, BD) are severe and chronic conditions with devastating physical and mental health effects. The relative scarcity and controversial evidential status of available pharmacological interventions for the treatment of patients' acute withdrawal syndrome and/or relapse prevention call for the clinical investigation of novel safe and efficacious agents. AREAS COVERED We review published studies of pregabalin as monotherapy in the treatment of AD and BD in more than 450 patients. Available evidence includes four RCTs, two in AD with active comparator drugs (naltrexone, tiapride, and lorazepam) and one placebo-controlled, and one placebo-controlled in BD. We also review other available studies on pregabalin's potential to reduce benzodiazepine consumption, its side effects, especially cognitive, as well as extant reports on its liability for abuse. EXPERT OPINION Available evidence suggests that monotherapy with pregabalin, within the dosage range of 150 - 600 mg/d, is a promising "novel" option for the safe and efficacious relapse prevention of both AD and BD. However, its efficacy as monotherapy in the acute treatment of AD withdrawal syndrome is still controversial. Clinicians should be cautious in prescribing pregabalin to patients with a history of multiple substance recreational use, and monitor its effects on cognition at dosages above 450 mg/d. Further, well-designed clinical research is still needed for the eventual consolidation of pregabalin's place in the treatment of AD and BD.

Abstract
RATIONALE Pregabalin (Lyrica™) is a structural analogue of γ-aminobutyric acid (GABA) approved by FDA for partial epilepsy, neuropathic pain and recently generalized anxiety disorder. While the exact cellular mechanism of action of pregabalin is still unclear, evidence from several studies suggests that it reduces excitatory neurotransmitter release and postsynaptic excitability. OBJECTIVES Based on these mechanisms we sought interesting to evaluate the effect of pregabalin on alcohol-abuse-related behaviours. MATERIALS AND METHODS For this purpose, using genetically selected alcohol-preferring Marchigian Sardinian (msP) rats, we evaluated the effect of pregabalin on alcohol drinking and relapse to alcohol seeking elicited by environmental conditioning factors or stress. RESULTS Our results showed that treatment with pregabalin (0, 10, 30 and 60 mg/kg) given orally selectively reduced home cage alcohol drinking in msP rat. This effect was confirmed in self-administration experiments where pregabalin (0, 10 and 30 mg/kg) significantly reduced operant responding for alcohol but not for food. Using alcohol reinstatement models we also found that pregabalin (0, 10 and 30 mg/kg) abolished seeking behaviour elicited by the pharmacological stressor yohimbine as well as cues predictive of alcohol availability. CONCLUSIONS Results demonstrate that pregabalin may have potential in the treatment of alcohol addiction.

Abstract
AIMS The objective of this study was to collect preliminary data on the efficacy and safety of pregabalin in attenuating the severity of alcohol withdrawal symptoms during detoxification treatment in alcohol dependence. METHODS Forty-two alcohol-dependent patients with an alcohol withdrawal syndrome (AWS) were included in the prospective randomized double-blind placebo-controlled trial during inpatient alcohol detoxification. For 6 days, participants either received pregabalin or placebo according to a fixed dose schedule starting with 300 mg/day. Depending on the score of the AWS Scale (AWSS), diazepam was additionally administered as a rescue medication. The primary endpoint was the total amount of diazepam required from Day 2 to 6 of detoxification treatment in each of the two groups. Secondary outcome variables were the difference in AWSS and Clinical Institute Withdrawal Assessment for Alcohol (CIWA-Ar) scores between Day 2 and 6, tolerability and safety data, drop-out rates as well as changes in the neuropsychological scales. RESULTS Pregabalin and placebo were equally safe and well tolerated. However, no statistically significant difference was found comparing the total amount of additional diazepam medication required in the two study groups. Pregabalin and placebo also showed similar efficacy according to alterations of scores of the AWSS, CIWA-Ar and neuropsychological scales. The frequency of adverse events and drop-outs did not differ between the both treatment groups. CONCLUSIONS The study demonstrates the relative safety of pregabalin in the treatment of AWS. However, the results do not provide evidence in favor of pregabalin compared with placebo concerning its efficacy in the treatment of AWS.

Abstract
The clinical interface between psychiatry and neurology is epilepsy; the pharmacological expression of this interface is antiepileptic drugs (AEDs), as they are used to treat both epilepsy and psychiatric disorders, especially bipolar disorders. The prevalence of psychiatric comorbidity and the risk of suicidal behavior/ideation/suicide are markedly increased in patients with epilepsy (PWE). Though AEDs receive initial indications for the treatment of epilepsy, currently the majority of AEDs are used to treat pain and psychiatric disorders. Thus in selecting the appropriate AEDs for treatment of PWE, consideration should be given to which AEDs best treat the epileptic disorder and the psychiatric comorbidity. This review is an overview of 21 AEDs in which negative psychotropic properties, approved indications in psychiatry, off-label studied uses in psychiatry, and principal uses in psychiatry are presented with literature review. A total of 40 psychiatric uses have been identified. Of the 21 AEDs reviewed, only 5 have U.S. Food and Drug Administration and/or European Medicines Agency psychiatric approval for limited uses; the majority of AEDs are used off-label. Many of these off-label uses are based on case reports, open-label studies, and poorly controlled or small-sample-size studies. In some instances, off-label use persists in the face of negative pivotal trials. Further placebo-controlled (augmentation and monotherapy) parallel-arm research with active comparators is required in the complex field of AED treatment of psychiatric disorders to minimize the treatment gap not only for PWE with psychiatric disorders, but also for psychiatric patients who would benefit from properly studied AEDs while minimizing adverse effects.

Abstract
AIM To evaluate the effectiveness of pregabalin as a tapering therapy on the subjective sleep quality of patients who underwent a benzodiazepine withdrawal program in routine medical practice. METHODS Secondary analysis of a 12-week prospective, open noncontrolled study carried out in patients who met DSM-IV-TR criteria for benzodiazepine dependence. Sleep was evaluated with the Medical Outcomes Study Sleep Scale (MOS Sleep Scale). RESULTS 282 patients were included in the analysis. Mean (±SD) pregabalin dose was 315 ± 166 mg/day at the end of the trial. We observed a significant and clinically relevant improvement in sleep outcomes at the endpoint, with a total score reduction from 55.8 ± 18.9 to 25.1 ± 18.0 at week 12 (i.e. a 55% reduction). Similar findings were apparent using the six dimensions of the MOS Sleep Scale. Moderate correlations were observed between the MOS Sleep summary index and sleep domains, and there were improvements in anxiety symptoms and disease severity. CONCLUSIONS These findings suggest that pregabalin may improve subjective sleep quality in patients who underwent a benzodiazepine withdrawal program. This effect appears to be partly independent of improvements in symptoms of anxiety or withdrawal. However, controlled studies are needed to establish the magnitude of the effect of pregabalin.

Abstract
Substance use is ubiquitous among medically ill patients. The 2008 National Survey on Drug Abuse and Health survey estimated that 20.1 million Americans aged 12 years or older (8% of the US population) had used an illicit drug during the preceding month. Some licit substances also create havoc. The survey found that slightly more than half (56%) of Americans reported being current drinkers of alcohol. A total of 6.2 million (2.5%) Americans used prescription-type psychotherapeutic drugs for nonmedical purposes and 70.9 million Americans (or 28.4%) used tobacco during the survey period. Substance abuse problems were diagnosed in up to 36% of medically hospitalized patients for whom a psychiatric consultation was requested. Given how prevalent the use of substances is among the medically ill and their potential effect on comorbid medical conditions, it is important for physicians to be mindful of their prevalence and presentation. This article covers the presenting symptoms of intoxication and withdrawal states, addresses the acute management of the most commonly encountered substances, and summarizes all others in a table.

Abstract
We review all available studies on the use of the newer anticonvulsant drug pregabalin (PGB) in the treatment of both alcohol dependence (AD) and benzodiazepine dependence (BD). In AD, the available evidence includes one open-label and one double-blind randomized studies, whereas in BD, only a few case reports and one open-label study are as yet available. In both conditions, PGB was found efficacious with significant improvement in withdrawal symptoms at the dosage ranges of 150-450 mg/day (AD) and 225-900 mg/day (BD). Moreover, its side effects were mild and transient. Despite the limited quality of the studies design, their findings suggest that PGB might constitute a novel efficacious and safe option in the treatment of both AD and BD.
