Abstract
BACKGROUND Tiapride is an atypical antipsychotic used to treat alcohol withdrawal, aggressiveness and agitation, headache, dyskinesias, tic and Tourette's disorder. More recently, it has been proposed for the treatment of delirium and agitation in hospitalised patients with COVID-19. Although its safety profile makes it suitable for use in vulnerable populations, the use of tiapride for psychiatric disorders is limited. This work aims to systematically review the available evidence on the efficacy and tolerability of tiapride in individuals with a psychiatric disorder. METHODS We searched PubMed, Embase, PsycINFO, GreyLit, OpenGrey, and ProQuest up to March 2020 for randomised controlled trials focussing on the use of tiapride in the treatment of individuals with a psychiatric disorder (e.g., mood disorder, schizophrenia spectrum, substance use disorder). The Risk of Bias 2 was performed for the quality assessment of the included studies. RESULTS We identified 579 records. Of them, six studies (published between 1982 and 2010) were included in the review. Four studies referred to alcohol withdrawal, and two to the management of agitation in elderly patients with dementia. None of the studies reported significant differences between tiapride and other active comparators in terms of efficacy and tolerability. The overall risk of bias was moderate to high. CONCLUSION Tiapride may be considered as a relatively safe treatment option for selected patients with alcohol withdrawal or agitation in dementia. However, solid evidence of its efficacy in the scientific literature is lacking. High-quality trials remain necessary to fully sustain its use in clinical practice.

Abstract
AIM To examine the efficacy and safety of antiepileptic drugs (AED) for the inpatient treatment of patients with moderate to severe alcohol withdrawal syndrome (AWS). METHODS We searched in databases and gray literature to include randomized controlled clinical trials in adults that compare the use of AED versus placebo or any other medication. Studies that did not specify severity or were performed on an outpatient basis were excluded. The outcomes were improvement of symptoms, delirium tremens, seizures and adverse events. Two researchers independently selected the references, extracted the data and assessed the risk of bias. A qualitative synthesis was made and, when the heterogeneity was mild or moderate, a meta-analysis was performed. The quality of the evidence obtained was evaluated with the Grading of Recommendations Assessment, Development and Evaluation tool. RESULTS In total, 26 studies with 1709 patients were included. No benefit is described in withdrawal syndrome severity measured by scales or in the development of delirium tremens. The only possible meta-analysis showed that there are no differences in the incidence of seizures (risk ratio [RR] = 1.0; confidence interval (CI) 95% 0.76-1.33), even when compared with placebo (RR = 0.95; CI95% 0.57-1.57). There were also no differences in adverse events, although a higher proportion of some mild cases were described with the use of carbamazepine and valproic acid. CONCLUSIONS The routine use of AED is not suggested in the treatment of patients with moderate or severe AWS unless indicated for comorbidity (weak recommendation against using moderate quality of evidence).

Abstract
Objective: To review the clinical evidence to determine the efficacy and safety of valproic acid in the management of alcohol withdrawal syndrome (AWS). Data Sources: MEDLINE (1966–February 2006), EMBASE (1980–February 2006), and PubMed (1966–February 2006) searches identified pertinent studies that were conducted in humans and published in English. Key words used for identification of articles included valproic acid, ethanol, alcohol, alcoholism, alcohol withdrawal delirium, alcohol withdrawal seizures, and substance withdrawal syndrome. References of identified articles were manually searched. Study Selection and Data Extraction: All controlled clinical trials that evaluated the use of valproic acid for the management of AWS in humans were included. Data Synthesis: Comparisons were made among various regimens of valproic acid and traditional therapy with benzodiazepine or nonbenzodiazepine agents. Only 2 of 6 trials reported a statistically significant difference in favor of valproic acid on endpoints of AWS. However, these differences were of marginal clinical significance. The number of patients included in these studies did not allow for adequate evaluation of safety. Conclusions: The existing limited efficacy and safety data suggest that valproic acid should not replace conventional therapy or be used as adjunct therapy for management of mild-to-moderate AWS.

Abstract
INTRODUCTION The aim of this trial was to compare lorazepam with non-benzodiazepine medications such as pregabalin and tiapride in the treatment of alcohol withdrawal syndrome (AWS). These drugs were chosen for their inhibitorial effects on the hypersecretion of neurotransmitters usually observed in AWS. Craving reduction and improvement of psychiatric symptoms were the secondary end-points. METHODS One hundred and ninety subjects affected by current alcohol dependence were considered consecutively: 111 were enrolled and divided into three groups of 37 subjects each. Within a treatment duration of 14 days, medication was given up to the following maximum doses (pregabalin 450 mg/day; tiapride 800 mg/day; lorazepam 10 mg/day). Withdrawal (CIWA-Ar), craving [visual analogue scale (VAS); Obsessive and Compulsive Drinking Scale (OCDS)], psychiatric symptoms [Symptom Check List 90 Revised (SCL-90-R)] and quality of life (QL-index) rating scales were applied. RESULTS On the CIWA-Ar score, all the groups showed a significant reduction between times (P < 0.001) with a higher reduction for the pregabalin group (P < 0.01) on items regarding headache and orientation. Retention in treatment was lower in the tiapride group (P < 0.05), while the number of subjects remaining alcohol free was higher in the pregabalin group (P < 0.05). Significant reduction between baseline and the end of the treatment was found in all the groups at the OCDS and the VAS for craving, at the SCL-90-R and QL-index (P < 0.001). DISCUSSION All the medications in the trial showed evidence of safety and efficacy in the treatment of uncomplicated forms of AWS, with some particular differences. The efficacy of pregabalin was superior to that of tiapride, used largely in research trials and, for some measures, to that of the 'gold standard', lorazepam. Accordingly, pregabalin may be considered as a potentially useful new drug for treatment of AWS, deserving further investigation.

Abstract
Individuals suffering from drug addiction may also manifest features of bipolar spectrum disorders. Hyperthymic and cyclothymic temperaments may render individuals vulnerable to later development of substance abuse. Bipolar disorders themselves may be altered or precipitated by substance use, most notably by stimulants (amphetamines), alcohol, and cannabinoids. The clinical usefulness of mood stabilizers, particularly antiepileptics, has been established as safe and effective in substance abusers with and without comorbid mood disorders. Most studies on this issue have been of short duration and focused on the resolution of a currently manifest period of illness. Few studies have been conducted on the usefulness of these drugs on the long-term longitudinal course of these diseases, such as frequently encountered recurrent relapses into states of agitation, impulsivity, and/or dissatisfaction. As opposed to the clinical experience with traditional antidepressants and neuroleptics, antiepileptics do not induce counter-polar states (depressed patients abruptly turning manic or hypomanic; nor patients currently hypomanic or manic turning abruptly depressed). Many clinicians consider antiepileptic mood stabilizers to be the preferred category of medications for the treatment of such patients. Valproate appears to be a potentially fruitful medication to study in these dual diagnosis patients due to preliminary evidence demonstrating its anticraving efficacy.

Abstract
PURPOSE To evaluate the potential use of carbamazepine, gabapentin, and nitrous oxide as alternatives to symptom-triggered benzodiazepine administration for the treatment of alcohol withdrawal syndrome (AWS), a literature review was conducted. SUMMARY English-language reports of clinical trials of these agents in AWS, particularly trials that compared them with benzodiazepines or anticonvulsants or used them as benzodiazepine-sparing therapy, were reviewed. Six randomized, double-blind trials compared carbamazepine with agents used in the United States. The results suggest that carbamazepine may be useful for this indication, particularly in outpatient settings, although adverse effects and drug interactions may limit its usefulness. The role of gabapentin is unclear because of the lack of randomized, double-blind, controlled trials and the conflicting results of existing case series and open-label trials. Two poorly designed trials of nitrous oxide had conflicting results. CONCLUSION Because of the limitations in evidence accrued so far, the routine use of carbamazepine and gabapentin for the treatment of AWS cannot be recommended, and nitrous oxide should be avoided for this indication.

Abstract
Alcohol withdrawal syndrome (AWS) can be a life-threatening condition affecting some alcohol-dependent patients who abruptly discontinue or decrease their alcohol consumption. The main objectives of the clinical management of AWS include: to decrease the severity of symptoms, prevent more severe withdrawal clinical manifestations and facilitate entry of the patient into a treatment program in order to attempt to achieve and maintain long-term abstinence from alcohol. At present, benzodiazepines represent the drugs of choice in the treatment of AWS. However, in line with the possible side effects and addictive properties related to benzodiazepine use, there is growing evidence to suggest that non-benzodiazepine GABAergic compounds represent promising medications in the treatment of alcohol-dependent patients. This review focuses on research into non-benzodiazepine GABAergic medications for the treatment of AWS. Among them, carbamazepine, gabapentin and valproic acid are the most studied. The studies on carbamazepine seem to be the most compelling. Preliminary data have also suggested the possible utility of baclofen and topiramate, although further evidence is needed. The promising results in terms of both safety and efficacy are reported. However, we also note the need of more methodologically controlled studies on a greater number of patients, involving more complicated forms of AWS.

Abstract
Addiction to substances continues to be a significant public health concern in the United States. The following review of current pharmacological treatments discusses a range of substances: nicotine, alcohol, cocaine, and opioids. The goal is to provide an overview of currently available and new pharmacological treatments for substance use disorders, while also addressing the pharmacothera-peutic challenges remaining. The significant advances in pharmacotherapy have had limited utilization, however. For example, naltrexone for alcoholism is infrequently prescribed, buprenorphine for opiates still has relatively few qualified prescribers, and stimulants have no Food and Drug Administration-approved pharmacotherapy. These pharmacotherapies are needed, with the rate of even the relatively uncommon abuse of opiates now rising sharply.

Abstract
The advantages of alcohol detoxification treatment with combined carbamazepine and tiapride compared to benzodiazepines or clomethiazole is a lower level of sedation and lack of addictive potential. We report a case of carbamazepine intoxication with serum levels up to 19 mg/l in an otherwise healthy 45-year-old alcohol-dependent male after treatment with 600 mg carbamazepine and 600 mg tiapride per day. Medication was discontinued immediately and a purgative was administered. We were able to combat the intoxication but the assumed good tolerance of the combined treatment with carbamazepine and tiapride for alcohol detoxification still has to be proven.

Abstract
This was a retrospective study to examine the efficacy, practicability and medical safety of a combination of tiapride and unretarded (fast acting formula) carbamazepine in the treatment of alcohol withdrawal syndrome. In five hospitals using this combination for treatment of alcohol withdrawal, 540 patients who had been treated with this combination were identified. An intensive evaluation of patients files and charts was performed. Details of alcohol history and comorbid disorders were extracted from patient files. Severity of alcohol withdrawal had been assessed using the CIWA-A-Score. Gender differences and differences between patients in their first and at least second withdrawal were computed by means of variance analyses (GLM). At baseline (day 1) mean dosage given was 796 for tiapride and 543 mg for carbamazepine. A pooled analysis of the results showed that, in general, medication was well tolerated. Withdrawal symptomatology as indicated by CIWA-A scores clearly decreased over time. Although a significant number of patients had a history of alcohol withdrawal delirium (103) and epileptic seizures (151), few patients suffered from them during treatment (8 and 5, respectively). Only 24 (4.4%) patients dropped out because of lack of efficacy or change of medication, 15 (2.8%) because of side effects. No case of malignant neuroleptic syndrome was recorded. Data analysis showed gender differences and differences between patients in their first and at least second withdrawal for side effects, complications, and in some CIWA-A-scores. In general, severe complications of withdrawal syndrome were more frequent in men compared to women and in patients with repeated inpatient treatment. In line with previous research, the results from this study give further evidence that a combination of the anticonvulsant carbamazepine and tiapride is an effective and safe treatment for alcohol withdrawal treatment.

Abstract
There have been many recent developments in the pharmacological management of alcohol withdrawal and alcohol dependence. Although previous treatments had included benzodiazepines as their mainstay, the use of these agents in the alcoholic population is problematic. Benzodiazepines are themselves addictive and they may increase the risk of alcohol relapse. Non-benzodiazepine anticonvulsants such as carbamazepine, valproic acid, gabapentin, vigabatrin and topiramate have been shown to be excellent treatments of both alcohol withdrawal and the prevention of alcohol relapse. Although none of these agents have yet been approved by the FDA, there is growing evidence in the literature to support their use.

Abstract
This article provides an overview of current pharmacological treatments for alcohol, opioid, cocaine, and nicotine use disorders. Guidelines for a "patient-treatment" matching framework to physicians working with various "substance-abusing" patients are presented, as well as recommendations regarding when to initiate and discontinue pharmacotherapy. Standard and newer pharmacological treatments for substance dependence are reviewed, as well as therapies that may be especially useful when treating the patient with comorbid substance dependency and psychiatric disorders. To maximize the therapeutic benefits of substance dependency treatment, patients should be individually assessed and provided adjunctive medications as clinically indicated. Specific areas for future laboratory and/or clinical research are recommended.

Abstract
OBJECTIVES To estimate the proportion of routine clinical interventions in internal medicine that are supported by the results of randomized controlled trials or consensus amongst experienced internists. DESIGN Retrospective review of case records allowed one or more major diagnosis-intervention combination(s) to be identified for each patient. The scientific literature was searched for metaanalyses and randomized controlled trials in electronic databases that supported the specific intervention used. When support from randomized trials was lacking, possible consensus on management was sought by asking national expert panels of experienced clinicians. SETTING Department of Medicine at a Swedish teaching hospital. SUBJECTS At total of 197 consecutively admitted medical inpatients. RESULTS Fifty per cent of the diagnosis-intervention combinations (186/369) were supported by results from randomized controlled trial evidence and 34% (125/369) were supported by consensus amongst experienced clinicians. The proportion of interventions based on randomised controlled trials was highest in patients with cardiac (64%) and other circulatory diagnoses (73%). There were no important differences between sexes or between age groups. CONCLUSIONS Half of the interventions used in routine clinical practice amongst medical inpatients are supported by results from randomized controlled trials. These results refute popular claims that only a small proportion of medical interventions are supported by scientific evidence.

Abstract
Abrupt cessation of regular use of alcohol in a dependent person causes a withdrawal syndrome that may range from mild to extremely severe. Most patients require pharmacologic intervention, especially those with severe symptoms. Historically, the pharmacotherapy of alcohol withdrawal has involved a wide variety of agents. Benzodiazepines are currently preferred due to their consistently high degree of efficacy and laudable record of safety. In addition, beta blockers and clonidine are useful, as both effectively combat the hypertension and tachycardia commonly associated with withdrawal. They are ineffective as anticonvulsants; however. Opinions differ concerning the best treatment for withdrawal seizures. Prophylaxis with benzodiazepines may be all that is required, although some authors advocate the use of phenytoin for 5 days, especially in persons with a history of prior seizures during alcohol withdrawal. Once established, delirium tremens are difficult to treat. Benzodiazepines are most commonly used to provide sedation, and extremely large doses may be required. Careful clinical assessment is essential to the proper treatment of patients undergoing alcohol withdrawal since the coexistence of medical problems may complicate the condition.

Abstract
1. Efficacy and safety of tetrabamate and chlordiazepoxide in the treatment of the acute or Primary Alcohol Withdrawal Syndrome (PAWS) were assessed during a randomized double blind clinical trial, carried out on sixty male alcoholic in-patients. 2. The two drugs were administered four times a day in double dummy conditions, according to a fixed-flexible decreasing dosage schedule (six days basic regimen). 3. Drug efficacy was measured daily throughout the study period using a battery of standard instruments for collecting quantitative clinical, behavioral, psychopathological and laboratory data. Side effects were daily recorded. 4. Tetrabamate was found to be as efficient as chlordiazepoxide in reducing the intensity of the PAWS, improving sleep and vital signs rapidly and alleviating anxiety progressively. 5. Tetrabamate was found particularly beneficial for severe tremor. Psychomotor and mood scores consistently favored tetrabamate, suggesting psychoanaleptic properties of this compound (increased diurnal vigilance). 6. Side effects were minimal with tetrabamate and generally of weak intensity with chlordiazepoxide. 7. The results of this study indicate that tetrabamate may represent a new alternative drug of choice for the therapy of the acute alcohol withdrawal syndrome.

Abstract
Ethanol, a highly lipid-soluble compound, appears to exert its effects through interactions with the cell membrane. Cell membrane alterations indirectly affect the functioning of membrane-associated proteins, which function as channels, carriers, enzymes and receptors. For example, studies suggest that ethanol exerts an effect upon the gamma-aminobutyric acid (GABA)-benzodiazepine-chloride ionophore receptor complex, thereby accounting for the biochemical and clinical similarities between ethanol, benzodiazepines and barbiturates. The patient with acute ethanol poisoning may present with symptoms ranging from slurred speech, ataxia and incoordination to coma, potentially resulting in respiratory depression and death. At blood alcohol concentrations of greater than 250 mg% (250 mg% = 250 mg/dl = 2.5 g/L = 0.250%), the patient is usually at risk of coma. Children and alcohol-naive adults may experience severe toxicity at blood alcohol concentrations less than 100 mg%, whereas alcoholics may demonstrate significant impairment only at concentrations greater than 300 mg%. Upon presentation of a patient suspected of acute ethanol poisoning, cardiovascular and respiratory stabilisation should be assured. Thiamine (vitamin B1) and then dextrose should be administered, and the blood alcohol concentration measured. Subsequent to stabilisation, alternative aetiologies for the signs and symptoms observed should be considered. There are presently no agents available for clinical use that will reverse the acute effects of ethanol. Treatment consists of supportive care and close observation until the blood alcohol concentration decreases to a non-toxic level. In the non-dependent adult, ethanol is metabolised at the rate of approximately 15 mg%/hour. Haemodialysis may be considered in cases of a severely ill child or comatose adult. Follow-up may include referral for counselling for alcohol abuse, suicide attempts, or parental neglect (in children). The ethanol withdrawal syndrome may be observed in the ethanol-dependent patient within 8 hours of the last drink, with blood alcohol concentrations in excess of 200 mg%. Symptoms consist of tremor, nausea and vomiting, increased blood pressure and heart rate, paroxysmal sweats, depression, and anxiety. Alterations in the GABA-benzodiazepine-chloride receptor complex, noradrenergic overactivity, and hypothalamic-pituitary-adrenal axis stimulation are suggested explanations for withdrawal symptomatology.(ABSTRACT TRUNCATED AT 400 WORDS)

Abstract
The use of pharmacologic intervention in the management of alcohol withdrawal syndrome is briefly presented. The use of carbamazepine, a tricyclic anticonvulsant with clinical efficacy in depressive illness, in alcohol withdrawal treatment is reviewed. A comparative analysis between carbamazepine and major drugs used in alcohol withdrawal syndrome is made. This includes the evaluation of both clinical advantages and disadvantages in addition to identification of drug adverse reaction and interaction with alcohol. The mechanism of action of carbamazepine is also examined. Carbamazepine appears to possess a useful pharmacotherapeutic potential in the management of acute alcohol withdrawal syndrome, and its use in long-term treatment is suggested.

Abstract
The effects of phenobarbital (PB) and carbamazepine (CZ) on the ethanol withdrawal reaction in the rat were investigated in a blind study including an untreated control group. Physical ethanol dependence was established by intragastric intubation during a 4-day period. Both the degree of intoxication and the withdrawal reaction were assessed by standardised assessment instruments. Treatment with PB (40-60 mg/kg) and CZ (80-120 mg/kg) was initiated 10 h after the last ethanol dose and continued during the first 24 h of withdrawal. Serum concentrations of the drugs were measured. Both PB and CZ significantly reduced the ethanol withdrawal reaction compared to controls, and PB was significantly more effective than CZ. The degree of drug intoxication signs assessed by the same rating scale as the degree of ethanol intoxication indicated that maximum tolerable drug doses were used. PB probably exerts its treatment effect through the mechanism of cross dependence with ethanol, while CZ may exert a more specific effect on limbic structures responsible for central nervous system excitability.

Abstract
Seventy-two hospitalized patients with alcohol withdrawal symptoms were treated with either carbamazepine (Tegretol) or barbital ( Diemal ) in a randomized, double-blind trial. The dose of trial medication as well as the duration of treatment was individual, corresponding to the conventional treatment schedule. During the trial period daily records were kept of target withdrawal symptoms, global evaluation, the patient's subjective feeling and unwanted effects. Sixty patients completed the treatment successfully. The two treatment groups were homogeneous as regards patient characteristics, pre-treatment disease severity and drop-out rate. No statistically significant differences were found in efficacy between the two treatments, and both drugs were well tolerated. It is concluded that carbamazepine is a valuable alternative drug in the treatment of mild and moderate alcohol withdrawal symptoms.
