Review
BACKGROUND
Cocaine is a psychostimulant used by approximately 0.4% of the general population worldwide. Cocaine dependence is a chronic mental disorder characterised by the inability to control cocaine use and a host of severe medical and psychosocial complications. There is current no approved pharmacological treatment for cocaine dependence. Some researchers have proposed disulfiram, a medication approved to treat alcohol use disorder. This is an update of a Cochrane review first published in 2010.
OBJECTIVES
To evaluate the efficacy and safety of disulfiram for the treatment of cocaine dependence.
SEARCH METHODS
We updated our searches of the following databases to August 2022: the Cochrane Drugs and Alcohol Group Specialised Register, CENTRAL, MEDLINE, Embase, CINAHL, and PsycINFO. We also searched for ongoing and unpublished studies via two trials registries. We handsearched the references of topic-related systematic reviews and included studies. The searches had no language restrictions.
SELECTION CRITERIA
We included randomised controlled trials that evaluated disulfiram alone or associated with psychosocial interventions versus placebo, no intervention, other pharmacological interventions, or any psychosocial intervention for the treatment of cocaine dependence.
DATA COLLECTION AND ANALYSIS
We used standard methodological procedures expected by Cochrane.
MAIN RESULTS
Thirteen studies (1191 participants) met our inclusion criteria. Disulfiram versus placebo or no treatment Disulfiram compared to placebo may increase the number of people who are abstinent at the end of treatment (point abstinence; risk ratio (RR) 1.58, 95% confidence interval (CI) 1.05 to 2.36; 3 datasets, 142 participants; low-certainty evidence). However, compared to placebo or no pharmacological treatment, disulfiram may have little or no effect on frequency of cocaine use (standardised mean difference (SMD) -0.11 standard deviations (SDs), 95% CI -0.39 to 0.17; 13 datasets, 818 participants), amount of cocaine use (SMD -0.00 SDs, 95% CI -0.30 to 0.30; 7 datasets, 376 participants), continuous abstinence (RR 1.23, 95% CI 0.80 to 1.91; 6 datasets, 386 participants), and dropout for any reason (RR 1.20, 95% CI 0.92 to 1.55; 14 datasets, 841 participants). The certainty of the evidence was low for all these outcomes. We are unsure about the effects of disulfiram versus placebo on dropout due to adverse events (RR 12.97, 95% CI 0.77 to 218.37; 1 study, 67 participants) and on the occurrence of adverse events (RR 3.00, 95% CI 0.35 to 25.98), because the certainty of the evidence was very low for these outcomes. Disulfiram versus naltrexone Disulfiram compared with naltrexone may reduce the frequency of cocaine use (mean difference (MD) -1.90 days, 95% CI -3.37 to -0.43; 2 datasets, 123 participants; low-certainty evidence) and may have little or no effect on amount of cocaine use (SMD 0.12 SDs, 95% CI -0.27 to 0.51, 2 datasets, 123 participants; low-certainty evidence). We are unsure about the effect of disulfiram versus naltrexone on dropout for any reason (RR 0.86, 95% CI 0.56 to 1.32, 3 datasets, 131 participants) and dropout due to adverse events (RR 0.50, 95% CI 0.07 to 3.55; 1 dataset, 8 participants), because the certainty of the evidence was very low for these outcomes.
AUTHORS' CONCLUSIONS
Our results show that disulfiram compared to placebo may increase point abstinence. However, disulfiram compared to placebo or no pharmacological treatment may have little or no effect on frequency of cocaine use, amount of cocaine use, continued abstinence, and dropout for any reason. We are unsure if disulfiram has any adverse effects in this population. Caution is required when transferring our results to clinical practice.

Review
OBJECTIVES
Alcohol-related concerns commonly present to the emergency department (ED), with a subset of individuals experiencing the symptoms of an alcohol use disorder (AUD). As such, examining the efficacy of pharmacological anti-craving treatment for AUD in the ED is of increasing interest. The objective of this systematic review was to evaluate the direct evidence assessing the efficacy of providing anti-craving medications for AUD treatment in the ED.
METHODS
A systematic search was conducted according to the patient-intervention-control-outcome question: (P) adults (≥18 years old) presenting to the ED with an AUD (including suspected AUD); (I) anti-craving medications (i.e., naltrexone, acamprosate, gabapentin); (C) no prescription or placebo; (O) reduction of repeat ED visits, engagement in addiction services, reductions in heavy drinking days, reductions in any drinking and amount consumed (or abstinence), and in relapse. Two reviewers independently assessed articles for inclusion and conducted risk of bias assessments for included studies.
RESULTS
From 143 potentially relevant articles, 6 met inclusion criteria: 3 clinical trials, and 3 case studies. The clinical trials identified evaluated oral versus extended-release naltrexone, monthly extended-release naltrexone injections, and disulfiram. Both oral and extended-release naltrexone resulted in decreased alcohol consumption. Monthly extended-release naltrexone injections resulted in significant improvements in drinking and quality of life. Although out of scope, the disulfiram studies identified did not result in an improvement in drinking in comparison to no medication.
CONCLUSIONS
Overall, there are few studies directly examining the efficacy of anti-craving medications for AUD in the ED, although the limited evidence that exists is supportive of naltrexone pharmacotherapy, particularly extended-release injection formulation. Additional randomized controlled trials are necessary for substantive direct evidence on anti-craving medication initiation in the ED.

Meta-Analysis Review
BACKGROUND
Harmful alcohol use is defined as unhealthy alcohol use that results in adverse physical, psychological, social, or societal consequences and is among the leading risk factors for disease, disability and premature mortality globally. The burden of harmful alcohol use is increasing in low- and middle-income countries (LMICs) and there remains a large unmet need for indicated prevention and treatment interventions to reduce harmful alcohol use in these settings. Evidence regarding which interventions are effective and feasible for addressing harmful and other patterns of unhealthy alcohol use in LMICs is limited, which contributes to this gap in services.
OBJECTIVES
To assess the efficacy and safety of psychosocial and pharmacologic treatment and indicated prevention interventions compared with control conditions (wait list, placebo, no treatment, standard care, or active control condition) aimed at reducing harmful alcohol use in LMICs.
SEARCH METHODS
We searched for randomized controlled trials (RCTs) indexed in the Cochrane Drugs and Alcohol Group (CDAG) Specialized Register, the Cochrane Clinical Register of Controlled Trials (CENTRAL) in the Cochrane Library, PubMed, Embase, PsycINFO, CINAHL, and the Latin American and Caribbean Health Sciences Literature (LILACS) through 12 December 2021. We searched clinicaltrials.gov, the World Health Organization International Clinical Trials Registry Platform, Web of Science, and Opengrey database to identify unpublished or ongoing studies. We searched the reference lists of included studies and relevant review articles for eligible studies.
SELECTION CRITERIA
All RCTs comparing an indicated prevention or treatment intervention (pharmacologic or psychosocial) versus a control condition for people with harmful alcohol use in LMICs were included.
DATA COLLECTION AND ANALYSIS
We used standard methodological procedures expected by Cochrane.
MAIN RESULTS
We included 66 RCTs with 17,626 participants. Sixty-two of these trials contributed to the meta-analysis. Sixty-three studies were conducted in middle-income countries (MICs), and the remaining three studies were conducted in low-income countries (LICs). Twenty-five trials exclusively enrolled participants with alcohol use disorder. The remaining 51 trials enrolled participants with harmful alcohol use, some of which included both cases of alcohol use disorder and people reporting hazardous alcohol use patterns that did not meet criteria for disorder. Fifty-two RCTs assessed the efficacy of psychosocial interventions; 27 were brief interventions primarily based on motivational interviewing and were compared to brief advice, information, or assessment only. We are uncertain whether a reduction in harmful alcohol use is attributable to brief interventions given the high levels of heterogeneity among included studies (Studies reporting continuous outcomes: Tau² = 0.15, Q =139.64, df =16, P<.001, I² = 89%, 3913 participants, 17 trials, very low certainty; Studies reporting dichotomous outcomes: Tau²=0.18, Q=58.26, df=3, P<.001, I² =95%, 1349 participants, 4 trials, very low certainty). The other types of psychosocial interventions included a range of therapeutic approaches such as behavioral risk reduction, cognitive-behavioral therapy, contingency management, rational emotive therapy, and relapse prevention. These interventions were most commonly compared to usual care involving varying combinations of psychoeducation, counseling, and pharmacotherapy. We are uncertain whether a reduction in harmful alcohol use is attributable to psychosocial treatments due to high levels of heterogeneity among included studies (Heterogeneity: Tau² = 1.15; Q = 444.32, df = 11, P<.001; I²=98%, 2106 participants, 12 trials, very low certainty). Eight trials compared combined pharmacologic and psychosocial interventions with placebo, psychosocial intervention alone, or another pharmacologic treatment. The active pharmacologic study conditions included disulfiram, naltrexone, ondansetron, or topiramate. The psychosocial components of these interventions included counseling, encouragement to attend Alcoholics Anonymous, motivational interviewing, brief cognitive-behavioral therapy, or other psychotherapy (not specified). Analysis of studies comparing a combined pharmacologic and psychosocial intervention to psychosocial intervention alone found that the combined approach may be associated with a greater reduction in harmful alcohol use (standardized mean difference (standardized mean difference (SMD))=-0.43, 95% confidence interval (CI): -0.61 to -0.24; 475 participants; 4 trials; low certainty). Four trials compared pharmacologic intervention alone with placebo and three with another pharmacotherapy. Drugs assessed were: acamprosate, amitriptyline, baclofen disulfiram, gabapentin, mirtazapine, and naltrexone. None of these trials evaluated the primary clinical outcome of interest, harmful alcohol use. Thirty-one trials reported rates of retention in the intervention. Meta-analyses revealed that rates of retention between study conditions did not differ in any of the comparisons (pharmacologic risk ratio (RR) = 1.13, 95% CI: 0.89 to 1.44, 247 participants, 3 trials, low certainty; pharmacologic in addition to psychosocial intervention: RR = 1.15, 95% CI: 0.95 to 1.40, 363 participants, 3 trials, moderate certainty). Due to high levels of heterogeneity, we did not calculate pooled estimates comparing retention in brief (Heterogeneity: Tau² = 0.00; Q = 172.59, df = 11, P<.001; I = 94%; 5380 participants; 12 trials, very low certainty) or other psychosocial interventions (Heterogeneity: Tau² = 0.01; Q = 34.07, df = 8, P<.001; I = 77%; 1664 participants; 9 trials, very low certainty). Two pharmacologic trials and three combined pharmacologic and psychosocial trials reported on side effects. These studies found more side effects attributable to amitriptyline relative to mirtazapine, naltrexone and topiramate relative to placebo, yet no differences in side effects between placebo and either acamprosate or ondansetron. Across all intervention types there was substantial risk of bias. Primary threats to validity included lack of blinding and differential/high rates of attrition.
AUTHORS' CONCLUSIONS
In LMICs there is low-certainty evidence supporting the efficacy of combined psychosocial and pharmacologic interventions on reducing harmful alcohol use relative to psychosocial interventions alone. There is insufficient evidence to determine the efficacy of pharmacologic or psychosocial interventions on reducing harmful alcohol use largely due to the substantial heterogeneity in outcomes, comparisons, and interventions that precluded pooling of these data in meta-analyses. The majority of studies are brief interventions, primarily among men, and using measures that have not been validated in the target population. Confidence in these results is reduced by the risk of bias and significant heterogeneity among studies as well as the heterogeneity of results on different outcome measures within studies. More evidence on the efficacy of pharmacologic interventions, specific types of psychosocial interventions are needed to increase the certainty of these results.

INTRODUCTION
Glioblastoma (GB) is one of the most challenging central nervous system (CNS) tumors in treatment options and response, urging the development of novel management strategies. The anti-alcoholism drug, disulfiram (DS), has a potential anticancer activity, and its complex mechanism of action is assumed to be well exploited against the heterogeneous GB.
AREA COVERED
Through a systematic literature review about repositioning DS to GB treatment, an evaluation of the clinical, pharmacological, and formulation strategies is provided to specify the challenges of drug delivery and thus to advance its clinical translation. From six databases, 35 articles were selected, including case report (1); clinical trials (3); original articles mainly representing in vitro and preclinical pharmacological data, and 10 dealing with technological approaches.
EXPERT OPINION
The repositioning of DS in GB treatment is facing drug and tumor-associated limitations due to the oral drug's low bioavailability, unwanted metabolism, and inefficient delivery to brain-tumor tissue. Development strategies using molecular encapsulation of DS and the parenteral dosage forms improve the anticancer pharmacology of the drug. The development of optimized drug delivery systems (DDS) shows promise for the clinical translation of DS into GB adjuvant therapy.

BACKGROUND
Patients with psychotic disorders (PD) often have comorbid alcohol use disorder (AUD), which is typically treated pharmacologically. Up till now, no systematic review has examined the effectiveness and safety of AUD treatment in PD patients.
OBJECTIVES
This study aimed to systematically review the literature on (1) the effects of pharmacological treatments for AUD on drinking outcomes, (2) the side effects of the drugs, and (3) the effects of polypharmacy in patients with comorbid AUD and PD.
METHODS
Bibliographic searches were conducted in MEDLINE, Embase, Cochrane Central Register of Controlled Trials, and PsycINFO. At least two reviewers extracted the data, assessed the risk of bias, and performed the qualitative synthesis of the collected evidence.
RESULTS
Twelve eligible studies were identified, half being randomized controlled trials (RCTs). Three studies examined disulfiram, nine naltrexone, two acamprosate, and one nalmefene by comparing the effects of treatment to placebo, baseline, or pharmacological agents. Disulfiram and naltrexone were shown to reduce alcohol intake. Regarding acamprosate, the findings were mixed. Nalmefene decreased alcohol intake. All pharmacological agents appeared safe to use as AUD monotherapy, but cardiac events were reported when combining naltrexone and disulfiram. Nine studies had a high risk of bias, and three had some other concerns.
CONCLUSION
The studies provide tentative support for the use of naltrexone and disulfiram in this population, although combinations of pharmacological AUD treatments and other polypharmacy remain unexplored. The studies had high adherence rates that are hardly replicable in real-world settings. Thus, the findings should be confirmed in larger high quality efficacy and effectiveness RCTs with longer follow-ups.

BACKGROUND AND OBJECTIVES
Cancer morbidity and mortality rates remain high, and thus, at present, considerable efforts are focused on finding drugs with higher sensitivity against tumor cells and fewer side effects. Disulfiram (DSF), as an anti-alcoholic drug, kills the cancer cells by inducing apoptosis. Several preclinical and clinical studies have examined the potential of repurposing DSF as an anticancer treatment. This systematic review aimed to assess evidence regarding the antineoplastic activity of DSF in in vitro and in vivo models, as well as in humans.
METHODS
Two authors independently conducted this systematic review of English and Chinese articles from the PubMed, Embase, and the Cochrane Library databases up to July 2019. Eligible in vitro studies needed to include assessments of the apoptosis rate by flow cytometry using annexin V/propidium iodide, and studies in animal models and clinical trials needed to examine tumor inhibition rates, and progression-free survival (PFS) and overall survival (OS), respectively. Data were analyzed using descriptive statistics.
RESULTS
Overall, 35 studies, i.e., 21 performed in vitro, 11 based on animal models, and three clinical trials, were finally included. In vitro and animal studies indicated that DSF was associated with enhanced apoptosis and tumor inhibition rates, separately. Human studies showed that DSF prolongs PFS and OS. The greatest anti-tumor activity was observed when DSF was used as combination therapy or as a nanoparticle-encapsulated molecule. There was no noticeable body weight loss after DSF treatment, which indicated that there was no major toxicity of DSF.
CONCLUSIONS
This systematic review provides evidence regarding the anti-tumor activity of DSF in vitro, in animals, and in humans and indicates the optimal forms of treatment to be evaluated in future research.

Meta-Analysis
BACKGROUND
We aimed to determine medications' comparative efficacy and safety for adults with alcohol use disorders.
METHODS
We searched eleven electronic data sources for randomized clinical trials with at least 4 weeks of treatment reporting on alcohol consumption (total abstinence and reduced heavy drinking), dropouts, and dropouts due to adverse events. We conducted network meta-analyses using random-effects, frequentist models, and calculated summary rate ratios (RRs) with 95% confidence intervals (CIs).
RESULTS
We included 156 trials (N = 27,334). Nefazodone (RR = 2.11; 95% CI, 1.42-3.13), aripiprazole (RR = 1.97; 95% CI, 1.36-2.88), carbamazepine (RR = 1.85; 95% CI, 1.03-3.32), and nalmefene (RR = 1.17; 95% CI, 1.01-1.35) were associated with the most dropouts. Baclofen (RR = 0.83; 95% CI, 0.70-0.97) and pregabalin (RR = 0.63; 95% CI, 0.43-0.94) caused fewer dropouts than placebo. Nalmefene (RR = 3.26; 95% CI, 2.34-4.55), fluvoxamine (RR = 3.08; 95% CI, 1.59-5.94), and topiramate (RR=2.18; 95% CI, 1.36-3.51) caused more dropouts from adverse events over placebo. Gamma-hydroxy-butyrate (RR = 1.90; 95% CI, 1.03-3.53), baclofen (RR = 1.80; 95% CI, 1.39-2.34), disulfiram (RR = 1.71; 95% CI, 1.39-2.10), gabapentin (RR = 1.66; 95% CI, 1.04-2.67), acamprosate (RR = 1.33; 95% CI, 1.15-1.54), and oral naltrexone (RR = 1.15; 95% CI, 1.01-1.32) improved total abstinence over placebo (Fig. 3C). For reduced heavy drinking, disulfiram (RR = 0.19; 95% CI, 0.10-0.35), baclofen (RR = 0.72; 95% CI, 0.57-0.91), acamprosate (RR = 0.78; 95% CI, 0.70-0.86), and oral naltrexone (RR = 0.81; 95% CI, 0.73-0.90) were efficacious against placebo.
CONCLUSIONS
The current meta-analyses provide evidence that several medications for AUDs are effective and safe and encourage the expanded use of these medications in the clinical setting. Our review found that acamprosate (2-3 g/d), disulfiram (250-500 mg/d), baclofen (30 mg/d), and oral naltrexone (50 mg/d) had the best evidence for improving abstinence and heavy drinking for patients with AUD.

Review
The objective of this systematic review was to retrieve and examine published studies related to in vitro and in vivo evaluation of disulfiram for the treatment of bacterial infections. Five scientific databases (PubMed, Embase, Scopus, Web of Science, and Latin American and Caribbean Health Sciences Literature) were searched to retrieve the maximum literature regarding the study's aim. The search strategy retrieved a total of 870 studies, of which 31 were included and 19 approached disulfiram as the primary aim and 12 included it as a secondary finding from other investigational objectives. The evidence pointed out five main aspects of pre-clinical testing regarding disulfiram antibacterial activity, namely spectrum of antimicrobial action, drug combinations, intracellular studies, animal studies and bacterial targets. Findings to emerge from this study are the observed potential of disulfiram as a non-antibiotic drug being proposed as a potential drug to contribute to the treatment of bacterial diseases usually with few treatment alternatives in the context of drug resistance. We evaluated the potency and selectivity of disulfiram, which indeed until now shows potential to be explored for use as an adjunctive chemical to antimicrobial ones. Even with the level of evidence being reserved, the potential of combining disulfiram with other drugs, already used or new to be used for the treatment of mycobacterial diseases, as well as its likely immunomodulatory effect, deserve to be further investigated. Furthermore, the copper-dependent mode of action in Gram-positive bacteria is an alternative to be explored in drug design or repurposing of chemicals.

Review
BACKGROUND
Although Alcohol Use Disorder (AUD) is highly prevalent worldwide, treating this condition remains challenging. Further, potential treatments for AUD do not fully address alcohol-induced neuroadaptive changes. Understanding the effects of pharmacotherapies for AUD on the human brain may lead to tailored, more effective treatments, and improved individual clinical outcomes.
OBJECTIVES
We systematically reviewed the literature for studies investigating pharmacotherapies for AUD that included neuroimaging-based treatment outcomes. We searched the PubMed, Scielo, and PsycINFO databases up to January 2021.
STUDY ELIGIBILITY CRITERIA, PARTICIPANTS, AND INTERVENTIONS
Eligible studies included those investigating pharmacotherapies for AUD and employing functional magnetic resonance imaging (fMRI), positron emission tomography (PET), single-photon emission computed tomography (SPECT), and/or proton magnetic resonance spectroscopy (H-MRS).
STUDY APPRAISAL AND SYNTHESIS METHODS
Two independent reviewers screened studies' titles and abstracts for inclusion. Data extraction forms were shared among all the authors to standardize data collection. We gathered information on the following variables: sample size; mean age; sociodemographic and clinical characteristics; alcohol use status; study design and methodology; main neuroimaging findings and brain-regions of interest (i.e., brain areas activated by alcohol use and possible pharmacological interactions); and limitations of each study.
RESULTS
Out of 177 studies selected, 20 studies provided relevant data for the research topic. Findings indicate that: (1) Acamprosate and gabapentin may selectively modulate limbic regions and the anterior cingulate cortex; (2) Naltrexone and disulfiram effects may involve prefrontal, premotor, and cerebellar regions; (3) Pharmacotherapies acting on glutamate and GABA neurotransmission involve primarily areas underpinning reward and negative affective states, and; (4) Pharmacotherapies acting on opioid and dopamine systems may affect areas responsible for the cognitive and motor factors of AUD.
LIMITATIONS
Most of the studies were focused on naltrexone. A small number of studies investigated the action of disulfiram and gabapentin, and no neuroimaging studies investigated topiramate. In addition, the time between medication and neuroimaging scans varied widely across studies.
CONCLUSIONS
We identified key-brain regions modulated by treatments available for AUD. Some of the regions modulated by naltrexone are not specific to the brain reward system, such as the parahippocampal gyrus (temporal lobe), parietal and occipital lobes. Other treatments also modulate not specific regions of the reward system, but play a role in the addictive behaviors, including the insula and dorsolateral prefrontal cortex. The role of these brain regions in mediating the AUD pharmacotherapy response warrants investigation in future research studies.
