The "temporary recommendation for use" (TRU) is a French novel regulatory measure for off-label drug. The first TRU to be issued by the French drug agency (in March 2014) pertained to the off-label use of baclofen for alcohol dependence (AD). We performed a questionnaire-based survey of the on-the-ground application of the baclofen TRU among community pharmacies in northern France. A pharmacist from 70 of the 219 pharmacies contacted (response rate: 32.0%) completed the questionnaire. The mean ± standard deviation number of off-label baclofen prescriptions for AD was 2...

Glioblastoma multiforme (GBM) is the most common and aggressive malignancy of the central nervous system. Treatment usually involves a combination of surgical resection, chemotherapy, and radiotherapy, but ultimately this condition is incurable. Besides the dismal prognosis of GBM, financial factors have also presented challenges for advancing treatments. Taking into consideration the high cost of developing new anticancer drugs as well as the fact that GBM is a rare disease, thus further limiting financial incentive for drug development, it becomes obvious that there has been growing interest for repurposing candidates...

Alcohol, nicotine and cannabis are among the most commonly used drugs. A prolonged and combined use of these substances can alter normal brain wiring in different ways depending on the consumed cocktail mixture. Brain connectivity alterations and their change with time can be assessed using functional magnetic resonance imaging (fMRI) because of its spatial and temporal content. Here, we estimated dynamic functional network connectivity (dFNC) as derived from fMRI data to investigate the effects of single or combined use of alcohol, nicotine and cannabis...

For the treatment of metastatic bone cancer, local delivery of therapeutic agents is preferred compared to systemic administration. Delivery of an anti-cancer drug and a protein that helps in bone regeneration simultaneously is a challenging approach. In this study, a nanoparticulate carrier which delivers a protein and an anti-cancer drug is reported. Bovine serum albumin (BSA) as a model protein was loaded into hydroxyapatite (HA) nanoparticles (NPs) and methotrexate (MTX) conjugated to poly(vinyl alcohol) was coated onto BSA-loaded HA NPs...

People who inject drugs (PWID) are at increased risk of HIV infection. Although methadone maintenance therapy can help lower this risk, many methadone patients continue to engage in HIV risk behaviors, especially patients who use cocaine and alcohol. The purpose of the current study was to investigate relations between alcohol use disorders and HIV risk behavior in 239 cocaine-dependent methadone patients participating in a randomized controlled trial of a behavioral intervention to promote cocaine abstinence...

The liver is an essential organ for the detoxification of exogenous xenobiotics, drugs and toxic substances. The incidence rate of non-alcoholic liver injury increases due to dietary habit change and drug use increase. Our previous study demonstrated that Ecklonia stolonifera (ES) formulation has hepatoprotective effect against alcohol-induced liver injury in rat and tacrine-induced hepatotoxicity in HepG2 cells. This present study was designated to elucidate hepatoprotective effects of ES formulation against carbon tetrachloride (CCl₄)-induced liver injury in Sprague Dawley rat...

The pregnane X receptor (PXR, NR1I2) is a xenobiotic-sensing nuclear receptor that modulates the metabolic response to drugs and toxic agents. Both PXR activation and deficiency promote hepatic triglyceride accumulation, a hallmark feature of alcoholic liver disease (ALD). However, the molecular mechanism of PXR-mediated activation of ethanol (EtOH)-induced steatosis is unclear. Here, using male wild type (WT) and Pxr-null mice we examined PXR-mediated regulation of chronic EtOH-induced hepatic lipid accumulation and hepatotoxicity...

Alcohol and nicotine are two of the most frequently abused drugs, with their comorbidity well described. Previous data show that chronic exposure to nicotine upregulates high-affinity nicotinic acetylcholine receptors (nAChRs) in several brain areas. Effects of ethanol on specific brain nAChR subtypes within the mesolimbic dopaminergic (DA) pathway may be a key element in the comorbidity of ethanol and nicotine. However, it is unknown how alcohol affects the abundance of these receptor proteins. In the present study, we measured the effect of acute binge ethanol on nAChR α4 subunit levels in the prefrontal cortex (PFC), nucleus accumbens (NAc), ventral tegmental area (VTA), and amygdala (Amg) by western blot analysis using a knock-in mouse line, generated with a normally functioning α4 nAChR subunit tagged with yellow fluorescent protein (YFP)...

PURPOSE: Evidence suggests that a significant minority of individuals who undergo Roux-en-Y gastric bypass (RYGB) experience problematic alcohol and substance use following surgery. However, little research has examined characteristics, drinking patterns, and possible risk factors within this population. To provide descriptive information of a sample of adults with self-identified alcohol use problems following bariatric surgery, this study examined (1) alcohol and substance use symptoms using standardized assessments, (2) current and past psychiatric comorbidity, (3) subjective changes in alcohol sensitivity following surgery, and (4) specific patterns of alcohol use prior to and following bariatric surgery...

Nanoparticle-based theranostic agents have emerged as a new paradigm in nanomedicine field for integration of multimodal imaging and therapeutic functions within a single platform. However, the clinical translation of these agents is severely limited by the complexity of fabrication, long-term toxicity of the materials, and unfavorable biodistributions. Here we report an extremely simple and robust approach to develop highly versatile and biocompatible theranostic poly(vinyl alcohol)-porphyrin nanoparticles (PPNs)...

In addiction, risk factors for craving and use include stress and drug-related cues. Stress and cues have additive or more-than-additive effects on drug seeking in laboratory animals, but, surprisingly, seem to compete with one another (ie, exert less-than-additive effects) in human laboratory studies of craving. We sought heretofore elusive evidence that human drug users could show additive (or more-than-additive) effects of stress and cues on craving, using ecological momentary assessment (EMA). Outpatients (N=182) maintained on daily buprenorphine or methadone provided self-reports of stress, craving, mood, and behavior on electronic diaries for up to 16 weeks...

BACKGROUND: A recent clinical trial found that pharmacological blockade of V1b receptors reduces alcohol relapse in alcohol-dependent patients. SSR149415 is a selective V1b receptor antagonist that has potential for development as an alcohol dependency treatment. In this study, we investigated whether SSR149415 alone or in combination with the mu-opioid receptor [MOP-r] antagonist naltrexone (NTN) would alter excessive alcohol drinking in mice. METHODS: Both sexes of C57BL/6J (B6) mice were subjected to a chronic intermittent access (IA) drinking paradigm (two-bottle choice, 24-h access every other day) for 3 weeks...

BACKGROUND: Alcoholic hepatitis is a form of alcoholic liver disease, characterised by steatosis, necroinflammation, fibrosis, and potential complications to the liver disease. Typically, alcoholic hepatitis presents in people between 40 and 50 years of age. Alcoholic hepatitis can be resolved if people abstain from drinking, but the risk of death will depend on the severity of the liver damage and abstinence from alcohol. Glucocorticosteroids are used as anti-inflammatory drugs for people with alcoholic hepatitis...

Mu opioid receptors (MORs) are widely distributed throughout brain reward circuits and their role in drug and social reward is well established. Substantial evidence has implicated MOR and the endogenous opioid system in alcohol reward, but circuit mechanisms of MOR-mediated alcohol reward and intake behavior remain elusive, and have not been investigated by genetic approaches. We recently created conditional knockout (KO) mice targeting the Oprm1 gene in GABAergic forebrain neurons. These mice (Dlx-MOR KO) show a major MOR deletion in the striatum, whereas receptors in midbrain (including the Ventral Tegmental Area or VTA) and hindbrain are intact...

Approved pharmacological treatments for alcohol use disorder are limited in their effectiveness, and new drugs that can easily be translated into the clinic are warranted. One of those candidates is oxytocin because of its interaction with several alcohol-induced effects. Alcohol dependent rats as well as postmortem brains of human alcoholics and controls were analyzed for the expression of the oxytocin system by qRT-PCR, in situ hybridization, receptor autoradiography ([(125)I]-OVTA binding) and immunohistochemistry...
