(oxybate OR ghb) AND alcohol

Karen E van den Hondel, Anne Linde Saaltink, Peter Paul M Bender
BACKGROUND: Forensic physicians are responsible for first-line medical care of detainees (individuals held in custody) in the police station. The Dutch police law contains a 'duty of care', which gives the police responsibility for the apparent mentally ill and/or confused people they encounter during their work. The police can ask a forensic physician to do a primary psychiatric assessment of any apparent mentally ill detainee. The forensic physician determines if the apparent mentally ill behavior of the detainee is due to a somatic illness, or has a psychiatric cause for which the detainee needs admission to a psychiatric hospital...

Gamma-hydroxybutyrate (GHB or Xyrem(R)) is frequently used in humans for several clinical indications, including anesthesia, narcolepsy/cataplexy, and alcohol-withdrawal symptoms. Pharmacological effects induced in the brain by therapeutic doses of Xyrem(R) are generally GABAergic-dependent. These effects allow sedation, stress/anxiety reduction, deep sleep induction, decrease of neuroinflammation, and neuroprotection. Furthermore, Xyrem(R) promotes the expression of pivotal genes reducing toxic proteinopathies, as demonstrated in laboratory animal models...

Experimental studies on the impairing effects of drugs of relevance to driving-related performance published between 1998 and 2015 were reviewed. Studies with on-the-road driving, driving simulators, and performance tests were included for benzodiazepines and related drugs, cannabis, opioids, stimulants, GHB, ketamine, antihistamines, and antidepressants. The findings in these experimental studies were briefly discussed in relation to a review of epidemiological studies published recently. The studies mainly concluded that there may be a significant psychomotor impairment after using benzodiazepines or related drugs, cannabis, opioids, GHB, or ketamine...

The treatment of alcohol use disorder (AUD) with sodium oxybate (SMO) or gamma-hydroxybutyric acid (GHB) was introduced in Italy and Austria more than 20 years and 15 years ago, respectively, and it is now widely employed to treat alcohol withdrawal syndrome (AWS) and to maintain alcohol abstinence. These indications derive from its similar structure to the inhibitory neurotransmitter γ-amino-butyric acid (GABA), exerting an ethanol-mimicking effect, because it binds to GABAB receptors. Craving for, and abuse of, SMO remain a controversial issue; even though these unfavorable effects are evident in poly-drug addicted patients and in those with psychiatric diagnosis of borderline personality disorder...

The treatment of alcohol use disorder still remains a challenge. The efficacy of the combined pharmacological treatment for alcohol use disorder has been widely investigated with controversial results. The aim of our case series was to investigate the effect of nalmefene in patients not responding to sodium oxybate therapy. We describe seven cases of consecutive patients affected by alcohol use disorder, and treated with sodium oxybate (50 mg/kg per day) who did not achieve complete alcohol abstinence after at least one month of pharmacological treatment...

Legislative limits for driving under the influence of 20 non-alcohol drugs were introduced in Norway in February 2012. Per se limits corresponding to blood alcohol concentrations (BAC) of 0.2g/kg were established for 20 psychoactive drugs, and limits for graded sanctions corresponding to BACs of 0.5 and 1.2g/kg were determined for 13 of these drugs. This new legislation made it possible for the courts to make sentences based on the analytical results, similar to the situation for alcohol. To ensure that the reported concentration is as least as high as the true concentration, with a 99% safety level, safety margins had to be calculated for each of the substances...

BACKGROUND: Research in adults shows that substance dependent individuals demonstrate attentional bias (AB) for substance-related stimuli. This study investigated the role of AB in adolescents diagnosed with alcohol, cannabis, amphetamine or GHB dependency on entering therapy and six months later, and the role of executive control (EC) as a moderator of the relationship between problem severity and AB. METHODS: Seventy-eight young substance-dependent (SD) patients (mean age=19...

Gamma-hydroxybutyrate (GHB) is a short chain fatty acid endogenously produced within the central nervous system (CNS) and acts as a precursor and metabolite of the inhibitory neurotransmitter γ-aminobutyric acid (GABA). Although, it is an illegal recreational drug of abuse, its sodium salt (sodium oxybate) has been utilized as a medication for a number of medical conditions. The first aim of this review was to focus on current applications of sodium oxybate for the treatment of narcolepsy, with a particular emphasis on the key symptoms of this disorder: cataplexy and excessive daytime sleepiness (EDS)...

AIMS: γ-Hydroxybutyrate (GHB) is used as a treatment for narcolepsy and alcohol withdrawal and as a recreational substance. Nevertheless, there are limited data on the pharmacokinetics and pharmacokinetic-pharmacodynamic relationships of GHB in humans. We characterized the pharmacokinetic profile and exposure-psychotropic effect relationship of GHB in humans. METHODS: Two oral doses of GHB (25 and 35 mg kg(-1) ) were administered to 32 healthy male subjects (16 for each dose) using a randomized, placebo-controlled, cross-over design...

γ-Hydroxybutyric acid (GHB) is a powerful central nervous system depressant, currently used in medicine for the treatment of narcolepsy and alcohol dependence. In recent years, it has gained popularity among illegal club drugs, mainly because of its euphoric effects as well as doping agent and date rape drug. The purpose of the present work was the development of a rapid analytical method for the analysis of GHB in innovative biological matrices, namely dried blood spots (DBSs) and dried urine spots (DUSs)...

BACKGROUND: Many patients present to emergency departments (EDs) with an altered state of consciousness. Fast exclusion of gamma hydroxybutyrate (GHB)-associated intoxication in these patients may optimize diagnostic and therapeutic algorithms and decisions in the ED. METHODS: Between January and March 2014, a novel enzymatic test system was used to quantify GHB in blood and urine samples of suspected intoxicated patients in the ED of the University Hospital. The underlying causes for suspected intoxication and the diagnostic and therapeutic measures were documented and analysed retrospectively...

Drug facilitated sexual assault (DFSA) can be defined as sexual activity occurring whereby the victim is incapacitated by drugs and/or alcohol and thereby unable to consent. A new wave of designer drugs is emerging in the community at large and one group, the synthetic cathinones, is described in this study. Analyzing urine samples from reported sexual assaults submitted to the University of Miami Toxicology Lab in 2013 determined that methylone has become a popular drug encountered in these cases. Derivatization of these synthetic cathinones enabled a validated a qualitative method to identify ten different designer drugs...

Almost 10% of the world's population is affected by alcohol use disorder (AUD). The combination between psychosocial intervention and pharmacological treatment seems to be the most effective approach for patients affected by AUD. Among effective drugs useful in the treatment of AUD, GABAB-ergic medications have been tested with encouraging results (i.e. sodium oxybate, baclofen, gabapentin, pregabalin and tiagabine). The present review will summarize available data on these medications.

The illicit recreational drug of abuse, γ-hydroxybutyrate (GHB) is a potent central nervous system depressant and is often encountered during forensic investigations of living and deceased persons. The sodium salt of GHB is registered as a therapeutic agent (Xyrem®), approved in some countries for the treatment of narcolepsy-associated cataplexy and (Alcover®) is an adjuvant medication for detoxification and withdrawal in alcoholics. Trace amounts of GHB are produced endogenously (0.5-1.0 mg/L) in various tissues, including the brain, where it functions as both a precursor and a metabolite of the major inhibitory neurotransmitter γ-aminobutyric acid (GABA)...

γ-Hydroxybutyric acid (GHB) is a recreational drug, a clinically prescribed drug in narcolepsy and alcohol dependence, and an endogenous substance that binds to both high- and low-affinity sites in the brain. For studying the molecular mechanisms and the biologic role of the GHB high-affinity binding sites, ligands with high and specific affinity are essential. The conformationally restricted GHB analog HOCPCA (3-hydroxycyclopent-1-enecarboxylic acid) is one such compound. The objective of this study was to investigate the transport of HOCPCA across the blood-brain barrier in vitro and in vivo and to investigate the hypothesis that HOCPCA, like GHB, is a substrate for the monocarboxylate transporters (MCTs)...

OBJECTIVE: The treatment of alcohol dependence (AD) with sodium oxybate (SMO) was introduced in Italy and Austria more than 20 years and 15 years ago respectively, and it is now widely employed. In addition to the data obtained from clinical trials, little information is available on specific clinical practices. Thus, the aim of this study was to present and discuss the results of a consensus meeting held after twenty years of using SMO in clinical practice in Italy. MATERIALS AND METHODS: A validated questionnaire study was conducted to investigate the modalities of treatment of AD with SMO currently used in Italy...
