Filter by:Background: - Baclofen is a drug used to control muscle stiffness in people with neurological diseases. Some studies suggest that baclofen may reduce alcohol craving and use. It helps to reduce anxiety in alcoholics, which in turn can help to reduce cravings. Researchers want to see if baclofen can be a safe and effective treatment for alcoholics who have high anxiety levels. Objectives: - To see if baclofen is safe and helpful for people who have alcoholism and high anxiety levels. Eligibility: - Individuals between 21 and 65 years of age who have been diagnosed with alcoholism and anxiety issues. - Participants must not be taking anti-anxiety medication. Design: - Participants will be screened with a physical exam and medical history. Blood and urine samples will be collected. Tests of alcohol dependency and anxiety levels will also be given. - Participants will be divided into two groups. One group will take baclofen. The other group will have a placebo. - About 1 week after the screening visit, participants will have a study visit. They will answer questions about their behavior and mood. They will then start to take either baclofen or a placebo. Participants will take the study drug three times a day, every day. - After 1 week on the study drug, participants will have an overnight stay at the National Institutes of Health. They will have blood tests and answer questions about mood and behavior. They will also have tests that involve choosing to drink alcohol and answering more questions about cravings. - Participants will stop taking their study drug over a 3-day period. - A final follow-up visit will be required 1 week after the overnight study visit. Participants will receive information about other alcohol abuse treatment programs.
The goal of this project is to improve the treatment of veterans with co-occurring alcohol dependence and posttraumatic stress disorder (PTSD). The PI and co-investigators will conduct a controlled clinical trial of topiramate for the treatment of these co-occurring disorders.
Overall goal of this study is to scrutinize the relation of learning behavior and related brain activity to the development of alcohol use disorder (AUD). The researchers aim is to characterise a representative sample (200 men at age 18) with regard to learning parameters and their respective neural correlates which are thought to be indicators for the risk to develop an alcohol use disorder. As part of a large multi-center study on alcohol dependency (in Dresden & Berlin, Germany) the researchers will characterize the sample and then prospectively assess alcohol consumption and development of AUDs over a period of three years plus additional follow-ups after that period, depending on future funding. Among other hypotheses it is expected that increased activation of striatal and prefrontal brain regions by the Pavlovian-to-instrumental transfer process is related to increased risk of developing an AUD.
A total of at least 48 healthy subjects with a history of social drinking will be recruited into this single-centre, randomized, double-blind, cross-over study. Subjects will be genetically stratified to result in equal numbers of A118G 'AA' homozygotes (n=24) and A118G 'G' carriers (n=24). Subjects will participate in all three treatment periods and will be randomized to receive each of the following for 5 days: Treatment A: Placebo, Treatment B: Naltrexone (NTX) 50 mg once daily (25 mg once daily for the first two days) and Treatment C: GSK1521498 10 mg once daily. A washout period will be of at least 14 days between treatments. Subjects will return for a follow-up visit 7-10 days after the final treatment session washout period has been completed. Subjects will attend the clinical research unit on days 1, 2, 3, 4 and 5 to monitor safety and tolerability for both drugs. Subjects will attend the clinical unit on days 4 and 5 for a two day assessment, using a series of pharmacodynamic measurements known to be sensitive to the effects of GSK1521498 and/or NTX: Functional brain response to alcohol and food cues; plasma cortisol; hedonic and consummatory eating behaviors; subjective response to an ethanol challenge; experimental pain threshold; and cognitive tests of attention bias towards alcohol and food cues.
The purpose of the study is to assess the efficacy of Xylka® (baclofen) compared to placebo on continuous abstinence rate during 20 weeks of treatment, after withdrawal, in alcohol dependent patients receiving Brenda therapy sessions.
The aim of the present study is to assess the availability of cannabinoid receptors (CB1R) in the human brain. CB1R are present in everyone's brain, regardless of whether or not someone has used cannabis. The investigators will image brain cannabinoid receptors using Positron Emission Tomography (PET) imaging and the radioligand OMAR, in healthy individuals and several conditions including 1) cannabis use disorders, 2) psychotic disorders, 3) prodrome of psychotic illness and 4) individuals with a family history of alcoholism, 5) Post-Traumatic Stress Disorder 6) Opioid Use Disorder using the PET imaging agent or radiotracer, [11C]OMAR. This will allow us to characterize the number and distribution of CB1R in these conditions. It is likely that the list of conditions will be expanded after the collection of pilot data and as new data on cannabinoids receptor function and psychiatric disorders becomes available. Those in the cannabis us disorder arm of the study will have a PET scan on at least three occasions: once while smoking as usual, once after 48-hours of abstinence from cannabis, and a final time after 4 weeks of abstinence. Additional scans may be conducted within the 4 weeks and the last scan may be conducted well beyond 4 weeks. Similarly, while most schizophrenia patients may get scanned just once, a subgroup of patients may get scanned more than once. For example to tease out the effects of medications, unmedicated patients may get scanned while unmedicated and again after treatment with antipsychotic medications. Similarly prodromes may get scanned while in the prodromal stage off medications, on medications and after conversion to schizophrenia.
The aim of the present study is to conduct a human trial of [C-11]OMAR, a new PET imaging agent for the brain cannabinoid type 1 receptors (CB1), to determine its pharmacokinetics and binding characteristics.
In this study we propose to study 24 unmedicated abstinent alcohol dependent patients, 24 obese individuals and 24 individually matched healthy control subjects and determine Norepinephrine Transporter (NET) expression in vivo using (S,S)-[11C]MRB and PET.
To explore the effectiveness and biobehavioural basis of baclofen in improving treatment outcomes for alcohol dependence in people with or without alcoholic cirrhosis in a double-blind randomised placebo-controlled trial.
The investigators goal is to pilot a substance use-related brief intervention (BI) for youth with chronic medical conditions, obtaining preliminary evidence of feasibility, acceptability and impacts of the approach for reducing substance use among this group.
