Craving for alcohol has been related to loss of control drinking and is a major target of biological and behavioral interventions for alcohol dependence. Our previous research has demonstrated that olanzapine (a dopamine antagonist) attenuates craving for alcohol, that a variant in the gene that expresses D4 receptors influences craving for alcohol, and that olanzapine is particularly effective at reducing craving among individuals with this variant. Pilot data from a recent 12 week trial of olanzapine indicates that olanzapine is well tolerated and that olanzapine reduces drinking, particularly among individuals with the aforementioned genetic variant. The objective of the present application is to examine the effectiveness of olanzapine (5 mg/day), as compared to olanzapine (2.5 mg/day) and a placebo control, in terms of reducing craving and alcohol use behavior among treatment seeking alcoholics. Furthermore, the present application will examine whether the effects of olanzapine on drinking outcomes are mediated by its effects on a specific putative mechanism (i.e., cue-elicited craving for alcohol) and determine whether the DRD4 VNTR polymorphism is a marker for the effectiveness of olanzapine. To that end, 202 alcohol dependent subjects will be randomly assigned to medication group and receive 12 weeks of medication. Subjects will complete follow-up assessments at 3 and 6 months after the end of the treatment. It is expected that olanzapine will significantly reduce cue-elicited craving and alcohol use behavior in a dose dependent fashion over the course of the 12 week trial and follow-up period, as compared to the placebo condition. Furthermore, it is expected that the effects of olanzapine on alcohol use behavior will be mediated by the effect of olanzapine on cue-elicited craving and that the effects of olanzapine on cue-elicited craving and alcohol use behavior will be moderated by the DRD4 VNTR, such that olanzapine will be more effective among individuals with the 7 repeat allele. The successful completion of the proposed research is expected to advance a new medication for alcohol dependence and advance genetic markers that predict the effectiveness of this medication.
This proposal is part of the INIA Stress Consortium. This study will 1. explore the contributions of lifetime trauma, recent stress, and alcohol use on stress-hormone axis disruption in treatment seeking, one-month abstinent, alcohol-dependent subjects 2. assess the combined contributions of stress-hormone axis disruption and episodic stress on the risk of prospective drinking following treatment 3. determine the role of neurosteroids in alcohol use.
Prazosin is an alpha-1 adrenergic receptor antagonist that has been used successfully in the treatment of trauma nightmares and sleep disturbance in combat veterans with PTSD, and alcohol dependence. The objective of this study is to evaluate the efficacy of prazosin (16mg) versus placebo in reducing alcohol consumption and decreasing symptoms of PTSD in patients with comorbid AD and PTSD.
The aim of the proposed pilot study is to find out whether varenicline (ChantixTM) treatment decreases alcohol use and smoking in patients with schizophrenia or schizoaffective disorder. Varenicline may also improve cognition (memory and concentration) and negative symptoms (e.g. poor attention, poverty of speech, apathy, affective flattening, anhedonia) in patients with schizophrenia and comorbid nicotine and alcohol dependence.
The proposed design is a single-group open-label trial. Qualified consenting participants with active alcohol dependence and primary or secondary anxiety disorder will receive monitored disulfiram and lorazepam, in the context of a structured Medication Management (MM) model. In weeks 9-15 lorazepam is tapered, and disulfiram is stopped at the end of week 16. Participants who achieve 4 weeks abstinence and meet criteria for a primary anxiety disorder or mood disorder may receive ancillary medication consisting FDA-approved non-benzodiazepine treatment, with specific options for each disorder described in the protocol. Participants requiring continued treatment are referred to clinical treatment in the community at week 16, and bridging prescriptions of anxiolytic/antidepressant medication may be provided. A final follow-up assessment occurs at week 28. The primary outcomes are Percent Days Abstinent (PDA) and retention in treatment. Secondary alcohol outcomes are consequences, drinks per drinking day, remission status, and time to first heavy drinking day. Anxiety outcomes are Hamilton Anxiety Scale scores and anxiety disorder diagnosis.
Two approaches for providing evidence-based substance abuse treatment (EBT), group motivational interviewing (GMI) and the In-Home-Messaging-Device (IHMD), are interventions that have the characteristic ability for increasing accessibility to evidence-based treatment among patients with substance use problems and are proposed for investigation. GMI is based on motivational interviewing, an intervention that has shown consistent significant effects in promoting treatment retention and reduced substance use among individuals with substance use disorders, and is delivered in a group format. IHMD is a user-friendly computerized Tele-mental Health communication tool that allows interaction through the telephone line between a Veteran and the health care provider in an individual's home or residential placement. The current proposal aims to determine whether GMI and IHMD lead to a significantly greater increase in treatment engagement and reduction in alcohol use compared to a treatment control condition (TCC) among Veterans with a substance use problem and a co-existing psychiatric disorder.
This study would like to test whether the combination of ondansetron and olanzapine will be superior to placebo at decreasing self-reported heavy drinking among early onset alcoholics.
The principal aim of this exploratory study is to examine whether the addition of aripiprazole to naltrexone will enhance efficacy over naltrexone alone in a 16-week randomized, placebo-controlled clinical trial, in which all subjects will be provided medical management as delivered in the COMBINE Study (Anton et al, 2006). To test whether medication treatment will reduce drinking compared to placebo treatment alone in the context of medical management and whether naltrexone plus aripiprazole will reduce drinking compared to naltrexone treatment alone in the context of medical management.
This study will determine whether naltrexone, a medicine used to treat alcoholism, can lessen the craving for alcohol during alcohol withdrawal and examine how the drug affects brain activity during alcohol infusion. People between 21 and 50 years of age who are right-handed, alcohol-dependent, and have at least one family member with a history of alcoholism, may be eligible for this study. Participants are admitted to the NIH Clinical Center for 1 month for the following procedures: Screening - Medical history, alcohol-use history and family history of alcoholism - Physical examination, psychological tests and blood tests - Medicine to lessen alcohol withdrawal symptoms, if necessary Days 1-7 - Alcohol detoxification - Medical and psychological evaluations - Assignment to naltrexone or placebo group Days 7 through 28 - Drug treatment: Take naltrexone or placebo capsule every morning - Additional alcohol-dependence treatment: Cognitive and behavioral therapies and participation in self-help groups, such as Alcoholics Anonymous - Weekly questionnaires to measure mood and desire for alcohol - Blood tests - Alcohol craving stimulation test (day 7): Subjects handle and sniff water and then their favorite alcoholic beverage. They then rate their urge to drink alcohol and their level of anxiety and their heart rate is measured. - Alcohol infusion test (day 9): Subjects have an MRI scan during infusion through a vein of saline (salt water), followed by infusion of alcohol. For this test, a catheter (plastic tube) is placed in a vein in each arm, one for administering the saline and then alcohol; the other for drawing blood samples to measure blood alcohol level and body chemistries. Before, during and after the infusion, subjects are asked to respond to questions about their feelings, cravings and mood changes. Follow-up Subjects are asked to participate in a 3-month outpatient assessment program involving five outpatient visits (at 1, 2, 4, 8 and 12 weeks after discharge). At each visit, they fill out questionnaires and to take a breathalyzer test and blood and urine tests for drugs. They may continue naltrexone therapy and weekly group therapy sessions during this time. Subjects who do not participate in the assessment program are contacted at home by phone once a week for 1 month and then every other week for the next 2 months to monitor alcohol abstinence.
