Filter by:The problem of cocaine dependence remains a major medical, social, and legal concern. Several studies have suggested that disulfiram may be beneficial for the treatment of cocaine dependence. A common assumption has been that disulfiram treatment, by increasing DA availability, enhances the aversive aspects of stimulants. This study aims to measure plasma activity in those with the C/C DBH genotype, which is associated with higher DBH activity subsequently making the disulfiram treatment more effective, as well as determine the effects of treatment with disulfiram on cocaine self-administration using a human laboratory model of cocaine self-administration.
-Context: Study objectives Primary: impact of modafinil versus placebo on DAT density modifications in the striatal and extra-striatal regions in cocaine dependent subjects hospitalised from D3 to D21. Primary Hypothesis: More rapid normalisation of DAT concentrations measured by PET using modafinil versus placebo from D3 to D21 during cocaine detoxification.
This placebo-controlled trial will test the effectiveness of Seroquel XR™ for the treatment of cocaine dependence in non-psychotic individuals who are cocaine dependent.
This is a Phase 1 safety/tolerably study to determine if there are clinically significant interactions between oral vigabatrin (gamma vinyl-gamma-amino butyric acid; VGB) concurrent with intravenous (IV) cocaine infusions.
The purpose of our research is to examine the promise of a new computer based approach to use in usual drug counseling when treating crack cocaine addiction.
Subjects will be randomly assigned to receive either one of the two potential dose combinations of the study medications or placebo over 6 weeks. The study will include twice weekly visits to the research clinic for laboratory studies, safety assessments and urine drug screens. Subjects will also be questioned regarding drug craving and mood symptoms.
Background: - The treatment of addiction often hinges on preventing relapse into drug-using behaviors, which occurs at high rates even after prolonged abstinence. Research has shown that constant reporting through personal data-collection devices, such as electronic diaries, can help prevent relapse and reinforce abstinence. This constant reporting is known as Ecological Momentary Assessment (EMA). - The researchers here at NIDA have already completed two major arms of the study, focusing on patterns of craving and drug use during methadone maintenance, and on whether electronic diaries could help remind outpatients to complete treatment tasks. An ongoing arm of the study is examining connections among drug craving/use, stress, and geographical location. Objective: - To investigate the role of stress associated with geographical location in drug craving and use. Eligibility: - Individuals between 18 and 65 years of age or older who are dependent on opioids (cocaine and/or heroin). Design: - The study will last 28 weeks. After the initial screening, participants will receive daily methadone and weekly drug counseling sessions that will continue throughout the study. - After 3 weeks of methadone treatment, participants will have 15 weeks of EMA in which they will record both event-triggered cravings and daily responses (3 per day). EMA will consist of event-triggered recordings (initiated by participants whenever they use heroin or cocaine, or whenever they feel an urge to do so) and random-signal-triggered recordings (3 per day). During EMA, participants will begin a voucher-based program to encourage abstinence from heroin and cocaine. - Participants will also carry global positioning system (GPS) units to record their locations during these 15 weeks, and will complete questionnaires about stress levels at specific intervals during the study. - At the end of the study, participants will have the choice of transferring to a community clinic or undergoing an 8-week taper from methadone.
