Filter by:Cocaine dependence involves problematic neuroadaptations, such as heightened reactivity to cocaine cues, that may be responsive to pharmacological modulation of glutamatergic circuits. Despite promising preclinical findings with n-methyl-d-aspartate receptor (NMDAr) modulators, studies with human subjects have been unsuccessful to date. The purpose of this investigation is to examine the effects of the NMDAr antagonist ketamine, recently found to have potent therapeutic effects in humans, on cue-induced craving and impaired motivation for quitting cocaine in cocaine dependent participants, 24-hours post-infusion.
Modafinil has been reported to reduce cocaine use in a clinical sample of infrequent users (2 days/week), but the effects of modafinil on cocaine self-administration in the laboratory have not been studied. The present study investigated the effects of modafinil maintenance on cocaine self-administration by frequent users (4 days/week) under controlled laboratory conditions. During this 48-day double-blind, crossover design study, the effects of modafinil maintenance (0, 200, and 400mg/day) on response to smoked cocaine (0, 12, 25, and 50 mg) were examined in nontreatment seeking cocaine-dependent individuals (n = 8).
More Americans are arrested for drug offenses than for any other crime. In 2009, over 294,000 arrests were made for possession of cocaine or heroin. Incarceration does not address the root problems and is frequently followed by relapse and re-arrest after release. In the case of opiate-dependent adults arrested for possession of heroin, one potentially effective alternative is to divert offenders to methadone maintenance treatment (MMT) as an alternative to adjudication of their case. MMT is an effective treatment for heroin dependence, and appears very effective for criminal offenders. However, cocaine use is common in MMT patients, including those with recent criminal justice involvement, and MMT alone is ineffective in addressing cocaine use. Continued cocaine use carries a substantial health burden and necessarily entails continued criminal activity. Thus, treatment for diverted opiate-dependent offenders should be designed to address cocaine use as well as opiate use. A Stage 1 Behavior Therapy Development project is planned over 2 years to adapt, manualize and pilot test the Therapeutic Workplace intervention for adults charged with heroin possession and offered diversion to methadone maintenance treatment as an alternative to adjudication of their case. The Therapeutic Workplace is a novel, employment-based contingency management intervention that has been very effective in promoting cocaine abstinence in adults who use cocaine persistently during methadone treatment. In the Therapeutic Workplace, participants are hired in a model workplace and required to provide drug-free urine samples to work and to earn maximum pay. Once we develop and manualize the adapted version of the Therapeutic Workplace for adults arrested for heroin possession, a pilot test will be conducted. Individuals identified by the State Attorney's office as candidates for diversion will be assessed for study eligibility. Given the high rates of injection drug use and injection-related transmission of HIV in Baltimore, this study will be restricted to injection drug users to evaluate the potential utility of this intervention in reducing HIV risk. Eligible individuals will be offered methadone maintenance in lieu of prosecution and will be required to remain in methadone treatment for 90 days. All participants will receive standard MMT, independent of whether they decide to participate in the pilot study. After beginning MMT, participants will be invited to enroll in the pilot study and randomly assigned to two study groups. Participants assigned to the Usual Care Diversion group will receive the standard MMT. Participants assigned to the Therapeutic Workplace Enhanced Diversion group will receive the standard MMT and the Therapeutic Workplace intervention. The data from this pilot study will serve as the foundation for a full-scaled randomized controlled trial. Overall, the Therapeutic Workplace could serve as a novel and ideal intervention for many heroin dependent adults involved in the criminal justice system. The use of MMT in lieu of adjudication in combination with the Therapeutic Workplace could increase drug abstinence and employment and decrease HIV risk and criminal activity in this refractory high-risk population.
The objective of this study is to evaluate the safety and efficacy of Nepicastat in improving the number of subjects that achieve abstinence from cocaine and reducing cocaine use in subjects with cocaine dependence.
This is a double-blind placebo-controlled clinical trial (n = 156) of varenicline for the treatment of cocaine dependence that utilizes contingency management to promote treatment attendance.
In the proposed study, the investigators will assess the brain response to medication probes the investigators have previously studied with SPECT. The brain response to ondansetron and lidocaine infusions will be measured Arterial Spin Labeling and functional connectivity MRI (fcMRI).
The purposes of this study are as follows: 1. To assess the cardiovascular and subjective effects of cocaine during treatment with pramipexole and placebo. 2. To assess the reinforcing effects of cocaine, measured using choice procedures, during treatment with pramipexole and placebo.
The purpose of this study is to determine the effects of treatment with cabergoline, compared to treatment with placebo, on cocaine induced craving and subjective effects in cocaine-dependent human volunteers.
The purpose of this study is to evaluate whether or not buspirone is effective in preventing relapse in cocaine-dependent adults in inpatient/residential treatment who are planning to enter outpatient treatment upon inpatient/residential discharge.
The purpose of this study is to test the effects of exercise on cocaine use, fitness, and cravings for cocaine and nicotine. This study is part of an effort to develop treatments for cocaine abuse.
