Active clinical trials for "Cocaine-Related Disorders"

The purpose of this study is to evaluate the effects of Topiramate and Cognitive Behavioral Therapy for the treatment of alcohol and cocaine dependence.

The purpose of this study is to assess the safety of intravenous (IV) cocaine in subjects taking quetiapine at 3 dosage levels.

The purpose of this study is to evaluate clinical safety issues pertaining to lisuride, to cocaine, and to its interaction in a chronic, crack dependent population, and to determine how pretreatment with lisuride modifies the subjective as well as physiological effects of cocaine.

Transcranial direct current stimulation (tDCS) is a form of non-invasive brain stimulation in which low level electrical currents are applied to the scalp in order to alter brain function. In a prior Phase-I study, the research team demonstrated feasibility of self-administration of a home-tDCS prototype in 14 patients that applied 15 sessions for each patient at an outpatient center.

The primary objective is to investigate the potential ability of Inderal (propranolol hydrochloride) to diminish the reconsolidation of motivationally potent drug-related cues in cocaine dependent participants. If effective in this laboratory model, Inderal may have clinical efficacy.

Although a great amount of research has been conducted to resolve cocaine dependence, an effective treatment has yet to be discovered. Topiramate is a drug that was found to be useful in treating alcohol dependence. The purpose of this study is to determine the effectiveness of topiramate in treating cocaine dependent individuals.

The purpose of this study is to assess GBR 12909 in cocaine experienced African American Volunteers.

The purpose of this study is to evaluate safety issues pertaining to dihydrexidine (DHX), to cocaine, and to its interaction, and to determine how pretreatment with DHX modifies the subjective as well as physiological effects of cocaine infusion.

Background: Cocaine use disorders (CUD) is a complex brain disorder, involving several brain areas and neurocircuits. Effective treatments for CUD are still needed. Repetitive transcranial magnetic stimulation (rTMS) stimulates non-invasively parts of the brain. Preliminary data suggest that rTMS may help reducing cocaine craving and consumption. Researchers want to learn how the brain and the drug-seeking behavior may change with this treatment. Objectives: To test if rTMS can reduce cocaine craving and use, and also affect several mood, behavioral and cognitive alterations associated with prolonged cocaine use. Eligibility: Healthy, right-handed adults ages 18-65 who do have cocaine use disorder (moderate to severe). Design: This is a randomized, double-blind, sham-controlled study. The study includes three phases: 1) a rTMS continued treatment phase; a rTMS follow-up; and a no rTMS follow-up. Prior to participating, participants will be screened with: Questionnaires Medical history Physical exam Urine tests MRI (structural) After being enrolled, baseline behavioral and imaging data will be collected. In particular, participants will undergo: Questionnaires Functional MRI During the continued rTMS phase, participants with cocaine use disorder will be randomized to receive real or fake rTMS. Repetitive TMS will be delivered during 10 outpatient treatment days, over 2 weeks (5 days/week). Following this phase, subjects will have 12 follow-up visits (once/weekly), during which they will receive rTMS, and behavioral and imaging assessments will be performed. At the end of the rTMS follow up period, participants will further receive 3 follow up visits (once a month), during which rTMS will not be performed, but behavioral data will be collected. Treatment includes: rTMS: A coil is placed on the head. A brief electrical current passes through the coil. At each visit, participants will receive two rTMS sessions, with a 1hr interval between sessions. At the beginning of each rTMS session, they view cocaine-related images for few minutes. MRIs at baseline and at follow-up visit #12: Participants lie on a table that slides into a cylinder that takes pictures of the brain. They respond to images while in the scanner.

This study evaluates the use of N-acetylcysteine in the treatment of alcohol and cocaine use disorders. Alcohol users will be split in two groups, one will receive the active N-acetylcysteine and the other placebo. The same division will occur with cocaine users. The effects of N-acetylcysteine in adherence, abstinence, psychiatric symptoms and stress biomarkers will be evaluated.
