Background: - Relapse to drug abuse is thought to result, in many cases, from exposure to cues that trigger drug-related memories or emotional associations for example, the association between the sight of a crack pipe and a set of responses such as rapid heartbeat and desire for cocaine. This type of memory is reconsolidated (actively re-stored) each time it is reactivated; however, the reconsolidation process can be disrupted by the drug propranolol, which weakens the link between that memory and an emotional response. - Propranolol is traditionally used to treat high blood pressure and other heart-related conditions. Researchers are interested in studying whether propranolol disrupts reconsolidation of drug-cued memories in individuals who are addicted to cocaine. Objectives: - To examine whether propranolol can interfere with reconsolidation of cocaine-related memories and reduce cravings and drug use in substance abusers. Eligibility: - Individuals between 18 and 55 years of age who are current cocaine users enrolled in a methadone treatment program. Design: - The study will involve four long sessions (visits 1, 4, 6, and 14) and 10 short sessions. The short visits will be for monitoring of participants use of drugs and alcohol; the longer visits will involve more tests and lab sessions. Participants will be randomized to either the propranolol or placebo group. - The long sessions will involve the following procedures: - An interview session to develop a personalized drug script/cue set. - A two-hour intervention session with baseline measures, drug administration (propranolol or placebo), and two script-guided imagery sets. This is the only administration of propranolol during the study. - Two follow-up test sessions, 1 and 5 weeks after the intervention session. - Participants will make brief visits to our outpatient clinic for twice-weekly monitoring of ongoing drug use via urine screens and self-report, starting 1 week before the intervention session and ending 5 weeks later.
This study tests the effectiveness of two 24 month, telephone-based adaptive continuing care interventions for patients with cocaine dependence. The two interventions are predicted to produce better drug use outcomes than standard care. Furthermore, the intervention that also includes monetary incentives for continued participation is hypothesized to produce better retention and drug use outcomes than the intervention without incentives. Economic analyses will determine the cost-effectiveness and benefit-cost of the interventions relative to standard care, and to each other.
This is an outpatient clinical trial of topiramate for addressing cocaine dependence and reduction of cocaine associated behaviors in opiate dependent drug users maintained on methadone treatment. The study aims to answer whether topiramate 1. is safe and acceptable to methadone patients 2. reduces cocaine use 3. helps with collateral problems such as alcohol abuse, tobacco dependence, anxiety, PTSD and/or pain symptoms. The study will also evaluate topiramate effect on neuro-cognitive performance.
This study will assess the potential interaction and subjective effects between intravenous cocaine and SYN117 in non-treatment seeking cocaine dependant subjects
To examine the clinical efficacy of sertraline (200 mg/day) alone or sertraline in combination with gabapentin. The purpose of this study is to examine whether the antidepressant sertraline alone or combined with gabapentin delays time to relapse relative to placebo in recently abstinent cocaine-dependent volunteers who are also depressed. In addition, whether depressive symptoms or genetic factors influence treatment response to the study medications will be examined. Our hypothesis is that those on combined sertraline-gabapentin will show a longer period of abstinence than those on sertraline alone or placebo.
The purpose of this pilot treatment trial is to evaluate the efficacy of oral micronized PROG in cocaine-dependent women. Since we have shown (Evans & Foltin, 2006) that oral micronized PROG attenuates the positive subjective effects of smoked cocaine in females, but not in males, and we have preliminary data indicating that oral micronized PROG also reduces smoked cocaine self-administration in the laboratory, PROG appears to be an ideal potential candidate medication to evaluate in cocaine-dependent women. Prior to randomization to treatment, women will reside inpatient for one week to ensure cocaine abstinence since one of the primary outcome measures will be time to cocaine relapse.
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.
A 12-week, randomized, double-blind, parallel-group, placebo-controlled trial of citicoline as an add-on therapy will be conducted in 200 outpatients with bipolar I disorder and cocaine dependence. Patients will complete mood and memory assessments weekly, in addition to completing self-report measures for cocaine (and other substances, like alcohol) use and craving. Participants will receive manual-driven Cognitive Behavioral Therapy (CBT: two sessions each week for 4 weeks followed by weekly sessions, total 16 sessions) specifically designed for persons with bipolar 1 disorder and substance abuse, and provided by a therapist with experience in CBT. The sessions may be videotaped for training purposes and may be viewed by the researchers, the therapist, and Dr. Schmitz, a clinical researcher at the University of Texas Houston who is the developer of the CBT for bipolar disorder and substance dependence used in the study. Before being videotaped, the patient will sign an "Authorization for Audio Recordings, Photography, or Other Images for Non-Treatment Purposes" to further understand how the videotape will be used, and by whom. The patient will be given the option to review their videotape to view their therapy session. Once the patient has completed all study procedures, or had discontinued the study, the tape will be destroyed, until then the tape will kept in the patient's confidential study file. Further, patients will return to the clinic three times a week for urine drug tests (UDS). 200 patients are expected to be consented for this study and all study procedures will take place at the clinic on the University of Texas Southwestern Medical Center campus. All non-study medications are not part of the study. Non-study medication will be verbally self-reported by the patient at the time of enrollment into the study. The patient will be responsible for the costs of their non-study related medications. The patient will manage their non-study medications with their personal doctor, including any changes in these medications. However the protocol has concomitant medication algorithm in the event that a change in the medication schedule needs to be made by a study doctor. If a study doctor requests a laboratory test for the patient, it will be paid for by the clinic. Otherwise, the patient will be responsible for all costs (including laboratories) associated with their non-study medications.
The objective of this study is to demonstrate that a larger proportion of vigabatrin-treated subjects than placebo-treated subjects will be cocaine-free in the last 2 weeks of treatment.
