Filter by:The proposed protocol is a 3 group double-blind, placebo-controlled outpatient study of the safety and efficacy of Adderall-XR (ER-MAS) in the treatment of comorbid ADHD and cocaine dependence. Since this medication has independently shown promise in helping with ADHD and cocaine abuse, we are proposing that it may be successful in the treatment of comorbid ADHD and cocaine abuse. We plan to enroll 75 subjects in a 14-week trial. The primary objectives of the study are to determine the efficacy of ER-MAS in promoting cocaine abstinence and improvement in ADHD symptomology among cocaine-dependent patients with comorbid ADHD.
Stress and cues reminiscent of cocaine use promote craving and relapse in cocaine dependent individuals. In addition, there appears to be gender differences in determinants of relapse to drug use following abstinence in cocaine-dependent individuals. Therefore the purpose of the present study is to study the role of hormonal status on the response to cocaine-related cues with or without stress in cocaine-dependent women and men.
The primary objective of this study is to assess the efficacy of vigabatrin for the treatment of cocaine dependence, based on the twice-weekly qualitative urine toxicologies for cocaine. Based on two prior unblinded human studies and 15 years of animal studies, this 100 subject double- blind, randomized study is designed to show if with vigabatrin treatment but not placebo, even non-hospitalized cocaine dependent individuals with ready access to cocaine will become cocaine abstinent if they are self motivated to stop their cocaine habit. To accomplish this, cocaine dependent subjects will be randomly assigned to either a placebo or vigabatrin treatment group and treated for a nine week period. The primary hypothesis is that as compared to the placebo arm, the vigabatrin treatment arm will show a significant increase in the number of subjects who are abstinent for the final 3 weeks of the study.
Dextroamphetamine is commonly used to treat ADHD, and recent evidence suggests that this medication may decrease drug use in individuals dependent on cocaine. Thus, the present pilot study will determine the ability of dextroamphetamine to treat individuals with both cocaine dependence and ADHD.
The aim of this study is to assess the efficacy of caffeine compared to placebo as a maintenance treatment for cocaine dependence. Caffeine potentiation with biperiden will be also studied. Ninety patients with snorted/sniffed cocaine dependence will be randomized to receive caffeine (300 - 1200 mg t.i.d.) plus biperidene (8 mg b.i.d.) caffeine (300 - 1200 mg t.i.d.) with placebo or placebo during 10 days in an in-hospital setting.
The aim of this study is to assess the efficacy of caffeine compared to placebo in detoxifying cocaine dependent patients. Caffeine potentiation with biperiden will be also studied. 108 with cocaine dependence will be randomized to receive caffeine (300 - 1200 mg t.i.d.) plus biperidene (8 mg b.i.d.) or caffeine (300 - 1200 mg t.i.d.) with placebo or placebo during 6 months. Primary efficacy outcomes will be 1) patient comfort assessed with abstinence symptomatology, craving for cocaine and mental status during detoxifying period, 2) study retention and 3) cocaine use. Brain dopamine system will be assessed thru IBZM-SPECT and the apomorphine test.
The goal of this this study is to elucidate the role of the HPA axis in the pathophysiology of cocaine dependence
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 overarching goal of this project is to have a consolidated consent and evaluation procedure that will lead potential subjects to the most appropriate clinical trial or human laboratory study (and its consent process) for their presenting concerns or interests. A second purpose is to have a consolidated intake data base on which secondary analyses can be conducted.
Chronic cocaine administration leads to changes in brain function that persist long after the acute withdrawal phase. The acoustic startle response (ASR) is a well characterized reflexive response to a sudden acoustic stimulus. The ASR is mediated by a simple 3-synapse subcortical circuit; it is modulated in part by brain areas and neurotransmitters associated with cocaine administration. Our initial study and subsequent replication reveals a profound diminution of the ASR in cocaine-dependent subjects after a brief period of abstinence. Our preliminary findings indicate that first degree relatives of cocaine-dependent subjects also have reduced startle compared to healthy controls. The findings of low ASR in rats and humans during cocaine washout and low ASR in family members suggests there may be both a trait and state component of the startle reductions we have reported. The central objectives of this proposal are to dissect this finding with regard to its development and persistence in early and later phases of cocaine abstinence in humans; to ascertain whether startle reduction and its potential normalization during later abstinence is a predictor of clinical course in human subjects with cocaine dependence; and to examine whether startle reduction is, at least in part, a vulnerability trait for the development of cocaine dependence. This latter Aim will be carried out in humans by testing siblings of cocaine-dependent subjects. Cocaine dependence is an enormous public health problem. The significance of this work lies in the potential for the ASR reduction to serve as a reliable, easily repeatable biological measure of cocaine-induced brain changes that may enhance outcome prediction so that tailored treatments may be directed at those patients most vulnerable to relapse, given the restriction of resources for available for substance abuse treatment.
