85 Clinical Trials for Various Conditions
The purpose of this research is to determine if a citicoline supplement is associated with a reduction in cocaine use and craving in patients with bipolar disorder (a mental disorder marked by alternating periods of mania and depression) or schizoaffective disorder/bipolar type (a psychotic disturbance in which there is a mixture of schizophrenic and manic-depressive symptoms) and cocaine abuse/dependence. This research also wants to explore if citicoline supplements are associated with greater improvement in symptoms of mania and on memory and cognition (the mental faculty of perception, reasoning, and judgement) in these patients.
The purpose of this study is to empirically test a series of medications to: 1) determine each medication's efficacy in treatment of cocaine abuse/dependence; 2) find most effective dose range for each medication. In this study, baclofen is tested.

N-acetylcysteine (NAC) is a medication that the Food and Drug Administration (FDA) has approved for several medical uses, such as dissolving mucus in patients with breathing problems, treating overdose from acetaminophen (Tylenol), and protecting the kidneys from toxic substances. Some recent studies suggest that NAC could be useful in the treatment of other disorders including addictions. One purpose of this study is to determine whether NAC alters the level of brain glutamate (a chemical that excites brain cells). The other main purpose is to determine whether NAC affects how much cocaine people use.
This research deals with behaviors that are part of drug dependence. The purpose is to study how certain factors, including money, the amount of drug available, and the amount of work effort, affect cocaine drug choice. Specifically, we will examine the effects of two issues/factors. The first is how hard individuals are willing to work to obtain a drug; the second is how much drug would individuals choose instead of money, when the amount of probability of money is predictable or unpredictable.
The purpose of this study is to determine the safety of intravenous cocaine in subjects receiving oral donepezil.
This research study takes place at Wayne State University and will take about 11 weeks to complete. This is a treatment research study for individuals who currently have cocaine abuse or dependence, and who may also have heroin dependence. The purpose of this study is to test whether oral sustained release d-amphetamine (SR-AMP) is safe and more effective than placebo for preventing relapse to cocaine use for individuals who abuse or are dependent upon cocaine. We are also interested whether, for patients who are dependent on cocaine and heroin, whether SR-AMP is safe and effective for preventing cocaine relapse in combination with buprenorphine.
The purpose of this study is to determine whether maintenance on different oral doses of sustained release d-amphetamine (SR-AMP) combined with constant-dose sublingual buprenorphine (BUP) is safe and well tolerated and decreases self-administration of cocaine alone or combined with hydromorphone (HYD). Secondary aims are to determine whether SR-AMP attenuates the subjective and physiological effects of cocaine during drug sampling periods prior to choice opportunities.
Cocaine use disorders affect approximately 1.5 million Americans annually. Currently, there are no US Food and Drug Administration approved medications for treatment of cocaine dependence; however, both animal and human studies suggest that medications affecting the noradrenergic system can reduce cocaine craving and use. The investigators will study the effect of doxazosin, an alpha-1 adrenergic antagonist, in reducing cocaine use and anxiety symptoms among cocaine-dependent individuals. In addition, the investigators will identify genetic subpopulations of participants who preferentially respond to the medication.
This is a randomized, 4-sequence, 2-period, double-blind, placebo controlled study in male and female subjects with an American Psychiatric Association Diagnostic and Statistical Manual DSM-IV-TR diagnosis of cocaine abuse.
This study is designed to advance our development of a treatment for cocaine dependence. The investigators hypothesize that clients with high-risk characteristics will benefit from enhanced levels of treatment.
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 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.
The purpose of this study is to improve the efficacy of modafinil as a potential treatment for cocaine dependence.
The purpose of this study is to determine the safety and effects of rivastigmine and huperzine A (HupA), potential treatments for cocaine abuse, when used before experimental administration of cocaine, on a number of physical and psychological measures.
The investigators are proposing a placebo-controlled clinical trial to evaluate the efficacy and potential mechanisms of action of disulfiram (versus placebo) for treating cocaine abuse in subjects with concurrent opiate dependence and cocaine abuse or dependence maintained on buprenorphine/naloxone combination.
We are testing to see if Galantamine, a learning enhancing medication, will help methadone maintained cocaine abusers with their learning and memory specific to CBT using an innovative CBT computer program.
This study will evaluate the efficacy of ondansetron compared with placebo in the treatment of cocaine dependence.
This study examines the influence of dopamine beta-hydroxylase enzyme activity on the clinical efficacy of the novel pharmacotherapy, disulfiram, for treating cocaine dependence in cocaine-dependent patients, some of whom are opioid dependent and maintained on an FDA-approved opioid agonist. Cocaine dependence as well as co-morbid cocaine and opioid-dependence is associated with more public health issues and poorer treatment prognosis when admitted to methadone maintenance. Yet no effective pharmacotherapies have been developed to treat cocaine dependence to date. One novel pharmacotherapy, disulfiram, has shown some promise as a treatment for this disorder in several clinical trials at a dose of 250 mg/day or more (e.g., Carroll et al., 1998, 2004). This 14-week, randomized, double blind clinical trial will provide treatment for up to160 cocaine-dependent individuals, aged 18-65 years. Participants who are opioid dependent will be stabilized on methadone maintenance during the first 2 weeks and baseline cocaine use will be assessed; participants will be stratified by DBH genotype and randomly assigned to receive disulfiram at either 0, 250, 375 or 500 mg/day. During induction onto methadone for opioid dependent individuals, participants are administered increasing doses of methadone on a daily basis until maintenance doses are attained. At the beginning of week 3, participants receive methadone, if relevant, plus disulfiram or placebo disulfiram according to their randomized assignments, and are maintained on study medication(s) through week 14. At the end of the study, participants will undergo detoxification from the opioid agonist, if relevant, and active/placebo medication over a 4- to 6-week period. All participants receive weekly 1-hour psychotherapy (Cognitive Behavioral Treatment) with experienced clinicians specifically trained to deliver the therapy and who will receive ongoing supervision. Participants undergo a delay discounting session during week 1. The primary outcomes will be retention, reduction in opioid and cocaine use, as assessed by self-report and confirmed by thrice-weekly urinalyses, and disulfiram side-effects profile. Secondary outcomes will include reductions in other illicit drug and alcohol use, and improvements in psychosocial functioning. The prognostic relevance of genotype at the DBH locus, DβH activity, etc., on response to disulfiram will be examined.
Cocaine is an extremely addictive stimulant drug that directly affects the brain. It is used in several different forms and can be snorted, smoked, or injected to achieve the desired effect. Cocaine users are at risk for many health problems, both directly and indirectly related to the effects of cocaine. Disulfiram, a drug used to treat chronic alcoholism, may be effective in reducing cocaine use. This study will evaluate the effectiveness of three different doses of disulfiram in treating cocaine dependence in opioid- and cocaine-dependent individuals maintained on methadone.
Dextro-amphetamine sulfate is a central nervous system stimulant that increases the release of the neurotransmitter dopamine in the brain. The purpose of this study is to further examine dose ranges of dextro-amphetamine sulfate as a treatment for cocaine dependence.
Past research has demonstrated that cocaine dependent women experience less severe responses to cocaine during the luteal phase of the menstrual cycle, when estrogen and progesterone concentrations are high. The purpose of this study is to determine whether administered progesterone reduces subjective and physiological responses to cocaine in cocaine dependent individuals.
Cocaine dependence is a major public health problem; an effective primary treatment for cocaine dependent individuals has yet to be found. The purpose of this study is to examine the effectiveness of levodopa and carbidopa in treating cocaine dependent individuals. In addition, this study will examine the effects of incentive rewards for treatment compliance.
Cocaine dependence is a major public health problem; an effective primary treatment for cocaine dependent individuals has yet to be found. The purpose of this study is to identify subpopulations and baseline conditions that are most responsive to treatment for cocaine dependent individuals.
Although LAAM, a derivative of methadone, has been successfully used as an alternative to methadone maintenance in opioid addicts, its effect on concurrent opioid and cocaine abuse has not been ascertained. Thus, this study proposes to examine the clinical efficacy of low- and high-dose LAAM maintenance on opioid and cocaine use in opioid-dependent cocaine abusers. In addition, since contingency management procedures have demonstrated some success in decreasing cocaine use in cocaine-abusing individuals, this study also proposes to examine the clinical efficacy of the presence or absence of contingency management procedures targeting illicit drug use.
Modafinil is a medication that may enhance mood and increase energy in cocaine addicts, which may be useful in preventing cocaine relapse. Naltrexone is a medication that is currently used to treat drug and alcohol addiction. A combination of these two medications may be beneficial in reducing drug and alcohol use in individuals undergoing substance abuse treatment. The purpose of this study is to evaluate the effectiveness of modafinil and naltrexone, alone and in combination, at reducing drug and alcohol use in individuals addicted to cocaine and alcohol.
Many cocaine dependent individuals are also diagnosed with Attention Deficit Hyperactivity Disorder (ADHD). Methylphenidate (Ritalin) is currently approved to treat individuals diagnosed with ADHD. The purpose of this study is to determine the effectiveness of methylphenidate in treating ADHD symptoms in cocaine dependent individuals.
The purpose of this study is to determine the density of DA transporters during prolonged cocaine abuse and during withdrawal from cocaine use. This aim will test the hypothesis that DA transporters are altered by cocaine abuse and reestablished during withdrawal.
