Stress is associated with drug craving and relapse in substance-dependent individuals. Hormones released from the brain may mediate the behavioral response to stress. For example, several studies have indicated that oxytocin reduces stress in laboratory stress paradigms. Specifically, it appears that oxytocin promotes trust, social interaction, and calmness; yet, little is known about the potential affects of oxytocin in cocaine-dependent individuals. Given these properties of oxytocin, it may have a therapeutic role in ameliorating the negative affect commonly observed prior to relapse in cocaine-dependent individuals, as well as the anxiety associated with withdrawal. This pilot protocol will provide important preliminary data on the effect of oxytocin on stress in cocaine-dependent individuals.
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.
We propose that the systemic administration of lidocaine following the induction of cue-induced craving, relative to saline plus cue-induced craving or lidocaine without cue-induced craving, will block the reconsolidation of cue memories. This will lead to a reduction in cue-induced craving upon repeated testing as well as subsequent cocaine use and basal craving.
Cocaine-use disorders continue to be a significant public health concern, yet no effective medications have been identified. The goal of this study is to establish a research platform for the development of medications for treatment of cocaine abuse and dependence. This study will incorporate self-administration procedures and a non-drug alternative reinforcer, which is hypothesized to reduce the reinforcing effects of cocaine.
The primary objective of this study is to assess the efficacy and safety of TV-1380 [Recombinant human serum albumin (HSA) mutated butyrylcholinesterase (AlbuBChE)] in facilitating abstinence in cocaine-dependent subjects.
The purpose of this study is to evaluate if exercise added to usual treatment improves cocaine dependence treatment. The primary objective of this study is to investigate if exercise can facilitate cocaine craving reduction. The secondary aims are to evaluate if exercise can reduce negative mood states, improve quality of life and facilitate abstinence of cocaine.
The investigators' recently completed study has provided the first evidence that administration of the medication propranolol, following exposure to cocaine cues, can alter drug-associated memories and reduce craving and other drug cue-elicited responses in cocaine addicted persons. The investigators will attempt to augment this effect by a) doubling the number of propranolol-medicated cocaine cue exposure (CCE) retrieval sessions and b) increasing the dose of propranolol. It is expected that propranolol treated groups, relative to placebo treated groups, will evidence greater reduction of craving, cue reactivity and cocaine use during follow-up cocaine cue exposures. Also, these effects will be greater for those who receive 80mg of propranolol as opposed to 40mg.
Crack addiction has become a severe health problem in Brazil. Today, crack addiction is the primary cause for inpatient treatment for all illicit substances. When compared to cocaine, crack users develop much faster diagnoses for crack dependence, shows a more compulsive pattern of use, has higher probability of living or have lived in the streets, and of engaging in illegal activities. Consequently to this, mortality of crack addicts is 7 times higher than for the rest of the population. Despite all efforts being made for the development of effective pharmacological treatments for stimulant addiction (crack included), up to today, there is no robust evidence of efficacy of any pharmacological treatment. For that reason, the use of evidence based psychosocial interventions is so important for treating this population. Although today open treatment facilities in Brazil are more and more starting to use evidence-based interventions such as motivational interviewing, cognitive behavior therapy, relapse prevention and coping skills, such treatments present very modest results when treating crack addiction. The biggest difficulties encountered when treating this population are maintaining patients in treatment, reducing crack use and achieving continued abstinence. A psychosocial treatment based in behavioral principals' named Contingency Management (CM) is widely applied in the USA. Recent meta-analyses and review studies present robust evidence that, when applied alone or in adjunction with other psychosocial and pharmacological treatment, CM is the most effective treatment for what regards, treatment retention, reducing drug use and promoting continued abstinence. The purpose of this study is to evaluate if Contingence Management (CM) can be affective in the treatment of crack addiction in Brazil. To accomplish this, 60 individuals (male and female from 18 to 65 years of age) seeking open treatment for crack addiction will be randomized to 2 treatment conditions (Standard treatment (ST) or ST+CM. Both treatments will last 12 weeks with 3 and 6-month follow-up. In both groups patients will be encourage to leave urine samples 3 times week. Hypotheses: Patients receiving ST+CM will stay longer in treatment, have more negative tests for cocaine/crack, and achieve longer periods of cocaine/crack abstinence when compared to patients receiving ST alone.
The proposed protocol is a multi-site double-blind, placebo-controlled outpatient study of the safety and efficacy of Adderall-XR (MAS-ER) and topiramate in the treatment of cocaine dependence. 198 patients will be enrolled and 176 patients randomized in a 14-week trial. The proportion of participants achieving sustained cocaine abstinence for three consecutive weeks at the end of the study will be significantly greater for the combined pharmacotherapies group compared to the placebo group.
