A double-blind placebo-controlled crossover Phase I trial was conducted to assess the safety and tolerability of N-Acetylcysteine (NAC) in healthy, cocaine-dependent humans. Thirteen participants attended a three-day hospitalization in which they received placebo or NAC. Subjects were crossed over to receive the opposite medication condition during a second(More)
The cold pressor test (CPT) and Trier Social Stress Test (TSST) have been shown to reliably increase HPA activity; however, little research has compared responses to these stressors. In this study, biological (plasma cortisol and ACTH levels) and subjective (e.g., stress and mood) responses were compared in 31 subjects administered both the CPT and TSST.(More)
UNLABELLED There are likely to be gender differences in determinants of relapse to drug use following abstinence in cocaine-dependent individuals. Cocaine-dependent women are more likely to attribute relapse to negative emotional states and interpersonal conflict. Cocaine dependence has also been linked to dysregulation of stress response and the(More)
OBJECTIVE Animal models suggest that N-acetylcysteine inhibits cocaine-seeking. The present pilot study evaluated whether N-acetylcysteine would suppress reactivity to cocaine-related cues in cocaine-dependent humans. METHOD In this double-blind, placebo-controlled trial, 15 participants received N-acetylcysteine or placebo during a 3-day hospitalization.(More)
BACKGROUND The association between stress and alcohol dependence has been well established. Abnormalities in stress reactivity and hypothalamic-pituitary-adrenal axis (HPA) function may be involved in the mechanistic connection between stress and the initiation, development, and/or maintenance of alcohol dependence. Posttraumatic stress disorder (PTSD)(More)
CONTEXT Corticotropin-releasing hormone (CRH), through the hypothalamic pituitary adrenal axis and other brain stress systems, is involved in the emotional dysregulation associated with cocaine dependence. Little is known about the response of cocaine-dependent individuals to CRH administration. OBJECTIVE The primary objective was to examine the(More)
Posttraumatic stress disorder (PTSD) is a prevalent condition that has been shown to be responsive to pharmacotherapy. Few head-to-head comparisons of medications used in the treatment of PTSD have been published. This 12-week, randomized, double-blind study compares the effectiveness, safety, and tolerability of nefazodone and sertraline for the treatment(More)
Substance abuse and dependence is a public health problem with far-reaching societal implications. The acute toxicity of substances of abuse and medical consequences of chronic use are substantial. On a more optimistic note, a great deal of progress has been made in understanding and treating substance use disorders. Expanding knowledge concerning the(More)
This study highlights respondent sensitivity to daily hassles as it relates to situational cocaine use and perceived long-term effects of adverse events in childhood. Data were drawn from a larger study on stress reactivity in cocaine dependent individuals. Participants (n=104) were cocaine dependent men and women without comorbid posttraumatic stress(More)
Until recently, relatively little research has focused on the treatment of marijuana abuse or dependence; however, marijuana use disorders are now receiving increased attention. This paper reviews the initial clinical trials evaluating the efficacy of outpatient treatments for adult marijuana dependence. Findings from five controlled trials of(More)
