Active clinical trials for "Substance-Related Disorders"

The purpose of this study is to evaluate the effect, pharmacokinetics and dose proportionality of buprenorphine when administered to non-dependent opiate users. 1) To evaluate whether plasma concentrations of buprenorphine increase proportionally to buprenorphine dose. 2) To evaluate the dose-response of subjective and physiological effects of buprenorphine; and 3) To determine the safety of buprenorphine.

The purpose of this 2 year study is to conduct a fully powered effectiveness trial comparing recovery trajectories of 200 drug dependent adults (the subjects) who will be randomly assigned to Treatment as Usual (TAU) or TAU + Long-Term Recovery Management (LTRM).

This is a randomized, controlled clinical trial to evaluate the effect of a computerized screening, assessment, and brief intervention on substance use in patients recruited from a primary care clinic. Study participants will be assigned to one of the following 4 study groups: computerized health screening alone (standard care) (SC); computerized assessment-only intervention (CA); computerized assessment followed by a computer-directed motivational intervention (CACI); or computerized assessment followed by a therapist-delivered motivational intervention (CATI). Data regarding substance use, medical and psychosocial functioning, and economic outcomes will be collected. The investigators hypothesize that patients randomized to CACI and CATI will be more likely to report drug abstinence at the 3-month follow-up visit and will show greater reductions in drug use at 1, 3 and 6 months follow-up than patients assigned to CA or SC. Similarly, patients in the CACI and CATI groups will report greater reductions in HIV risk behaviors, lower rates of medical and psychosocial problems, and increased economic gains at the 6-month follow-up. In addition, patients in the assessment only intervention (CA) will have outcomes superior to those found for SC patients. A cost-effectiveness analysis will also be done comparing economic costs associated with CA, CACI and CATI and their relationship to substance use reductions and related improvements in medical and psychosocial outcomes at the 6 month follow-up.

Opioid medications are commonly used for pain relief. When given over time, physical dependence can occur. This results in unpleasant side effects--such as agitation and nausea--if opioid medications are suddenly stopped. However, we do not know how withdrawal affects the brain. We know that a medication named Ondansetron can help ease or prevent symptoms associated with opioid withdrawal. Through imaging of the brain by fMRI, we hope to see how opioid withdrawal, with and without the administration of ondansetron, affects brain activity.

Context: Mothers living with HIV (MLH) and their children face predictable challenges: maintaining physical and mental health, parenting while ill, and addressing HIV-related stressors. Objective: To evaluate the efficacy of a family-based intervention over time; to contrast the life adjustments of HIV-affected families and their non-HIV-affected neighbors in the current treatment era. Design: Randomized controlled trial of MLH and a longitudinal comparison of MLH to a neighborhood cohort using random effect regression. Participants and Intervention: MLH (n = 339) and their school-age children (n = 259) were randomly assigned to receive 1) an intervention of 16 sessions in a cognitive-behavioral, small-group format; or 2) control. MLH and their children were compared to non-HIV-affected families recruited at shopping markets. Participant retention was high: 84% at 6 months, 83% at 12 months, and 78% at 18 months. Main Outcome Measures: Family functioning and conflict, mental and physical health, sexual behavior, and substance use.

This study is designed to evaluate the relative efficacy of a novel treatment (CBT-IC) versus a standard individual drug-counseling treatment. The novel treatment emphasizes exposure to emotional cues for drug use as part of a comprehensive, yet brief, treatment strategy. These treatments are delivered to opiate-dependent, often poly-substance dependent, individuals in a comprehensive methadone maintenance program who have failed to respond adequately to current treatments.

Studies demonstrate that methamphetamine (meth) use is associated with high-risk sexual behavior among MSM, putting meth-using MSM at extraordinarily high risk for transmitting or acquiring HIV. This study of intermediate size (60 participants) and length (3 months of follow-up) will assess the efficacy of mirtazapine in reducing methamphetamine use among high-risk MSM.

The aim of this study is to determine whether contingent reinforcement for smoking abstinence, compared to noncontingent reinforcement, increases the effectiveness of brief counseling and nicotine replacement on smoking abstinence of substance abusers in residential treatment.

The purpose of this study is to determine the effectiveness of a behavioral treatment, contingency management, in reducing stimulant use in persons with serious mental illness.

This study is a randomized trial of interventions to improve parent-child relationships of drug-dependent mothers.
