Efficacy Evaluation of Traditional Chinese Medicine JITAI Combined Comprehensive Model Among Heroin...
Heroin AddictionThe purpose of this research is to observe the efficacy of comprehensive treatment model to improve treatment compliance and relapse prevention.
Buprenorphine/Naloxone Treatment for Opioid Dependence-Experiment III) - 3
Heroin DependenceOpioid-Related DisordersThe purpose of this study is to compare the clinical efficacy of the buprenorphine/naloxone combination tablet to methadone for opioid maintenance treatment.
Buprenorphine/Naloxone Treatment for Opioid Dependence-Experiment II-1 - 4
Heroin DependenceOpioid-Related DisordersThe purpose of this study is to assess the abuse liability and examine the reinforcing effects of intravenous buprenorphine and buprenorphine/naloxone combinations in buprenorphine-naloxone maintained volunteers
Buprenorphine/Naloxone Treatment for Opioid Dependence-Experiment II-2 - 5
Heroin DependenceOpioid-Related DisordersThe purpose of this study is to assess the abuse liability and reinforcing effects of intravenous buprenorphine and buprenorphine/naloxone combinations in heroin-dependent volunteers
Change the Cycle: An RCT to Prevent Injection Initiation
Substance AbuseIntravenous5 moreThe study will test the efficacy of a hour long, one-on-one, active listening counseling session (called Change the Cycle or CTC) aimed at reducing behaviors among active people who inject drugs (PWID) that research has found to facilitate uptake of injection drug use among non-injectors. The study will involve ~1,100 PWID who will be randomized to CTC or an equal attention control intervention on improving nutrition. Participants will be recruited in Los Angeles and San Francisco, California and followed up at 6 and 12 months to determine changes in direct and indirect facilitation of injection initiation among non-injectors.
Buprenorphine/Naloxone Treatment for Opioid Dependence-Experiment 1 - 1
Heroin DependenceOpioid-Related DisordersThe purpose of this study is to assess the clinical efficacy of the buprenorphine/naloxone combination tablet for alternate-day dosing and determine whether multiples of the daily dose are necessary to maintain an effective alternate day dosing regimen.
Reinforcing Effects of Intranasal (IN) Buprenorphine Versus Buprenorphine/Naloxone
Heroin DependenceThe study is designed to compare the abuse liabilities of intranasal buprenorphine and buprenorphine/naloxone in individuals who are physically dependent on sublingual buprenorphine. The investigators hypothesize that the abuse liability of buprenorphine/naloxone is lower than that of buprenorphine alone.
Depot Naltrexone Mechanism of Action in Heroin Dependent Patients Using fMRI and SPECT
Opioid-Related DisordersHeroin DependenceThe aim of this project is to study brain functions of 20 heroin addicts (compared to brain functions of 20 healthy controls) just before and during a three month extended release naltrexone treatment using functional MRI and dopamine transporter SPECT. The following hypotheses are tested: XRNT modulates the fMRI response to drug cues in predetermined brain regions. The expression of striatal transporters (assessed with SPECT) will decrease after a three-month course of extended release naltrexone
Effect of Stress on Heroin-Related Memory Retrieval
Heroin DependenceLearning and MemoryThe purpose of this study is to determine whether cortisol and propranolol are effective in the modulation of stress induced heroin-related retrieval enhancement.
Effects of Buprenorphine/Naloxone Dose on Experimental Stress Reactivity and Opioid Abstinence
Heroin DependenceOpioid Use DisorderThis research deals with behaviors that are part of opioid dependence. The purpose is to study how stress and medication dose can affect opioid drug use.
