Filter by:A total of 120 male and female opioid dependent cocaine users will participate in this study. This study will be a 8-week double-blind, placebo controlled study examining the dose-dependent effects of carvedilol (up to 50 mg/day) in methadone stabilized patients. The design will have two phases: 1) a four-week "treatment " phase; and 2) a 4 week " taper and detoxification or transfer" phase. Subjects will be cocaine users who are on stable doses of methadone (60 to 140 mg/day). Carvedilol dose will be increased from 12.5mg/day to the target dose of either 25 or 50 mg/day as tolerated. At the end of the treatment-phase, subjects will undergo detoxification from methadone over a 2 to 4-week period based on an individual's needs, and they will concurrently be tapered off carvedilol.
The aim of the study is to determine whether buprenorphine/naloxone maintenance versus detoxification using buprenorphine/naloxone, in prescription opioid dependent patients receiving primary care management and drug counseling in an office-based setting, leads to decreased illicit opioid use.
The major goal is to determine in patients entering buprenorphine treatment, the prevalence of specific sex-related HIV risk behaviors, their physician's screening of these behaviors and to evaluate the impact of risk reduction counseling.
A randomized clinical trial evaluating whether Behavioral Drug and HIV Risk Reduction Counseling (BDRC), abstinence-contingent take-home buprenorphine (ACB), or the combination of the two improve efficacy and cost-effectiveness of standard buprenorphine treatment for opiate-dependent individuals in Malaysia.
Prospective participants will undergo a screening process at the clinic to determine eligibility. After screening, eligible patients will complete an 8-day inpatient detoxification, followed by a 12-week outpatient phase. Patients will be randomly assigned to one of two conditions (1) Naltrexone + Placebo; (2) Naltrexone + Memantine 20 mg bid. Long-acting, injectable form of naltrexone (Vivitrol) will be administered once per month (the total of three injections) while memantine or placebo will be taken daily. In addition, patients will receive twice weekly psychosocial intervention that will include motivational interviewing and cognitive-behavioral relapse prevention. The outpatient treatment will also consist of 3 weekly visits to the clinic in which patients will receive counseling to help maintain abstinence and improve compliance with study medication.
Hepatitis C viral infection is common among opioid addicts in Zurich, Switzerland. The majority undergoes a maintenance treatment with methadone, heroin or buprenorphine. While stabilized by an opioid maintenance treatment (OMT)chronic hepatitis C can be treated with pegylated interferon plus ribavirin. As not sufficiently known, the results are comparable to the results of the treatment of nonaddicts. Our crossectional study investigates how many patients undergoing OMT are adequately investigated concerning hepatitis C. If not, why are they not adequately investigated and treated? Representative data are collected in the local clinics and medical practices involved in OMT in the Kanton of Zurich. The patients files are revised and the involved doctors are asked through a structured interview.
The purpose of this treatment research study is to assess the effectiveness of buprenorphine maintenance treatment for opioid dependence delivered in a primary care clinic setting. This study will determine whether buprenorphine treatment in primary care is effective in reducing cravings, reducing illicit opioid use, reducing addiction severity, and retaining patients in primary care treatment for opioid dependence.
This is a residential study that looks at the effects of buprenorphine in persons who abuse but are not dependent on opioids. Animal studies show that very high doses of buprenorphine produce less effects than mid-range doses. This suggests that buprenorphine can be a very safe medication. However, no studies in humans have tested higher doses in a similar way. The goal of this study is to show the effects of single doses of buprenorphine, across a range of doses, in persons who are not physically dependent on opioids (but do abuse opioids).
Buprenorphine (BPN) is an approved treatment for opioid dependence, however, in taking oral tablets, patients experience withdrawal and cravings when the variable BPN levels in the blood are low. Probuphine is an implant placed just beneath the skin that contains BPN. It is designed to provide 6 months of stable BPN blood levels. This study will test the safety and efficacy of Probuphine in the treatment of patients with opioid dependence.
The overarching goal of this project is to have a consolidated consent and evaluation procedure that will lead potential subjects to the most appropriate clinical trial or human laboratory study (and its consent process) for their presenting concerns or interests. A second purpose is to have a consolidated intake data base on which secondary analyses can be conducted.
