Active clinical trials for "Heroin Dependence"

Naltrexone is a medication that is currently used to treat drug and alcohol addiction. Guanfacine is a medication that is currently used to manage the withdrawal symptoms in individuals undergoing opioid detoxification. A combination of these two medications may be beneficial in reducing heroin use in individuals addicted to heroin. This study will evaluate the effectiveness of naltrexone and guanfacine, alone and in combination, at reducing heroin use in heroin addicts.

The purpose of this study is to assess buprenorphine/naloxone versus clonidine for inpatient opiate detoxification.

The purpose of this study is the safety and efficacy of Buprenorphine/Naloxone in the treatment of opioid dependence. A compassionate use study.

This study aims to study and implement active referral of heroin users from a syringe exchange programme to evidence-based treatment for heroin addiction. Patients are randomized to either a strength-based case management intervention or a control group, while both groups receive referral to medical investigation for inclusion in substitution treatment for heroin addiction. The hypothesis is that syringe exchange can be used for referral to effective treatment, and that a strength-based intervention can increase the number of patients who are successfully referred and enter treatment.

A randomized study is planned over 5 years to evaluate the effectiveness of the Therapeutic Workplace in promoting naltrexone ingestion and abstinence in unemployed opiate-dependent injection drug users. Participants will be offered an opioid detoxification and naltrexone induction. Participants who complete the naltrexone induction will be randomly assigned to one of two groups. Both groups will be invited to work in the Therapeutic Workplace and prescribed naltrexone for 26 weeks. The groups will differ in the contingencies imposed to work and earn salary. Work Plus Naltrexone Contingency participants will be required to ingest naltrexone to work, and will receive a brief pay decrease for missing a dose. Work Plus Naltrexone Prescription participants will be prescribed naltrexone, but will not be required to ingest it to work. This study will provide a rigorous evaluation of a novel employment-based intervention, the Therapeutic Workplace, to promote naltrexone ingestion and drug abstinence in a population of injection drug users who are at considerable risk of spreading or contracting HIV infection. Hypotheses being tested in this study are: Naltrexone ingestion will be maintained in the group exposed to the employment-based naltrexone treatment significantly more than the group exposed to usual-care treatment package. Opiate abstinence will be maintained in the group exposed to the employment-based naltrexone treatment significantly more than the group exposed to usual-care treatment package.

The purpose of this study is to evaluate the effects of treatment medications (methadone, buprenorphine, LAAM, naltrexone, naltrexone microcapsules, and methoclocinnamox) on I.V. and smoked heroin self-administration."

The purpose of this study is to assess the safety and effectiveness of buprenorphine for treatment of concurrent intravenous heroin and cocaine dependence.

The study will assess the effectiveness of at-home vs. in-office induction for patients entering buprenorphine maintenance at Associates in Internal Medicine (AIM) primary care clinic.

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.

Dependence on heroin is a major public health problem because of its association with criminality, law enforcement costs and healthcare costs. Managed withdrawal is a required first step for a long term drug-free treatment of heroin addicts. Methadone and clonidine have been the mainstay of treatment for the relief of heroin withdrawal symptoms but both have limitations. The purpose of this study was to evaluate the efficacy of buspirone in the alleviation of the withdrawal symptoms experienced by heroin addicts when they stop using heroin. Buspirone is a non opiate drug with no abuse potential, no sedating effects and no withdrawal symptoms.
