Since January 1994, heroin-assisted treatment for opiate addicts has been available in Switzerland. This is the first report of the long-term effects of this form of treatment. The report examines subjects who entered a study involving medical prescription of opiates (Projekt zur ärztlichen Verschreibung von Betäubungsmitteln; PROVE) in Switzerland between January 1994 and March 1995 (n = 366)....

INTRODUCTION Spain is one of the few countries to have widely implemented opioid substitution treatments (OST) and needle exchange programmes (NEP) for drug users in prison. We analyze the evolution of the need, coverage and the timeliness of these interventions in Spain between 1992 and 2009. METHODS Data on the provision of interventions is taken from official publications. The need was cal...

The HIV transmission component of a previously published HIV and HCV transmission model[1] was adapted and used in this analysis, and is described in appendix 2. The model is divided into two intervention sub-groups:no opioid substitution therapy (OST) and OST. The IDUs in the OST group are assumed to have a reduced HIV transmission risk. Initially, the model assumes that no one is in these int...

There has been recent concern about the association between high dose methadone and prolongation of QTc in the electrocardiogram. QTc is the time from the beginning of the QRS complex to the end of the T have as measured on an electrocardiogram and corrected for heart rate. To date, no association has been made between methadone and buprenorphine in commonly used doses and prolonged QTc. Electr...

AIMS Methadone and buprenorphine diversion by patients in opioid substitution treatment (OST) is a poorly understood phenomenon. We study the norms and attitudes on diversion among OST patients, including the role these norms and attitudes play as diversion risk factors. We also study whether perceived quality of care, social bonds to treatment staff, and deterrence can be associated with diver...

Nineteen heroin-dependent male volunteers were administered buprenorphine sublingually, in ascending daily doses of 2, 4, and 8 mg. They were maintained on 8 mg daily through study day 18. On study days 19 through 36, subjects in group 1 continued to receive burprenorphine daily; subjects in group 2 received buprenorphine or placebo on alternate days. On days 37 through 52, all subjects receive...

BACKGROUND Opioid substitution therapy (OST) is the most commonly provided treatment for heroin dependence in Australia and has been shown to be effective. Access to OST outside of specialised public clinics and prisons relies on the participation of general practitioners. In Australia there is a shortage of GPs available to prescribe OST, which results in an unmet need for OST services. Studie...

Interim medication-only treatment has been suggested for the initiation of opioid maintenance treatment (OMT) in opioid-dependent subjects, but this rarely has been studied using buprenorphine instead of methadone. Following a pilot trial assessing interim buprenorphine-naloxone treatment in order to facilitate transfer into OMT, we here aimed to study retention, and potential correlates of ret...

BACKGROUND Opioid use disorders are considered a serious public health problem among young adults. Current treatment is limited to long-term opioid substitution therapy, with high relapse rates after discontinuation. This study evaluated the co-administration of memantine to brief buprenorphine pharmacotherapy as a treatment alternative. METHODS 13-week double-blind placebo-controlled trial e...

BACKGROUND/AIM Relapse of opiate dependence is a common occurrence after detoxification and introduction of opiate addicts in abstinence from opiates. Clinical evaluation showed that over 90% of opiate addicts exhibit depressive manifestations during detoxification, or develop post-detoxification depression. The aim of this study was to determine differences in the frequency of relapses, severi...
