BACKGROUND Erectile dysfunction (ED) is common among men on opioid replacement therapy (ORT), but most previous studies exploring its prevalence and determinants yielded contrasting findings. Moreover, the impact of ED on patients' quality of life (QoL) has been seldom explored. OBJECTIVE To explore the prevalence and determinants of ED in men on ORT, and the impact on QoL. METHODS In a mul...

BACKGROUND Cohort studies provide an excellent opportunity to monitor changes in behaviour and disease transmission over time. In Australia, cohort studies of people who inject drugs (PWID) have generally focused on older, in-treatment injectors, with only limited outcome measure data collected. In this study we specifically sought to recruit a sample of younger, largely out-of-treatment PWID, ...

The recent approval of office-based treatment for opioid addiction and US Food and Drug Administration approval of buprenorphine will expand treatment options for opioid addiction. Buprenorphine is classified as a partial micro opioid agonist and a weak kappa antagonist. It has a high affinity for the micro receptor, with slow dissociation resulting in a long duration of action and an analgesic...

BACKGROUND In recent years, an abstinence-focused, 'recovery' agenda has emerged in UK drug policy, largely in response to the perception that many opioid users had been 'parked indefinitely' on opioid substitution therapy (OST). The introduction of ten pilot 'Drug Recovery Wings' (DRWs) in 2011 represents the application of this recovery agenda to prisons. This paper describes the DRWs' operat...

BACKGROUND Opioid substitution treatment (OST) has multiple benefits for heroin injectors and is an evidence-based major component of international treatment. The current qualitative study sought to explore participants' attitudes to and reasons for participating in a feasibility randomised trial in primary care offering 'same day' OST (methadone) for injecting heroin users compared to usual ca...

BACKGROUND In eastern Europe, the high prevalence rates of HIV and the hepatitis C virus (HCV) are concentrated among injecting drug users (IDUs). Harm reduction programmes such as needle and syringe programmes and opioid substitution therapy (OST) have been shown to be effective in preventing these infections. However, structural barriers can limit their effectiveness by hindering access. ME...

BACKGROUND AND OBJECTIVES Promoted globally as an evidence-based intervention in the prevention of HIV and treatment of heroin addiction among people who inject drugs (PWID), opioid substitution treatment (OST) can help control emerging HIV epidemics among PWID. With implementation in December 2014, Kenya is the third Sub-Saharan African country to have introduced OST. We combine dynamic mathem...

BACKGROUND Hepatitis C virus infection is highly prevalent among people who inject drugs. Opioid substitution therapy, the standard treatment for opioid dependence, provides an excellent opportunity for the treatment of hepatitis C virus infection due to the close and regular contact between patients and clinicians. However, there is little research on the impact of opioid substitution therapy ...

Objectives: This study presents the comparative safety and side effect profiles of buprenorphine and methadone, including gender relationships, from a clinical trial comparing buprenorphine and methadone in the outpatient treatment of opioid dependence. Methods: One hundred sixty-four opioid dependent volunteers age 18–50 years were randomized to buprenorphine (n = 84) or to methadone (n = 80) ...

Methadone is widely being used for opioid substitution therapy. However, the administration of methadone to opioid dependent individual is frequently accompanied by withdrawal syndrome and chemical dependency develops. Other than that, it is also difficult to retain patients in the treatment programme making their retention rates are decreasing over time. This article is written to higlights th...
