Rodger L, Nader M, Turner S, Lurie E. Initiation and rapid titration of methadone and slow-release oral morphine (SROM) in an acute care, inpatient setting: a case series. Eur J Med Res 2023; 28:573. [PMID: 38066517 PMCID: PMC10704823 DOI: 10.1186/s40001-023-01538-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2022] [Accepted: 09/02/2022] [Indexed: 12/18/2023] Open
Abstract
BACKGROUND Methadone titration in an outpatient setting typically involves initiation with subtherapeutic doses with slow titration to mitigate the risks of respiratory depression and overdose. In pregnancy, and generally, subtherapeutic doses of methadone and slow titrations are associated with poorer outcomes in terms of treatment retention and ongoing illicit opioid use. We aim to describe rapid titration of OAT in an inpatient setting for pregnant injection opioid users with high opioid tolerance secondary to a fentanyl-based illicit drug supply. METHODS Retrospective case series of patients admitted to a tertiary center with a primary indication of opioid withdrawal and treatment for severe opioid use disorder in pregnancy. RESULTS Twelve women received rapid methadone titrations with or without slow-release oral morphine for opioid use disorder during a total of fifteen hospital admissions. All women included in the study were active fentanyl users (12/12). Methadone dosing was increased rapidly with no adverse events with a median dose at day 7 of 65 mg (IQR 60-70 mg) and median discharge dose of 85 mg (IQR 70-92.5 mg) during their admission for titration. Slow-release oral morphine was used in half of the titration admissions (8/15) with a median dose of 340 mg (IQR 187.5-425 mg) at discharge. The median length of admission was 12 days (IQR 9.5-15). CONCLUSIONS A rapid titration of methadone was completed in an inpatient setting with or without slow-release oral morphine, without adverse events showing feasibility of this protocol for a pregnant population in an inpatient setting. Patients achieved therapeutic doses of methadone (and/or SROM) faster than outpatient counterparts with no known adverse events.

Discontinuation of opioid agonist treatment following release from prison in a cohort of men who injected drugs prior to imprisonment in Victoria, Australia: A discrete-time survival analysis. Drug Alcohol Depend 2023; 242:109730. [PMID: 36516552 DOI: 10.1016/j.drugalcdep.2022.109730] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/26/2022] [Revised: 11/26/2022] [Accepted: 12/06/2022] [Indexed: 12/12/2022]
Abstract
BACKGROUND Retention in opioid agonist treatment (OAT) following release from prison is associated with improved outcomes, however factors associated with post-release OAT discontinuation in Australia are poorly understood. We examined post-release OAT discontinuation in a cohort of men who engaged in approximately monthly injecting drug use (IDU) prior to imprisonment in Victoria, Australia. METHODS Longitudinal data were used to calculate incidence of first-event post-release OAT discontinuation among men released from prison receiving OAT, and single-event discrete-time survival methods were used to estimate associations with post-release OAT discontinuation. RESULTS Among 110 participants, 55 OAT discontinuations were observed in the two years post-release, an overall crude incidence rate (IR) of 46 per 100 person-years (PY) (95 % confidence interval [95 %CI]: 36-60 per 100PY). Incidence was greatest between release from prison and first follow-up (IR: 84 per 100PY, 95 %CI: 62-116 per 100PY). Initiating OAT during index imprisonment (versus transitioning from community OAT; adjusted hazard rate [AHR]: 2.17, 95 %CI: 1.14-4.13) and identifying as Aboriginal and/or Torres Strait Islander (AHR: 4.95, 95 %CI: 2.00-12.25) were associated with an increased hazard of OAT discontinuation. CONCLUSION In a cohort of men with recent histories of IDU released from prison receiving OAT, half reported OAT discontinuation within two years of release from prison, with incidence of discontinuation greatest soon after prison-release. Targeted support for men who initiate OAT during episodes of imprisonment and Aboriginal and/or Torres Strait Islander peoples is necessary to reduce incidence of OAT discontinuation among people at greatest risk of discontinuation.

Abstract
Background National health monitoring agencies have reported the alternative use of morphine sulfate painkiller for maintenance treatment of opioid use disorder (OUD), associated with a potential increase in overdose risk. Objectives This study sought to assess the prevalence of regular and occasional legally prescribed morphine use in patients treated for OUD and compare their characteristics to those of patients receiving conventional opioid maintenance treatment (OMT), buprenorphine or methadone. Then, we assessed the factors associated with opioid overdose risk. Methods Data were extracted from the French national healthcare system database, covering the entire population in 2015. Diagnosis associated with hospital discharge and long-term disease codes were extracted to select the population and identify outcomes and covariates. OUD non-chronic pain patients were divided into regular (≤35 days between dispensing and ≥3 months of continuous treatment duration) morphine users, and occasional users. Their sociodemographic and health characteristics were compared to OMT controls. A multivariate logistic regression model was performed to determine factors associated with opioid overdose. Results In patients treated for OUD, 2,237 (2.2%) morphine users (1,288 regular and 949 occasional), 64,578 (63.7%) buprenorphine and 34,638 (34.1%) methadone controls were included. The prevalence of regular morphine use among patients treated for OUD regularly receiving an opioid was 1.3%. Compared to users who receive morphine regularly, occasional users had an increased risk of overdose [OR = 2.2 (1.5-3.3)], while the risk was reduced in the buprenorphine group [OR = 0.5 (0.4-0.7)] and not significantly different for methadone [OR = 1.0 (0.7-1.4)]. Other overdose risk factors were low-income, comorbidity, i.e., psychiatric conditions, alcohol use disorder or complications related to intravenous drug use, and coprescription with benzodiazepines or pregabalin. These factors were more frequent in morphine groups. Conclusions Patients that were prescribed oral morphine represented a small minority of the treated for OUD. The poorer health condition affected by numerous comorbidities and higher risk of opioid overdose in patients treated with oral morphine compared with OMT controls points toward the need to better supervise the practices of these patients, to strengthen multidisciplinary care and risk reduction measures.

Abstract
INTRODUCTION Several pharmacotherapeutic interventions are available for maintenance treatment for opioid-related disorders. However, previous meta-analyses have been limited to pairwise comparisons of these interventions, and their efficacy relative to all others remains unclear. Our objective was to unify findings from different healthcare practices and generate evidence to strengthen clinical treatment protocols for the most widely prescribed medications for opioid-use disorders. METHODS We searched Medline, EMBASE, PsycINFO, CENTRAL, and ClinicalTrials.gov for all relevant randomized controlled trials (RCT) from database inception to February 12, 2022. Primary outcome was treatment retention, and secondary outcome was opioid use measured by urinalysis. We calculated risk ratios (RR) and 95% credible interval (CrI) using Bayesian network meta-analysis (NMA) for available evidence. We assessed the credibility of the NMA using the Confidence in Network Meta-Analysis tool. RESULTS Seventy-nine RCTs met the inclusion criteria. Due to heterogeneity in measuring opioid use and reporting format between studies, we conducted NMA only for treatment retention. Methadone was the highest ranked intervention (Surface Under the Cumulative Ranking [SUCRA] = 0.901) in the network with control being the lowest (SUCRA = 0.000). Methadone was superior to buprenorphine for treatment retention (RR = 1.22; 95% CrI = 1.06-1.40) and buprenorphine superior to naltrexone (RR = 1.39; 95% CrI = 1.10-1.80). However, due to a limited number of high-quality trials, confidence in the network estimates of other treatment pairs involving naltrexone and slow-release oral morphine (SROM) remains low. CONCLUSION All treatments had higher retention than the non-pharmacotherapeutic control group. However, additional high-quality RCTs are needed to estimate more accurately the extent of efficacy of naltrexone and SROM relative to other medications. For pharmacotherapies with established efficacy profiles, assessment of their long-term comparative effectiveness may be warranted. TRIAL REGISTRATION This systematic review has been registered with PROSPERO (https://www.crd.york.ac.uk/prospero) (identifier CRD42021256212).

Abstract
INTRODUCTION In response to a high burden of opioid use disorder (OUD), Iran established a network of opioid agonist treatment (OAT) centres beginning in 2002. To increase treatment diversity, particularly for patients who use opium as their drug of choice, opium tincture (OT)-assisted treatment was introduced to the network. This study aimed to explore factors influencing OT-assisted treatment selection for OUD in Tehran, Iran. METHODS We conducted 54 in-depth interviews with patients with OUD (n = 33), family members of patients (n = 9) and drug treatment providers (n = 12). Participants were recruited from 12 drug treatment centres across Tehran, between September and November 2019. All interviews were audio-recorded, transcribed and coded in OpenCode 4.02 software and analysed using thematic analysis. RESULTS Study participants more commonly reported individual-level factors as facilitators (e.g. to reduce harms associated with illicit opioid use, achieve recovery through a gradual dose reduction regimen combined with Congress 60 recovery program) and structural level factors (e.g. low adoption by OAT system and lack of familiarity of treatment providers) as barriers for utilisation of OT-assisted treatment regimens. OT was perceived to produce lower levels of physiological dependence than methadone, but the requirement for twice supervised dosing was restrictive. Low familial and community acceptance were also seen as barriers to access. DISCUSSION AND CONCLUSIONS This research identified a range of perceived benefits for OT-assisted treatment ranging from harm reduction to an intermediate step to achieve recovery. However, several structural-, individual-, familial- and community-level barriers impede its availability and acceptability.

Abstract
BACKGROUND Some countries have used opioid agonist medications other than methadone and buprenorphine as a strategy to increase treatment diversity. In Iran and other countries where opium use is common and culturally tolerated, opium tincture (OT) has gained growing popularity and been approved to treat opioid use disorder (OUD). Given the increasing interest in this intervention, we conducted a systematic review of the literature to evaluate the safety and efficacy of OT-assisted treatment for OUD. METHODS We systematically searched international (MEDLINE, Embase, CINAHL, PsychInfo, Google Scholar, and clinicaltrials.gov) and Iranian (Scientific Information Database (SID), Iranmedex, IranDoc, digital library of Iran's Drug Control Headquarters and the Iranian Registry for Clinical Trials) databases on November 04, 2020 without any language or publication date limitations. Two reviewers screened the titles, abstracts, and full-text of the retrieved records to find clinical trials or observational studies that assessed the safety and efficacy of OT-assisted treatment for OUD. RESULTS We screened 1301 records and included 21 unique studies on assisted withdrawal (n = 5), maintenance (n = 9), and gradual dose reduction (n = 7) treatment regimens. Most studies included men and people with opium use disorder. We found only six randomized controlled trials (RCT). Our results showed that OT-assisted treatment is associated with comparable outcomes with methadone treatment in both assisted withdrawal and maintenance treatment regimens. We also found promising results for using gradual dose reduction regimen of OT-assisted treatment from observational studies. The overall quality of scientific evidence was low due to the limited number RCT and high risk of bias in the included studies. CONCLUSIONS The body of evidence supporting the safety and efficacy of OT-assisted treatment in assisted withdrawal, maintenance, and gradual dose reduction regimens is limited but somewhat promising, in particular among people with opium use disorder. Our review calls for higher-quality studies to investigate the comparative efficacy of these treatment methods with standard pharmacotherapies for OUD.

Abstract
Background: There is a knowledge gap in systematic reviews on the impact of opioid agonist treatments on mental health.Objectives: We compared mental health outcomes between different opioid agonist treatments and placebo/waitlist, and between the different opioids themselves.Methods: This meta-analysis of randomized clinical trials (RCTs) was pre-registered at PROSPERO (CRD42018109375). Embase, MEDLINE, PsychInfo, CINAHL Complete, and Web of Science Core Collection were searched from inception to May 2020. RCTs were included if they compared opioid agonists with each other or with placebo/waitlist in the treatment of patients with opioid use disorder and reported at least one mental health outcome after 1-month post-baseline. Studies with psychiatric care, adjunct psychotropic medications, or unbalanced psychosocial services were excluded. The primary outcome was overall mental health symptomatology, e.g. Symptom Checklist 90 total score, between opioids and placebo/waitlist. Random effects models were used for all the meta-analyses.Results: Nineteen studies were included in the narrative synthesis and 15 in the quantitative synthesis. Hydromorphone, diacetylmorphine (DAM), methadone, slow-release oral morphine, buprenorphine, and placebo/waitlist were among the included interventions. Based on the network meta-analysis for primary outcomes, buprenorphine (SMD (CI95%) = -0.61 (-1.20, -0.11)), DAM (-1.40 (-2.70, -0.23)), and methadone (-1.20 (-2.30, -0.11)) were superior to waitlist/placebo on overall mental health. Further direct pairwise meta-analysis indicated that overall mental health improved more in DAM compared to methadone (-0.23 (-0.34, -0.13)).Conclusions: Opioid agonist treatments used for the treatment of opioid use disorder improve mental health independent of psychosocial services.

Abstract
INTRODUCTION Since April 2015, slow-release oral morphine (SROM) has been approved for opioid agonist treatment (OAT) in Germany. Experimental studies show that benefits of SROM over methadone include less heroin craving, better tolerability, and higher patient satisfaction and mental stability. The SROMOS study (Efficacy and Tolerability of Slow-Release Oral Morphine in Opioid Substitution Treatment) aims to investigate the long-term effects (effectiveness and safety) of morphine substitution under routine care in Germany. MATERIAL AND METHODS This is a prospective, noninterventional, naturalistic, observational study. Between July 2016 and November 2017, this study recruited patients in OAT who decided to switch to SROM from 23 outpatient addiction treatment centers in Germany. The study collected data on mental health (Brief Symptom Inventory - BSI-18), substance use, somatic health (Opiate Treatment Index Health-Symptoms-Scale - OTI-HSS), opioid craving (visual analogue scale), and withdrawal symptoms (Short Opiate Withdrawal Scale) at baseline (t0) and after 3 (t3), 6 (t6) and 12 (t12) months. Physicians documented side effects as adverse events (AEs) and adverse drug reactions (ADRs). RESULTS Three-quarters of the enrolled study participants (N = 180) were male. The average age was 44.4 years. Patients were opioid-dependent for 23 years and had been in OAT for almost seven years on average. After 12 months, 60.6% were still being treated with SROM. Mental health improved significantly under SROM treatment between t0 and t12. The intention-to-treat (ITT), as well as the per-protocol (PP) analysis, shows a statistically significant improvement of the mean Global Severity Index (GSI) of the BSI-18 value of 20% (ITT) and 24% (PP). Physical health also improved significantly under SROM treatment. There were no statistically significant changes in the use of cannabis, cocaine, amphetamines, and tranquillizers in the past 30 days, but heroin use, intravenous consumption, and the number of drinking days significantly decreased. CONCLUSIONS This study provides some of the first long-term data on OAT with SROM under routine care conditions. SROM treatment is an effective alternative for a subgroup of opioid-dependent patients with an unsatisfactory course of OAT or in cases where undesirable side effects due to alternative substances have occurred. ETHICAL STATEMENT The study protocol was approved by the Ethics Committee of the Chamber of Physicians in Hamburg in March 2016 (No. PV5222). The study was conducted by following the Declaration of Helsinki and is registered with the German Register of Clinical Trials (DRKS, ID: DRKS00010712).

Abstract
BACKGROUND Retention in care is a prerequisite for successful recovery, especially for a chronic condition like opioid dependence. Though retention varies greatly depending on the different substitution medication and treatment model, treatment retention is used as an indicator of treatment quality and effectiveness of care on a system and individual level. To monitor the overall quality of the Austrian opioid agonist treatment (OAT) system and to monitor patient satisfaction within the system, a new online-based registry called "eSuchmittel" was introduced in Austria at the beginning of 2011. The objective of this study is to analyze retention rates within the Austrian treatment system and to identify patient characteristics associated with retention, using data collected by the substitution registry. METHODS The complete Austrian sample of 4778 registered patients starting treatment between 1.1.2011 to 31.12.2012 were included in the prospective cohort study using data from the Austrian substitution registry. For the statistical analysis, multivariate Cox Regression and Kaplan-Meier survival analysis were used to evaluate retention in treatment. RESULTS The retention rate of the total cohort after two years was around 61%. Retention rates were significantly lower for men (exp(B) = .806, 95% CI 0.714-0.908) and significantly higher for patients aged 30 and older (exp(B) = 1.155, 95% CI 1.044-1.279), among patients located in Vienna (exp(B) = 1.439, 95% CI 1.273-1.626) and among patients prescribed oral slow-release morphine (SROM) (exp(B) = 2.141, 95% CI 1.885-2.430). CONCLUSIONS Average retention in the Austrian system is high in comparison to international retention rates. Nationally, SROM demonstrates higher treatment retention when compared to other available substitution medications. Sociodemographic and regional indicators also contribute to higher retention in care. A systematic monitoring of retention rates within a national registry is an important tool helping to evaluate the quality of care. In this study, the Austrian OAT system proves very high retention in care, an important success criterion.

Risk assessment of using off-label morphine sulfate in a population-based retrospective cohort of opioid-dependent patients. Br J Clin Pharmacol 2020; 86:2338-2348. [PMID: 31389036 PMCID: PMC7688539 DOI: 10.1111/bcp.14082] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2018] [Revised: 05/02/2019] [Accepted: 07/19/2019] [Indexed: 01/09/2023] Open
Abstract
AIMS Several addictovigilance studies have described the off-label use of morphine sulfate (MS) for nonchronic pain in opioid use disorder (OUD) patients as an alternative to conventional opioid substitution treatments (OSTs). This study primarily sought to compare the incidence of unintentional opioid-related overdose in the year following the prescription initiation in off-label MS users, compared to OST-maintained patients. METHODS Sequential cohorts of OUD patients who were regularly dispensed MS, buprenorphine, or methadone, between 1 April 2012 and 31 December 2014, were retrospectively identified using the French nationwide healthcare data system. The incidence of overdoses, deaths, doctor shopping, and complications of a viral, bacterial or thrombotic nature, was compared using the Cox regression method. RESULTS Overall, 1075, 20 834 and 9778 OUD patients without chronic-pain were included in the MS, buprenorphine, and methadone cohorts, respectively. Overdose incidence was 3.8 (P < .01 [95% confidence interval (CI): 2.1-6.8]) and 2.0 (P = .02 [95%CI: 1.1-3.6]) higher in the MS cohort vs buprenorphine and methadone, respectively. Death incidence was 9.1 (P < .01 [95%CI: 3.2-25.9]) and 3.9 (P < .01 [95%CI: 1.4-10.7]) higher in the MS cohort vs buprenorphine and methadone, respectively. The incidences of other associated risks were significantly higher in the MS group vs OSTs, except for hepatitis C viral infection and thrombotic complications. CONCLUSION This first French comprehensive nationwide study reveals increasing overdose, death, bacterial infection, abuse and diversion risks when off-label MS is initiated as alternative to OST. These results question the relevance of prescribing MS as a safe opioid maintenance treatment, considering its health risk profile.

Abstract
AIMS The primary objective of this study was to investigate whether the fatalities of opioid abuse are not only related to respiratory depression but also as a result of other side effects such as emesis, delayed gastric emptying, a reduction of the cough reflex, and impaired consciousness leading to the aspiration of gastric contents, a finding regularly observed in drug-related deaths. DESIGN A retrospective exploratory study analyzing heroin/morphine/methadone-related deaths submitted to court-ordered autopsy. SETTING Center for Forensic Medicine, Medical University of Vienna, Austria (2010-2015). PARTICIPANTS Two hundred thirty-four autopsy cases were included in the study: morphine (n = 200), heroin (n = 11), and methadone (n = 23) intoxication. FINDINGS Analyses revealed that 41.88% of all deceased showed aspiration of gastric contents with equal gender distribution (p = 0.59). Aspiration was more frequent in younger deceased (χ2 = 8.7936; p = 0.012) and in deceased with higher body mass index (BMI) (χ2 = 6.2441; p = 0.044). Blood opioid concentration was lower in deceased with signs of aspiration than in non-aspirators (p = 0.013). Toxicological evaluation revealed a high degree of concomitant substance abuse (91%)-benzodiazepines (61.6%) and/or alcohol (21.8%). CONCLUSIONS There are lower opioid concentrations in deceased with signs of aspiration, a fact which strongly points to aspiration as alternative cause of death in opioid-related fatalities. Furthermore, this study highlights the common abuse of slow-release oral morphine in Vienna and discusses alternative medications in substitution programs (buprenorphine/naloxone or tamper-resistant slow-release oral morphine preparations), as they might reduce intravenous abuse and opioid-related deaths.

Abstract
Amidst the opioid overdose crisis, there are increased efforts to expand access to medications for opioid use disorder (MOUD). Hospitalization for the complications of substance use in the United States (US) provides an opportunity to initiate methadone, buprenorphine, and extended release naltrexone and link high-risk, not otherwise engaged, patients into outpatient care. However, treatment options for patients are quickly exhausted when these medications are not desired, tolerated, or beneficial. As an example, we discuss the case of a man who was hospitalized 27 times over 2 years for complications related to his opioid use disorder (OUD), including recurring methicillin-resistant Staphylococcus aureus vertebral osteomyelitis, increasing antimicrobial resistance, new infections, and multiple overdoses in and out of the hospital. The patient suffered these complications despite efforts to treat his OUD with methadone and buprenorphine while hospitalized, and repeated attempts to link him to outpatient care. We use this case to review evidence-based treatments for refractory OUD, which are not approved in the US, but are available in Canada. If hospitalized in Vancouver, Canada, this patient could have been offered slow-release oral morphine and injectable opioid agonist therapy, as well as access to sterile syringes and injection equipment at an in-hospital supervised injection facility. Each of these approaches is supported by evidence and has been implemented successfully in Canada, yet none are available in the US. In order to combat the multiple harms from opioids, it is critical that we consider every evidence-based tool.

Abstract
Drugs of abuse, such as opiates, have been widely associated with diminishing host-immune responses, including suppression of HIV-specific antibody responses. In particular, periodic intake of the drugs of abuse can result in time-varying periodic antibody level within HIV-infected individuals, consequently altering the HIV dynamics. In this study, we develop a mathematical model to analyze the effects of periodic intake of morphine, a widely used opiate. We consider two routes of morphine intake, namely, intravenous morphine (IVM) and slow-release oral morphine (SROM), and integrate several morphine pharmacodynamic parameters into HIV dynamics model. Using our non-autonomous model system we formulate the infection threshold, Ri, for global stability of infection-free equilibrium, which provides a condition for avoiding viral infection in a host. We demonstrate that the infection threshold highly depends on the morphine pharmacodynamic parameters. Such information can be useful in the design of antibody-based vaccines. In addition, we also thoroughly evaluate how alteration of the antibody level due to periodic intake of morphine can affect the viral load and the CD4 count in HIV infected drug abusers.

Abstract
The aims of this study were to evaluate the effects on opioid medication prescribing, patient opioid safety education, and prescribing of naloxone following implementation of a Safer Opioid Prescribing Protocol (SOPP) as part of the electronic health record (EHR) system at a Level I trauma center. This was a prospective observational study of the EHR of trauma patients pre- (n = 191) and post-(n = 316) SOPP implementation between 2014 and 2016. At a comparison Level I trauma site not implementing SOPP, EHRs for the same time period were assessed for any historical trends in opioid and naloxone prescribing. After SOPP implementation, the implementation site increased the use of nonnarcotic pain medication, decreased dispensing high opioid dose (≥100 MME [milligram morphine equivalent]), significantly increased the delivery of opioid safety education to patients, and initiated prescribing naloxone. These changes were not found in the comparison site. Opioid prescribing for acute pain can be effectively reduced in a busy trauma setting with a guideline intervention incorporated into an EHR. Guidelines can increase the use of nonnarcotic medications for the treatment of acute pain and increase naloxone coprescription for patients with a higher risk of overdose.

Abstract
Aims Oral opioid preparations combined with naloxone are intended to induce a transient acute withdrawal syndrome to avoid intravenous misuse. This trial aimed to establish an appropriate morphine–naloxone dose ratio for an abuse‐deterrent oral opioid formulation. Methods In a randomized, double‐blinded, 2 × 2 cross‐over trial, 43 patients with opioid use disorder were challenged with intravenous morphine HCl Ph.Eur. (75 mg; [morphine mono]) or morphine HCl Ph.Eur. and naloxone HCl Ph.Eur. at ratios of 100:1 (75 mg: 0.75 mg; [morphine–naloxone 100:1]) or 200:1 (75 mg: 0.375 mg; [morphine–naloxone 200:1]). Acute naloxone‐induced opioid withdrawal was evaluated using subjective (Short Opiate Withdrawal Scale–German [SOWS‐G]) and observer‐rated (Objective Opiate Withdrawal Scale [OOWS], Wang scale) questionnaires, and physiological parameters. For statistical analysis, the area under the curve between baseline and 20 minutes after drug administration of the outcome variables was calculated. Results Intravenous morphine–naloxone caused rapid withdrawal symptoms. Coadministration of naloxone dose‐dependently (morphine–naloxone 100:1 > morphine–naloxone 200:1) increased SOWS‐G, OOWS and Wang Scale area under the curve when compared to morphine mono, respectively (all P < .0001). A similar response was detectable for changes of pupil diameter. Blood pressure and respiratory rate changed heterogeneously, and heart rate was unaltered by morphine without or with naloxone. Conclusion Morphine–naloxone 100:1 effectively suppresses the pleasurable effects of intravenous morphine and results in an aversive withdrawal reaction. A lower naloxone concentration as used in morphine–naloxone 200:1 does not appear to be appropriate to prevent intravenous morphine misuse.

Abstract
Opioid use disorder (OUD) is a chronic relapsing disorder that, whilst initially driven by activation of brain reward neurocircuits, increasingly engages anti-reward neurocircuits that drive adverse emotional states and relapse. However, successful recovery is possible with appropriate treatment, although with a persisting propensity to relapse. The individual and public health burdens of OUD are immense; 26.8 million people were estimated to be living with OUD globally in 2016, with >100,000 opioid overdose deaths annually, including >47,000 in the USA in 2017. Well-conducted trials have demonstrated that long-term opioid agonist therapy with methadone and buprenorphine have great efficacy for OUD treatment and can save lives. New forms of the opioid receptor antagonist naltrexone are also being studied. Some frequently used approaches have less scientifically robust evidence but are nevertheless considered important, including community preventive strategies, harm reduction interventions to reduce adverse sequelae from ongoing use and mutual aid groups. Other commonly used approaches, such as detoxification alone, lack scientific evidence. Delivery of effective prevention and treatment responses is often complicated by coexisting comorbidities and inadequate support, as well as by conflicting public and political opinions. Science has a crucial role to play in informing public attitudes and developing fuller evidence to understand OUD and its associated harms, as well as in obtaining the evidence today that will improve the prevention and treatment interventions of tomorrow.

Abstract
Background Given the complex nature of opioid addiction treatment and the rising number of available opioid substitution and antagonist therapies (OSAT), there is no ‘gold standard’ measure of treatment effectiveness, and each successive trial measures a different set of outcomes which reflect success in arbitrary or opportune terms. We sought to describe the variation in current outcomes employed across clinical trials for opioid addiction, as well as determine whether a discrepancy exists between the treatment targets that patients consider important and how treatment effectiveness is measured in the literature. Methods We searched nine commonly used databases (e.g., EMBASE, MEDLINE) from inception to August 1, 2015. Outcomes used across trials were extracted and categorized according to previously established domains. To evaluate patient-reported goals of treatment, semi-structured interviews were conducted with 18 adults undergoing methadone treatment. Results We identified 60 trials eligible for inclusion. Once outcomes were categorized into eight broad domains (e.g., abstinence/substance abuse), we identified 21 specific outcomes with furthermore 53 subdomains and 118 measurements. Continued opioid use and treatment retention were the most commonly reported measures (46%, n = 28). The majority of patients agreed that abstinence from opioids was a primary goal in their treatment, although they also stressed goals under-reported in clinical trials. Conclusions There is inconsistency in the measures used to evaluate the effectiveness of OSATs. Individual and population level decision making is being guided by a standard of effect considered useful to researchers yet in direct conflict with what patients deem important.

Abstract
In 2017, the US Department of Health and Human Services declared a public health emergency on the opioid crisis. On average, 115 Americans die each day from an opioid overdose. The scope and breadth of this problem is continually evolving. In 2010, there was a shift in causes primarily due to the use of heroin, and currently the latest shift in opioid-related deaths involves a variety of synthetic opioids, particularly illicitly manufactured fentanyl. As the medical, sociological and political environments have drastically changed, especially in the USA, over the last 6 years with regard to opioid use and misuse, an updated review of the literature was necessary.

Abstract
OBJECTIVE To assess the efficacy of slow release oral morphine (SROM) as a treatment for opioid use disorder (OUD). DESIGN Systematic review and meta-analysis of randomised controlled trials (RCTs). DATA SOURCES Three electronic databases were searched through 1 May 2018: the Cochrane Central Register of Controlled Trials, MEDLINE and EMBASE. We also searched the following electronic registers for ongoing trials: ClinicalTrials.gov, WHO International Clinical Trials Registry Platform, Current Controlled Trials and the EU Clinical Trials Register. ELIGIBILITY CRITERIA FOR SELECTING STUDIES We included RCTs of all durations, assessing the effect of SROM on measures of treatment retention, heroin use and craving in adults who met the diagnostic criteria for OUD. DATA EXTRACTION AND SYNTHESIS Two independent reviewers extracted data and assessed risk of bias. Data were pooled using the random-effects model and expressed as risk ratios (RRs) or mean differences with 95% CIs. Heterogeneity was assessed (χ2 statistic) and quantified (I2 statistic) and a sensitivity analysis was undertaken to assess the impact of particular high-risk trials. RESULTS Among 1315 records screened and four studies reviewed, four unique randomised trials met the inclusion criteria (n=471), and compared SROM with methadone. In the meta-analysis, we observed no significant differences between SROM and methadone in improving treatment retention (RR=0.98; 95%CI: 0.94 to 1.02, p=0.34) and heroin use (RR=0.96; 95% CI: 0.61 to 1.52, p=0.86). Craving data was not amenable to meta-analysis. Available data implied no differences in adverse events, heroin, cocaine or benzodiazepine use. CONCLUSIONS Meta-analysis of existing randomised trials suggests SROM may be generally equal to methadone in retaining patients in treatment and reducing heroin use while potentially resulting in less craving. The methodological quality of the included RCTs was low-to-moderate.

Abstract
AIMS In France, a non-negligible proportion of opioid-dependent individuals inject morphine sulfate. Although it has not yet been officially approved as an opioid substitution treatment (OST), some physicians can prescribe its use for people in methadone or buprenorphine treatment failure. Longitudinal data from the ANRS-AERLI study, which evaluated an educational intervention for safer injection called AERLI, provided us the opportunity to better characterize the profile, risk practices and needs of people who inject morphine sulfate (MSI), through comparison with other injectors, and to identify correlates of HIV/HCV risk practices in this group. METHODS The national multisite ANRS-AERLI study assessed the impact of AERLI offered in volunteer harm reduction (HR) centers ("with intervention") (n = 113) through comparison with standard HR centers ("without intervention") (n = 127). All participants were scheduled to be followed up for 12 months and have 3 telephone interviews: at baseline, 6 months and 12 months. We compared MSI (n = 79) with other opioid injectors (n = 161) and then used a mixed logistic model to identify factors associated with HIV/HCV risk practices among MSI. FINDINGS Of the 240 eligible participants, 79 were regular MSI. They were less likely to use cocaine, crack or buprenorphine and to receive OST than other participants. Conversely, MSI were more likely to inject drugs more than three times a day and to report HIV/HCV risk practices. Among MSI, multivariate analysis showed that those receiving morphine sulfate as an OST were less likely to report such practices than other participants (aOR [95%CI] = 0.11 [0.02-0.61]). CONCLUSION Our results show that while MSI use fewer stimulants, they have more HIV/HCV risk practices than other injectors. However, when MSI are prescribed morphine sulfate as a treatment, these practices tend to decrease. Our findings suggest the importance of increasing access to morphine sulfate as a new OST in France.

Abstract
SummaryOver the past decade, important research has been performed into the therapeutic use of dihydrocodeine, injectable opioids (diamorphine) and supervised disulfiram in addiction treatment. There have also been interesting developments regarding baclofen for alcohol problems and use of stimulants in adult Attention-deficit hyperactivity disorder (ADHD). However, evidence for the effectiveness of medication to promote alcohol abstinence remains modest at best.

Abstract
BACKGROUND Opioid medication to treat acutely injured patients is usual care in trauma settings. A higher prevalence of alcohol and other substance misuse in this population compared to the general population increases the vulnerability of such patients to both misuse of their prescribed opioids, and also unintentional opioid overdose. The primary purpose of this study was to assess the prevalence of substance use and unintentional opioid overdose risk among acutely injured trauma patients, and to examine the frequency and predictors of high opioid dose at discharge. METHODS A retrospective electronic medical record (EMR) review of three-months of data from two Level 1 trauma centers. We assessed the prevalence of substance misuse, unintentional opioid overdose risk, and presence of documentation of clinical strategies to mitigate these risks, such as co-prescription of the opioid agonist naloxone. RESULTS In total, 352 patient EMRs were examined. Over 40% of the patients reviewed had at least one indication of substance misuse (42.5% [95%CI: 37.3, 47.7]); at least 1 unintentional opioid overdose risk factor was identified in 240 EMR reviewed (68.2% [95%CI: 63.3, 73.1]). Dose of opioid medication was not significantly different for patients with substance misuse versus those without. There was no co-prescription of naloxone for any of the discharged patients. CONCLUSIONS Our results indicate that despite the high rates of substance misuse, the potential for misuse, dependence and unintentional overdose risk from prescribed opioid medications are prevalent among acutely injured trauma patients. Prescribing after acute trauma care should address these risk factors.

Abstract
During the past decade, substantial progress has been made in the field of addiction medicine in Europe, particularly regarding the development of new treatment interventions, resulting in a wide range of therapeutic options for patients with substance use disorders. However, not all interventions are evidence based. Patients with cannabis and cocaine/amphetamine use disorders and special patient populations especially lack evidence-based treatment recommendations. Many patients undergo treatment that has not been scientifically evaluated for quality and efficacy. Moreover, there are large disparities regarding availability and treatment access across Europe, with the new member states of the European Union (EU) reporting long waiting lists and low treatment coverage. Even in Austria, which ranks among the countries with relatively high treatment coverage and good diversification of treatment in opioid maintenance therapy due to the availability of methadone, buprenorphine, and slow-release oral morphine (SROM), a considerable population of untreated or inadequately treated patients exists. Treatment for substance use disorders in Europe still has scope for improvement in terms of treatment availability and access, which is ideally provided by further development and implementation of evidence-based interventions.

Abstract
BACKGROUND While a number of pharmacological interventions exist for the treatment of opioid use disorder, evidence evaluating the effect of pain on substance use behavior, attrition rate, and physical or mental health among these therapies has not been well established. We aim to evaluate these effects using evidence gathered from a systematic review of studies evaluating chronic non-cancer pain (CNCP) in patients with opioid use disorder. METHODS We searched the Medline, EMBASE, PubMed, PsycINFO, Web of Science, Cochrane Database of Systematic Reviews, ProQuest Dissertations and theses Database, Cochrane Central Register of Controlled Trials, World Health Organization International Clinical Trials Registry Platform Search Portal, and National Institutes for Health Clinical Trials Registry databases to identify articles evaluating the impact of pain on addiction treatment outcomes for patients maintained on opioid agonist therapy. RESULTS Upon screening 3,540 articles, 14 studies with a combined sample of 3,128 patients fulfilled the review inclusion criteria. Results from the meta-analysis suggest that pain has no effect on illicit opioid consumption [pooled odds ratio (pOR): 0.70, 95%CI 0.41–1.17; I2 = 0.0] but a protective effect for reducing illicit non-opioid substance use (pOR: 0.57, 95%CI 0.41–0.79; I2 = 0.0). Studies evaluating illicit opioid consumption using other measures demonstrate pain to increase the risk for opioid abuse. Pain is significantly associated with the presence of psychiatric disorders (pOR: 2.18; 95%CI 1.6, 2.9; I2 = 0.0%). CONCLUSION CNCP may increase risk for continued opioid abuse and poor psychiatric functioning. Qualitative synthesis of the findings suggests that major methodological differences in the design and measurement of pain and treatment response outcomes are likely impacting the effect estimates.

Abstract
BACKGROUND Opioid maintenance treatment is the option of choice to stabilize opioid-dependent patients. Whilst efficacy of methadone and buprenorphine has been studied extensively, fewer data on slow-release oral morphine are available. AIMS This study analyzes the effects of slow-release oral morphine compared to methadone with regard to self-reported mental symptoms, drug use and satisfaction with treatment. METHODS The study was carried out as an open-label randomized crossover trial in 14 treatment sites in Switzerland and Germany. It comprised 2 crossover periods of 11 weeks each. For measuring mental symptoms, the Symptom Checklist-27 (SCL-27) was used. Drug and alcohol use was assessed by the number of consumption days, and treatment satisfaction by a visual analogue scale. RESULTS A total of 157 patients were included for the analyses (per-protocol sample). Statistically significantly better outcomes for morphine as compared to methadone treatment were found for overall severity of mental symptoms (SCL-27 Global Severity Index), as well as 5 of the 6 syndrome groups of the SCL-27, and for treatment satisfaction. There were no statistically significant differences with regard to drug or alcohol use between groups. CONCLUSIONS This study supports positive effects of slow-release oral morphine compared to methadone on patient-reported outcomes such as mental symptoms and treatment satisfaction with comparable effects on concomitant drug use. Slow-release oral morphine represents a meaningful alternative to methadone for treatment of opioid dependence.

Abstract
BACKGROUND AND OBJECTIVES Evidence suggests that methadone may play a protective role in the faulty decision-making in heroin-addicted individuals. This may reduce craving for opioids and the risky decisions associated with active opioid use. METHODS We tested the effect of a daily therapeutic dose of methadone on faulty decision-making in eighty (n = 80) individuals with a history of opioid addiction. We used the Iowa Gambling Task (IGT) and compared the score and response time before and after the daily methadone dosing. RESULTS The mean net IGT score before methadone dose was 10 (±22) and 22 (±23) after methadone dose (t = 4.23, p = .00006). These results reflect statistically significant improvement in faulty decisions after the administration of the daily methadone dose. The mean response time for the reward cards before methadone dose were 1,856 ms (±871) and 1,465 ms (±851) after methadone dose (t = 2.55, p = .012). The mean response time for the punishment cards before methadone dose were 1,688 ms (±911) and 1,399 ms (±827) after methadone dose (t = 1.86, p = .065). These results reflect statistically significant improvement in response time to a rewarding healthy decisions after the administration of the daily methadone dose. CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE This is the first study to report the effect of a therapeutic dose of methadone on improving faulty decisions for individuals with a long history of opioids addiction. This study demonstrated that the time to making a healthy decision was significantly shorter as a result of administration of methadone.

Abstract
Scant scientific evidence supports the efficacy of acupuncture in the treatment of opiate dependence. The purpose of this study was to examine the effectiveness of acupuncture for heroin addicts on methadone maintenance by measuring the daily consumption of methadone, variations in the 36-item Short Form Health Survey-36 (SF-36) and Pittsburgh Sleep Quality Index (PSQI) scores, and heroin craving. Sixty heroin addicts were randomly assigned to true acupuncture (electroacupuncture at the Hegu [LI4] and Zusanli [ST36] acupoints, as well as acupuncture at the Ear Shenmen) or sham acupuncture (minimal acupuncture at the Hegu and Zusanli acupoints without electrical stimulation and superficial acupuncture at the Ear Shenmen), twice weekly for 4 weeks. From week 2 onwards, the daily dose of methadone was reduced by a significantly greater amount with true acupuncture compared with sham acupuncture. True acupuncture was also associated with a greater improvement in sleep latency at follow-up. All adverse events were mild in severity. Acupuncture appears to be a useful adjunct to methadone maintenance therapy (MMT) in heroin addiction.

Maintenance treatment for opioid dependence with slow-release oral morphine: a randomized cross-over, non-inferiority study versus methadone. Addiction 2014; 109:617-26.

Abstract
AIMS To compare the efficacy of slow-release oral morphine (SROM) and methadone as maintenance medication for opioid dependence in patients previously treated with methadone. DESIGN Prospective, multiple-dose, open label, randomized, non-inferiority, cross-over study over two 11-week periods. Methadone treatment was switched to SROM with flexible dosing and vice versa according to period and sequence of treatment. SETTING Fourteen out-patient addiction treatment centres in Switzerland and Germany. PARTICIPANTS Adults with opioid dependence in methadone maintenance programmes (dose ≥50 mg/day) for ≥26 weeks. MEASUREMENTS The efficacy end-point was the proportion of heroin-positive urine samples per patient and period of treatment. Each week, two urine samples were collected, randomly selected and analysed for 6-monoacetyl-morphine and 6-acetylcodeine. Non-inferiority was concluded if the two-sided 95% confidence interval (CI) in the difference of proportions of positive urine samples was below the predefined boundary of 10%. FINDINGS One hundred and fifty-seven patients fulfilled criteria to form the per protocol population. The proportion of heroin-positive urine samples under SROM treatment (0.20) was non-inferior to the proportion under methadone treatment (0.15) (least-squares mean difference 0.05; 95% CI = 0.02, 0.08; P > 0.01). The 95% CI fell within the 10% non-inferiority margin, confirming the non-inferiority of SROM to methadone. A dose-dependent effect was shown for SROM (i.e. decreasing proportions of heroin-positive urine samples with increasing SROM doses). Retention in treatment showed no significant differences between treatments (period 1/period 2: SROM: 88.7%/82.1%, methadone: 91.1%/88.0%; period 1: P = 0.50, period 2: P = 0.19). Overall, safety outcomes were similar between the two groups. CONCLUSIONS Slow-release oral morphine appears to be at least as effective as methadone in treating people with opioid use disorder.

Abstract
BACKGROUND Opioid substitution treatments are effective in retaining people in treatment and suppressing heroin use. An open question remains whether slow-release oral morphine (SROM) could represent a possible alternative for opioid-dependent people who respond poorly to other available maintenance treatments. OBJECTIVES To evaluate the efficacy of SROM as an alternative maintenance pharmacotherapy for the treatment of opioid dependence. SEARCH METHODS We searched Cochrane Drugs and Alcohol Group's Register of Trials, Cochrane Central Register of Controlled Trials (CENTRAL - The Cochrane Library Issue 3, 2013), MEDLINE (January 1966 to April 2013), EMBASE (January 1980 to April 2013) and reference lists of articles. SELECTION CRITERIA Randomised controlled trials (RCTs) and quasi-randomised trials assessing efficacy of SROM compared with other maintenance treatment or no treatment. DATA COLLECTION AND ANALYSIS Two review authors independently selected articles for inclusion, extracted data and assessed risk of bias of included studies. MAIN RESULTS Three studies with 195 participants were included in the review. Two were cross-over trials and one was a parallel group RCT. The retention in treatment appeared superior to 80% in all the three studies (without significant difference with controls). Nevertheless, it has to be underlined that the studies had different durations. One lasted six months, and the other two lasted six and seven weeks. The use of opioids during SROM provision varied from lower to non-statistically or clinically different from comparison interventions, whereas there were no differences as far as the use of other substances was concerned.SROM seemed to be equal to comparison interventions for severity of dependence, or mental health/social functioning, but there was a trend for less severe opiate withdrawal symptoms in comparison with methadone (withdrawal score 2.2 vs. 4.8, P value = 0.06). Morphine was generally well tolerated and was preferred by a proportion of participants (seven of nine people in one study). Morphine appeared to reduce cravings, depressive symptoms (measured using the Beck Depression Inventory; P value < 0.001), physical complaints (measured using the Beschwerde-Liste (BL); P value < 0.001) and anxiety symptoms (P value = 0.008). Quality of life in people treated with SROM resulted in no significant difference or a worst outcome than in those taking methadone and buprenorphine. Other social functioning measures, such as finances, family and overall satisfaction, scored better in people maintained with the comparison substances than in those maintained with SROM. In particular, people taking methadone showed more favourable values for leisure time (5.4 vs. 3.7, P value < 0.001), housing (6.1 vs. 4.7, P value < 0.023), partnerships (5.7 vs. 4.2, P value = 0.034), friend and acquaintances (5.6 vs. 4.4, P value = 0.003), mental health (5.0 vs. 3.4, P value = 0.002) and self esteem (8.2 vs. 5.7, P value = 0.002) compared to people taking SROM; while people taking buprenorphine obtained better scores for physical health.Medical adverse events were consistently higher in people in SROM than in the comparison groups. None of the studies included people with a documented poor response to other maintenance treatment. AUTHORS' CONCLUSIONS The present review did not identify sufficient evidence to assess the effectiveness of SROM for opioid maintenance because only three studies meeting our inclusion criteria have been identified. Two studies suggested a possible reduction of opioid use in people taking SROM. In another study, the use of SROM was associated with fewer depressive symptoms. Retention in treatment was not significantly different among compared interventions while the adverse effects were more frequent with the people given SROM.

Abstract
Data from a national study of 345 privately funded, community-based substance use disorder (SUD) treatment centers were used to investigate social workers' knowledge, perceptions of effectiveness, and perceptions of the acceptability of medication assisted treatments (MATs) for SUDs. Results reveal the importance of exposure to MATs for social workers to develop a knowledge base regarding the effectiveness of various pharmacological agents. Results also underline the importance of social workers' perceptions of effectiveness in forming opinions regarding the acceptability of the use of MATs in SUD treatment. Lastly, a 12-Step orientation toward treatment has a negative influence on social workers' opinions regarding the acceptability of MATs.

Abstract
The British Association for Psychopharmacology guidelines for the treatment of substance abuse, harmful use, addiction and comorbidity with psychiatric disorders primarily focus on their pharmacological management. They are based explicitly on the available evidence and presented as recommendations to aid clinical decision making for practitioners alongside a detailed review of the evidence. A consensus meeting, involving experts in the treatment of these disorders, reviewed key areas and considered the strength of the evidence and clinical implications. The guidelines were drawn up after feedback from participants. The guidelines primarily cover the pharmacological management of withdrawal, short- and long-term substitution, maintenance of abstinence and prevention of complications, where appropriate, for substance abuse or harmful use or addiction as well management in pregnancy, comorbidity with psychiatric disorders and in younger and older people.

Abstract
Opioid dependence is a chronic relapsing condition which requires comprehensive care; pharmacological agents form the mainstay of its long term treatment. The two most popular approaches are the harm reduction method using agonists and the complete abstinence method using antagonists. Currently, particularly from the harm minimization perspective and the low feasibility of an abstinence based approach, there is an increasing trend toward agonist treatment. The use of buprenorphine has gained popularity in view of its safety profile and the availability of the buprenorphine-naloxone combination has made it popular as a take-home treatment. This review outlines the pharmacological advances and controversies in this area.

Abstract
Debates about which policy initiatives can prevent or reduce the damage that illicit drugs cause to the public good are rarely informed by scientific evidence. Fortunately, evidence-based interventions are increasingly being identified that are capable of making drugs less available, reducing violence in drug markets, lessening misuse of legal pharmaceuticals, preventing drug use initiation in young people, and reducing drug use and its consequences in established drug users. We review relevant evidence and outline the likely effects of fuller implementation of existing interventions. The reasoning behind the final decisions for action might be of a non-scientific nature, focused more on what the public and policy-makers deem of value. Nevertheless, important opportunities exist for science to inform these deliberations and guide the selection of policies that maximise the public good.

Abstract
This review article summarizes the results of all available clinical trials considering the use of slow-release oral morphine (SROM) for opioid maintenance treatment (OMT). All studies published up to October 2010 and assessing SROM for OMT in adult patients are included. Three independent reviewers assessed the selected articles using a standardized checklist. Study design, study length and number of subjects included were recorded. Data about retention rate (proportion of participants remaining under maintenance treatment at the end of the study), quality of life, withdrawal symptoms, craving, additional drug consumption, driving capacity and adverse events were collected. We identified 13 articles corresponding to nine clinical trials considering the use of SROM for OMT. Among them, only one was a randomized trial and one was a controlled not randomized trial. All other studies were uncontrolled. Retention rates were good (from 80.6 to 95%) with SROM maintenance, but similar retention rates were obtained with methadone. Most of the studies showed that quality of life, withdrawal symptoms, craving and additional drug consumption improved with SROM. However, there was no comparison with other maintenance drugs. As most of the studies assessing SROM efficacy were uncontrolled, there is no definite evidence that SROM is an effective alternative to methadone for OMT.

Abstract
Background Data from the US indicates that methadone-maintained populations are aging, with an increase of patients aged 50 or older. Data from European methadone populations is sparse. This retrospective cohort study sought to evaluate the age trends and related developments in the methadone population of Basel-City, Switzerland. Methods The study included methadone patients between April 1, 1995 and March 31, 2003. Anonymized data was taken from the methadone register of Basel-City. For analysis of age distributions, patient samples were split into four age categories from '20-29 years' to '50 years and over'. Cross-sectional comparisons were performed using patient samples of 1996 and 2003. Results Analysis showed a significant increase in older patients between 1996 and 2003 (p < 0.001). During that period, the percentage of patients aged 50 and over rose almost tenfold, while the proportion of patients aged under 30 dropped significantly from 52.8% to 12.3%. The average methadone dose (p < 0.001) and the 1-year retention rate (p < 0.001) also increased significantly. Conclusions Findings point to clear trends in aging of methadone patients in Basel-City which are comparable, although less pronounced, to developments among US methadone populations. Many unanswered questions on medical, psychosocial and health economic consequences remain as the needs of older patients have not yet been evaluated extensively. However, older methadone patients, just as any other patients, should be accorded treatment appropriate to their medical condition and needs. Particular attention should be paid to adequate solutions for persons in need of care.

Abstract
This article reviews the main pharmacotherapies that are currently being used to treat opioid addiction. Treatments include detoxification using tapered methadone, buprenorphine, adrenergic agonists such as clonidine and lofexidine, and forms of rapid detoxification. In opioid maintenance treatment (OMT), methadone is most widely used. OMT with buprenorphine, buprenorphine-naloxone combination, or other opioid agonists is also discussed. The use of the opioid antagonists naloxone (for the treatment of intoxication and overdose) and oral and sustained-release formulations of naltrexone (for relapse prevention) is also considered. Although recent advances in the neurobiology of addictions may lead to the development of new pharmacotherapies for the treatment of addictive disorders, a major challenge lies in delivering existing treatments more effectively. Pharmacotherapy of opioid addiction alone is usually insufficient, and a complete treatment should also include effective psychosocial support or other interventions. Combining pharmacotherapies with psychosocial support strategies that are tailored to meet the patients' needs represents the best way to treat opioid addiction effectively.

Abstract
BACKGROUND Little comparable information is available regarding clinical characteristics of opioid-dependent women from different countries. In the present study, women from the USA, Canada and a Central European country, Austria, screened for participation in the Maternal Opioid Treatment Human Experimental Research study, were compared with respect to their demographic and addiction histories. METHODS Pregnant women (n = 1,074) were screened for study participation using uniformed clinical criteria and instruments. The screening results were compared with regard to exclusion, demographics, drug use, and psychosocial and treatment histories. RESULTS Compared to the screened US and Canadian women, Austrian women were more likely to be younger (p < 0.001), white (p < 0.001), had significantly lower levels of educational attainment (p < 0.001), were less likely to use opioids daily (p < 0.001) and more likely to have been prescribed buprenorphine (p < 0.001). Compared to both rural and urban US groups, the Austrian group was less likely to have legal issues (p < 0.001) and was younger when first prescribed agonist medication (p < 0.001). CONCLUSION The differences between North American and European groups may offer unique insights concerning treatment and pregnancy outcomes for opioid-dependent pregnant women.

Drug Alcohol Depend 2009; 104:228-40. [PMID: 19608356 DOI: 10.1016/j.drugalcdep.2009.04.022] [Citation(s) in RCA: 40] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/13/2008] [Revised: 04/27/2009] [Accepted: 04/30/2009] [Indexed: 11/28/2022]
Abstract
OBJECTIVE Impairments in the function of attention exacerbate the course of opiate dependence and may play a role in the relapsing nature of the disorder. This study used clinical measures and positron emission tomography (PET) to assess the functioning of sustained attention in subjects with a history of opiate dependence. METHODS A test of auditory sustained attention was administered to 10 subjects receiving methadone maintenance treatment, 13 formerly opiate-dependent subjects in protracted abstinence, and 14 healthy Comparison subjects. Simultaneous measurement of regional glucose metabolism was made by [(18)F] flourodeoxyglucose PET. Subjects groups were compared on the measures of sustained attention and regional cerebral glucose metabolism. RESULTS Healthy Comparison subjects scored significantly better than either methadone-maintained or abstinent former opiate addicts on measures of sustained attention. Formerly opiate-dependent subjects in protracted abstinence scored better than methadone-maintained subjects on sustained attention. Methadone-maintained subjects demonstrated a relative reduction in regional cerebral glucose metabolism in the right supramarginal gyrus, and the thalamus bilaterally. The Comparison subjects without a history of opiate dependence demonstrated a relative increase in regional cerebral glucose metabolism in the right anterior cingulate gyrus, the right medial superior frontal gyrus and the thalamus bilaterally. CONCLUSIONS Subjects with a history of opiate dependence have impairments in the functioning of sustained attention, and abnormalities in brain regions identified as important in attention processing. Impairments in attention performance persist in subjects who enjoy prolonged abstinence from opiates.
