Study protocol for the Respond to Prevent Study: a multi-state randomized controlled trial to improve provision of naloxone, buprenorphine and nonprescription syringes in community pharmacies.
    Substance abuse, 2022, Volume: 43, Issue:1

    Access to the opioid antidote naloxone is a critical component of addressing the opioid crisis. Naloxone is a population-level prevention intervention associated with substantial reductions in overdose mortality and reduction of nonfatal overdose. Pharmacies' pivotal role in dispensing medications like buprenorphine for the treatment of opioid use disorder and selling nonprescription syringes places them at the crossroads of opioid access and risk mitigation methods like naloxone provision. Testing ways to optimize pharmacy-based naloxone provision will be key as the country expands the implementation of naloxone through the medical system. In the Respond to Prevent Study, we conducted a large, practical study of a pharmacy-focused intervention in a sample of Washington, Oregon, Massachusetts and New Hampshire community chain pharmacies to increase naloxone dispensing and improve opioid safety. The intervention integrated two evidence-based educational toolkits and streamlined materials to enhance the focus on naloxone policy, stigma reduction, and patient communications around naloxone, nonprescription syringes and buprenorphine access. The real-world study implemented a stepped wedge, clustered randomized trial design across 175 community chain pharmacies to evaluate the effectiveness of the Respond to Prevent intervention in increasing: (a) pharmacy based naloxone distribution rates, naloxone-related patient engagement, and pharmacist and technicians' attitudes, knowledge, perceived behavioral control and self-efficacy toward naloxone; and (b) pharmacy nonprescription syringe sales, and pharmacist and technicians' attitudes, knowledge, perceived behavioral control and self-efficacy toward dispensing buprenorphine for opioid use disorder (secondary outcomes). This commentary provides a brief narrative about the study and presents insights on the design and adaptations to our study protocol, including those adopted during the unprecedented COVID-19 pandemic further compounded by Western wildfires in 2020.

Flexible Buprenorphine/Naloxone Model of Care for Reducing Opioid Use in Individuals With Prescription-Type Opioid Use Disorder: An Open-Label, Pragmatic, Noninferiority Randomized Controlled Trial.
    The American journal of psychiatry, 2022, Volume: 179, Issue:10

    Extensive exposure to prescription-type opioids has resulted in major harm worldwide, calling for better-adapted approaches to opioid agonist therapy. The authors aimed to determine whether flexible take-home buprenorphine/naloxone is as effective as supervised methadone in reducing opioid use in prescription-type opioid consumers with opioid use disorder.. This seven-site, pan-Canadian, 24-week, pragmatic, open-label, noninferiority, two-arm parallel randomized controlled trial involved treatment-seeking adults with prescription-type opioid use disorder. Participants were randomized in a 1:1 ratio to treatment with sublingual buprenorphine/naloxone (target dosage, 8 mg/2 mg to 24 mg/6 mg per day; flexible take-home dosing) or oral methadone (≈60-120 mg/day; closely supervised). The primary outcome was the proportion of opioid-free urine drug screens over 24 weeks (noninferiority margin, 15%). All randomized participants were analyzed, excluding one who died shortly after randomization, for the primary analysis (modified intention-to-treat analysis).. Of 272 participants recruited (mean age, 39 years [SD=11]; 34.2% female), 138 were randomized to buprenorphine/naloxone and 134 to methadone. The mean proportion of opioid-free urine drug screens was 24.0% (SD=34.4) in the buprenorphine/naloxone group and 18.5% (SD=30.5) in the methadone group, with a 5.6% adjusted mean difference (95% CI=-0.3, +∞). Participants in the buprenorphine/naloxone group had 0.47 times the odds (95% CI=0.24, 0.90) of being retained in the assigned treatment compared with those in the methadone group. Overall, 24 drug-related adverse events were reported (12 in the buprenorphine/naloxone group [N=8/138; 5.7%] and 12 in the methadone group [N=12/134; 9.0%]) and mostly included withdrawal, hypogonadism, and overdose.. The buprenorphine/naloxone flexible model of care was safe and noninferior to methadone in reducing opioid use among people with prescription-type opioid use disorder. This flexibility could help expand access to opioid agonist therapy and reduce harms in the context of the opioid overdose crisis.

Predictors of opioid overdose during the COVID-19 pandemic: The role of relapse, treatment access and nonprescribed buprenorphine/naloxone.
    Journal of substance use and addiction treatment, 2023, Volume: 149

    Emerging data indicate a disproportionate increase in overdose deaths since the onset of COVID-19. Speculation about causes for the increase center on rising drug use, illicit drug supply changes, and reduced treatment access. Possible overdose mitigation factors include reduced federal MOUD prescribing restrictions, naloxone distribution programs, and increased use of telehealth. Similarly, nonprescribed buprenorphine (NPB) use, increasingly described as a harm reduction strategy in the absence of treatment, may have moderated overdose risk. This study explored factors associated with pandemic-related overdose in people who use opioids (PWUO) in New Jersey.. We surveyed 342 PWUO from March to May 2021. Approximately 50 % of our sample was treated at some time since the COVID-19 emergency declaration in March 2020. The risk and protective factors associated with overdose were identified using Pearson's chi square test and ANOVA and tested in a series of multivariable logistic regression models for the full sample and the subsample of PWUO treated during the pandemic.. Forty-eight percent of respondents increased their drug use during the pandemic, including 32 % who relapsed after previous abstinence. Fifteen percent overdosed at least once since March 2020. In the full sample, overdose was associated with Hispanic ethnicity (AOR = 3.51; 95 % CI = 1.22-10.11), pre-pandemic overdose (AOR = 6.75; 95 % CI = 3.03-15.02), lack/loss of medical insurance (AOR = 3.02; 95 % CI = 1.01-9.02), relapse (AOR = 2.94; 95 % CI = 1.36-6.36), and nonprescribed use of buprenorphine/naloxone (AOR = 3.16; 95 % CI = 1.49-6.70). The study found similar trends in the treatment sample, with the exceptions that heroin/fentanyl use also predicted overdose (AOR = 3.43; 95 % CI = 1.20-9.78) and the association of overdose with nonprescribed buprenorphine/naloxone was stronger (AOR = 4.91; 95 % CI = 2.01-12.03). Potential mitigating factors, such as take-home methadone and telehealth, were not significant.. Relapse during the pandemic was widespread and a significant contributor to overdose. Lack/loss of medical insurance further exacerbated the risk. Despite the growing literature reporting "therapeutic" use of NPB, people using nonprescribed buprenorphine/naloxone in the current study experienced up to five times the risk of overdose as nonusers. This finding suggests that, despite therapeutic intent, PWUO may be using NPB in ways that are ineffectual for addiction management, especially in the context of changing buprenorphine induction protocols in the context of fentanyl.

Disparities in Emergency Department Naloxone and Buprenorphine Initiation.
    The western journal of emergency medicine, 2023, Jun-30, Volume: 24, Issue:4

    Prescribing of buprenorphine and naloxone in the emergency department (ED) has been shown to be an effective intervention. The purpose of this study was to determine the frequency of prescribing of naloxone and buprenorphine and the sub-groups that may be more or less likely to receive treatment.. We used a national electronic health record database to identify patients with opioid poisoning or overdose presenting between January 2019-December 2021. Patients who were prescribed naloxone or buprenorphine were identified in this dataset and then further segmented based on self-identified gender, age, racial and ethnic identity, income categories, and social vulnerability index in order to identify sub-groups that may be less likely to be prescribed treatment.. We found 74,004 patients in the database whom we identified as presenting to the ED with an opioid poisoning or overdose. Overall, 22.8% were discharged with a prescription for naloxone, while 0.9% of patients were discharged with buprenorphine products. Patients were less likely to receive naloxone prescriptions if they were female, White or Pacific Islander, non-Hispanic, not between the ages of 18-65, and non-English speaking. We found the same pattern for buprenorphine prescriptions except that the results were not significant for ethnicity and English-speaking.. Despite evidence supporting its use, buprenorphine is not prescribed from the ED in a substantial proportion of patients. Naloxone is prescribed to a higher percentage, although still a minority of patients receive it. Some sub-groups are disadvantaged in the prescribing of these products. Further study may assist in improving the prescribing of these therapies.

A mobile addiction service for community-based overdose prevention.
    Frontiers in public health, 2023, Volume: 11

    Mainstays of opioid overdose prevention include medications for opioid use disorder (e.g., methadone or buprenorphine) and naloxone distribution. Inadequate access to buprenorphine limits its uptake, especially in communities of color, and people with opioid use disorders encounter multiple barriers to obtaining necessary medications including insurance, transportation, and consistent availability of telephones. UMass Memorial Medical Center and our community partners sought to alleviate these barriers to treatment through the deployment of a mobile addiction service, called the Road to Care. Using this approach, multidisciplinary and interprofessional providers deliver holistic addiction care by centering our patients' needs with respect to scheduling, location, and convenience. This program also extends access to buprenorphine and naloxone among people experiencing homelessness. Additional systemic and individualized barriers encountered are identified, as well as potential solutions for future mobile addiction service utilization. Over a two-year period, we have cared for 1,121 individuals who have accessed our mobile addiction service in over 4,567 encounters. We prescribed buprenorphine/naloxone (Suboxone®) to 330 individuals (29.4% of all patients). We have distributed nearly 250 naloxone kits directly on-site or and more than 300 kits via prescriptions to local pharmacies. To date, 74 naloxone rescue attempts have been reported back to us. We have demonstrated that a community-based mobile addiction service, anchored within a major medical center, can provide high-volume and high-quality overdose prevention services that facilitate engagement with additional treatment. Our experience is described as a case study below.

Duration of use and outcomes among people with opioid use disorder initiating methadone and buprenorphine in Ontario: a population-based propensity-score matched cohort study.
    Addiction (Abingdon, England), 2022, Volume: 117, Issue:7

    To characterize comparative risks and benefits of methadone versus buprenorphine/naloxone in a contemporary cohort where the unregulated drug supply is dominated by fentanyl.. Population-based propensity-score matched cohort study conducted in Ontario, Canada among people aged 18+ initiating opioid agonist therapy (OAT) for an opioid use disorder between October 2016 and December 2018 (n = 18 880).. Initiation of methadone versus buprenorphine/naloxone.. The primary outcome was opioid overdose (fatal and non-fatal) while on treatment, with secondary outcomes including opioid overdose (first 30 days of treatment), treatment discontinuation, health-care interactions related to treatment of opioid use disorder, receiving a weekly supply of take-home doses and opioid overdose within 30 days of treatment discontinuation. Outcomes were assessed over 1 year.. Overall, 7517 people initiating buprenorphine were matched to an equal number of methadone-treated individuals. Risk of opioid overdose while on treatment [hazard ratio (HR) = 0.50; 95% confidence interval (CI) = 0.37-0.68] or within the first 30 days of treatment (HR = 0.51, 95% CI = 0.31-0.85) was lower among buprenorphine recipients compared to methadone recipients. In secondary analyses, people initiating buprenorphine had a higher risk of treatment discontinuation within the first year (median time to discontinuation 104 versus 265 days, HR = 1.43, 95% CI = 1.37-1.49), had lower rates of health-care interactions for OUD (186.4 versus 254.3 per person-year; rate ratio = 0.73; 95% CI = 0.72-0.75), and a higher rate of receiving weekly take-home doses (HR = 2.33; 95% CI = 2.20-2.46). Overdose rates in the period following OAT discontinuation were higher than those observed while on treatment, but did not differ significantly by OAT type.. Although treatment retention is higher among methadone recipients, overdose risk is also elevated compared to buprenorphine recipients. These findings demonstrate the benefits of any OAT on avoidance of overdose, particularly following treatment discontinuation and with the increasingly unpredictable drug supply in North America.

Modeling the cost-effectiveness and impact on fatal overdose and initiation of buprenorphine-naloxone treatment at syringe service programs.
    Addiction (Abingdon, England), 2022, Volume: 117, Issue:10

    To estimate the number of treatment initiations, averted fatal opioid overdoses and the cost-effectiveness associated with offering buprenorphine-naloxone (buprenorphine) treatment on-site within existing syringe service programs (SSPs) in Massachusetts, USA.. This was a cohort-based mathematical model and cost-effectiveness analysis. We derived model inputs from state and national surveillance data, clinical trials and observational cohort studies. We compared an intervention scenario where 30% of SSP clients initiated buprenorphine treatment on-site at least once annually to a status quo scenario where no buprenorphine was available on-site among community treatment providers in Massachusetts, 2020-30. In individuals with opioid use disorder (OUD) we assumed that 80% of SSP clients had recently injected drugs and that treatment within SSPs would have similar or improved retention compared with standard-of-care buprenorphine programs, but higher rates of active opioid use while in treatment.. Number of treatment initiations (i.e. individuals began treatment on a medication for opioid use disorder or entered medically managed withdrawal), averted fatal opioid overdoses, quality-adjusted life-years (QALYs) and life-time discounted costs from a health sector and a limited societal perspective.. The status quo scenario resulted in 23 051 fatal overdoses and 1 511 613 treatment initiations over a 10-year simulation period. An intervention scenario with on-site SSP buprenorphine treatment averted 4797 (-20.8%) fatal opioid overdoses and resulted in 129 359 (+8.6%) additional treatment initiations compared with the status quo. The intervention scenario was the dominating scenario: providing OUD treatment through Massachusetts SSPs cost less (-$3612 per person) with patients accumulating more QALYs (0.2 per person) compared with the status quo scenario.. Offering buprenorphine treatment on-site within syringe service programs has the potential to decrease fatal overdoses substantially, improve treatment engagement and save on costs.

Availability of buprenorphine/naloxone films and naloxone nasal spray in community pharmacies in 11 U.S. states.
    Drug and alcohol dependence, 2022, 08-01, Volume: 237

    Prompt access to prescribed buprenorphine/naloxone films (BUP/NX) and naloxone nasal spray (NNS) is vital for patients with opioid use disorder (OUD), but multiple studies have documented pharmacy-level barriers.. A cross-sectional secret shopper telephone audit was conducted in a sample of 5734 actively licensed pharmacies in 11 U.S. states from May 2020-April 2021. Primary outcomes included availability of 14 generic BUP/NX 8/2 mg and one unit of NNS 4 mg. Outcomes were compared by pharmacy type, county metropolitan status, state Medicaid expansion status, and state drug overdose death rate.. Data from 4984 pharmacies (3402 chain and 1582 independent) were analyzed. Both medications were available in 41.2 % of pharmacies, BUP/NX was available in 48.3%, and NNS was available in 69.5%. Chain pharmacies were significantly more likely than independent pharmacies to have both medications available, to have each medication available individually, and to be willing to order BUP/NX. Pharmacies in metropolitan counties were more likely to have BUP/NX available than pharmacies in non-metropolitan counties, pharmacies in Medicaid expansion states were more likely to have both medications available and to have NNS available than pharmacies in non-expansion states, and pharmacies in states with high drug overdose death rates were more likely to have NNS available than pharmacies in states with low drug overdose death rates.. BUP/NX and NNS are not readily accessible in many U.S. pharmacies. Deficits in access are most pronounced in independent pharmacies, though county- and state-level factors may also influence availability of these essential medications.

Engagement in drug treatment following nonfatal overdose among people who inject drugs in Appalachia.
    The International journal on drug policy, 2021, Volume: 93

    Immediately after experiencing a non-fatal overdose, many people who inject drugs (PWID) engage in harm-minimizing behavior change, including engagement in drug treatment. To inform the implementation of tailored interventions designed to facilitate drug treatment engagement in rural communities, we sought to identify correlates of starting any form of drug treatment after their most recent overdose among PWID who reside in a rural county in West Virginia.. Data are from a PWID population estimation study in Cabell County, West Virginia. We used multivariable logistic regression to identify independent sociodemographic and substance use-related correlates of any form of drug treatment engagement after an overdose among 179 PWID who had overdosed in the past 6 months.. One-third of our sample (33.0%) started any form of drug treatment in the 30 days following their most recent overdose. Factors associated with engaging in drug treatment included: recent buprenorphine or Suboxone injection (aOR: 2.39, 95% CI: 1.15, 4.96), someone calling 911 after their most recent overdose (aOR: 3.29, 95% CI: 1.63, 6.65), and older age (aOR per year of age: 0.95, 95% CI: 0.91, 0.99).. Our results suggest that contact with emergency personnel after an overdose may represent an important opportunity to link PWID to drug treatment. The implementation of response teams trained in linking PWID to the services they require and helping persons navigate treatment systems maybe be a valuable intervention to reduce the harms of the opioid overdose crisis.

Unit-Dose Packaging and Unintentional Buprenorphine-Naloxone Exposures.
    Pediatrics, 2018, Volume: 141, Issue:6

    Buprenorphine accounts for the most opioid-related pediatric hospital admissions when compared with other opioid analgesics. Since 2010, several manufacturers began distributing their buprenorphine products with unit-dose packaging (UDP). Our main objective in this study is to evaluate the impact of UDP on unintentional pediatric buprenorphine-naloxone poison center exposures.. This is an observational surveillance study in which the Researched Abuse, Diversion, and Addiction-Related Surveillance System Poison Center Program is used. The main outcome was cases of unintentional ingestions involving children <6 years old and buprenorphine-naloxone (combination) products. The study was split into 3 periods: pre-UDP (first quarter 2008 through fourth quarter 2010), transition to UDP (first quarter 2011 through fourth quarter 2012), and post-UDP (first quarter 2013 through fourth quarter 2016).. Overall, there were 6217 exposures to combination products. In the pre-UDP period, there were 20.57 pediatric unintentional exposures per 100 000 prescriptions dispensed; in the transition to UDP period, there were 8.77 pediatric unintentional exposures per 100 000 prescriptions dispensed; and in the post-UDP period, there were 4.36 pediatric unintentional exposures per 100 000 prescriptions dispensed. This represents a 78.8% (95% confidence interval: 76.1%-81.3%;. The shift from non-UDP to UDP in over 80% of buprenorphine-naloxone products was associated with a significant decrease in unintentional pediatric exposures reported to poison centers. Packaging controls should be a mainstay in the approach to the prevention of unintentional buprenorphine pediatric exposures as well as exposures to other prescription opioids.

Utilization of opioid agonist therapy among incarcerated persons with opioid use disorder in Vancouver, Canada.
    Drug and alcohol dependence, 2018, 12-01, Volume: 193

    Inability to access opioid agonist therapy (OAT) in correctional settings has previously been reported in Vancouver, Canada, and is associated with harms among people with opioid use disorder (OUD), including overdose death. We investigated the prevalence and correlates of OAT utilization within correctional settings among incarcerated persons with OUD in Vancouver.. Data were derived from three prospective cohorts of people who use drugs in Vancouver between 2005 and 2016. Using multivariable generalized estimating equations, we examined factors associated with OAT utilization among participants with OUD reporting incarceration in the past six months.. Among 597 eligible participants, 207 (34.7%) contributed 325 reports of having utilized OAT while incarcerated. Of those, 295 (90.8%) were continuations and 30 (9.2%) were new initiations of OAT while incarcerated. For those currently on OAT (at the time of interview), in multivariable analyses, non-fatal overdose (adjusted odds ratio [AOR] = 0.49, 95% confidence interval [CI]: 0.29-0.82) and daily prescription opioid use (AOR = 0.42, 95% CI: 0.20-0.85) remained independently and negatively associated with having utilized OAT while incarcerated. For those not currently on OAT, none of the variables considered had significant associations with utilization of OAT while incarcerated.. Utilization of OAT in correctional settings was low in our sample. Utilization of OAT was significantly and negatively associated with overdose and ongoing prescription opioid misuse if OAT was continued upon release from correctional settings. Findings underscore the urgent need for improved utilization of OAT in correctional settings, and linkage to community care to prevent harms such as overdose.

Exposure to fentanyl-contaminated heroin and overdose risk among illicit opioid users in Rhode Island: A mixed methods study.
    The International journal on drug policy, 2017, Volume: 46

    Illicit fentanyl use has become wide spread in the US, causing high rates of overdose deaths among people who use drugs. This study describes patterns and perceptions of fentanyl exposure among opioid users in Rhode Island.. A mixed methods study was conducted via questionnaire with a convenience sample of 149 individuals using illicit opioids or misusing prescription opioids in Rhode Island between January and November 2016. Of these, 121 knew of fentanyl and reported known or suspected exposure to fentanyl in the past year. Semi-structured interviews were conducted with the first 47 participants.. Study participants were predominantly male (64%) and white (61%). Demographic variables were similar across sample strata. Heroin was the most frequently reported drug of choice (72%). Self-reported exposure to illicit fentanyl in the past year was common (50.4%, n=61). In multivariate models, regular (at least weekly) heroin use was independently associated with known or suspected fentanyl exposure in the past year (adjusted prevalence ratio (APR)=4.07, 95% CI: 1.24-13.3, p=0.020). In interviews, users described fentanyl as unpleasant, potentially deadly, and to be avoided. Participants reporting fentanyl exposure routinely experienced or encountered non-fatal overdose. Heroin users reported limited ability to identify fentanyl in their drugs. Harm reduction strategies used to protect themselves from fentanyl exposure and overdose, included test hits, seeking prescription opioids in lieu of heroin, and seeking treatment with combination buprenorphine/naloxone. Participants were often unsuccessful in accessing structured treatment programs.. Among illicit opioid users in Rhode Island, known or suspected fentanyl exposure is common, yet demand for fentanyl is low. Fentanyl-contaminated drugs are generating user interest in effective risk mitigation strategies, including treatment. Responses to the fentanyl epidemic should be informed by the perceptions and experiences of local users. The rapid scale-up of buprenorphine/naloxone provision may slow the rate of fentanyl-involved overdose deaths.

Rationale for cannabis-based interventions in the opioid overdose crisis.
    Harm reduction journal, 2017, 08-18, Volume: 14, Issue:1

    North America is currently in the grips of a crisis rooted in the use of licit and illicit opioid-based analgesics. Drug overdose is the leading cause of accidental death in Canada and the US, and the growing toll of opioid-related morbidity and mortality requires a diversity of novel therapeutic and harm reduction-based interventions. Research suggests that increasing adult access to both medical and recreational cannabis has significant positive impacts on public health and safety as a result of substitution effect. Observational and epidemiological studies have found that medical cannabis programs are associated with a reduction in the use of opioids and associated morbidity and mortality.. This paper presents an evidence-based rationale for cannabis-based interventions in the opioid overdose crisis informed by research on substitution effect, proposing three important windows of opportunity for cannabis for therapeutic purposes (CTP) to play a role in reducing opioid use and interrupting the cycle towards opioid use disorder: 1) prior to opioid introduction in the treatment of chronic pain; 2) as an opioid reduction strategy for those patients already using opioids; and 3) as an adjunct therapy to methadone or suboxone treatment in order to increase treatment success rates. The commentary explores potential obstacles and limitations to these proposed interventions, and as well as strategies to monitor their impact on public health and safety.. The growing body of research supporting the medical use of cannabis as an adjunct or substitute for opioids creates an evidence-based rationale for governments, health care providers, and academic researchers to consider the implementation and assessment of cannabis-based interventions in the opioid crisis.

Differences in polysubstance use patterns and drug-related outcomes between people who inject drugs receiving and not receiving opioid substitution therapies.
    Addiction (Abingdon, England), 2016, Volume: 111, Issue:7

    To test if polysubstance use profiles and drug-related outcomes differ between those receiving and not receiving opioid substitution therapies (OST) among people who inject drugs (PWID).. An annual cross-sectional, sentinel sample of PWID across Australia.. Data came from 3 years (2011-13) of the Illicit Drug Reporting System (IDRS).. A total of 2673 participants who injected drugs from the combined national IDRS samples of 2011 (n = 868), 2012 (n = 922) and 2013 (n = 883).. Latent class analysis (LCA) was used to summarize participants' self-reported use of 18 types of substances, with the resulting polysubstance use profiles then associated with participant experience of a number of drug-related outcomes.. Polysubstance use profiles exhibiting a broad range of substance use were generally at increased risk of negative drug-related outcomes, whether or not participants were receiving OST, including thrombosis among OST receivers [odds ratio (OR) = 2.13, 95% confidence intervals (CI) = 1.09-4.17], injecting with used needles among OST receivers and non-receivers, respectively (OR = 2.78, 95% CI = 1.50-5.13; OR = 2.15, 95% CI = 1.34-3.45) and violent criminal offences among OST receivers and non-receivers, respectively (OR =2.30, 95% CI = 1.16-4.58; OR = 1.87, 95% CI = 1.14-3.07). An important exception was non-fatal overdose which was related specifically to a class of PWID who were not receiving OST and used morphine frequently (OR = 1.83, 95% CI = 1.06-3.17) CONCLUSION: Regardless of opioid substitution therapies usage, people who inject drugs who use a broad-range of substances experience greater levels of injecting-related injuries and poorer health outcomes and are more likely to engage in criminal activity than other groups of people who inject drugs.

Reversal of overdose on fentanyl being illicitly sold as heroin with naloxone nasal spray: A case report.
    The American journal on addictions, 2015, Volume: 24, Issue:5

    This is a case report describing a reversal of fentanyl overdose with naloxone nasal spray. The patient was not aware that he overdosed on fentanyl being sold as heroin.. The Veterans Health Administration (VHA) has implemented an initiative to provide education for veterans, their families, friends and significant others about opioid overdose and use of naloxone reversal kits. The Atlanta VA Medical Center adopted this program to reduce the risk of opioid overdose in high risk patients.. Over the past year, we provided educational sessions for 63 veterans and their families. We also prescribed 41 naloxone kits. We have received three reports of opioid overdose reversal with use of naloxone kits prescribed by the Atlanta VA Medical Center.. The authors recommend that public health administrators and policy makers advocate for the implementation of these programs to reduce the rising number of overdose death in the United States and worldwide.

A Question About the Safety of Buprenorphine/Naloxone and Benzodiazepine Drugs.
    Journal of psychosocial nursing and mental health services, 2015, Volume: 53, Issue:12

    Drug overdose is the leading cause of injury death in the United States, and most deaths are related to prescription drugs. A substantial proportion of these deaths involve opioid or benzodiazepine drugs, and many overdoses include a combination of both drug classes. Buprenorphine/naloxone has an unusual pharmacology that distinguishes it from other opioid drugs. Animal and human studies have found that buprenorphine is associated with a ceiling to its cardio-respiratory depressant effect at higher doses, such that it may have a wider safety margin compared to other opioid drugs. Compared to buprenorphine alone, buprenorphine/naloxone is associated with less cardiorespiratory depression. Drug safety data from the National Poison Data System, Drug Abuse Warning Network, and other sources suggest that the safety of buprenorphine/naloxone is favorable compared to the morbidity and mortality associated with other opioid drugs and other classes of psychotropic drugs.

A case of heroin overdose reversed by sublingually administered buprenorphine/naloxone (Suboxone).
    Addiction (Abingdon, England), 2008, Volume: 103, Issue:7

    Opioid overdose is a major source of morbidity and mortality in injection drug users in the United States and many other countries.. A case is described in which buprenorphine/naloxone (Suboxone) was administered sublingually to reverse a heroin overdose.. Sublingually administered buprenorphine/naloxone might be used as a means to reverse opioid overdose.
