Buprenorphine fentanyl

IMPORTANCE: Although substantial evidence supports buprenorphine for treatment of opioid use disorder (OUD) in controlled trials, prospective study of patient outcomes in clinical implementation of emergency department (ED) buprenorphine treatment is lacking. OBJECTIVE: To examine the association between buprenorphine treatment in the ED and follow-up engagement in OUD treatment 1 month later. DESIGN, SETTING, AND PARTICIPANTS: This multisite cohort study was conducted in 7 California EDs participating in a statewide implementation project to improve access to buprenorphine treatment...

North America is facing an unprecedented public health emergency of opioid-related morbidity and mortality. The mortality benefits of oral medication treatment for opioid use disorder (MOUD), such as methadone or buprenorphine, are well documented. However, barriers to access and long-term engagement have prevented maximizing their benefits. Long-acting injectable buprenorphine formulations were developed to address some of the challenges associated with oral MOUD. The "Pilot study to assess the feasibility, efficacy, and safety of extended-release injectable buprenorphine for the treatment of opioid use disorder among individuals at high risk of overdose" (FASTER-BUP) was developed to explore this treatment option in populations at high risk of overdose in a real-world Canadian setting...

PURPOSE OF REVIEW: Opioid use disorder (OUD) in pregnancy has significantly in the last decade, impacting 8.2 per 1000 deliveries. OUD carries significant risk of morbidity and mortality for both the birthing person and neonate, but outcomes for both are improved with opioid agonist treatment (OAT). Here, we describe the recommended forms of OAT in pregnancy, updates to the literature, and alternate OAT strategies, and share practical peripartum considerations for patients on OAT. RECENT FINDINGS: Recent studies comparing buprenorphine and methadone have reaffirmed previous findings that buprenorphine is associated with superior outcomes for the neonate, without clear differences in morbidity or mortality for the birthing person...

The 2000-2001 and the 2022-2023 Taliban opium bans were and could be two of the largest ever disruptions to a major illegal drug market. To help understand potential implications of the current ban for Europe, this paper analyzes how opioid markets in seven Baltic and Nordic countries responded to the earlier ban, using literature review, key informant interviews, and secondary data analysis. The seven nations' markets responded in diverse ways, including rebounding with the same drug (heroin in Norway), substitution to a more potent opioid (fentanyl replacing heroin in Estonia), and substitution to one with lower risk of overdose (buprenorphine replacing heroin in Finland)...

The opioid epidemic has become a serious national crisis in the United States. An indepth systematic analysis of opioid-related adverse events (AEs) can clarify the risks presented by opioid exposure, as well as the individual risk profiles of specific opioid drugs and the potential relationships among the opioids. In this study, 92 opioids were identified from the list of all Food and Drug Administration (FDA)-approved drugs, annotated by RxNorm and were classified into 13 opioid groups: buprenorphine, codeine, dihydrocodeine, fentanyl, hydrocodone, hydromorphone, meperidine, methadone, morphine, oxycodone, oxymorphone, tapentadol, and tramadol...

Current research indicates that tapering opioids may improve pain and function in patients with chronic noncancer pain. However, gaps in the literature remain regarding the choice of opioid and nonopioid interventions to support a successful taper. This study used an Australian primary care data set to identify a cohort of patients on long-term opioid therapy commencing opioid taper between January 2016 and September 2019. Using logistic regression analysis, we compared key clinical factors associated with differing taper outcomes...

Opioids refer to chemicals that agonize opioid receptors in the body resulting in analgesia and sometimes, euphoria. Opiates include morphine and codeine; semi-synthetic opioids include heroin, hydrocodone, oxycodone, and buprenorphine; and fully synthetic opioids include tramadol, fentanyl and methadone. In 2021, an estimated 5.6 million individuals met criteria for opioid use disorder. This article provides an overview of the pharmacology of heroin and non-prescription fentanyl (NPF) and its synthetic analogues, and summarizes the literature related to the management of opioid use disorder, overdose, and withdrawal...

INTRODUCTION: Buprenorphine is an important therapy for opioid use disorder and may also reduce the risk of fatal overdoses in fentanyl exposures. However, the role of buprenorphine in reducing this risk has not been quantified. This cross-sectional study examined the association between buprenorphine presence, decedent characteristics, and other factors with the predicted fentanyl concentrations in overdose deaths. METHODS: The study identified unintentional fentanyl overdose decedents (n = 3036) from the West Virginia Forensic Drug Database, 2011 through mid-2020...

BACKGROUND: Carceral officials often cite diversion of medication for opioid use disorder (MOUD) (e.g., buprenorphine) as a reason for not offering MOUD treatment in jails and prisons with little understanding of patient perspectives. We aimed to understand patient perceptions of medication diversion from jail-based MOUD programs and the factors that contribute to and reduce diversion. METHODS: We conducted thematic analyses of semi-structured interviews held in 2021-22 with 38 adults who received MOUD treatment and were released from eight Massachusetts jails that had implemented a MOUD program on or after September 2019...

Buprenorphine, a partial opioid agonist, is a Food and Drug Administration-approved medication for the treatment of opioid use disorder (OUD). However, due to its high binding affinity, precipitated withdrawal may occur if initiated in the presence of other opioids. The growing literature demonstrates promise for alternative induction model of low-dose initiation of buprenorphine for the treatment of OUD, specifically targeting patients averse to withdrawal or using fentanyl. In this case series, we present four clinical cases of outpatient inductions, in which three out of four successfully transitioned from fentanyl to buprenorphine, and one patient transitioned from methadone to buprenorphine using a low-dose induction method...

BACKGROUND AND OBJECTIVES: Synthetic opioids, including fentanyl and fentanyl analogs, account for over 70,000 annual overdose deaths in the United States, but there is limited information examining methods of induction and maintenance outcomes for buprenorphine treatment of patients with opioid use disorder (OUD) using these opioids. METHODS: A secondary analysis of results grouped by fentanyl use status was completed for an open-label study with rapid induction of extended-release buprenorphine in the inpatient research unit...

BACKGROUND: Although both nonsteroidal anti-inflammatory drugs (NSAIDs) and opioids are used for analgesia in acute pancreatitis (AP), the analgesic of choice is not known. We compared buprenorphine, an opioid, and diclofenac, an NSAID, for analgesia in AP. METHODS: In a double-blind randomized controlled trial, AP patients were randomized to receive intravenous diclofenac or intravenous buprenorphine. Fentanyl was used as rescue analgesia, delivered through a patient-controlled analgesia pump...

The United States continues to be impacted by decades of an opioid misuse epidemic, worsened by the COVID-19 pandemic and by the growing prevalence of highly potent synthetic opioids (HPSO) such as fentanyl. In instances of a toxicity event, first-response administration of reversal medications such as naloxone can be insufficient to fully counteract the effects of HPSO, particularly when there is co-occurring substance use. In an effort to characterize and study this multi-faceted problem, the Camden Opioid Research Initiative (CORI) has been formed...

In the last decade, the U.S. opioid overdose crisis has magnified, particularly since the introduction of synthetic opioids, including fentanyl. Despite the benefits of medications for opioid use disorder (MOUD), only about a fifth of people with opioid use disorder (OUD) in the U.S. receive MOUD. The ubiquity of pharmacists, along with their extensive education and training, represents great potential for expansion of MOUD services, particularly in community pharmacies. The National Institute on Drug Abuse's National Drug Abuse Treatment Clinical Trials Network (NIDA CTN) convened a working group to develop a research agenda to expand OUD treatment in the community pharmacy sector to support improved access to MOUD and patient outcomes...

BACKGROUND: Because of a risk of precipitated withdrawal occurring from buprenorphine induction in people who use fentanyl, low-dose inductions are becoming increasingly common. However, little evidence exists on the use of this method in pregnant people. METHODS: We conducted a case series of all pregnant people treated for opioid use disorder with low-dose buprenorphine induction at the University of Maryland Medical Center between January 1, 2021, and August 22, 2022...

BACKGROUND: Recent policies have lessened restrictions around prescribing buprenorphine-naloxone (buprenorphine) for the treatment of opioid use disorder (OUD). The primary concern expressed by critics of these policies is the potential for buprenorphine diversion. However, the population-level effects of increased buprenorphine diversion are unclear. If replacing the use of heroin or fentanyl, use of diverted buprenorphine could be protective. METHODS: Our study aim was to estimate the impact of buprenorphine diversion on opioid overdose using an agent-based model calibrated to North Carolina...

Buprenorphine extended-release (BUP-XR) provides sustained delivery of buprenorphine to control withdrawal and craving symptoms in the form of a monthly injectable and has been shown to improve health outcomes in patients with opioid use disorder. It is recommended that patients are stabilized with a transmucosal buprenorphine product, for at least 7 days per the product monograph; however, clinically, this timeline may be expedited. We report a case of a hospitalized patient with unregulated fentanyl use who underwent a successful transdermal buprenorphine induction for 48 hours to initiate BUP-XR with minimal levels of withdrawal and without precipitating opioid withdrawal...

Opioid use disorder continues to drive overdose deaths in many countries, including the United States. Illicit fentanyl and its analogues have emerged as key contributors to the complications and mortality associated with opioid use disorder. Medications for opioid use disorder treatment, such as methadone and buprenorphine, are safe and substantially reduce opioid use, infectious complications, and mortality risk, but remain underutilized. Polysubstance use and emerging substances such as xylazine and designer benzodiazepines create additional treatment challenges...
