Buprenorphine

Oxidative stress (OS) is caused by an imbalance between the production of oxygen-containing free radicals and their elimination. General anesthesia increases the production of reactive oxygen species (ROS) and therefore causes oxidative stress. Our objective was to determine the effects of medetomidine-butorphanol (MEDBUT) and medetomidine-buprenorphine (MEDBUP) on oxidative stress and cardiorespiratory parameters in dogs undergoing ovariohysterectomy (OHE). Ten healthy female dogs were randomly assigned to two groups: the MEDBUT group ( n = 5) received medetomidine and butorphanol, while the MEDBUP group ( n = 5) received medetomidine and buprenorphine...

INTRODUCTION: France is a leading country for opioid agonist treatment providing, with a predominance of buprenorphine. General practitioners (GPs) are the main prescribers of buprenorphine, but they seem to be less involved over the last 10 years. This work is the second part of a larger study analysing buprenorphine prescribing among French GPs working in primary care, and aims to describe GPs' practices when prescribing buprenorphine. METHODS: This is a cross-sectional study conducted in France from March to July 2021 among a sample of GPs in the Sentinelles network, a national epidemiologic surveillance system...

The management of cancer-related pain in patients with opioid use disorder (OUD) remains complex and often challenging for clinicians and patients. There is currently a paucity of data to guide best practices, and the evidence that exists is variably applied. In this hospital-based questionnaire, we sought to understand the variation in practice patterns among clinicians in palliative medicine, addiction medicine, and hospital medicine, in caring for this complex patient population. Sixty-two questionnaire responses were analyzed and variation was found in management of pain, as well as initiation or titration of buprenorphine and methadone...

PURPOSE OF REVIEW: Collaborative models of care where pharmacists work alongside physicians have been developed for a range of physical health conditions, with benefits including improved patient outcomes and increased access to ongoing care. Opioid agonist treatment (methadone and buprenorphine) is a clinically effective and cost-effective treatment for opioid use disorder that is under-utilized in many countries due to a shortage of prescribers. In recent years, there has been increased interest in the development of collaborative models that utilize pharmacists to overcome barriers to treatment...

This scoping review summarized the literature regarding naloxone distribution from emergency departments (EDs) without a prescription. Our intention was to examine various naloxone distribution programs, their methodologies, and the level of effectiveness of each. Understanding these key aspects of naloxone distribution could lead to improved standardized protocols, saving countless additional lives from opioid overdose. This review evaluated studies reporting naloxone distribution from EDs in the United States...

Extended-release formulations of buprenorphine offer less frequent dosing, provide consistent medication delivery, and improve adherence for treatment of opioid use disorder (OUD). Although buprenorphine is a partial agonist with seemingly less precipitated withdrawal and easier initiation than full opioid agonists used for OUD, its use is not benign and understanding of the different extended-release formulations is necessary. We report a case of a patient that received a long-acting buprenorphine formulation (Sublocade®) administered subcutaneously that presented to the emergency department with tachycardia, hyperglycemia, elevated anion gap, and sustained nausea and vomiting refractory to pharmacotherapy requiring surgical removal of the buprenorphine depot for resolution of nausea and vomiting symptoms...

Substantial percentages of persons receiving medications for opioid use disorder (MOUD) continue to experience clinically significant levels of pain and opioid withdrawal, which may pose barriers to reducing opioid use. Continued pain, in particular, may increase the risk for psychiatric problems and poorer treatment retention, especially with a lack of adequate care for pain. The goals of these analyses were to characterize the prevalence of, and patient-level variables associated with, pain and opioid withdrawal, as well as utilization of related coping strategies and treatments...

Loperamide is an over-the-counter peripheral mu-opioid agonist commonly used to manage diarrhoea. When taken in an excessive dose, loperamide's penetration of the central nervous system increases, leading to euphoria, respiratory depression and other opioid effects. A health warning was released in the United States in 2016 with increased reports of excessive loperamide use leading to cardiac conduction abnormalities such as ventricular tachycardia, prolonged QTc and Torsades des Pointes. The growing number of cases is likely due to the increased restrictions on other opioids...

INTRODUCTION: There has been a significant increase in methamphetamine/amphetamine use in North America, particularly among people who use opioids. Despite its association with several negative health consequences, the population of people who use methamphetamine/amphetamine with opioids is not well characterised. The aim of this study was to investigate correlates of methamphetamine/amphetamine use among adults with prescription-type opioid use disorder (POUD) starting methadone or buprenorphine/naloxone as part of a pragmatic randomised treatment trial in Canada...

IMPORTANCE: Injectable extended-release (XR)-naltrexone is an effective treatment option for opioid use disorder (OUD), but the need to withdraw patients from opioid treatment prior to initiation is a barrier to implementation. OBJECTIVE: To compare the effectiveness of the standard procedure (SP) with the rapid procedure (RP) for XR-naltrexone initiation. DESIGN, SETTING, AND PARTICIPANTS: The Surmounting Withdrawal to Initiate Fast Treatment with Naltrexone study was an optimized stepped-wedge cluster randomized trial conducted at 6 community-based inpatient addiction treatment units...

BACKGROUND: Physical or mental health comorbidities are common among people with substance use disorders undergoing opioid agonist therapy. As both a preventive and treatment strategy, exercise offers various health benefits for several conditions. Exercise interventions to people with substance use disorders receiving opioid agonist therapy are limited. This study aims to explore experiences with physical activity, perceived barriers, and facilitators among people receiving opioid agonist therapy...

PURPOSE: We utilized quality improvement (QI) approaches to increase emergency department (ED) provider engagement with research participant enrollment during the opioid crisis and coronavirus disease (COVID-19) pandemic. The context of this work is the Evaluating Microdosing in the Emergency Department (EMED) study, a randomized trial offering buprenorphine/naloxone to ED patients through randomization to standard or microdosing induction. Engaging providers is crucial for participant recruitment to our study...

INTRODUCTION: Medications for opioid use disorder (MOUD) including methadone (MMT), buprenorphine (BUP), and naltrexone (NTX) are safe and effective. However, there are significant negative perceptions surrounding MOUD, creating barriers to uptake. While research on MOUD stigma has largely focused on provider and patient experiences, fewer studies have explored MOUD perceptions among the general public. Given that MOUD stigma expressed by social ties surrounding individuals with OUD can influence treatment choices, we assessed MOUD perceptions among U...

INTRODUCTION: Extended-release buprenorphine (XR-Bup) is associated with reduced opioid use and opioid negative urine drug screens. Little is known about its use in outpatient addiction care provided within health systems. METHODS: Individuals prescribed XR-Bup were identified from electronic health records; chart abstraction was conducted. Primary outcome was all-cause emergency department (ED) use. Secondary outcomes included ED use or inpatient stays for mental health or substance use, ED use for any other cause, discontinuation reasons, and drug substitution...

Objectives. To evaluate changes in monthly buprenorphine dispensation associated with federal prescribing policies in Washington State from 2012 to 2022. Methods. We conducted an interrupted time series analysis comparing monthly buprenorphine prescriptions dispensed per 1000 population after the Comprehensive Addiction and Recovery Act (CARA), Substance Use-Disorder Prevention That Promotes Opioid Recovery and Treatment for Patients and Communities Act (SUPPORT), and new prescribing rules during the COVID-19 pandemic...

INTRODUCTION: The health and economic consequences of inadequately treated opioid use disorder (OUD) are substantial. Healthcare systems in the United States (US) and other countries are facing a growing healthcare crisis due to opioids. Although effective medications for OUD exist, relying solely on clinical information is insufficient for addressing the opioid crisis. AREAS COVERED: In this review, the role of pharmacoeconomic studies in informing evidence-based medication treatment for OUD is discussed, with a particular emphasis on the US healthcare system, where the economic burden is significantly higher than the global average...

Drug overdose is a leading cause of maternal mortality. Psychiatrists can play a critical role in reducing these deaths by delivering effective evidence-based treatments for perinatal opioid use disorder (POUD), including the use of buprenorphine. Medications for POUD (i.e., buprenorphine, methadone) are life-saving treatments, but only half of those who are diagnosed as having POUD will receive this treatment, which can result in an increased risk for return to opioid use, overdose, and death. Psychiatrists are well positioned to prescribe buprenorphine given the Drug Enforcement Administration's (DEA) removal of the requirement to submit a Notice of Intent to prescribe buprenorphine for the treatment of opioid use disorders...

BACKGROUND: Zoledronate, a bisphosphonate, is a potent first-line treatment for osteoporosis. It is also a preferred treatment for hypercalcemia especially when unresponsive to intravenous fluids. Bisphosphonates can cause acute phase reactions that mimic opioid withdrawal symptoms, which can confound provider decision-making. Our case highlights cognitive bias involving a patient with opioid use disorder who received zoledronate for hypercalcemia secondary to immobilization and significant bone infection...
