  • Dezocine Exhibits Antihypersensitivity Activities in Neuropathy Through
    www.nature.com/scientificreports OPEN Dezocine exhibits antihypersensitivity activities in neuropathy through spinal Received: 09 November 2016 Accepted: 19 January 2017 μ-opioid receptor activation and Published: 23 February 2017 norepinephrine reuptake inhibition Yong-Xiang Wang1, Xiao-Fang Mao1, Teng-Fei Li1, Nian Gong1 & Ma-Zhong Zhang2 Dezocine is the number one opioid painkiller prescribed and sold in China, occupying 44% of the nation’s opioid analgesics market today and far ahead of the gold-standard morphine. We discovered the mechanisms underlying dezocine antihypersensitivity activity and assessed their implications to antihypersensitivity tolerance. Dezocine, given subcutaneously in spinal nerve-ligated neuropathic rats, time- and dose-dependently produced mechanical antiallodynia and thermal antihyperalgesia, significantly increased ipsilateral spinal norepinephrine and serotonin levels, and induced less antiallodynic tolerance than morphine. Its mechanical antiallodynia was partially (40% or 60%) and completely (100%) attenuated by spinal μ-opioid receptor (MOR) antagonism or norepinephrine depletion/α2-adrenoceptor antagonism and combined antagonism of MORs and α2-adenoceptors, respectively. In contrast, antagonism of spinal κ-opioid receptors (KORs) and δ-opioid receptors (DORs) or depletion of spinal serotonin did not significantly alter dezocine antiallodynia. In addition, dezocine- delayed antiallodynic tolerance was accelerated by spinal norepinephrine depletion/α2-adenoceptor antagonism. Thus dezocine produces antihypersensitivity activity through spinal MOR activation and norepinephrine reuptake inhibition (NRI), but apparently not through spinal KOR and DOR activation, serotonin reuptake inhibition or other mechanisms. Our findings reclassify dezocine as the first analgesic of the recently proposed MOR-NRI, and reveal its potential as an alternative to as well as concurrent use with morphine in treating pain.

  • Measures and CDS for Safer Opioid Prescribing: a Literature Review
    Measures and CDS for Safer Opioid Prescribing: A Literature Review Measures and CDS for Safer Opioid Prescribing: A Literature Review Executive Summary The U.S. opioid epidemic continues to pose significant challenges for patients, families, clinicians, and public health policy. Opioids are responsible for an estimated 315,000 deaths (from 1999 to 2016) and have caused 115 deaths per day.1 In 2017, the U.S. Department of Health and Human Services declared the opioid epidemic a public health crisis.2 The total economic burden of opioid abuse in the United States has been estimated to be $78.5 billion per year.3 Although providing care for chronic opioid users is important, equally vital are efforts to prevent so-called opioid-naïve patients (patients with no history of opioid use) from developing regular opioid use, misuse, or abuse. However, much remains unclear regarding what role clinician prescribing habits play and what duration or dose of opioids may safely be prescribed without promoting long-term use.4,5 In 2013, ECRI Institute convened the Partnership for Health IT Patient Safety, and its component, single-topic-focused workgroups followed. For this subject, the Electronic Health Record Association (EHRA): Measures and Clinical Decision Support (CDS) for Safer Opioid Prescribing workgroup included members from the Healthcare Information and Management Systems Society (HIMSS) EHRA and the Partnership team. The project was oriented towards exploring methods to enable a synergistic cycle of performance measurement and identifying electronic health record (EHR)/health information technology (IT)–enabled approaches to support healthcare organizations’ ability to assess and measure opioid prescribing.

  • Opioid-Induced Inhibition of the Human 5-HT and Noradrenaline Transporters in Vitro: Link to Clinical Reports of Serotonin Syndrome
    British Journal of British Journal of Pharmacology (2018) 175 532–543 532 BJP Pharmacology RESEARCH PAPER Opioid-induced inhibition of the human 5-HT and noradrenaline transporters in vitro: link to clinical reports of serotonin syndrome Correspondence Professor Matthias E. Liechti, Division of Clinical Pharmacology and Toxicology, University Hospital Basel, Schanzenstrasse 55, Basel, CH-4056, Basel, Switzerland. E-mail: [email protected] Received 21 June 2017; Revised 3 November 2017; Accepted 8 November 2017 Anna Rickli1, Evangelia Liakoni2, Marius C Hoener3 and Matthias E Liechti1 1Clinical Pharmacology and Toxicology, Department of Biomedicine, Department of Internal Medicine, University Hospital Basel, University of Basel, Basel, Switzerland, 2Clinical Pharmacology and Toxicology, Department of General Internal Medicine, Inselspital, Bern University Hospital, Univer- sity of Bern, Bern, Switzerland, and 3Neuroscience Research, pRED, Roche Innovation Center Basel, F.Hoffmann-La Roche Ltd, Basel, Switzerland BACKGROUND AND PURPOSE Opioids may inhibit the 5-HT transporter (SERT) and the noradrenaline transporter (NET). NET inhibition may contribute to an- algesia, and SERT inhibition or interactions with 5-HT receptors may cause serotonergic toxicity. However, the effects of different opioids on the human SERT, NET and 5-HT receptors have not been sufficiently studied. EXPERIMENTAL APPROACH We determined the potencies of different opioids to inhibit the SERT and NET in vitro using human transporter-transfected fi HEK293 cells. We also tested binding af nities at 5-HT1A,5-HT2A and 5-HT2C receptors. Additionally, we assessed clinical cases of the serotonin syndrome associated with each opioid reported by PubMed and a World Health Organization database. KEY RESULTS Dextromethorphan, l(R)-methadone, racemic methadone, pethidine, tramadol and tapentadol inhibited the SERT at or close to observed drug plasma or estimated brain concentrations in patients.

    View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by PubMed Central YALE JOURNAL OF BIOLOGY AND MEDICINE 83 (2010), pp.11-25. Copyright © 2010. REVIEW Recent Advances in Postoperative Pain Management Nalini Vadivelu, MD a* ; Sukanya Mitra, MD b; and Deepak Narayan, MD c Departments of aAnesthesiology and cSurgery, Yale University School of Medicine, New Haven, Connecticut, and bDepartment of Anaesthesia & Intensive Care, Government Medical College & Hospital, Chandigarh, India Good pain control after surgery is important to prevent negative outcomes such as tachy - cardia, hypertension, myocardial ischemia, decrease in alveolar ventilation, and poor wound healing. Exacerbations of acute pain can lead to neural sensitization and release of medi - ators both peripherally and centrally. Clinical wind up occurs from the processes of N-Methyl D-Aspartate (NMDA†) activation, wind up central sensitization, long-term potentiation of pain (LTP), and transcription-dependent sensitization. Advances in the knowledge of molec - ular mechanisms have led to the development of multimodal analgesia and new pharmaceu - tical products to treat postoperative pain. The new pharmacological products to treat postoperative pain include extended-release epidural morphine and analgesic adjuvants such as capsaicin, ketamine, gabapentin, pregabalin dexmetomidine, and tapentadol. Newer postoperative patient-controlled analgesia (PCA) in modes such as intranasal, regional, transdermal, and pulmonary presents another interesting avenue of development. Proper pain relief is a major concern concerns of the surgeon because of its close and area of focus in the United States today. ties with clinical outcome and acute post - Pre-operatively, one of the most common operative patient well-being.
