Opioid-induced proinflammatory glial activation modulates wide-ranging aspects of opioid pharmacology including: opposition of acute and chronic opioid analgesia, opioid analgesic tolerance, opioid-induced hyperalgesia, development of opioid dependence, opioid reward, and opioid respiratory depression. However, the mechanism(s) contributing to opioid-induced proinflammatory actions remains unre...
BACKGROUND Postoperative opioid use following ileostomy reversal procedures contributes to postoperative ileus. We assessed the impact of a liposome bupivacaine-based, opioid-sparing multimodal analgesia regimen versus a standard opioid-based analgesia regimen on postsurgical opioid use. We also assessed health economic outcomes in patients undergoing ileostomy reversal at our institution, whic...
BACKGROUND Addiction to opioids, or opioid dependence, encompasses the biopsychosocial dysfunction seen in illicit heroin injectors, as well as aberrant behaviours in patients prescribed opioids for chronic nonmalignant pain. OBJECTIVE To outline the management of opioid dependence using opioid pharmacotherapy as part of a comprehensive chronic illness management strategy. DISCUSSION The sa...
Opioid and opioid-like receptors are activated by a variety of endogenous peptides including [Met]enkephalin (met), [Leu]enkephalin (leu), β-endorphin (β-end), α-neodynorphin, dynorphin A (dynA), B (dynB), big (Big dyn), nociceptin/orphanin FQ (N/OFQ); endomorphin-1 endomorphin-2 also potential peptides. The Greek letter nomenclature for the opioid receptors, μ, δ κ, is well established, NC-IUP...
background:naltrexone is a competitive opioid receptor antagonist blocking the euphoric effects of exogenous opioids. when used concomitantly with opioids, naltrexone causes severe withdrawal symptoms.the main aim of the study is to determine the symptomatology and outcome of patients who consumed naltrexone in conjunction with an opioid substance. methods:this cross-sectional study was perform...
Morphine injected locally to the paw of an adult or an infant rat is analgesic. Opiates specific to micro and kappa opioid receptors, and less consistently to delta opioid receptors, given locally to the site of injury in adult animals are also analgesic in a variety of models of inflammatory pain. To determine which opioid receptor(s) are involved in local analgesia in the immature animal, ago...
introduction: the present study aims to compare bile and urine samples of a corpse for detection of morphine. methods: in this cross-sectional study, forensic examination of the bodies placed 59 of the 366 referred corpses at the high suspicion of opioid overdose. urine and bile samples of the bodies were analyzed for morphine using thin layer chromatography. results: all samples were taken fro...
the aim of this study was to use site directed mutagenesis technique to construct a vector in which serine363 and serine375 residues of the cooh-terminal portion of the μ-opioid receptor (mor) were substituted by alanine. these constructs are essential in studying g-protein coupled receptor kinase-mediated mor desensiti-zation. the nested pcr carried out for conversion of serine363 and serine37...
Neuropathic pain often results from peripheral nerve damage, which can involve immune response. Local leukocyte-derived opioid peptides or exogenous opioid agonists inhibit neuropathy-induced mechanical hypersensitivity in animal models. Since neuropathic pain can also be augmented by heat, in this study we investigated the role of opioids in the modulation of neuropathy-evoked heat hypersensit...
Marketed New Drug Delivery Systems for Opioid Agonists/Antagonists Administration: A Rapid Overview
Novel drug delivery systems for controlled-release of opioid agonists as a long time painkillers or opioid antagonists for opium, heroin, and alcohol addiction are under development or in clinical use today. In this article, the field of “new drug delivery systems” is momentarily reviewed from the viewpoint of the marketed opioid agonists/antagonists dosage forms today.
