AIM: To compare the analgesic efficacy of epidural and i.v. oxycodone at the same dose. METHODS: In this randomised, double-blind, double-dummy clinical trial 30 women, aged 24-67 years, undergoing elective gynaecologic laparotomy were administrated either i.v. saline and epidural oxycodone 0.1 mg·kg-1 (EPI-group; n=15) or i.v. oxycodone 0.1 mg·kg-1 and epidural saline (IV-group; n=15). For multimodal analgesia patients received i.v. paracetamol and dexketoprofen, and a triple-mixture epidural infusion after the first four postoperative hours...

Relapse to nonmedical use of prescription opioids often occurs after exposure to places previously associated with drug use. Here, we describe a rat model of context-induced reinstatement of oxycodone seeking after repeated cycles of drug self-administration and extinction-induced abstinence. We also determined the role of mu, delta, and kappa opioid receptors (MOR, DOR, KOR) in this reinstatement. We trained rats to self-administer oxycodone for 6 h/d in Context A; lever pressing was paired with a discrete cue...

BACKGROUND: Inter-patient variability in response to opioids is well known but a comprehensive definition of its pathophysiological mechanism is still lacking and, more importantly, no studies have focused on children. The STOP Pain project aimed to evaluate the risk factors that contribute to clinical response and adverse drug reactions to opioids by means of a systematic review and a clinical investigation on paediatric oncological patients. METHODS: We conducted a systematic literature search in EMBASE and PubMed up to the 24th of November 2016 following Cochrane Handbook and PRISMA guidelines...

BACKGROUND: Diverted prescription opioids are significant contributors to drug overdose mortality. Street price has been suggested as an economic metric of the diverted prescription opioid black market. This study examined variables that may influence the street price of diverted oxycodone and oxymorphone. METHODS: A cross-sectional study was conducted utilizing data from the previously validated, crowdsourcing website StreetRx. Street price reports of selected oxycodone and oxymorphone products, between August 22, 2014 and June 30, 2016, were considered for analysis...

BACKGROUND: Acute musculoskeletal pain is one of the most commonly reported symptoms among patients visiting the emergency department (ED). Treatment with over-the-counter pain medications, given by nurses, results in improved pain management and reduces the waiting time to drug administration without significant side effects. Opioid analgesics are extensively used for acute pain in the ED. Compared to morphine, oxycodone has a much more specific pharmacological activity, higher analgesic potential, and more tolerable side effects...

This article provides an updated practical guide for the treatment of primary restless legs syndrome (RLS). Articles that appeared after the American Academy of Neurology guideline search were reviewed according to the same evidence rating schedule. We found limited evidence for nonpharmacologic treatment options. In moderate to severe primary RLS, pharmacologic options may be considered, including iron suppletion, an α2δ ligand, a dopamine agonist, a combination of an α2δ ligand and a dopamine agonist, or oxycodone/naloxone...

The objective of the current review was to update the previous evidence-based medicine review of treatments for restless legs syndrome published in 2008. All randomized, controlled trials (level I) with a high quality score published between January 2007 and January 2017 were reviewed. Forty new studies qualified for efficacy review. Pregabalin, gabapentin enacarbil, and oxycodone/naloxone, which did not appear in the previous review, have accrued data to be considered efficacious. Likewise, new data enable the modification of the level of efficacy for rotigotine from likely efficacious to efficacious...

PURPOSE: In clinical practice, using different opioid analgesics is common during the induction and maintenance of general anesthesia and for postoperative analgesia. However, if the opioid analgesic could be limited to a single drug, we hypothesized that the risk of adverse drug interactions could be reduced, with fewer adverse effects. We examined the use of oxycodone as a single opioid in a well-defined cohort of orthopedic patients undergoing general anesthesia. METHODS: In this retrolective, monocentric investigation, we reviewed data from 83 patients who underwent general anesthesia and received intravenous oxycodone as the sole analgesic (0...

BACKGROUND AND PURPOSE: Oxycodone is a potent semi-synthetic opioid that is commonly used for the treatment of severe acute and chronic pain. However, treatment with oxycodone can lead to cardiac electrical changes, such as long-QT syndrome, potentially inducing sudden cardiac arrest. Here, we investigate whether the cardiac side effects of oxycodone can be explained by modulation of the cardiac sodium channel Nav1.5. EXPERIMENTAL APPROACH: Heterologously expressed Nav1...

There is growing experience translating genomic data into clinical practice, as seen with the Implementing GeNomics In pracTicE (IGNITE) network. A primary example is the influence of CYP2D6 genotype on the beneficial and adverse effects of some opioids. Clinical recommendations exist to guide drug therapy based on CYP2D6 genotype for codeine, tramadol, oxycodone and hydrocodone, although the level of supporting evidence differs by drug. Limited evidence also supports the use of genetic data to guide other medications in chronic pain therapy, including tricyclic antidepressants and celecoxib...

Opioid analgesics, such as morphine, oxycodone and fentanyl, are the cornerstones for treating moderate to severe pain. However, upon chronic administration, their efficiency is limited by prominent side effects such as analgesic tolerance and dependence liability. Neuropeptide FF (NPFF) and its receptors (NPFF1R and NPFF2R) are recognized as an important pronociceptive system involved in opioid-induced hyperalgesia and analgesic tolerance. Herein, we report the design of multitarget peptidomimetic compounds that show high affinity binding to the mu opioid receptor (MOPr) and NPFFRs...

BACKGROUND: Nociceptin/orphanin FQ (NOP) receptor ligands have shown efficacy as putative analgesics and can modulate the abuse-related effects of opioids, suggesting therapeutic applications. The discriminative stimulus effects of a drug are related to their subjective effects, a predictor of abuse potential. To determine whether activation of NOP receptors could alter the subjective effects of an abused opioid analgesic, a novel oxycodone discrimination was established in mice, characterized with positive and negative controls, and its expression evaluated with a NOP receptor agonist...

Heroin and fentanyl are the overwhelming and increasing cause of opioid deaths in Milwaukee County, Wisconsin. We reviewed all drug and opioid deaths from 2013 to 2017 to delineate the specific opioid drugs involved and changes in their incidence. From 2013 to 2017, 980 deaths were due to opioids, rising from 184 in 2013 to 337 in 2017. In 2017, opioid deaths exceeded combined non-natural deaths from homicide and suicide. Illicit heroin and fentanyl/analogs caused 84% of opioid deaths and 80% of drug deaths, with no increase in deaths due to oral prescription drugs such as oxycodone and hydrocodone...

The increase in opioid prescribing in many European countries over the last decade has raised concerns about associated diversion, overdose, and mortality. Fentanyl is one of these synthetic opioids that is typically prescribed as a transdermal patch for pain that requires continuous pain relief and has been the focus of investigation due to reports of overdose and death. We report a case series of 14 drug addiction treatment entrants, who entered treatment in a service located in the region of Southern Denmark from August 2015 to December 2015 for smoking fentanyl patches...
