Endogenous opioids activate opioid receptors (ORs) in the enteric nervous system to control intestinal motility and secretion. The mu OR mediates the deleterious side effects of opioid analgesics, including constipation, respiratory depression and addiction. Although the delta OR (DOR) is a promising target for analgesia, the function and regulation of DOR in the colon are poorly understood. This study provides evidence that endogenous opioids activate DOR in myenteric neurons which may regulate colonic motility...

Background The use of opioids for chronic non-cancer pain (CNCP) remains very controversial. There are a number of randomized controlled trials (RCTs) showing efficacy and safety in the short-term, but long-term data are limited. Methods This article contains 10 case reports (followed to 2011) that were selected from a survey of 84 patients with intractable CNCP treated with opioids and followed every 3 months now for a median of 10 years. The previous published survey of this group reported outcomes of pain severity, adverse effects, pain relief, satisfaction, mood, problematic opioid use, tolerance, physical dependency, functional status, health-related quality of life (HRQL), immune status and sexual function...

Background: The efficacy and safety of naldemedine (a peripherally-acting µ-opioid receptor antagonist) for opioid-induced constipation (OIC) in subjects with cancer was demonstrated in the primary report of a phase 3, double-blind study (COMPOSE-4) and its open-label extension (COMPOSE-5). The primary endpoint, the proportion of spontaneous bowel movement (SBM) responders, was met. Here, we report results from secondary endpoints including quality of life (QOL) assessments from these studies...

Objectives: To examine the efficacy and safety of lubiprostone for the treatment of opioid-induced constipation (OIC) in patients by opioid class received. Design: Data were pooled from three phase III, randomized, double-blind, placebo-controlled studies. Subjects/Setting: Adults with chronic noncancer pain receiving opioid therapy for 30 or more days and diagnosed with OIC. Methods: Overall mean change from baseline in spontaneous bowel movement (SBM) frequency, overall treatment response (≥1 SBM/week improvement over baseline SBM frequency in all treatment weeks with available data and ≥3 SBMs/week for ≥9 of the 12 weeks of treatment), and OIC-related symptoms were examined in patients taking opioids...

Novel pain killers without adverse effects are urgently needed. Opioids induce central and intestinal side effects such as respiratory depression, sedation, addiction, and constipation. We have recently shown that a newly designed agonist with a reduced acid dissociation constant (pKa ) abolished pain by selectively activating peripheral μ-opioid receptors (MOR) in inflamed (acidic) tissues without eliciting side effects. Here, we extended this concept in that pKa reduction to 7.22 was achieved by placing a fluorine atom at the ethylidene bridge in the parental molecule fentanyl...

Chronic constipation is a very common medical problem with relevant impact on the patients' quality of life. Modern definitions recognize constipation as a polysymptomatic disorder, including various aspects of disturbed defecation. Current guidelines recommend a stepwise approach in the management of chronic constipation. Isolated or concomitant evacuation disorders should be identified and may need differential/additional treatment. Baseline measures include lifestyle components and bulking agents. The next step recommends treatment with conventional laxatives...

Opioids are potent analgesics used for the treatment of acute and chronic pain. Side-effects are common and among the most bothersome are those associated with opioid-induced bowel dysfunction, which includes opioid-induced constipation. In this Review, we provide a summary of the pathophysiology, diagnosis, and management of opioid-induced constipation, which can be defined as a change in baseline bowel habit or defecatory patterns following initiation, alteration, or increase of opioid therapy. Opioid-induced constipation is a consequence of the action of opioids on their receptors in the gastrointestinal tract...

BACKGROUND: Opioid-induced bowel dysfunction (OIBD) is characterised by constipation, incomplete evacuation, bloating, and gastric reflux. It is one of the major adverse events of treatment for pain in cancer and in palliative care, resulting in increased morbidity and reduced quality of life.This is an update of two Cochrane reviews. One was published in 2011, Issue 1 on laxatives and methylnaltrexone for the management of constipation in people receiving palliative care; this was updated in 2015 and excluded methylnaltrexone...

Aims Opioid treatment is associated with gastrointestinal (GI) side effects, known as opioid-induced bowel dysfunction (OIBD). Symptoms of OIBD are caused by opioid receptor activation in the enteric nervous system, which results in increased GI transit time and increased faecal volume in the colon. OIBD can be experimentally induced in healthy participants through oral oxycodone treatment. The aim of this study was to investigate whether administration of naloxegol, a peripherally restricted opioid antagonist, could reduce GI symptoms, GI transit time, and colorectal volume, using an experimental model of OIBD...

Background Opioid analgesics inhibit anal sphincter function and contribute to opioid-induced bowel dysfunction. However, it is unknown if the inhibition can be reduced by opioid antagonism with oral naloxone, and how this compares to osmotic laxative treatment. Aims To compare the effects of oxycodone and macrogol 3350 treatment (OX + PEG) versus combined oral oxycodone and naloxone (OXN) on anal sphincter function and gastrointestinal symptoms. Methods A randomised, double-blind, crossover trial was conducted in 20 healthy, male volunteers...

BACKGROUND: The management of postoperative pain and recovery is still unsatisfactory in a number of cases in clinical practice. Opioids used for postoperative analgesia are frequently associated with adverse effects, including nausea and constipation, preventing smooth postoperative recovery. Not all patients are suitable for, and benefit from, epidural analgesia that is used to improve postoperative recovery. The non-opioid, lidocaine, was investigated in several studies for its use in multimodal management strategies to reduce postoperative pain and enhance recovery...

For improving the QOL of patients diagnosed with cancer, early palliative care is recommended, aiming to minimize pain and opioid-induced side effects. Herein, we evaluated the effect of continuous interventions for pain management and opioid-induced side effects in outpatients with cancer. Pharmacists continuously performed interventions on patients on their hospital visits, starting from the first visit for opioid introduction to intervention via telephone. We recorded their pain patterns and intensities, use of rescue doses, and types and degrees of side effects during these interventions...

A Kuo, M T Smith
Outbred rodent stocks including Sprague Dawley rats, are known for their genetic diversity and so they are often used to develop animal models of human disease. Although between-colony differences in pharmaco-behavioural studies have been published previously, a direct head-to-head comparison study, whereby all research was performed in the same laboratory by the same experimenter utilising the supraspinal route of drug administration in the same strain of rat, is lacking. Herein, we report our head-to-head comparison study, involving assessment of antinociception, constipation and respiratory depression evoked by single bolus intracerebroventricular (ICV) doses of morphine, buprenorphine, DPDPE and U69,593 using male Sprague Dawley rats sourced from a different breeding colony (BC2) from that (BC1) used by us previously...
