Spinal antinociceptive synergism between morphine and clonidine persists in mice made acutely or chronically tolerant to morphine. (1/4441)

Morphine (Mor) tolerance has been attributed to a reduction of opioid-adrenergic antinociceptive synergy at the spinal level. The present experiments tested the interaction of intrathecally (i.t.) administered Mor-clonidine (Clon) combinations in mice made acutely or chronically tolerant to Mor. ICR mice were pretreated with Mor either acutely (40 nmol i.t., 8 h; 100 mg/kg s.c., 4 h) or chronically (3 mg/kg s.c. every 6 h days 1 and 2; 5 mg/kg s.c. every 6 h days 3 and 4). Antinociception was detected via the hot water (52.5 degrees C) tail-flick test. After the tail-flick latencies returned to baseline levels, dose-response curves were generated to Mor, Clon, and Mor-Clon combinations in tolerant and control mice. Development of tolerance was confirmed by significant rightward shifts of the Mor dose-response curves in tolerant mice compared with controls. Isobolographic analysis was conducted; the experimental combined ED50 values were compared statistically against their respective theoretical additive ED50 values. In all Mor-pretreated groups, the combination of Mor and Clon resulted in significant leftward shifts in the dose-response curves compared with those of each agonist administered separately. In all tolerant and control groups, the combination of Mor and Clon produced an ED50 value significantly less than the corresponding theoretical additive ED50 value. Mor and Clon synergized in Mor-tolerant as well as in control mice. Spinally administered adrenergic/opioid synergistic combinations may be effective therapeutic strategies to manage pain in patients apparently tolerant to the analgesic effects of Mor.  (+info)

Modulation of Ca2+/calmodulin-dependent protein kinase II activity by acute and chronic morphine administration in rat hippocampus: differential regulation of alpha and beta isoforms. (2/4441)

Calcium/calmodulin-dependent protein kinase II (CaMK II) has been shown to be involved in the regulation of opioid receptor signaling. The present study showed that acute morphine treatment significantly increased both Ca2+/calmodulin-independent and Ca2+/calmodulin-dependent activities of CaMK II in the rat hippocampus, with little alteration in the protein level of either alpha or beta isoform of CaMK II. However, chronic morphine treatment, by which rats were observed to develop apparent tolerance to morphine, significantly down-regulated both Ca2+/calmodulin-independent and Ca2+/calmodulin-dependent activities of CaMK II and differentially regulated the expression of alpha and beta isoforms of CaMK II at protein and mRNA levels. Application of naloxone or discontinuation of morphine treatment after chronic morphine administration, which induced the withdrawal syndrome of morphine, resulted in the overshoot of CaMK II (at both protein and mRNA levels) and its kinase activity. The phenomena of overshoot were mainly observed in the beta isoform of CaMK II but not in the alpha isoform. The effects of both acute and chronic morphine treatments on CaMK II could be completely abolished by the concomitant application of naloxone, indicating that the effects of morphine were achieved through activation of opioid receptors. Our data demonstrated that both acute and chronic morphine treatments could effectively modulate the activity and the expression of CaMK II in the hippocampus.  (+info)

Absence of G-protein activation by mu-opioid receptor agonists in the spinal cord of mu-opioid receptor knockout mice. (3/4441)

1. The ability of mu-opioid receptor agonists to activate G-proteins in the spinal cord of mu-opioid receptor knockout mice was examined by monitoring the binding to membranes of the non-hydrolyzable analogue of GTP, guanosine-5'-O-(3-[35S]thio)triphosphate ([35S]GTPgammaS). 2. In the receptor binding study, Scatchard analysis of [3H][D-Ala2,NHPhe4,Gly-ol]enkephalin ([3H]DAMGO; mu-opioid receptor ligand) binding revealed that the heterozygous mu-knockout mice displayed approximately 40% reduction in the number of mu-receptors as compared to the wild-type mice. The homozygous mu-knockout mice showed no detectable mu-binding sites. 3. The newly isolated mu-opioid peptides endomorphin-1 and -2, the synthetic selective mu-opioid receptor agonist DAMGO and the prototype of mu-opioid receptor agonist morphine each produced concentration-dependent increases in [35S]GTPgammaS binding in wild-type mice. This stimulation was reduced by 55-70% of the wild-type level in heterozygous, and virtually eliminated in homozygous knockout mice. 4. No differences in the [35S]GTPgammaS binding stimulated by specific delta1- ([D-Pen2,5]enkephalin), delta2-([D-Ala2]deltorphin II) or kappa1-(U50,488H) opioid receptor agonists were noted in mice of any of the three genotypes. 5. The data clearly indicate that mu-opioid receptor gene products play a key role in G-protein activation by endomorphins, DAMGO and morphine in the mouse spinal cord. They support the idea that mu-opioid receptor densities could be rate-limiting steps in the G-protein activation by mu-opioid receptor agonists in the spinal cord. These thus indicate a limited physiological mu-receptor reserve. Furthermore, little change in delta1-, delta2- or kappa1-opioid receptor-G-protein complex appears to accompany mu-opioid receptor gene deletions in this region.  (+info)

Behavioral and physiological effects of remifentanil and alfentanil in healthy volunteers. (4/4441)

BACKGROUND: The subjective and psychomotor effects of remifentanil have not been evaluated. Accordingly, the authors used mood inventories and psychomotor tests to characterize the effects of remifentanil in healthy, non-drug-abusing volunteers. Alfentanil was used as a comparator drug. METHODS: Ten healthy volunteers were enrolled in a randomized, double-blinded, placebo-controlled, crossover trial in which they received an infusion of saline, remifentanil, or alfentanil for 120 min. The age- and weight-adjusted infusions (determined with STANPUMP, a computer modeling software package) were given to achieve three predicted constant plasma levels for 40 min each of remifentanil (0.75, 1.5, and 3 ng/ml) and alfentanil (16, 32, and 64 ng/ml). Mood forms and psychomotor tests were completed, and miosis was assessed, during and after the infusions. In addition, analgesia was tested at each dose level using a cold-pressor test. RESULTS: Remifentanil had prototypic micro-like opioid subjective effects, impaired psychomotor performance, and produced analgesia. Alfentanil at the dose range tested had more mild effects on these measures, and the analgesia data indicated that a 40:1 potency ratio, rather than the 20:1 ratio we used, may exist between remifentanil and alfentanil. A psychomotor test administered 60 min after the remifentanil infusion was discontinued showed that the volunteers were still impaired, although they reported feeling no drug effects. CONCLUSIONS: The notion that the pharmacodynamic effects of remifentanil are extremely short-lived after the drug is no longer administered must be questioned given our findings that psychomotor effects were still apparent 1 h after the infusion was discontinued.  (+info)

Comparison of three solutions of ropivacaine/fentanyl for postoperative patient-controlled epidural analgesia. (5/4441)

BACKGROUND: Ropivacaine, 0.2%, is a new local anesthetic approved for epidural analgesia. The addition of 4 microg/ml fentanyl improves analgesia from epidural ropivacaine. Use of a lower concentration of ropivacaine-fentanyl may further improve analgesia or decrease side effects. METHODS: Thirty patients undergoing lower abdominal surgery were randomized in a double-blinded manner to receive one of three solutions: 0.2% ropivacaine-4 microg fentanyl 0.1% ropivacaine-2 microg fentanyl, or 0.05% ropivacaine-1 microg fentanyl for patient-controlled epidural analgesia after standardized combined epidural and general anesthesia. Patient-controlled epidural analgesia settings and adjustments for the three solutions were standardized to deliver equivalent drug doses. Pain scores (rest, cough, and ambulation), side effects (nausea, pruritus, sedation, motor block, hypotension, and orthostasis), and patient-controlled epidural analgesia consumption were measured for 48 h. RESULTS: All three solutions produced equivalent analgesia. Motor block was significantly more common (30 vs. 0%) and more intense with the 0.2% ropivacaine-4 microg fentanyl solution. Other side effects were equivalent between solutions and mild in severity. A significantly smaller volume of 0.2% ropivacaine-4 microg fentanyl solution was used, whereas the 0.1% ropivacaine-2 microg fentanyl group used a significantly greater amount of ropivacaine and fentanyl. CONCLUSIONS: Lesser concentrations of ropivacaine and fentanyl provide comparable analgesia with less motor block despite the use of similar amounts of ropivacaine and fentanyl. This finding suggests that concentration of local anesthetic solution at low doses is a primary determinant of motor block with patient-controlled epidural analgesia after lower abdominal surgery.  (+info)

Transdermal nitroglycerine enhances spinal sufentanil postoperative analgesia following orthopedic surgery. (6/4441)

BACKGROUND: Sufentanil is a potent but short-acting spinal analgesic used to manage perioperative pain. This study evaluated the influence of transdermal nitroglycerine on the analgesic action of spinal sufentanil in patients undergoing orthopedic surgery. METHODS: Fifty-six patients were randomized to one of four groups. Patients were premedicated with 0.05-0.1 mg/kg intravenous midazolam and received 15 mg bupivacaine plus 2 ml of the test drug intrathecally (saline or 10 microg sufentanil). Twenty to 30 min after the spinal puncture, a transdermal patch of either 5 mg nitroglycerin or placebo was applied. The control group received spinal saline and transdermal placebo. The sufentanil group received spinal sufentanil and transdermal placebo. The nitroglycerin group received spinal saline and transdermal nitroglycerine patch. Finally, the sufentanil-nitroglycerin group received spinal sufentanil and transdermal nitroglycerine. Pain and adverse effects were evaluated using a 10-cm visual analog scale. RESULTS: The time to first rescue analgesic medication was longer for the sufentanil-nitroglycerin group (785+/-483 min) compared with the other groups (P<0.005). The time to first rescue analgesics was also longer for the sufentanil group compared with the control group (P<0.05). The sufentanil-nitroglycerin group group required less rescue analgesics in 24 h compared with the other groups (P<0.02) and had lesser 24-h pain visual analog scale scores compared with the control group (P<0.005), although these scores were similar to the sufentanil and nitroglycerin groups (P>0.05). The incidence of perioperative adverse effects was similar among groups (P>0.05). CONCLUSIONS: Transdermal nitroglycerine alone (5 mg/day), a nitric oxide generator, did not result in postoperative analgesia itself, but it prolonged the analgesic effect of spinal sufentanil (10 microg) and provided 13 h of effective postoperative analgesia after knee surgery.  (+info)

Nitrocinnamoyl and chlorocinnamoyl derivatives of dihydrocodeinone: in vivo and in vitro characterization of mu-selective agonist and antagonist activity. (7/4441)

Two 14beta-p-nitrocinnamoyl derivatives of dihydrocodeinone, 14beta-(p-nitrocinnamoylamino)-7,8-dihydrocodeinone (CACO) and N-cyclopropylmethylnor-14beta-(p-nitrocinnamoylamino)- 7, 8-dihydrocodeinone (N-CPM-CACO), and the corresponding chlorocinnamoylamino analogs, 14beta-(p-chlorocinnamoylamino)-7, 8-dihydrocodeinone (CAM) and N-cyclopropylmethylnor-14beta-(p-chlorocinnamoylamino) -7, 8-dihydrocodeinone (MC-CAM), were tested in opioid receptor binding assays and the mouse tail-flick test to characterize the opioid affinity, selectivity, and antinociceptive properties of these compounds. In competition binding assays, all four compounds bound to the mu opioid receptor with high affinity. When bovine striatal membranes were incubated with any of the four dihydrocodeinones, binding to the mu receptor was inhibited in a concentration-dependent, wash-resistant manner. Saturation binding experiments demonstrated that the wash-resistant inhibition of mu binding was due to a decrease in the Bmax value for the binding of the mu-selective peptide [3H][D-Ala2, MePhe4,Gly(ol)5] enkephalin and not a change in the Kd value, suggesting an irreversible interaction of the compounds with the mu receptor. In the mouse 55 degrees C warm water tail-flick test, both CACO and N-CPM-CACO acted as short-term mu-selective agonists when administered by i. c.v. injection, whereas CAM and MC-CAM produced no measurable antinociception at doses up to 30 nmol. Pretreatment of mice for 24 h with any of the four dihydrocodeinone derivatives produced a dose-dependent antagonism of antinociception mediated by the mu but not the delta or kappa receptors. Long-term antagonism of morphine-induced antinociception lasted for at least 48 h after i.c. v. administration. Finally, shifts in the morphine dose-response lines after 24-h pretreatment with the four dihydrocodeinone compounds suggest that the nitrocinnamoylamino derivatives may produce a greater magnitude long-term antagonism of morphine-induced antinociception than the chlorocinnamoylamino analogs.  (+info)

Antinociceptive properties of the new alkaloid, cis-8, 10-di-N-propyllobelidiol hydrochloride dihydrate isolated from Siphocampylus verticillatus: evidence for the mechanism of action. (8/4441)

The antinociceptive action of the alkaloid cis-8, 10-di-n-propyllobelidiol hydrochloride dehydrate (DPHD), isolated from Siphocampylus verticillatus, given i.p., p.o., i.t., or i.c.v., was assessed in chemical and thermal models of nociception in mice, such as acetic acid-induced abdominal constriction, formalin- and capsaicin-induced licking, and hot-plate and tail-flick tests. DPHD given by i.p., p.o., i.t., or i.c.v. elicited significant and dose-related antinociception. At the ID50 level, DPHD was about 2- to 39-fold more potent than aspirin and dipyrone, but it was about 14- to 119-fold less potent than morphine. Its analgesic action was reversed by treatment of animals with p-chlorophenylalanine, naloxone, cyprodime, naltrindole, nor-binaltrorphimine, L-arginine, or pertussis toxin. Its action was also modulated by adrenal-gland hormones but was not affected by gamma-aminobutyric acid type A or type B antagonist, bicuculine, or phaclofen, nor was it affected by glibenclamide. DPHD, given daily for up to 7 days, did not develop tolerance to itself nor did it induce cross-tolerance to morphine. However, animals rendered tolerant to morphine presented cross-tolerance to DPHD. The antinociception of DPHD was not secondary to its anti-inflammatory effect, nor was it associated with nonspecific effects such as muscle relaxation or sedation. DPHD, in contrast to morphine, did not decrease charcoal meal transit in mice, nor did it inhibit electrical field stimulation of the guinea pig ileum or mouse vas deferens in vitro. Thus, DPHD produces dose-dependent and pronounced systemic, spinal, and supraspinal antinociception in mice, including against the neurogenic nociception induced by formalin and capsaicin. Its antinociceptive effect involves multiple mechanisms of action, namely interaction with mu, delta, or kappa opioid systems, L-arginine-nitric oxide and serotonin pathways, activation of Gi protein sensitive to pertussis toxin, and modulation by endogenous glucocorticoids.  (+info)

Prescription of opioid medications for the treatment of chronic noncancer pain has become common. Chronic opioid therapy (COT) is complicated by balancing pain relief with the risk of misuse. Prescription opioids are the fastest growing form of drug abuse and the most common cause of unintentional overdose.1,2 Misuse of prescribed opioids may be an important link between rising rates of opioid-related abuse and overdoses.3,4. The National Institute for Drug Abuse defines prescription opioid misuse as taking a medication in a manner other than that prescribed or for a different condition than that for which the medication is prescribed.5 Other definitions of opioid misuse exist. The addiction literature often focuses on such aberrant behavior as giving opioid medications to or getting them from others.6,7 In primary care settings, misuse is often defined as nonadherence, generally meaning taking more medication than prescribed and asking for early refills.8 The National Institute for Drub Abuse ...

Background. The utilisation of pharmaceutical opioids has increased internationally, and there is evidence of increasing risky alcohol consumption with ageing. This study examines the patterns and correlates of risky drinking among people with chronic non-cancer pain (CNCP) prescribed opioids, and the associations between alcohol consumption and pain.. Methods. The Pain and Opioids IN Treatment cohort comprises 1514 people in Australia prescribed pharmaceutical opioids for CNCP. Participants reported lifetime, past year and past month alcohol use, as well as mental and physical health, other substance use, pain characteristics, and current opioid dose.. Results. Less than one-tenth of the sample were lifetime abstainers (7%); 34% were former drinkers; 34% were non-risky drinkers (i.e., past 12 month use ≤4 standard drinks); 16% were occasional risky drinkers; and 8% were regular risky drinkers (i.e., ≥weekly use of >4 standard drinks). Males reported greater levels of alcohol use, ...
The use of opioid medications for the treatment of chronic non-cancer pain has risen dramatically in the past two decades. There are a number of risks associated with the long term use of opioids, most notably the potential for misuse. Successful opioid management strategies for chronic non-cancer pain depend upon effective patient-provider communication. Improving the communication between providers and patients about opioids has tremendous potential to improve opioid management and reduce opioid misuse.. The purpose of this pilot study is to evaluate how patients with chronic non-cancer pain and their physicians communicate about opioid management. The data from this pilot study will be used to guide further research on the mechanisms behind communication about opioid management and the design of an intervention to improve physician communication with patients with chronic non-cancer pain about opioid treatment. ...

We value Drs. Weinbergs and Baers careful review and feedback 1 on the 2017 Canadian Guideline for Opioids for Chronic Non-Cancer Pain2, and we would like to respond. The guideline has undergone external peer-review to evaluate the rigor that went into its development, as is the case with all research articles published in CMAJ. The current review was arranged to ensure that a financial conflict of interest declared by 1 of 15 voting panel members did not leave the guideline tainted by the influence of industry.3 In brief, the guidelines recommendations are to avoid opioids as first line therapy for chronic non-cancer pain, avoid prescribing opioids to individuals with past or present substance use disorder or other active psychiatric illness, to keep the daily dose of opioids below 90 mg (and ideally below 50 mg) morphine equivalent dose/day (MED/day) when opioids are prescribed, and to approach patients currently prescribed 90 mg MED/day or greater to very gradually reduce their opioid ...

The prescription of opioid analgesics by dental professionals is widespread in the United States. Policy makers, government agencies, and professional organizations consider this phenomenon a growing public health concern. This study examined trends in the prescription of opioid analgesics for adults by dental professionals and associated factors in the United States. Data from the Medical Expenditure Panel Survey (1996-2013) were analyzed. Descriptive statistics were calculated separately for each year. Logistic regression analyses were conducted to estimate the overall trend during the period with and without adjusting for dental procedures and personal characteristics. Survey weights were incorporated to handle the sampling design. The prescription of opioid analgesics following dental care increased over time. After adjusting for sociodemographic factors, source of payment, and type of dental procedure, the odds ratio (OR) of prescribing opioid analgesics following a dental visit per each decade
The HHS Guide for Clinicians on the Appropriate Dosage Reduction or Discontinuation of Long-Term Opioid Analgesics was developed for clinicians who are considering or beginning to reduce opioid dosage or to discontinue long-term opioid therapy for patients with chronic pain. Each clinician should review the risks and benefits of current therapy with his or her patient, and decide if tapering is appropriate based on individual circumstances.
The United States is in the midst of an opioid overdose epidemic to include overdoses involving prescription opioid medications, heroin, and illicit fentanyl (a powerful synthetic opioid medication that is increasingly being produced illicitly). In 2016, more than 42,000 people died from overdoses involving opioids, which is up from more than 33,000 deaths in 2015.. As in 2015, overdose deaths in 2016 involving prescription opioids (excluding the category of synthetic opioids that includes fentanyl) rose only slightly, suggesting that efforts in recent years to reduce the misuse of these drugs may be having an impact. Despite this, in 2016, 19,354 deaths involved an opioid medication and approximately 3.4 million people reported misusing such medications in the month prior to being interviewed.. In 2016, the overall increase in overdose deaths was driven in large part by continued sharp increases in deaths involving heroin and synthetic opioids such as fentanyl, but we know these trends are ...

Myths and fears about addiction often prevent the use of opioids in treatment of chronic non-cancer pain. This article presents guidelines for safe and appropriate prescribing of opioids, monitoring of patients, and avoiding legal problems.
In summary, long-acting opioids may increase vitality, social functioning, and mental health by providing extended periods of pain relief and fewer ADEs, compared with short-acting opioids.39 Dosing and product selection must be patient-specific. No single medication is perfect for every patient, and some patients may require the use of 2 long-acting opioids.56 Evaluation of treatment outcomes associated with opioid analgesics in chronic pain may be summarized by the 4 As: analgesia, activities of daily living, ADEs, and aberrant drug-related behaviors.57 Terminology Inconsistent use of terms related to pain often results in misunderstandings between regulators, health care providers, patients, and the general public regarding the use of opioids for the treatment of pain.58 The establishment of uniform definitions promotes enhanced patient care in patients receiving opioid therapy. It is vital to recognize that physical dependence, tolerance, cross-tolerance, addiction, and pseudoaddiction are ...
NPS Webinar: Join our panel of chronic pain experts as they discuss evidence-based approaches for managing chronic non-cancer pain and the role of pharmacists in reducing opioid-related harms.
Three studies are new to this update, resulting in five included studies in total (278 participants). Participants were primarily women (mean age 49.63 years, SD = 11.74) with different chronic pain conditions. We judged the studies too heterogeneous to pool data in a meta-analysis, so we have summarised the results from each study qualitatively. The studies included acupuncture, mindfulness, and cognitive behavioral therapy interventions aimed at reducing opioid consumption, misuse of opioids, or maintenance of chronic pain management treatments. We found mixed results from the studies. Three of the five studies reported opioid consumption at post-treatment and follow-up. Two studies that delivered Mindfulness-Oriented Recovery Enhancement or Therapeutic Interactive Voice Response found a significant difference between groups at post-treatment and follow-up in opioid consumption. The remaining study found reduction in opioid consumption in both treatment and control groups, and ...
After tramadol classification, the levels of monthly tramadol utilisation and the prevalence of tramadol users decreased by 12.9 defined daily dose/1000 registrants and 6.4 tramadol users/10000 registrants. In addition, the trends of monthly tramadol utilisation and the prevalence of tramadol users decreased by 1.6 defined daily dose/1000 registrants and 0.37 tramadol users/10000 registrants. The impacts of tramadol classification seems predominantly associated with the reduced accessibility of tramadol to both new and existing users. Of the 232 cases of opioid-related deaths, 62 (26.7%) cases did not receive any opioid in the one year before opioid-related death. Only 48 cases received a daily dose of opioid of more than 120 mg oral morphine equivalent (OMEQ) dose in the final year, and an opioid daily dose more than 120 mg OMEQ dose was not significantly associated with opioid-related deaths (adjusted odds ratios [aOR]: 1.4; 95% confidence interval [95%CI]: 0.52, 3.6). In addition, most of the ...
Of the 215,140 individuals who underwent a procedure within the study time frame and received and filled at least one prescription for opioid pain medication within 14 days of their procedure, 19 percent received at least one refill prescription. The median prescription lengths were 4 days for appendectomy and gallbladder removal, 5 days for inguinal hernia repair, 4 days for hysterectomy, 5 days for mastectomy, 5 days for anterior cruciate ligament repair and rotator cuff repair, and 7 days for discectomy. The early nadir (the initial prescription duration associated with the lowest modeled risk of refill) in the probability of refill was at an initial prescription of nine days for general surgery procedures (probability of refill, 10.7 percent), 13 days for womens health procedures (probability of refill, 16.8 percent), and 15 days for musculoskeletal procedures (probability of refill, 32.5 percent).. The study notes some limitations, including that it addresses only prescription opioid use ...
The major findings of this study are that indices of vascular age and arterial stiffness are worse in opioid-dependent patients compared with opioid naïve controls with mean calculated ages elevated by 1.97% in men and 13.43% in women. The effect was thus more marked in women. A significant effect was found on vascular age and augmentation index by exposure quartile after correction for CA and BMI. The RA/CA ratio was found to be related to power functions of the opioid duration of exposure in cross-sectional and longitudinal analyses. A dose-response relationship was demonstrated with lifetime opioid exposure. In particular, the effect of opioid exposure was robust, and remained after multiple adjustments in cross-sectional and longitudinal studies.. These findings should be interpreted in the light of the relatively modest degree of opioid exposure to which these patients were exposed. While the dose and duration of opioids used by patients in this study is typical of that seen in many ...

Treatment with analgesic drugs is the mainstay of cancer pain management. The major group of drugs used in cancer pain management is the opioid analgesics. During the last 30 years, there has been a dramatic increase in our knowledge of the sites and mechanism of action of the opioids. The development of analytical methods has also been of great importance in facilitating pharmacokinetic studies of the disposition and fate of opioids in patients. More recently, advances in genomic research have indicated the potential importance of pharmacogenetic factors in the response to opioid analgesics. These studies have begun to offer us a better understanding of some of the sources of variation between individuals in their response to opioids and to suggest ways of minimizing some of their adverse effects. This chapter presents a comprehensive discussion of the pre-clinical pharmacology and clinical aspects of opioid analgesia and the principles of opioid administration.
In the Extended-Release and Long-Acting Opioid Analgesics REMS, one of the elements to assure safe use is an education program for prescribers about the risks of opioid medications as well as safe prescribing and safe use practices. The ER/LA Opioid Analgesics REMS requires the manufacturers to provide commercial support to accredited CME so that it is available free of charge or at nominal cost to prescribers. However, the participation of accredited providers is completely voluntary - as is the participation of prescribers in REMS education.. ...
The µ-opioid receptor is the primary target structure of most opioid analgesics and thus responsible for the predominant part of their wanted and unwanted effects. Carriers of the frequent genetic µ-opioid receptor variant N40D (allelic frequency 8.2 - 17 %), coded by the single nucleotide polymorphism A,G at position 118 of the µ-opioid receptor coding gene OPRM1 (OPRM1 118A,G SNP), suffer from a decreased opioid potency and from a higher need of opioid analgesics to reach adequate analgesia. The aim of the present work was to identify the mechanism by which the OPRM1 118A,G SNP decreases the opioid potency and to quantify its effects on the analgesic potency and therapeutic range of opioid analgesics. To elucidate the consequences of the OPRM1 118A,G SNP for the effects of opioid analgesics, brain regions of healthy homozygous carriers of the OPRM1 118A,G SNP were identified by means of functional magnetic resonace imaging (fMRI), where the variant alters the response to opioid analgesics ...
Tramadol is a unique analgesic medication, available in variety of formulations, with both monoaminergic reuptake inhibitory and opioid receptor agonist activity increasingly prescribed worldwide as an alternative for high-affinity opioid medication in the treatment of acute and chronic pain. It is a prodrug that is metabolized by cytochrome P450 (CYP) enzymes CYP2D6 and CYP3A4 to its more potent opioid analgesic metabolites, particularly the O-demethylation product M1. The opioid analgesic potency of a given dose of tramadol is influenced by an individuals CYP genetics, with poor metabolizers experiencing little conversion to the active M1 opioid metabolite and individuals with a high metabolic profile, or ultra-metabolizers, experiencing the greatest opioid analgesic effects ...

Objectives. To analyze the prevalence in the use and dependence on opioid drugs in the Spanish population with chronic pain and evaluate the differences according to sex.. Patients and methods. The demographic variables, opioid treatment characteristics and use of other substances were assessed in 229 users of opioid drugs. A descriptive bivariate analysis of the data was performed.. Results. Forty-six percent of the patients met the criteria of dependence on opioid drugs (Diagnostic and Statistical Manual of Mental Disorders, 4th Edition [DSM-IV-TR]). Alcohol and cannabis consumption was greater in the men. The rates of dependence on the use of opioid drugs were significantly higher in the extended treatments.. Conclusions. Planning for treatments with opioids and strategies for preventing inappropriate use should not depend on the patients sex. We need further studies on the medical and psychological variables related to the use of and dependence on opioids.. ...
Evidence from behavioral and self-reported data suggests that the patients beliefs and expectations can shape both therapeutic and adverse effects of any given drug. We investigated how divergent expectancies alter the analgesic efficacy of a potent opioid in healthy volunteers by using brain imaging. The effect of a fixed concentration of the μ-opioid agonist remifentanil on constant heat pain was assessed under three experimental conditions using a within-subject design: with no expectation of analgesia, with expectancy of a positive analgesic effect, and with negative expectancy of analgesia (that is, expectation of hyperalgesia or exacerbation of pain). We used functional magnetic resonance imaging to record brain activity to corroborate the effects of expectations on the analgesic efficacy of the opioid and to elucidate the underlying neural mechanisms. Positive treatment expectancy substantially enhanced (doubled) the analgesic benefit of remifentanil. In contrast, negative treatment expectancy
The scope of the problem is vast - opioid overdose is now the second leading cause of accidental death in the United States, and the prevalence is second only to marijuana, said Thomas McLellan, director of the new Center for Substance Abuse Solutions at the University of Pennsylvania School of Medicine.. In a new study, McLellan and his colleagues found 11.7 percent of the 202 million opioid prescriptions issued in the United States in 2009 went to children and young adults. Additional research is needed to determine whether this relatively high rate of prescriptions is warranted, the researchers say. Medical professionals may need to consider alternative medications for young people in some situations, McLellan said.. The results also showed that 56 percent of opioid prescriptions given in 2009 went to patients who had already filled a prescription in the previous month. Not all of them may be justified, McLellan said.. More research is needed to see if current practices are working, with a ...
Background Use of pharmaceutical opioids (medicines that are used to treat pain) has increased dramatically in some parts of the world since the mid-1990s. With the increased use, there has been increasing numbers of people seeking treatment for dependence (addiction) on pharmaceutical opioids. Currently, most treatment guidelines are based on research that was conducted in people who were dependent on heroin (a highly addictive opioid). This review sought to compare different opioid agonist maintenance treatments (i.e. treatments such as methadone or buprenorphine that are given for at least 30 days to help the person to reduce their unsanctioned drug use) for the treatment of pharmaceutical opioid dependence. We also compared results from maintenance treatment to short term treatments such as detoxification (removal of the drug from the body) or psychological treatments (e.g. talking therapy, counselling).. Study characteristics We examined the scientific literature up to May 2015. We ...
Baltimore, Maryland, August 21, 2012. A new project by MedBiquitous will support data collection to measure the scope of continuing health care education on the risks of opioid medications, safe prescribing, and safe use practices. The project will meet the requirements of the FDAs extended-release and long-acting (ER/LA) opioid analgesics Risk Evaluation and Mitigation Strategy (ER/LA REMS). The MedBiquitous project is funded by the REMS Program Companies, a consortium of ER/LA opioid analgesics companies.. The centerpiece of the opioid REMS is an education program for clinicians who prescribe such drugs. The organizations that accredit continuing education in the health professions are working together to facilitate the development of the prescriber education. The education will involve teaching prescribers how to assess patients for treatment with ER/LA opioid analgesic therapy, initiate and manage therapy, modify dosing, and discontinue use. Prescribers will learn about the drugs, including ...

Fentanyl matrix is a transdermal (through the skin) system providing continuous delivery of fentanyl for 72 hours. Fentanyl matrix will be administered to patients with chronic (prolonged) non-cancer pain under routine practice during 12 weeks. Dose will be adjusted in accordance with patients degree of pain and treatment response in the investigators judgment ...
In 2013, a total of 43,982 deaths in the United States were attributed to drug poisoning, including 16,235 deaths (37%) involving opioid analgesics. From 1999 to 2013, the drug poisoning death rate more than doubled from 6.1 to 13.8 per 100,000 population, and the rate for drug poisoning deaths involving opioid analgesics nearly quadrupled from…

Opioid use is not associated with an increased risk of Alzheimers disease, shows a recent study from the University of Eastern Finland.
Currently, the USA has a problem with increased numbers of opioid-induced deaths. In a minority of the cases, the victims used prescription opioids. In most cases, they obtained these prescription opioids from illicit sources. Thus, they were not prescribed to them.2 3. In sharp contrast to this, the attention of the American press, insurance companies, administration and politicians focuses strongly on patients with pain. Recently, American academics even addressed Europe requesting that Europe reduces patient access to opioid analgesics.4 5 In May 2017, 12 USA congressmen wrote a letter to WHOs Director-General warning that a pharmaceutical company (Mundipharma) was promoting opioid analgesics in countries where pain management hardly exists. Aside from the fact that these congressmen hardly seem to understand that the USA is not Europe or the rest of the world, the letter is falsely suggesting that opioid-induced deaths from opioid analgesics are a serious problem in Europe.6 Moreover, pain ...
Since the isolation of morphine from opium in the 19th century, scientists have hoped to find a potent opioid analgesic that isnt addictive and doesnt cause respiratory arrest with increased doses.
Experts have agreed on treatment approaches to implement when troubling behaviors arise in patients receiving opioids for chronic pain.
Remifentanil is a potent, short-acting synthetic opioid analgesic drug. It is given to patients during surgery to relieve pain and as an adjunct to an anaesthetic. Remifentanil is used for sedation as well as combined with other medications for use in general anesthesia. The use of remifentanil has made possible the use of high-dose opioid and low-dose hypnotic anesthesia, due to synergism between remifentanil and various hypnotic drugs and volatile anesthetics. Remifentanil is used as an opioid analgesic that has a rapid onset and rapid recovery time. It has been used effectively during craniotomies, spinal surgery, cardiac surgery, and gastric bypass surgery. While opiates function similarly, with respect to analgesia, the pharmacokinetics of remifentanil allows for quicker post-operative recovery. It is administered in the form remifentanil hydrochloride and in adults is given as an intravenous infusion in doses ranging from 0.1 microgram per kilogram per minute to 0.5 (µg/kg)/min. Children ...

1. Tramadol analgesic causes respiratory depression that is mainly mediated by opioid receptors. However, Tramadol is a weak opioid receptor agonist, and its metabolites O-desmethyltramadol is only about 1/10 of morphine, and fentanyl is a strong opioid receptor agonist, its potency is about 100 times morphine. When the two together, to be a major contributor to opioid receptors is fentanyl. Pradeep Bhatia was also held this view (1). 2. Tramadol poisoning is overdose. Under normal usage the key is patients renal impairment and CYP2D6 gene duplication (2). We present a case of renal function in patients with normal. Further, in terms of Genotyping of CYP2D6, East Asian and Africans do not exist uitrarapid metabolizers (3).The CYP2D6*10 allele is the most common allele in the Chinese population, and correlated with a significantly In Response: The Cause of Fatal Respiratory Depression Is Combination of Clindamycin and Fentanyl, Rather than Tramadol
Doctors who limit the supply of opioids they prescribe to three days or less may help patients reduce their risk of dependence and addiction, according to research published in the March 17 issue of the U.S. Centers for Disease Control and Preventions Morbidity and Mortality Weekly Report.
Last week, the U.S. Food and Drug Administration held a two-day hearing to determine if more controls need to be placed on opioid prescribing. The hearing was the result of a citizens petition filed by the Physicians for Responsible Opioid Prescribing (PROP) and other advocates. The petition asks the FDA to change the indication on opioid analgesics like OxyContin from moderate to severe pain to severe pain and to include a suggested duration of 90 days of continuous use. Current labels on opioid analgesics simply indicate that opioids are to be used for moderate to severe pain, without further qualification.. The FDA is still taking comments before it makes its decision regarding this issue, and you can let it know what your views are here. To hear impact statements from those who testified at the meeting, go here.. Separately, the FDA is considering reclassifying hydrocodone-containing painkillers like Vicodin from Schedule III drugs to the more restrictive Schedule II. In January, an ...
Opioid analgesics are the drugs of choice for alleviating pain symptoms of moderate and high intensity in different fields of medicine. By degree of anesthetic effect, they are significantly superior to all non-narcotic drugs. Opioid drugs have central mechanism of action, realized by interaction with opioid receptors of different brain parts and central nervous system.. The most common opioid pain medication is Codeine. It has several dosage forms (tablets, syrup, injections) and it is widely used in clinical practice. Compliance with the rules for clinical use of all opioid drugs is a prerequisite for preventing risk of possible complications.. The main disadvantage of opioid drugs is a risk of drug dependence. Tolerance is caused by the persons addiction to the applied dose of an opioid and decrease in analgesic effect during prolonged therapy. Due to the increased risk of dependence, there is a special system for monitoring the use of opioids to prevent possible abuse in many ...
Read about a study finding that long-term use of opioids is common among people with Alzheimers disease in Finland, especially transdermal opioids.
Palliative care experts working at the global level believe that this system can help resolve some of the challenges with the supply of opioid analgesics by introducing a more efficient process for import and export licenses. A more reliable supply of opioid analgesics is critical for palliative care. It thus seems important for the palliative care movement to encourage governments around the world to start using the new system.. Requirements for import/export of opioid analgesics. The 1961 Single Convention on Narcotic Drugs requires countries to provide estimates of their requirements for opioid analgesics to the INCB, which then confirms and publishes the estimated requirement for each country. Countries can only import quantities of medications within that amount, although it is possible to submit supplementary estimates at any time during the year. Any movement of opioid analgesics across international borders requires import and export licenses, which are issued by the competent ...
The use of opioid analgesics for postoperative pain management has contributed to the global opioid epidemic. It was recently reported that prescription opioid analgesic use often continued after major joint replacement surgery even though patients were no longer experiencing joint pain. The use of epidural local analgesia for perioperative pain management was not found to be protective against persistent opioid use in a large cohort of opioid-naïve patients undergoing abdominal surgery. In a retrospective study involving over 390,000 outpatients more than 66 years of age who underwent minor ambulatory surgery procedures, patients receiving a prescription opioid analgesic within 7 days of discharge were 44% more likely to continue using opioids 1 year after surgery ...

Caffeine is a stimulant compound belonging to the xanthine class of chemicals naturally found in coffee, tea, and (to a lesser degree) cocoa or chocolate. It is included in many soft drinks, as well as a larger amount in energy drinks. Caffeine is the world's most widely used psychoactive drug and by far the most common stimulant. In North America, 90% of adults consume caffeine daily.[63] A few jurisdictions restrict its sale and use. Caffeine is also included in some medications, usually for the purpose of enhancing the effect of the primary ingredient, or reducing one of its side-effects (especially drowsiness). Tablets containing standardized doses of caffeine are also widely available. Caffeine's mechanism of action differs from many stimulants, as it produces stimulant effects by inhibiting adenosine receptors.[64] Adenosine receptors are thought to be a large driver of drowsiness and sleep, and their action increases with extended wakefulness.[65] Caffeine has been found to increase ...

  • Fentanyl is a synthetic opioid that is 75-200 times more potent than morphine sulfate and has a much shorter half-life. (
  • 4. A product according to claim 3 or 17 wherein the opioid analgesic is morphine or an acceptable salt thereof. (
  • T here has been growing concern among Australian medical professionals about the increase in prescribing of opioid analgesic preparations (particularly morphine and oxycodone) over the past decade. (
  • In studies with human SERT-transfected human HEK293 cells, the synthetic opioids tramadol, meperidine, methadone, tapentadol, and dextromethorphan inhibited SERT, but fentanyl and a number of phenanthrenes including morphine and hydromorphone did not. (
  • A potent opioid analgesic without addictive and respiratory adverse effects has been a predominant goal for opioid medicinal chemistry since the isolation of morphine from opium in the 19th century. (
  • Due to the compliance- reasons, only long acting opioids should be used (controlled release morphine preparations, methadone, buprenorphine) and the route of administration should always be oral. (
  • 2. Individual is receiving strong opioids (morphine, fentanyl, oxycodone, hydromorphone) for 3 weeks prior to enrollment. (
  • Additionally, the analgesic effect of post-operative morphine treatment was significantly reduced in the group that received the chronic morphine treatment prior to surgery compared with the group that did not, indicating that pre-operatively-treated mice had developed tolerance developed. (
  • To investigate whether the enhanced Bdnf and Pdyn gene and protein expression observed in the preoperative, morphine-treated mice was linked functionally with heightened analgesic tolerance and OIH, mice were treated with antagonists to Bdnf and Pdyn signaling. (
  • Additionally, co-administration of anacardic acid, a histone acetyltransferase inhibitor, with pre-operative morphine prevented OIH and opioid-induced tolerance observed in the mice that did not receive the inhibitor. (
  • When the analgesic effect of salmon-calcitonin (S-CT) and of eel-calcitonin (E-CT), as well as their influence on the morphine-analgesia were compared, no significant differences were found. (
  • The U.S. Food and Drug Administration today approved new labeling for Embeda (morphine sulfate and naltrexone hydrochloride) extended-release (ER) capsules, an opioid analgesic to treat pain severe enough to require daily, around-the-clock, long-term opioid treatment and for which alternative treatment options are inadequate. (
  • When crushed, the naltrexone in Embeda blocks some of the euphoric effects of the morphine and can precipitate withdrawal in persons dependent on opioids. (
  • Morphine and some other opioids do not have a ceiling effect (whenincreasing the dose above a certain level does not provide furtherrelief) and thus can be safely administered in increasing amountswithout risking an overdose, as long as side effects are tolerated. (
  • Opioid consumption data were collected and converted to oral morphine equivalent (OME). (
  • Design, setting, participants, & measurements Using the US Renal Data System, we conducted a cohort study evaluating the association between opioid use (modeled as a time-varying exposure and expressed in standardized oral morphine equivalents) and time to first emergency room visit or hospitalization for altered mental status, fall, and fracture among 140,899 Medicare-covered adults receiving hemodialysis in 2011. (
  • In contrast to morphine, repeated treatment with ABT-594 did not appear to elicit opioid-like withdrawal or physical dependence. (
  • RCT Comparing the Analgesic Efficacy of 4 Therapeutic Strategies Based on 4 Different Major Opioids (Fentanyl, Oxycodone, Buprenorphine vs Morphine) in Cancer Patients With Moderate/Severe Pain, at the Moment of Starting 3rd Step of WHO Analgesic Ladder. (
  • The 4 opioids more most commonly prescribed in Italy (oral morphine and oxycodone, fentanyl and buprenorphine transdermal), based on the data currently available, have an analgesic effect would partly overlap but with different percentages of non-responders (NR), a different need to increase the dose over time to maintain adequate analgesia, a different action to the switch to another molecule for ineffectiveness analgesic. (
  • In the 12-month SPACE (Strategies for Prescribing Analgesics Comparative Effectiveness) trial published March 6 in JAMA , the investigators reported randomizing a total of 240 patients to treatment with immediate-release opioids (morphine, oxycodone, or hydrocodone/acetaminophen) or acetaminophen or nonsteroidal anti-inflammatory drugs. (
  • Since the isolation of morphine from opium in the 19th century, scientists have hoped to find a potent opioid analgesic that isn't addictive and doesn't cause respiratory arrest with increased doses. (
  • Opioids such as morphine , heroin , codeine , and oxycodone , which are collected from poppies, are a type of medical anesthesia and are used as analgesics for cancer. (
  • Morphine pharmacology in β -arrestin-2 knockout mice suggested that a ligand that promotes coupling of the μ -opioid receptor (MOR) to G proteins, but not β -arrestins, would result in higher analgesic efficacy, less gastrointestinal dysfunction, and less respiratory suppression than morphine. (
  • In mice and rats, TRV130 is potently analgesic while causing less gastrointestinal dysfunction and respiratory suppression than morphine at equianalgesic doses. (
  • Morphine is the archetypal opioid ( Hamilton and Baskett, 2000 ) and is still considered a mainstay of analgesic therapy. (
  • Another option is to start low doses of a strong opioid, such as morphine, at step two. (
  • Codeine is a prodrug that must be metabolised to morphine by the liver enzyme CYP2D6 to achieve most of its analgesic effect. (
  • When crushed, the naltrexone in the drug blocks some of the euphoric effects of the morphine and can precipitate withdrawal in persons dependent on opioids. (
  • Social attachment was demonstrated to be mediated by the opioid system through experiments administering morphine and naltrexone, an opioid agonist and antagonist, to juvenile guinea pigs. (
  • Opioid (also called narcotic) analgesics work by binding to receptors on cells mainly in the brain, spinal cord and gastrointestinal system. (
  • Here we report a functional profile of a unique analog, BU08028, targeting a combination of a classical and nonclassical opioid receptors in monkeys. (
  • The involvement of opioid receptors in the analgesic mechanism was investigated using naloxone antagonism. (
  • The analgesic effect involved activation of opioid receptors in the central nervous system, where both spinal and supraspinal components might be involved. (
  • Metabolites of PLE could be responsible for activation of opioid receptors. (
  • Opioid receptors are highly versatile signaling molecules. (
  • Compounds with activity like OPIATE ALKALOIDS, acting at OPIOID RECEPTORS. (
  • 2. While on isolated tissues, E-CT induced a significant increase on the effect of bremazocine, [D-Pen2,D- Pen5]enkephalin and [Met5]enkephalin and no changes were observed on the effect of DAMGO, suggesting that E-CT increases the effects of opioids acting on delta or kappa receptors but not on mu receptors. (
  • His research has focused on opioid receptors and their mechanisms of action, resulting in over 300 publications. (
  • This study, which was conducted in 12 non-human primates, targeted a combination of classical (MOP) and non-classical (NOP) opioid receptors. (
  • In 2018, the development of 'AT-121' that works on opioid receptors was reported. (
  • Less than half of the analgesic effect is via the mu-opioid receptors. (
  • Opioid analgesics, chemistry and receptors. (
  • Opioid receptors are a group of inhibitory G protein-coupled receptors with opioids as ligands. (
  • The opioid receptors are ~40% identical to somatostatin receptors (SSTRs). (
  • Opioid receptors are distributed widely in the brain, in the spinal cord, on peripheral neurons, and digestive tract. (
  • There are four major subtypes of opioid receptors. (
  • However it was subsequently found that it shares little sequence similarity with the other opioid receptors, and has quite different function. (
  • Phylogenetic analysis demonstrates that the family of opioid receptors was already present at the origin of jawed vertebrates over 450 million years ago. (
  • Tetraploidization events often result in the loss of one or more of the duplicated genes, but in this case, nearly all species retain all four opioid receptors, indicating biological significance of these systems. (
  • Thus, mu-opioid receptors induce relaxation, trust, satisfaction and have a strong analgesic effect. (
  • This points to a role for opioid receptors in mating behaviors. (
  • However, mu-opioid receptors don't have specificity for regulating social behaviour as they induce a relaxing effect in a wide spectrum of non-social contexts. (
  • The functionality of kappa- and delta-opioid receptors, might be less associated with relaxation and analgesic effects as kappa-OR often suppress activation of mu-opioid receptors, and delta-OR differ from mu-OR in its interaction with agonists and antagonists. (
  • Kappa-opioid receptors were implicated in perceptual mobilization seen in chronic anxiety whereas delta-opioid receptors were found to induce initiation of actions, impulsivity and behavioural mobilization. (
  • These differences led some researches to suggest that up- or down-regulations within three opioid receptors families are the basis of different dispositional emotionality seen in psychiatric disorders. (
  • However, in order to obtain complete analgesia, a combination of an NMDA receptor antagonist and an opioid receptor agonist is needed. (
  • Since then, numerous reports have appeared, and the generally agreed view, at present, is that the N 2 O analgesia is never fully antagonized by opioid antagonists and that it involves other unidentified actions [7] . (
  • Results demonstrated that PLE exhibited a potent dose dependent analgesic activity in all tested models for analgesia. (
  • Many hospitals use patient-controlled analgesia (PCA), a system in which the analgesics are given intravenously (by vein), and the patient can control the dose by pushing a button on a pump. (
  • Hydromorphone HCl is a pure opioid agonist with the principal therapeutic activity of analgesia . (
  • Lysine residue acetylation in histone proteins in spinal cord cells is an epigenetic mechanism that contributes to nociceptive sensitization, tolerance to opioid analgesia and OIH after surgical incision. (
  • norBNI) reduced OIH and improved the efficacy of opioid analgesia in mice that were exposed to chronic opioid administration preoperatively. (
  • Preventing prescription opioid abuse and ensuring that patients have access to appropriate treatments for pain are both top public health priorities for the FDA,' said Sharon Hertz, M.D., acting director of the Division of Anesthesia, Analgesia, and Addiction Products in the FDA's Center for Drug Evaluation and Research. (
  • The authors believe that their findings indicate that advanced administration of preoperative oral analgesia trended towards a decrease in immediate postoperative opioid use when compared to immediate preoperative administration. (
  • Thus, ABT-594 may be an analgesic that lacks the problems associated with opioid analgesia. (
  • The effect of a fixed concentration of the μ-opioid agonist remifentanil on constant heat pain was assessed under three experimental conditions using a within-subject design: with no expectation of analgesia, with expectancy of a positive analgesic effect, and with negative expectancy of analgesia (that is, expectation of hyperalgesia or exacerbation of pain). (
  • Can postoperative analgesia be improved by the choice and timing of analgesics? (
  • It elicits analgesia by stimulating the μ -opioid receptor (MOR), a G protein-coupled receptor (GPCR) highly expressed in the central nervous system and gastrointenstinal tract. (
  • Furthermore, patients can develop tolerance to opioid analgesia, necessitating dose escalation and risking worsening tolerability ( Schneider and Kirsh, 2010 ). (
  • and can be dose-limiting, as many patients would rather suffer reduced analgesia than continue opioid use and contend with serious gastrointestinal discomfort. (
  • It has similar effects to other opioid derivatives, such as analgesia, sedation, nausea and respiratory depression. (
  • Doctors once reserved opioids (also called narcotics) for treating severe acute pain, such as that from surgery or a broken bone but in more recent years, opioids have been increasingly prescribed for chronic pain, such as pain from arthritis. (
  • But opioid use for chronic (non-cancer) pain is controversial because they're associated with a high risk of abuse, addiction and accidental overdose. (
  • Certain factors predict the suitability of long-term opioid use for individuals with chronic pain. (
  • Opioids are used to treat acute pain related to surgery and other medical procedures, as well as for persistent (chronic) and breakthrough pain that is moderate to severe. (
  • Commonly reported reasons for treatment with opioid analgesics during pregnancy included surgical procedures, infections, chronic diseases, and injuries. (
  • The transdermal form of fentanyl is used only for chronic pain conditions in opioid-tolerant patients. (
  • Ballantyne JC, Mao J. Opioid therapy for chronic pain. (
  • The need for chronic opioids to treat persistent noncancer pain. (
  • While the role of opioid analgesics has been established in the treatment of cancer pain, reservations persist about appropriate use in patients with chronic noncancer pain. (
  • While it is legitimate medical practice to prescribe opioid analgesics to patients with chronic noncancer pain, there is clear evidence that prescribing is affected by concerns of regulatory sanctions. (
  • There is a continued need for comprehensive training of general practitioners in assessing patients with chronic non-malignant pain and prescribing of opioids for these patients, to minimise the potential for harms associated with use of these medications. (
  • Opioid analgesics are a class of prescription medications intended to treat chronic pain, but they have a significant potential for abuse. (
  • Based on this, guidelines for long-term opioid administration are established for chronic pain conditions of non-cancer origin. (
  • Most physicians felt it lawful and acceptable medical practice to prescribe opioids for chronic cancer pain, but only half held this view if the pain was not related to cancer. (
  • Opioids used to treat chronic pain have a high abuse potential. (
  • The purpose of this study is to determine the effectiveness of buprenorphine in treating opioid dependent individuals who abuse opioids that are prescribed for chronic pain. (
  • Many individuals who take opioids for chronic pain abuse the opioid medication. (
  • The HHS Guide for Clinicians on the Appropriate Dosage Reduction or Discontinuation of Long-Term Opioid Analgesics was developed for clinicians who are considering or beginning to reduce opioid dosage or to discontinue long-term opioid therapy for patients with chronic pain. (
  • Abstract: The use of long-term opioids (LTOs) to treat chronic pain of nonmalignant origin (CNMP) is controversial. (
  • Opioids are commonly used to treat acute and chronic pain despite the negative side-effects that are associated with chronic opioid use, such as analgesic tolerance and increased sensitivity to pain (opioid-induced hyperalgesia, or OIH). (
  • In April 2016, a group led by Dr. J. David Clark (Stanford University and the Veterans Affairs Palo Alto Health Care System) reported in the journal Molecular Pain that chronic opioid exposure induces epigenetic changes in the spinal cord that enhance pain severity and duration after surgery. (
  • The discovery of these changes provide possible targets for therapeutic development aimed at decreasing opioid-induced hypersensitivity and analgesic tolerance that is confounded by surgical procedures in chronic opioid users. (
  • Taken together, these data show that chronic opioid exposure induces epigenetic changes that alter nociceptive signaling. (
  • Additionally, the data suggests that therapies that target the BDNF-TrkB and dynorphin-KOR signaling pathways might combat the post-operative increases to pain sensitivity and analgesic tolerance that are associated with pre-operative chronic opioid use. (

  • Chronic pain management guidelines recommend the use of long-acting, extended-release (ER) analgesics because they provide prolonged, more consistent plasma concentrations of drug compared with short-acting agents, thus minimizing fluctuations that could contribute to end-of-dose breakthrough pain.
