    Combining opioid medications and alcohol has serious implications for patient health, including overdose. Information regarding those who use/misuse opioid medications and engage in unhealthy alcohol use is limited to pharmacological and epidemiological descriptions. This study presents opioid medication misuse and behavioral, mental, and physical health characteristics of persons filling opioid medications that are engaged in unhealthy alcohol use. We conducted a cross-sectional survey at 5 community pharmacies in Southwestern, Pennsylvania among patients filling opioid medications. Respondents completed validated opioid medication misuse, alcohol use, illicit drug use, depression, posttraumatic stress disorder (PTSD), and physical health functioning assessments. We present univariate and multivariate statistics describing opioid medication misuse and health risks among those positive for unhealthy alcohol use. A total of 344 patients completed the survey (75.8% response). A total of 15.9% of respondents screened positive for opioid medication misuse, of whom 20.3% reported unhealthy alcohol use. Taking opioid medications too often was reported among a larger proportion of the sample with unhealthy alcohol use (34.3%) compared to those without (22.1%, p=0.04). Further, among respondents with unhealthy alcohol use, illicit drug use (Adjusted odds ratio [AOR]=12.14, 95% Confidence Interval [CI]=1.64-89.72) and PTSD (AOR=9.77, 95% CI=1.70-56.11) were associated with increased odds for opioid medication misuse. Results suggest respondents with unhealthy alcohol use had distinct health profiles, which may place them at risk for opioid misuse and adverse events, such as overdose. Continued research must work to further understand these relationships and identify intervention and treatment strategies. Copyright © 2017 Elsevier B.V. All rights reserved.

    Purpose This study investigated the patterns of opioid co-prescription with benzodiazepine and other concomitant medications among opioid users. Opioid dose in each type of co-prescription was also examined. Patients and methods This cross-sectional study was conducted among opioid users receiving concomitant medications at an outpatient tertiary hospital setting in Malaysia. Opioid prescriptions (morphine, fentanyl, oxycodone, dihydrocodeine and tramadol) that were co-prescribed with other medications (opioid + benzodiazepines, opioid + antidepressants, opioid + anticonvulsants, opioid + antipsychotics and opioid + hypnotics) dispensed from January 2013 to December 2014 were identified. The number of patients, number of co-prescriptions and the individual mean opioid daily dose in each type of co-prescription were calculated. Results A total of 276 patients receiving 1059 co-prescription opioids with benzodiazepine and other co-medications were identified during the study period. Of these, 12.3% of patients received co-prescriptions of opioid + benzodiazepine, 19.3% received opioid + anticonvulsant, 6.3% received opioid + antidepressant and 10.9% received other co-prescriptions, including antipsychotics and hypnotics. The individual mean opioid dose was <100 mg/d of morphine equivalents in all types of co-prescriptions, and the dose ranged from 31 to 66 mg/d in the co-prescriptions of opioid + benzodiazepine. Conclusion Among the opioid users receiving concomitant medications, the co-prescriptions of opioid with benzodiazepine were prescribed to 12.3% of patients, and the individual opioid dose in this co-prescription was moderate. Other co-medications were also commonly used, and their opioid doses were within the recommended dose. Future studies are warranted to evaluate the adverse effect and clinical outcomes of the co-medications particularly in long-term opioid users with chronic non-cancer pain. PMID:28182128

    Fourteen states and the District of Columbia have legalized the use of cannabis for medical purposes. A small, high-quality literature supports the efficacy of medical cannabis for the treatment of neuropathic pain. The smoked botanical product, however, is associated with a number of adverse medical and psychiatric consequences. Furthermore, experimental data indicate that acute use of cannabis results in impairment of every important metric related to the safe operation of a motor vehicle. Epidemiological data show associations between recent cannabis use and both psychomotor impairment and motor vehicle crashes, associations that are strengthened by the concomitant use of alcohol and other central nervous system depressants. Finally, data from pain clinics reveals an unusually high prevalence of cannabis use in nearly all age groups and an association between cannabis use and opioid and other substance misuse. Based on available data and expert opinion, concomitant use of cannabis and opioids is an absolute contraindication to the operation of a motor vehicle. In patients who use cannabis and are prescribed opioids, heightened vigilance for opioid- and other substance-related problems is warranted. It is appropriate to refrain from prescribing opioids to individuals using medical cannabis if there is reasonable suspicion that the combination will pose a risk to the patient or others.

    Opioid medications are commonly used to treat moderate-to-severe pain. While these medications are generally an effective means of pain control, they can, in rare cases, actually exacerbate the pain. This paradoxical reaction is called opioid-induced hyperalgesia (OIH). Patients experiencing OIH may benefit from decreasing or discontinuing the opioid, switching to an alternative opioid, and/or using a nonopioid medication for pain.

    Full Text Available Introduction: Emergency departments (EDs may be high-yield venues to address opioid deaths with education on both overdose prevention and appropriate actions in a witnessed overdose. In addition, the ED has the potential to equip patients with nasal naloxone kits as part of this effort. We evaluated the feasibility of an ED-based overdose prevention program and described the overdose risk knowledge, opioid use, overdoses, and overdose responses among participants who received overdose education and naloxone rescue kits (OEN and participants who received overdose education only (OE. Methods: Program participants were surveyed by telephone after their ED visit about their substance use, overdose risk knowledge, history of witnessed and personal overdoses, and actions in a witnessed overdose including use of naloxone. Results: A total of 415 ED patients received OE or OEN between January 1, 2011 and February 28, 2012. Among those, 51 (12% completed the survey; 37 (73% of those received a naloxone kit, and 14 (27% received OE only. Past 30-day opioid use was reported by 35% OEN and 36% OE, and an overdose was reported by 19% OEN and 29% OE. Among 53% (27/51 of participants who witnessed another individual experiencing an overdose, 95% OEN and 88% OE stayed with victim, 74% OEN and 38% OE called 911, 26% OEN and 25% OE performed rescue breathing, and 32% OEN (n=6 used a naloxone kit to reverse the overdose. We did not detect statistically significant differences between OEN and OE-only groups in opioid use, overdose or response to a witnessed overdose. Conclusion: This is the first study to demonstrate the feasibility of ED-based opioid overdose prevention education and naloxone distribution to trained laypersons, patients and their social network. The program reached a high-risk population that commonly witnessed overdoses and that called for help and used naloxone, when available, to rescue people. While the study was retrospective with a low

    On April 25, 2015, a massive 8.1-magnitude earthquake struck Nepal at 2:11 pm (Beijing time). The 68-member-strong China International Search & Rescue Team (CISAR) left for Nepal at 6 am, April 26, to help with relief work. The CISAR was the first foreign team to rescue a survivor who was trapped beneath the rubble in the Gongabu area after the earthquake. On May 8, the team fulfilled the search-and-rescue mission and returned to Beijing. During the 2 weeks of rescue work, the team treated more than 3700 victims and cleared approximately 430 buildings. In this rescue mission, 10 experienced medical officers (including nine doctors and a nurse) from the General Hospital of Chinese People's Armed Police Force (PAP) comprised the medical team of CISAR. In this report, we focus on the medical rescues by CISAR and discuss the characteristics of the medical rescue in Nepal. (Disaster Med Public Health Preparedness. 2016;page 1 of 3).

    Background: Opioid analgesics are high-alert medications known to cause adverse drug events. Objectives: The purpose of this study was to determine the cause of opioid incidents requiring administration of naloxone, an opioid reversal agent. The specific objectives were to determine the number of opioid incidents and the proportion of incidents documented through occurrence reporting and to characterize the incidents by phase in the medication-use process, by type of incident, and by drug responsible for toxic effects. Methods: A retrospective chart analysis was conducted using records from 2 acute care centres in the Regina Qu’Appelle Health Region. The study included inpatients who received naloxone for reversal of opioid toxicity resulting from licit, in-hospital opioid use. Cases were classified as preventable or nonpreventable. Preventable cases were analyzed to determine the phase of the medication-use process during which the incident occurred. These cases were also grouped thematically by the type of incident. The drug most likely responsible for opioid toxicity was determined for each case. The proportion of cases documented by occurrence reporting was also noted. Results: Thirty-six cases involving administration of naloxone were identified, of which 29 (81%) were deemed preventable. Of these 29 preventable cases, the primary medication incident occurred most frequently in the prescribing phase (23 [79%]), but multiple phases were often involved. The cases were grouped into 6 themes according to the type of incident. Morphine was the drug that most frequently resulted in toxic effects (18 cases [50%]). Only two of the cases (5.6%) were documented by occurrence reports. Conclusion: Preventable opioid incidents occurred in the acute care centres under study. A combination of medication safety initiatives involving multiple disciplines may be required to decrease the incidence of these events and to better document their occurrence. PMID:24159230

    Full Text Available Abstract Background Opioid maintenance treatment (OMT has a positive impact on substance use and health outcomes among HIV-infected opioid dependent patients. The present study investigates non-medical use of opioids by HIV-infected opioid-dependent individuals treated with buprenorphine or methadone. Methods The MANIF 2000 study is a longitudinal study that enrolled a cohort of 476 HIV-infected opioid-dependent individuals. Data were collected in outpatient hospital services delivering HIV care in France. The sample comprised all patients receiving OMT (either methadone or buprenorphine who attended at least one follow-up visit with data on adherence to OMT (N = 235 patients, 1056 visits. Non-medical use of opioids during OMT was defined as having reported use of opioids in a non-medical context, and/or the misuse of the prescribed oral OMT by an inappropriate route of administration (injection or sniffing. After adjusting for the non-random assignment of OMT type, a model based on GEE was then used to identify predictors of non-medical use of opioids. Results Among the 235 patients, 144 (61.3% and 91 (38.9% patients were receiving buprenorphine and methadone, respectively, at baseline. Non-medical use of opioids was found in 41.6% of visits for 83% of individual patients. In the multivariate analysis, predictors of non-medical use of opioids were: cocaine, daily cannabis, and benzodiazepine use, experience of opioid withdrawal symptoms, and less time since OMT initiation. Conclusions Non-medical use of opioids was found to be comparable in OMT patients receiving methadone or buprenorphine. The presence of opioid withdrawal symptoms was a determinant of non-medical use of opioids and may serve as a clinical indicator of inadequate dosage, medication, or type of follow-up. Sustainability and continuity of care with adequate monitoring of withdrawal symptoms and polydrug use may contribute to reduced harms from ongoing non-medical use of opioids.

    Objective The aim of this study was to examine trends and associated factors in the prescription of opioid analgesics, non-opioid analgesics, opioid and non-opioid analgesic combinations and no analgesics by emergency physicians for nontraumatic dental condition (NTDC)-related visits. Our secondary aim was to investigate whether race/ethnicity is a possible predictor of receiving a prescription for either type of medication for NTDC visits in emergency departments (EDs) after adjustment for potential covariates. Methods We analyzed data from the National Hospital Ambulatory Medical Care Survey for 1997–2000 and 2003–2007, and used multinomial multivariate logistic regression to estimate the probability of receiving a prescription for opioid analgesics, non-opioid analgesics, or a combination of both compared to receiving no analgesics for NTDC-related visits. Results During 1997–2000 and 2003–2007, prescription of opioid analgesics and combinations of opioid and non-opioid analgesics increased and that of no analgesics decreased over time. The prescription rates for opioid analgesics, non-opioid analgesics, opioid and non-opioid analgesic combinations and no analgesics for NTDC-related visits in EDs were 43%, 20%, 12% and 25% respectively. Majority of patients categorized as having severe pain received prescriptions for opioids for NTDC-related visits in EDs. After adjusting for covariates, patients with self-reported dental reasons for visit and severe pain had a significantly higher probability of receiving prescriptions for opioid analgesics and opioid and non-opioid analgesic combinations. Conclusion Prescription of opioid analgesics increased over time. ED physicians were more likely to prescribe opioid analgesics and opioid and non-opioid analgesic combinations for NTDC-related visits with reported severe pain. PMID:24863407

    Prescription drug abuse is the fastest growing drug problem in the United States, and the increase in unintentional drug overdose deaths has been driven by the increase in opioid analgesic use. Given the epidemic of non-medical prescription pain reliever use and the current medico-legal climate, it is increasingly important for the prescriber to monitor for medication compliance. The purpose of this IRB approved study is to compare the results of oral fluid (OF) and routine urinalysis for monitoring compliance in a single academic pain management program in an urban setting in order to evaluate the utility of OF analysis in compliance monitoring when prescribing opioid medications. Outcomes analysis of prospective, consecutive, paired comparison study with clinical implications. Single academic interventional pain management center in the United States. Paired OF and urine specimens were collected for each patient with signed informed consent, at the Institute for Pain Medicine, Western Pennsylvania Hospital, from patients who routinely donated urine on a random basis for compliance testing. A total of 153 paired specimens were analyzed. Demographic and prescription data were made available. Specimens were screened using immunoassay and presumptive positive findings were confirmed with liquid-chromatography and mass spectrometry. Although both matrices were tested for a wider range of medications, the data presented here are representative of analgesic opioids and benzodiazepine drug classes only. Following exclusion criteria, of the 132 remaining specimen pairs that were positive for opioids or benzodiazepines in at least one matrix, 101 pairs showed exact drug class matches (76.5%). In an additional 21 pairs, at least one drug class was positive in both matrices (15.9%), giving an overall agreement of 92.4%. Overall, 191 positive results were found in urine averaging 1.4 drugs per specimen; 176 positives were detected using OF for an average of 1.3 drugs per

  20. Cannabis as a Substitute for Opioid-Based Pain Medication: Patient Self-Report.

    Reiman, Amanda; Welty, Mark; Solomon, Perry

    2017-01-01

    Introduction: Prescription drug overdoses are the leading cause of accidental death in the United States. Alternatives to opioids for the treatment of pain are necessary to address this issue. Cannabis can be an effective treatment for pain, greatly reduces the chance of dependence, and eliminates the risk of fatal overdose compared to opioid-based medications. Medical cannabis patients report that cannabis is just as effective, if not more, than opioid-based medications for pain. Materials and Methods: The current study examined the use of cannabis as a substitute for opioid-based pain medication by collecting survey data from 2897 medical cannabis patients. Discussion: Thirty-four percent of the sample reported using opioid-based pain medication in the past 6 months. Respondents overwhelmingly reported that cannabis provided relief on par with their other medications, but without the unwanted side effects. Ninety-seven percent of the sample "strongly agreed/agreed" that they are able to decrease the amount of opiates they consume when they also use cannabis, and 81% "strongly agreed/agreed" that taking cannabis by itself was more effective at treating their condition than taking cannabis with opioids. Results were similar for those using cannabis with nonopioid-based pain medications. Conclusion: Future research should track clinical outcomes where cannabis is offered as a viable substitute for pain treatment and examine the outcomes of using cannabis as a medication assisted treatment for opioid dependence.

    To better understand postoperative opioid use after dermatologic surgery. Prospective observational study. Academic dermatology department. The study included 212 adults (1) who were undergoing a single skin excision (including Mohs micrographic surgery), (2) who consented to participate,and (3) who were able to be reached by telephone on postoperative day 3 or 4. Patients who did not meet these criteria and those referred to another physician for further surgical treatment or repair were excluded. The study examined(1) the incidence of opioid prescription after dermatologic surgery, (2) the percentage of prescribed opioid pain medications used in the postoperative period, and (3) patient and surgical characteristics associated with opioid pain medication prescription and use. Opioids were prescribed to 72 of the 212 patients(34%). Twenty-five of the 72 patients (35%) who were prescribed opioids did not use them. Forty-nine of 57 patients (86%) who filled an opioid prescription had leftover pills, and 26 of the 49 patients (53%) planned to keep them. Only maximum pain score was significantly associated with opioid use. Opioids were over prescribed after dermatologic surgery. Patients who had left over opioids did not dispose of them properly, which could lead to potential misuse and abuse.

    Medical rescue teams might be exposed to the risk of accidental poisoning while performing rescue procedures. Exposure to the risk of lethal carbon dioxide (CO2) concentrations is a rare situation. This case study describes rescuing a patient who suffered from sudden cardiac arrest due to accidental CO2 poisoning. The victim was finally evacuated and resuscitated, but the circumstances of the rescue operation point to the need to equip ambulances with carbon dioxide detectors and hermetic oxygen masks.

    Non-medical use (NMU) of prescription opioids in youth is of concern since they may continue this pattern into adulthood and become addicted or divert medications to others. Research into risk factors for NMU can help target interventions to prevent non-medical use of opioids in youth. The National Monitoring of Adolescent Prescription Stimulants Study (N-MAPSS) was conducted from 2008 to 2011. Participants 10-18years of age were recruited from entertainment venues in urban, rural and suburban areas of 10 US cities. Participants completed a survey including questions on their use of prescription opioids. NMU was defined as a non-labeled route of administration or using someone else's prescription. Information on age, gender, alcohol, marijuana and tobacco use was also collected. Summary descriptive, chi-square statistics and logistic regression were conducted using SAS 9.4. Of the 10,965 youth who provided information about past 30day prescription opioid use, prevalence of reported opioid use was 4.8% with 3.2% reported as NMU (n=345) and 1.6% as medical use (MU) only (n=180). More males than females (55.7% vs. 44.4%) reported opioid NMU (p<0.0001). Logistic regression revealed that among males (comparing NMU to MU only), current smokers were 4.4 times more likely to report opioid NMU than non-smokers (95% CI: 1.8, 10.7). Among females (comparing NMU to MU only), current smokers and alcohol users were more likely to report opioid NMU than those who had never smoked or used alcohol (OR=3.2, 95% CI: 1.4, 7.0 and OR=4.1, 95% CI: 1.7, 10.4, respectively). These results suggest that further research on gender differences in opioid NMU is needed; interventions for opioid NMU may need to be gender specific to obtain the best results.

    : Risks of abuse, misuse and diversion of opioids are of concern. Obtaining opioid prescriptions from multiple prescribers, known as opioid shopping, is a way in which opioids may be abused and diverted. Previous studies relied on counting the number of prescribers or number of pharmacies a subject goes to in a year to define shopping behaviour, but did not distinguish successive prescribers from concomitant prescribers. : The aim of the study was to assess the frequency of opioid overlapping prescriptions from different prescribers, compare it with diuretics and benzodiazepines, and provide a definition of shopping behaviour that differentiates opioids from diuretics, avoiding the inappropriate flagging of individuals with legitimate use of opioids. : Population-based cohort study using the IMS LRx database. This database covers 65% of all retail prescriptions in the US and includes mail service and specialty pharmacy provider prescriptions independent of the method of payment. : Ambulatory. : Subjects with at least one dispensing for any type of opioid in 2008. Similar cohorts were created for subjects exposed to benzodiazepines or diuretics. Analyses were performed separately for naïve subjects and those with prior use. : Frequency of overlapping prescriptions defined as at least 1 day of overlapping dispensing of prescriptions written by two or more different prescribers at any time during an 18-month period. : A total of 25 161 024 subjects exposed to opioids were included, of whom 13.1% exhibited at least one episode of overlapping prescriptions during 18 months of follow-up. Almost 10% of subjects exposed to benzodiazepines and 13.8% of subjects exposed to diuretics exhibited a similar behaviour. Having overlapping prescriptions dispensed by three or more pharmacies differentiates opioids from the other medication classes. Using that criterion, the overall risk of shopping behaviour was 0.18% in subjects exposed to opioids, 0.10% in subjects exposed to

    Pain and sleep disturbance have been shown to have a profound influence on the outcomes of cancer treatment. This study sought to determine whether administering opioid analgesics or sleeping medication to cancer patients during their first admission to a hospital is associated with poor prognoses. We conducted a population-based retrospective cohort study by analyzing data obtained from the National Health Insurance Research Database in Taiwan. The study population comprised cancer patients whose first admission to a hospital for initial cancer treatment was in 2004. We collected data on 2302 cancer patients. To analyze the effect of opioid analgesic and sleeping medication usage on cancer patient survival, we compared the 3-year survival rates among 4 groups of patients (no use, sleeping medications-only, opioid analgesics-only, both used). The 3-year Kaplan-Meier plots for these 4 groups show that the difference was statistically significant (log rank 48.244, p opioid analgesics-only group, and finally, the group in which both sleeping medications and opioid analgesics were used. The use of opioid analgesics or sleeping medication was shown to be negatively correlated with the survival rate of cancer patients. Copyright © 2014 Elsevier Ltd. All rights reserved.

    The Space Shuttle Hubble repair mission (STS-125) is unique in that a rescue mission (STS-400) has to be ready to launch before STS-125 life support runs out should the vehicle become stranded. The shuttle uses electrical power derived from fuel cells that use cryogenic oxygen and hydrogen (CRYO) to run all subsystems including the Environmental Control System. If the STS-125 crew cannot return to Earth due to failure of a critical subsystem, they must power down all nonessential systems and wait to be rescued by STS-400. This power down will cause the cabin temperature to be 60 F or less and freeze the rest of the vehicle, preventing it from attempting a reentry. After an emergency has been declared, STS-125 must wait at least 7 days to power down since that is the earliest that STS-400 can be launched. Problem The delayed power down of STS-125 causes CYRO to be consumed at high rates and limits the survival time after STS-400 launches to 10 days or less. CRYO will run out sooner every day that the STS-400 launch is delayed (weather at launch, technical issues etc.). To preserve CRYO and lithium hydroxide (LiOH - carbon dioxide removal) the crew will perform no exercise to reduce their metabolic rates, yet each deconditioned STS-125 crewmember must perform an EVA to rescue himself. The cabin may be cold for 10 days, which may cause shivering, increasing the metabolic rate of the STS-125 crew. Solution To preserve LiOH, the STS-125 manifest includes nutrition bars with low carbohydrate content to maintain crew respiratory quotient (RQ) below 0.85 as opposed to the usual shuttle galley food which is rich in carbohydrates and keeps the RQ at approximately 0.95. To keep the crew more comfortable in the cold vehicle warm clothing also has been included. However, with no exercise and limited diet, the deconditioned STS-125 crew returning on STS-400 may not be able to egress the vehicle autonomously requiring a supplemented crash-and-rescue capability.

    During long-term opioid therapy for chronic noncancer pain, monitoring medication adherence of patients with a history of aberrant opioid medication-taking behaviors (AMTB) is an essential practice. There is limited research, however, into the concordance among existing monitoring tools of self-report, physician report, and biofluid screening. This study examined associations among patient and provider assessments of AMTB and urine drug screening using data from a randomized trial of a cognitive-behavioral intervention designed to improve medication adherence and pain-related outcomes among 110 opioid-treated patients with chronic pain who screened positive for AMTB and were enrolled in a pain program. Providers completed the Aberrant Behavior Checklist (ABC) and patients completed the Current Opioid Misuse Measure (COMM) and the Chemical Coping Inventory (CCI). In multivariate analyses, ABC scores were compared with COMM and CCI scores, while controlling for demographics and established risk factors for AMTB, such as pain severity. Based on clinical cutoffs, 84% of patients reported clinically significant levels of AMTB and providers rated 36% of patients at elevated levels. Provider reports of AMTB were not correlated with COMM or CCI scores. However, the ABC ratings of experienced providers (nurse practitioners/attending physicians) were higher than those of less experienced providers (fellows) and were correlated with CCI scores and risk factors for AMTB. Associations between patient- and provider-reported AMTB and urine drug screening results were low and largely nonsignificant. In conclusion, concordance between patient and provider reports of AMTB among patients with chronic pain prescribed opioid medication varied by provider level of training.

    For the past few years, disasters like earthquakes, landslides, mudslides, tsunamis, and traffic accidents have occurred with an ever-growing frequency, coverage, and intensity greatly beyond the expectation of the public. In order to respond effectively to disasters and to reduce casualties and property damage, countries around the world have invested more efforts in the theoretical study of emergency medicine and the construction of emergency medical rescue forces. Consequently, emergency medical rescue teams of all scales and types have come into being and have played significant roles in disaster response work. As the only state-level emergency medical rescue force from the Chinese People's Armed Police Forces, the force described here has developed, through continuous learning and practice, a characteristic mode in terms of grouping methods, equipment system construction, and training.

    Major earthquakes often result in incalculable environmental damage, loss of life, and threats to health. Tremendous progress has been made in response to many medical challenges resulting from earthquakes. However, emergency medical rescue is complicated, and great emphasis should be placed on its organisation to achieve the best results. The 2008 Wenchuan earthquake was one of the most devastating disasters in the past 10 years and caused more than 370,000 casualties. The lessons learnt from the medical disaster relief effort and the subsequent knowledge gained about the regulation and capabilities of medical and military back-up teams should be widely disseminated. In this Review we summarise and analyse the emergency medical rescue efforts after the Wenchuan earthquake. Establishment of a national disaster medical response system, an active and effective commanding system, successful coordination between rescue forces and government agencies, effective treatment, a moderate, timely and correct public health response, and long-term psychological support are all crucial to reduce mortality and morbidity and promote overall effectiveness of rescue efforts after a major earthquake.

    Objectives. To assess the association between medical marijuana laws (MMLs) and the odds of a positive opioid test, an indicator for prior use. Methods. We analyzed 1999–2013 Fatality Analysis Reporting System (FARS) data from 18 states that tested for alcohol and other drugs in at least 80% of drivers who died within 1 hour of crashing (n = 68 394). Within-state and between-state comparisons assessed opioid positivity among drivers crashing in states with an operational MML (i.e., allowances for home cultivation or active dispensaries) versus drivers crashing in states before a future MML was operational. Results. State-specific estimates indicated a reduction in opioid positivity for most states after implementation of an operational MML, although none of these estimates were significant. When we combined states, we observed no significant overall association (odds ratio [OR] = 0.79; 95% confidence interval [CI] = 0.61, 1.03). However, age-stratified analyses indicated a significant reduction in opioid positivity for drivers aged 21 to 40 years (OR = 0.50; 95% CI = 0.37, 0.67; interaction P < .001). Conclusions. Operational MMLs are associated with reductions in opioid positivity among 21- to 40-year-old fatally injured drivers and may reduce opioid use and overdose. PMID:27631755

    Naloxone administration is an important component of resuscitation attempts by emergency medical services (EMS) for opioid drug overdoses. However, EMS providers must first recognize the possibility of opioid overdose in clinical encounters. As part of a public health response to an outbreak of opioid overdoses in Rhode Island, we examined missed opportunities for naloxone administration and factors potentially influencing EMS providers' decision to administer naloxone. We reviewed medical examiner files on all individuals who died of an opioid-related drug overdose in Rhode Island from January 1, 2012 through March 31, 2014, underwent attempted resuscitation by EMS providers, and had records available to assess for naloxone administration. We evaluated whether these individuals received naloxone as part of their resuscitation efforts and compared patient and scene characteristics of those who received naloxone to those who did not receive naloxone via chi-square, t-test, and logistic regression analyses. One hundred and twenty-four individuals who underwent attempted EMS resuscitation died due to opioid overdose. Naloxone was administered during EMS resuscitation attempts in 82 (66.1%) of cases. Females were nearly three-fold as likely not to receive naloxone as males (OR 2.9; 95% CI 1.2-7.0; p-value 0.02). Additionally, patients without signs of potential drug abuse also had a greater than three-fold odds of not receiving naloxone (OR 3.3; 95% CI 1.2-9.2; p-value 0.02). Older individuals, particularly those over age 50, were more likely not to receive naloxone than victims younger than age 30 (OR 4.8; 95% CI 1.3-17.4; p-value 0.02). Women, older individuals, and those patients without clear signs of illicit drug abuse, were less likely to receive naloxone in EMS resuscitation attempts. Heightened clinical suspicion for opioid overdose is important given the recent increase in overdoses among patients due to prescription opioids.

    Objectives. We estimated national and state trends in opioid agonist medication-assisted treatment (OA-MAT) need and capacity to identify gaps and inform policy decisions. Methods. We generated national and state rates of past-year opioid abuse or dependence, maximum potential buprenorphine treatment capacity, number of patients receiving methadone from opioid treatment programs (OTPs), and the percentage of OTPs operating at 80% capacity or more using Substance Abuse and Mental Health Services Administration data. Results. Nationally, in 2012, the rate of opioid abuse or dependence was 891.8 per 100 000 people aged 12 years or older compared with national rates of maximum potential buprenorphine treatment capacity and patients receiving methadone in OTPs of, respectively, 420.3 and 119.9. Among states and the District of Columbia, 96% had opioid abuse or dependence rates higher than their buprenorphine treatment capacity rates; 37% had a gap of at least 5 per 1000 people. Thirty-eight states (77.6%) reported at least 75% of their OTPs were operating at 80% capacity or more. Conclusions. Significant gaps between treatment need and capacity exist at the state and national levels. Strategies to increase the number of OA-MAT providers are needed. PMID:26066931

    Shortly after the Wenchuan earthquake, the administrative leaders of West China Hospital accurately defined the role of the hospital during the medical rescue work as the treatment center for seriously wounded people, the support center for local hospitals and clinics in the disaster areas in Sichuan Province, and the logistics support center for medical teams from other provinces. Integrated leadership of management and efficient multidepartment co-ordination and co-operation were emphasized. The hospital was immediately transformed from regular mode into a double-track emergency mode. Scientific allocation and dispatch of resources were ensured to meet the changing demand from all levels of rescue work. Three stages were defined based on the conditions of wounded people delivered to the hospital, with different main focuses for each stage. Because of the multidisciplinary co-operation and concerted efforts of a large number of experts from other provinces and countries, an effective and efficient medical rescue service was offered to all wounded people. Until 2 June 2008, 2618 injured people from the disaster area have been treated, of whom 1751 were admitted to the inpatient department, 1135 were seriously wounded, 127 were admitted into the intensive care unit, 1239 underwent surgery, and 77 were treated with haemodialysis. There was an inpatient mortality less than 0.7%. Moreover, even during such a period, routine medical service was offered to patients other than people wounded in the disaster.

    Full Text Available Over the past century, there were more than 40 earthquakes greater than 7 magnitude occurred worldwide, 10 of which in China, which killed 600 thousand people accounting for 53% of global earthquake deaths. On May 12, 2008, an 8.0-magnitude earthquake occurred in Wenchuan, Sichuan Province, causing 69000 deaths, 18000 missings, and 370000 injuries. Among 10 thousand severe injuries, most were traumatic injuries, 74% of which were fracture. On April 14, 2010, a 7.1-magnitude earthquake occurred in Yushu, Qinghai Province. There were 2698 deaths, 270 missings and 11000 injuries. Among 3100 severe injuries, fracture accounted for 58.4%. After each earthquake, the Chinese Army Medical Services took actions and made quick response according to the law. They sent out elites with efficient command and scientific organization, fully participating in the medical rescue operations. After Wenchuan earthquake, 397 mobile medical service units and 7061 health workers were sent out. A total of 69000 people were treated, and 22000 cases of surgeries were performed. After Yushu earthquake, a total of 25 mobile medical service units and 2025 health workers were sent. They performed 1635 cases of surgeries with a miracle of "zero death" in mass earthquake casualties and altitude diseases in cold highlands. After each earthquake, injuries cured within 1 week accounted for 60% of the total, and patients evacuated accounted for 80% of the total, which owed to the effective first aid in site of Chinese Army Medical Service. They effectively played the role as the main force, making significant contributions for the final victory of earthquake relief. From the practice of medical rescue revelation after the two earthquakes, what Chinese Army Medical Services Services learned are: firstly, the theory of medical relief should be innovated; secondly, military and civilian organizations should be coordinated; thirdly, professional rescue force should be strengthened

    Opioid use and overdose rates have risen to epidemic levels in the United States during the past decade. Fortunately, there are effective medications (ie, methadone, buprenorphine, and oral and injectable naltrexone) available for the treatment of opioid addiction. Each of these medications is approved for use in conjunction with psychosocial treatment; however, there is a dearth of empirical research on the optimal psychosocial interventions to use with these medications. In this systematic review, we outline and discuss the findings of 3 prominent prior reviews and 27 recent publications of empirical studies on this topic. The most widely studied psychosocial interventions examined in conjunction with medications for opioid addiction were contingency management and cognitive behavioral therapy, with the majority focusing on methadone treatment. The results generally support the efficacy of providing psychosocial interventions in combination with medications to treat opioid addictions, although the incremental utility varied across studies, outcomes, medications, and interventions. The review highlights significant gaps in the literature and provides areas for future research. Given the enormity of the current opioid problem in the United States, it is critical to gain a better understanding of the most effective ways to deliver psychosocial treatments in conjunction with these medications to improve the health and well-being of individuals suffering from opioid addiction.

    Chronic pain is an international health issue of immense importance that is influenced by both physical and psychological factors. Opioids are useful in treating chronic pain but have accompanying complications. It is important for clinicians to understand the basics of opioid pharmacology, the benefits and adverse effects of opioids, and related problematic issues of tolerance, dependence, and opioid-induced hyperalgesia. In this article, the role of psychiatric comorbidity and the use of validated assessment tools to identify individuals who are at the greatest risk for opioid misuse are discussed. Additionally, interventional treatment strategies for patients with chronic pain who are at risk for opioid misuse are presented. Specific behavioral interventions designed to improve adherence with prescription opioids among persons treated for chronic pain, such as frequent monitoring, periodic urine screens, opioid therapy agreements, opioid checklists, and motivational counseling, are also reviewed. Use of state-sponsored prescription drug monitoring programs is also encouraged. Areas requiring additional investigation are identified, and the future role of abuse-deterrent opioids and innovative technology in addressing issues of opioid therapy and pain are presented.

    Prescription opioid abuse and misuse is a serious and growing public health issue. While the most common form of abuse is swallowing intact tablets/capsules, some abusers manipulate, or tamper with, these medications by altering the dosage form to allow for non-oral routes of administration (e.g., injection, inhalation) in order to achieve more rapid or enhanced psychoactive effects. Because administration of opioids via non-oral routes results in greater systemic availability and more rapid central nervous system penetration, we hypothesized that death and major medical outcomes occur more frequently with non-oral routes compared to oral route alone. This retrospective cohort study analyzed data from the Researched Abuse, Diversion and Addiction-Related Surveillance (RADARS) System Poison Center Program to investigate relative risk of prescription opioid abuse via oral and non-oral routes. While the oral route was the most commonly reported route of abuse (64.0%), non-oral routes were reported in 14.6% exposures and unknown routes in 21.4% exposures. The relative risk of an exposure resulting in death or major effect was 2.43 (95% CI 1.97, 2.99) if non-oral routes were reported compared to exposures involving oral route only. Analysis of acute health events recorded by poison centers indicates that death or major effects are twice as likely to occur with intentional abuse of prescription opioids via non-oral routes of administration than ingestion alone. Effective interventions to prevent abuse via non-oral routes of solid dosage forms of prescription opioids, such as abuse-deterrent formulations could have a significant public health impact.

    Despite the established effectiveness of pharmacotherapies for treating opioid use disorders, implementation of medications for addiction treatment (MAT) by specialty treatment programs is limited. This research examined relationships between organizational factors and the program-level implementation of MAT, with attention paid to specific sources of funding, organizational structure, and workforce resources. Face-to-face structured interviews were conducted in 2008 to 2009 with administrators of 154 community-based treatment programs affiliated with the National Institute on Drug Abuse's Clinical Trials Network; none of these programs exclusively dispensed methadone without offering other levels of care. Implementation of MAT was measured by summing the percentages of opioid patients receiving buprenorphine maintenance, methadone maintenance, and tablet naltrexone. Financial factors included the percentages of revenues received from Medicaid, private insurance, criminal justice, the Federal block grant, state government, and county government. Organizational structure and workforce characteristics were also measured. Implementation of MAT for opioid use disorders was low. Greater reliance on Medicaid was positively associated with implementation after controlling for organizational structure and workforce measures, whereas the association for reliance on criminal justice revenues was negative. The implementation of MAT for opioid use disorders by specialty addiction treatment programs may be facilitated by Medicaid but may be impeded by reliance on funding from the criminal justice system. These findings point to the need for additional research that considers the impact of organizational dependence on different types of funding on patterns of addiction treatment practice.

    Reliable access to opioid medication is critical to delivering effective pain management, adequate treatment of opioid dependence, and quality palliative care. However, more than 80% of the world population is estimated to be inadequately treated for pain because of difficulties in accessing opioids. Although barriers to opioid access are primarily associated with restrictive laws, regulations, and licensing requirements, a key problem that significantly limits opioid access relates to policy constraints. To identify and explore policy barriers to opioid access in 12 Eastern and Central European countries involved in the Access to Opioid Medication in Europe project, funded by the European Community's Seventh Framework (FP7/2007-2013, no. 222994) Programme. A systematic content analysis of texts retrieved from documents (e.g., protocols of national problem analyses, strategic planning worksheets, and executive summaries) compiled, reviewed, approved, and submitted by either the Access to Opioid Medication in Europe consortium or the national country teams (comprising experts in pain management, harm reduction, and palliative care) between September 2011 and April 2014 was performed. Twenty-five policy barriers were identified (e.g., economic crisis, bureaucratic issues, lack of training initiatives, stigma, and discrimination), classified under four predetermined categories (financial/economic aspects and governmental support, formularies, education and training, and societal attitudes). Key barriers related to issues of funding allocation, affordability, knowledge, and fears associated with opioids. Reducing barriers and improving access to opioids require policy reform at the governmental level with a set of action plans being formulated and concurrently implemented and aimed at different levels of social, education, and economic policy change.

    Aspirin is the mainstay in prophylaxis of cardiovascular diseases. Impaired aspirin antiplatelet effects are associated with enhanced incidence of cardiovascular events. Comedication with non-opioid analgesic drugs has been described to interfere with aspirin,resulting in impaired aspirin antiplatelet effects. Additionally,nonopioid analgesic medication has been shown to enhance the risk of cardiovascular events and death. Pain is very frequent and many patients rely on analgesic drugs to control pain. Therefore effective analgesic options without increased risk of cardiovascular events are desirable. This review focuses on commonly used nonopioid analgesics,interactions with aspirin medication and impact on cardiovascular risk.

    In the interest of preservation of high degree of objectivity of information about students' educational outcomes, a system of assessment needs to meet criteria of appropriate reliability and validity. Analysis of reliability and validity of the system of assessment of students' educational outcomes for courses followed by an examination and covered by a curriculum in Medical Rescue at Medical University of Warsaw (MU W). A retrospective study enrolling a group of 421 students of eight subsequent full education cycles. Detailed data concerning grades for fourteen courses followed by an examination in the entire course of studies were collected. Reliability (Cronbach's alpha coefficient) and criteria validity (Spearman's rank correlation) were assessed. Internal consistency was estimated using a multiple regression model. The levels of assessment reliability for the general university, pre-clinical, and clinical scopes amounted to alpha: 0.42, 0.53, and 0.70, respectively. The strongest positive correlations between the results of pre-clinical and clinical trainings were found for the Anatomy course (r ≈ 0.30). Only in the case of the Pharmacology course it was found that students' achievements in this field were significantly correlated with all other courses of clinical training. The influence of educational outcomes in particular areas of clinical training on the final grade for the entire course of studies was diverse (β regression between 0.04 and 0.11). While the Pharmacology course had the strongest impact on final results, the Surgery course had the least influence on students' final grades (β = 0.04). 1. Sufficient reliability of the system of assessment of educational outcomes in Medical Rescue showed good precision and repeatability of assessment. 2. A low level of validity was caused by a failure to keep the appropriateness of the assessment of educational outcomes in several clinical courses. 3.

    Delirium is an important problem in hospitalized cancer patients. The objective of this study was to determine whether exposure to corticosteroids, benzodiazepines, or opioids predicted delirium. A prospective cohort study was conducted in an oncology/internal medicine population. Patients were assessed continuously for the presence of delirium until they were discharged by using the Nursing Delirium Screening Scale (Nu-DESC). Follow-up for outcome began after incident delirium. The primary outcome was the presence of a delirium event, which was defined as a Nu-DESC score >1. Strengths of associations of medications with delirium were expressed as odds ratios (ORs) in univariate and multivariate analyses. In total, 114 patients (1823 patient-days) met the inclusion criteria for the study. The mean follow-up from incident delirium was 16 days. The mean number of delirium events by patient was 6 (total number, 667 delirium events). Analysis by day on several occasions revealed significant associations between opioids and delirium. Corticosteroids and benzodiazepines were not associated significantly with an increased risk of delirium on any given day. Analysis by patient using generalized estimating equation (GEE) models showed an increased risk of delirium on any day of follow-up associated with opioid exposure in univariate analysis (OR of 1.70; Phospitalization was associated significantly with an increased longitudinal risk of delirium.

    Background Variation in the CYP2D6 gene may affect response to opioids in both poor and ultrarapid metabolizers, but data demonstrating such associations have been mixed, and the impact of variants on toxicity-related symptoms (e.g., nausea) is unclear. Therefore, we examined the association between CYP2D6 phenotype and poor pain control or other adverse symptoms related to the use of opioids in a sample of primary care patients. Materials and methods We identified all patients in the Mayo Clinic RIGHT Protocol who were prescribed an opioid medication between July 01, 2013 and June 30, 2015, and categorized patients into three phenotypes: poor, intermediate to extensive, or ultrarapid CYP2D6 metabolizers. We reviewed the electronic health record of these patients for indications of poor pain control or adverse symptoms related to medication use. Associations between phenotype and outcomes were assessed using Chi-square tests and logistic regression. Results Overall, 257 (25% of RIGHT Protocol participants) patients received at least one opioid prescription; of these, 40 (15%) were poor metabolizers, 146 (57%) were intermediate to extensive metabolizers, and 71 (28%) were ultrarapid metabolizers. We removed patients that were prescribed a CYP2D6 inhibitor medication (n=38). After adjusting for age and sex, patients with a poor or ultrarapid phenotype were 2.7 times more likely to experience either poor pain control or an adverse symptom related to the prescription compared to patients with an intermediate to extensive phenotype (odds ratio: 2.68; 95% CI: 1.39, 5.17; p=0.003). Conclusion Our results suggest that >30% of patients with a poor or ultrarapid CYP2D6 phenotype may experience an adverse outcome after being prescribed codeine, tramadol, oxycodone, or hydrocodone. These medications are frequently prescribed for pain relief, and ~39% of the US population is expected to carry one of these phenotypes, suggesting that the population-level impact of these gene

    To get a more comprehensive understanding of the clinical characteristics of pediatric victims in earthquake and to summarize the experience of medical rescue. The clinical information was collected from the pediatric victims who were admitted to West China Hospital, Sichuan University following the Lushan earthquake in 2013 and Wenchuan earthquake in 2008. The clinical data were compared between the pediatric victims in the two earthquakes. Thirty-four children under 14 years of age, who were injured in the Lushan earthquake, were admitted to the West China Hospital before April 30, 2013. Compared with the data in the Wenchuan earthquake, the mean age of the pediatric victims in the Lushan earthquake was significantly lower (Pearthquake to hospitalization was significantly shorter (Pearthquake, 67.6% of the injured children had variable limb fractures; traumatic brain injury was found in 29.4% of hospitalized children, versus 9.5% in the Wenchuan earthquake (Pearthquake than in the Wenchuan earthquake. But these cases recovered well, which was possibly due to timely on-site rescue and transfer and multi-sector, multi-institution, and multidisciplinary cooperation.

    Benzodiazepine-like drugs (z-hypnotics) are the most commonly used drugs for treatment of insomnia in Norway. Z-hypnotics are recommended for short-term treatment not exceeding 4 weeks. We aimed to study the use of z-hypnotics in the adult population in Norway with focus on recurrent use in new users, treatment intensity and co-medication with benzodiazepines and opioids in long-term users. Data were obtained from the Norwegian Prescription Database. New users in 2009 were followed through 2013. Recurrent z-hypnotic use was defined as new fillings at least once in each of the four 365-day follow-up periods. Age groups of 18-39, 40-64 and 65+ years were analysed separately for men and women. In 2013, 354,571 (8.9%) of the population filled at least one prescription of z-hypnotics and the prevalence was relatively stable over time. Among the 92,911 new users of z-hypnotics in 2009, 13,996 (16.8%) received z-hypnotics all four 365-day periods of follow-up. In these long-term recurrent users, the treatment intensity was high already the second year, with mean annual amounts of 199 and 169 DDDs per patient in men and women, respectively. The interquartile differences were greatest in the youngest age group. 27.9% of the long-term recurrent users of z-hypnotics used benzodiazepines the fourth year and 33.9% used opioids. The proportions with co-medication increased with level of z-hypnotic treatment intensity. Overall, many z-hypnotic users had medicines dispensed for longer periods than recommended, and co-medications with drugs that may reinforce the central depressing and intoxicating effects were common.

    Full Text Available Background: Due to the growing use of various types of industrial and agricultural machinery, occupational accidents are among the most serious ones and quite frequently result in the permanent posttraumatic disability of the injured person. In Poland, a replantation service has been operating since 2010. Each day, one out of six centres provides emergency replantation service accepting amputation calls from across the country. Patients qualified for replantation often need to be transported from places located even several hundred kilometres from the target hospital. Material and Methods: The analysis covered 174 Helicopter Emergency Medical Service (HEMS missions and 112 interhospital transports. The data were obtained as a result of a retrospective analysis of the air and medical documentation of 23 460 missions carried out by the Polish Medical Air Rescue (Samodzielny Publiczny Zakład Opieki Zdrowotnej Lotnicze Pogotowie Ratunkowe – SP ZOZ LPR aircrafts in the years 2011–2013. Results: In the period under study, the Polish Medical Air Rescue helicopters dressed 135 patients with upper extremity amputations at the scene and transported them to hospitals as part of HEMS missions. At the same time, SP ZOZ LPR aircrafts made 102 interhospital transports. Ninety patients were qualified for treatment in replantation service centres. The average air transport time was 76 min, while the total transport time was 172.3 min. With transport exceeding 300 km, the average time advantage over the ground transport was approximately 1.5 h. Conclusions: In justified cases, the use of helicopters and airplanes is an optimal method of transporting patients with the major trauma to upper extremities. Med. Pr. 2014;65(6:765–776

    Diversion (i.e. selling or giving away) of opioid maintenance treatment (OMT) medications is a challenge that concerns many units providing OMT worldwide and tools for prevention are needed. The object of this study was to examine the prevalence and predictors for diversion of the OMT medications buprenorphine-naloxone (BNX) and methadone (MET) among Finnish OMT patients. A cross-sectional study was conducted among all Finnish OMT patients of whom 60% (n=1508) participated. The data were collected by anonymous questionnaires distributed through all OMT units in Finland. To evaluate predictors for diversion, we used binominal regression analysis with unadjusted and adjusted ORs. Selling and/or giving away of OMT medication was used as a dependent variable and explanatory variables were gender, age, duration of OMT, type of OMT medication and dose, dispensation method of OMT medication, place of residence and intravenous use of any intoxicating drugs during the past six months. Of all 1508 respondents, 7% (n=100) had sold and 12% (n=169) had given their OMT medication to others, 57% for money and 23% in exchange for other drugs. In multivariate analysis, predictors associated with diversion were BNX as OMT medication (OR 2.76, 95% CI 1.76-4.33), low (OMT (OR 1.01, 95% CI 1.01-1.02). Age, place of residence or unsupervised pharmacy distribution of BNX were not associated with diversion. In order to reduce diversion, more interventions are needed to support patients to stop concurrent substance abuse. Increasing control measures, for example, increased supervision, are unlikely to prevent diversion. Given that sub-optimal dosing of BNX increases the risk of diversion, more attention should be paid to providing patients with an optimal medical dose. Copyright © 2015 Elsevier B.V.

    The aim of this study was to examine trends and associated factors in the prescription of opioid analgesics, nonopioid analgesics, opioid and nonopioid analgesic combinations, and no analgesics by emergency physicians for nontraumatic dental condition (NTDC)-related visits. Our secondary aim was to investigate whether race/ethnicity is a possible predictor of receiving a prescription for either type of medication for NTDC visits in emergency departments (EDs) after adjustment for potential covariates. We analyzed data from the National Hospital Ambulatory Medical Care Survey for 1997-2000 and 2003-2007, and used multinomial multivariate logistic regression to estimate the probability of receiving a prescription for opioid analgesics, nonopioid analgesics, or a combination of both, compared with receiving no analgesics for NTDC-related visits. During 1997-2000 and 2003-2007, prescription of opioid analgesics and combinations of opioid and nonopioid analgesics increased, and that of no analgesics decreased over time. The prescription rates for opioid analgesics, nonopioid analgesics, opioid and nonopioid analgesic combinations, and no analgesics for NTDC-related visits in EDs were 43 percent, 20 percent, 12 percent, and 25 percent, respectively. Majority of patients categorized as having severe pain received prescriptions for opioids for NTDC-related visits in EDs. After adjusting for covariates, patients with self-reported dental reasons for visit and severe pain had a significantly higher probability of receiving prescriptions for opioid analgesics and opioid and nonopioid analgesic combinations. Prescription of opioid analgesics increased over time. ED physicians were more likely to prescribe opioid analgesics and opioid and nonopioid analgesic combinations for NTDC-related visits with reported severe pain. © 2014 American Association of Public Health Dentistry.

    In 2014 Health Canada replaced the Marihuana for Medical Access Regulations (MMAR) with the Marihuana for Medical Purposes Regulations (MMPR). One of the primary changes in the new program has been to move from a single Licensed Producer (LP) of cannabis to multiple Licensed Producers. This is the first comprehensive survey of patients enrolled in the MMPR. Patients registered to purchase cannabis from Tilray, a federally authorized Licenced Producer (LP) within the MMPR, were invited to complete an online survey consisting of 107 questions on demographics, patterns of use, and cannabis substitution effect. The survey was completed by 271 respondents. Cannabis is perceived to be an effective treatment for diverse conditions, with pain and mental health the most prominent. Findings include high self-reported use of cannabis as a substitute for prescription drugs (63%), particularly pharmaceutical opioids (30%), benzodiazepines (16%), and antidepressants (12%). Patients also reported substituting cannabis for alcohol (25%), cigarettes/tobacco (12%), and illicit drugs (3%). A significant percentage of patients (42%) reported accessing cannabis from illegal/unregulated sources in addition to access via LPs, and over half (55%) were charged to receive a medical recommendation to use cannabis, with nearly 25% paying $300 or more. The finding that patients report its use as a substitute for prescription drugs supports prior research on medical cannabis users; however, this study is the first to specify the classes of prescription drugs for which cannabis it is used as a substitute, and to match this substitution to specific diagnostic categories. The findings that some authorized patients purchase cannabis from unregulated sources and that a significant percentage of patients were charged for medical cannabis recommendations highlight ongoing policy challenges for this federal program.

    To calculate trends in adult average days' supply for six commonly prescribed opioids: hydrocodone, hydromorphone, morphine, oxycodone, oxymorphone, and tapentadol to assess whether physicians changed prescribing practices at the time of the intensifying epidemic. We used 2005-2015 Truven Health MarketScan Commercial Claims and Encounters data to measure trends in opioid average days' supply among commercially insured individuals and 2005-2014 MarketScan Multi-State Medicaid data to measure trends in opioid average days' supply among Medicaid beneficiaries. For Medicaid, we found an increase in days' supply for all drugs except morphine. The largest percentage increase was for oxycodone, which increased 4.5days (37%). Opioid days' supply for individuals with commercial insurance exhibited similar but steeper trends. The largest increase was also for oxycodone, which increased 6days (56%). Between 2013 and 2015, when the opioid epidemic had begun to be widely publicized, there was no decline in the median days supplied for any of the opioids. Our results find that days' supply of opioids are increasing despite public health campaigns and media attention on the risks of opioid prescribing. More effective interventions to curb opioid prescribing are needed to reverse these trends. Published by Elsevier Ltd.

    Full Text Available Objective. To identify factors associated with opioid use during pregnancy and to compare perinatal morbidity, mortality, and healthcare costs between opioid users and nonusers. Methods. We conducted a cross-sectional analysis of pregnancy-related discharges from 1998 to 2009 using the largest publicly available all-payer inpatient database in the United States. We scanned ICD-9-CM codes for opioid use and perinatal outcomes. Costs of care were estimated from hospital charges. Survey logistic regression was used to assess the association between maternal opioid use and each outcome; generalized linear modeling was used to compare hospitalization costs by opioid use status. Results. Women who used opioids during pregnancy experienced higher rates of depression, anxiety, and chronic medical conditions. After adjusting for confounders, opioid use was associated with increased odds of threatened preterm labor, early onset delivery, poor fetal growth, and stillbirth. Users were four times as likely to have a prolonged hospital stay and were almost four times more likely to die before discharge. The mean per-hospitalization cost of a woman who used opioids during pregnancy was $5,616 (95% CI: $5,166–$6,067, compared to $4,084 (95% CI: $4,002–$4,166 for nonusers. Conclusion. Opioid use during pregnancy is associated with adverse perinatal outcomes and increased healthcare costs.

    We established the Terminal Care Study Group, consisting of physicians, pharmacists, and nurses, in September 2001, and developed the group into the Palliative Care Team. We have surveyed the state of concomitant medications immediately before and at the beginning of opioid usage (except injections) to assess the role of the Palliative Care Team. The survey period was 3 years from October 1, 2002 to September 30, 2005. While the frequency of the prescription of non-steroidal anti-inflammatory drugs (NSAIDs), laxatives, or antiemetics before the beginning of opioid administration did not differ significantly among the 3 periods, that at the beginning of opioid administration increased significantly in 2003 compared with 2002, and increased further in 2004. Many of the drugs used were those that were recommended in our cancer pain management program. Thus, the activities of the Palliative Care Team are considered to have led to proper measures for the control of the major adverse effects of opioids such as constipation and nausea/vomiting in addition to pain control in accordance with the WHO's pain ladder, and also contributed to improvements of the patients' QOL.

  5. Are peripheral opioid antagonists the solution to opioid side effects?

    LENUS (Irish Health Repository)

    Bates, John J

    2012-02-03

    Opioid medication is the mainstay of therapy for severe acute and chronic pain. Unfortunately, the side effects of these medications can affect patient comfort and safety, thus limiting their proven therapeutic potential. Whereas the main analgesic effects of opioids are centrally mediated, many of the common side effects are mediated via peripheral receptors. Novel peripheral opioid antagonists have been recently introduced that can block the peripheral actions of opioids without affecting centrally mediated analgesia. We review the clinical and experimental evidence of their efficacy in ameliorating opioid side effects and consider what further information might be useful in defining their role. IMPLICATIONS: The major analgesic effects of opioid medication are mediated within the brain and spinal cord. Many of the side effects of opioids are caused by activation of receptors outside these areas. Recently developed peripherally restricted opioid antagonists have the ability to block many opioid side effects without affecting analgesia.

    To examine whether prenatal exposure to opioid agonist medication is associated with visual selective attention and general attention problems in early childhood. Twenty-two children (mean age = 52.17 months, SD = 1.81) prenatally exposed to methadone, 9 children (mean age = 52.41 months, SD = 1.42) prenatally exposed to buprenorphine and 25 nonexposed comparison children (mean age = 51.44 months, SD = 1.31) were tested. Visual selective attention was measured with a Tobii 1750 Eye Tracker using a spatial negative priming paradigm. Attention problems were measured using the Child Behavior Checklist. The comparison group demonstrated a larger spatial negative priming effect (mean = 23.50, SD = 45.50) than the exposed group [mean = -6.84, SD = 86.39, F(1,50) = 5.91, p = 0.019, η(2) = 0.11]. No difference in reported attention problems was found [F(1,51) = 1.63, p = 0.21, η(2) = 0.03]. Neonatal abstinence syndrome and prenatal exposure to marijuana were found to predict slower saccade latencies in the exposed group (b = 54.55, SE = 23.56, p = 0.03 and b = 88.86, SE = 32.07, p = 0.01, respectively). Although exposed children did not appear to have attention deficits in daily life, lower performance on the SNP task indicates subtle alteration in the attention system. © 2014 S. Karger AG, Basel.

    The aim of the study was to describe the use of prescribed opioid analgesics for noncancer pain and the degree of possible concurrent co-medication with benzodiazepines to women in Norway before, during, and after pregnancy. This was a population-based cohort study based on linkage of two nationwide registries: the Medical Birth Registry of Norway, and the Norwegian Prescription Database. Prescribed opioid analgesics and benzodiazepines issued to women 3 months prior to, during, and 3 months after pregnancies were identified. The study population consisted of 194,937 singleton pregnancies beginning in March 2004 or later and ending before January 2009. About 6% of the women were dispensed opioid analgesics before, during, or after pregnancy. Almost all these women received weak opioids (99%) with short-acting codeine in combination with paracetamol (acetaminophen) as the most frequently dispensed drug. The dispensing of codeine was reduced from 24/1,000 women before pregnancy to 10/1,000 in the last trimester, increasing to 17/1,000 during the breastfeeding period. Most women were dispensed codeine once, and treatment was of short duration (about 1 week). A small group of women (n = 271) were dispensed opioids in all trimesters. Increasing benzodiazepine use was observed as the number of opioid prescriptions increased. The use of opioid analgesics in pregnant women in Norway was dominated by treatment of short duration of the weak opioid codeine. As pregnancy proceeded, opioid use was reduced. However, the increase in opioid use during the nursing period has the potential for serious adverse effects.

  9. Subterranean medicine: an inquiry into underground medical treatment protocols in cave rescue situations in national parks in the United States.

    2000-01-01

    Caving and spelunking have become increasingly popular over the years, with hundreds of thousands of amateur spelunkers across the country visiting caves. National parks in the United States offer hundreds of caves for all levels of spelunkers and, in fact, many national parks boast caves as either their main or major attraction. In an effort to increase visitor safety and establish subterranean medical treatment protocols, we began an investigation into cave rescue, medical protocols, previously published recommendations concerning cave safety, and visitor and rescue statistics in the national parks. Our inquiry provided little guidance from either the literature or the present US National Parks database for treating underground injuries. However, 2 predominant trends did appear. First, despite the nearly 2 million visitors to the caves in the 14 parks surveyed, there were only about 200 total calls for medical care. The vast number of those calls were for minor injuries. Second, no strict evidence-based treatment protocols for underground injuries exist, probably because they are not feasible. A caving incident database for the national parks would facilitate suggestions for preventative measures for the minor injuries and would help catalog the creative solutions for the rare serious subterranean medical incident.

    There has been a well documented increase in the use and abuse of prescription opioids and heroin in the United States and other parts of the world. There has also been an increasing focus to increase access to the use of medications (methadone, buprenorphine, Naltrexone/Vivitrol) for opioid addicted individuals under legal supervision. As policymakers engage in strategic initiatives to better prevent and effectively treat chronic opioid addiction, both in the United States and other countries, there are a number of unintended consequences, complicating how best to increase access to effective treatment.

    crisis de DI en pacientes oncológicos que tienen controlado su dolor basal con dosis altas de opioides. Las dosis de CFOT pueden considerarase como bajas en relación a las utilizadas para su dolor basal. Su administración y titulación es sencilla, aunque el paciente requiere de una educación previa a su uso.The management of breakthrough pain in cancer patients treated with high doses of opiates raises particular problems, such as the election of the drug to be used, the appropriate dosage and the route of administration. No clear guidelines on this issue are found in the medical literature, so each service decides its own particular way of acting. In this paper we review the cases dealt with over a one-year period in terms of the use of high doses of opiates in cancer patients taken care of in 2003 and treated with opiates. Objectives: -To study the group of patients treated with high doses of opiates. -To use OTFC as rescue drug for breakthrough pain events. -To analyze side and toxic effects. -To determine the preferences of the patients. Material and methods: A population of 280 patients with advanced cancer, 25 of which were receiving high doses of opiates. In these patients, breakthrough pain crises were managed with OTFC, starting with 400 micrograms. The satisfaction questionnaire proposed by Kornick was used. Results: -Easy adherence to treatment. -Average effective dose of OTFC: 600 micrograms, median of 627. -Dose titration on the second day. -Seventeen patients preferred OTFC, 6 preferred oral morphine and 2 were indifferent. Conclusions: Easy use of OTFC for the management of breakthrough pain, requiring low doses compared to the total daily dose of the patient. Patient education is required before its administration.

    This study aimed to describe the lived experiences of participating in a medication-assisted treatment as disclosed by individuals with opioid dependence. Eleven narrative interviews were conducted and subjected to qualitative content analysis. The experiences of participating in the programme were described as a process from resistance to existence. The participants seized the chance to claim a life lived with dignity, struggled with hidden challenges, and eventually were freed from their pasts and were grateful for an existence with dignity. The recovery process was a long-term commitment and participants asked for a more individual and flexible process based on personal needs and values.

  17. Ethical Tensions in the Pain Management of an End-Stage Cancer Patient with Evidence of Opioid Medication Diversion.

    2016-06-01

    At the end of life, pain management is commonly a fundamental part of the treatment plan for patients where curative measures are no longer possible. However, the increased recognition of opioid diversion for secondary gain coupled with efforts to treat patients in the home environment towards the end of life creates the potential for ethical dilemmas in the palliative care management of terminal patients in need of continuous pain management. We present the case of an end-stage patient with rectal cancer who required a continuous residential narcotic infusion of fentanyl for pain control due to metastatic disease. His functional status was such that he had poor oral intake and ability to perform other activities of daily living, but was able to live at home with health agency nursing care. The patient presented to this institution with a highly suspect history of having lost his fentanyl infusion in a residential accident and asking for a refill to continue home therapy. The treating physicians had concerns of diversion of the infusion medication by caregivers and were reluctant to continue the therapeutic relationship with the patient. This case exemplifies the tension that can exist between wanting to continue with palliative care management of an end-stage patient and the fear of providers when confronted by evidence of potential diversion of opioid analgesic medications. We elucidate how an ethical framework based on a combination of virtue and narrative/relationship theories with reference to proportionality can guide physicians to a pragmatic resolution of these difficult situations.

  19. Opioid analgesics: does potency matter?

    Science.gov (United States)

    Passik, Steven D; Webster, Lynn

    2014-01-01

    Prescription opioid analgesics with a wide range of potencies are currently used for the treatment of chronic pain. Yet understanding the clinical relevance and therapeutic consequences of opioid potency remains ill defined. Both patients and clinicians alike have misperceptions about opioid potency, expecting that less-potent opioids will be less effective or fearing that more-potent opioids are more dangerous or more likely to be abused. In this review, common myths about the potency of opioid analgesics will be discussed. Clinicians should understand that pharmacologic potency per se does not necessarily imply more effective analgesia or higher abuse liability. Published dose conversion tables may not accurately calculate the dose for effective and safe rotation from one opioid to another in patients receiving long-term opioid therapy because they are based on limited data that may not apply to chronic pain. Differences in pharmacologic potency are largely accounted for by the actual doses prescribed, according to individualized patient need. Factors for achieving effective analgesia and reducing the risks involved with opioid use include careful medication selection based on patient characteristics, appropriate dosing titration and opioid rotation practices, knowledge of product formulation characteristics (eg, extended release, immediate release, and tamper-resistant features), and an awareness of differences in opioid pharmacokinetics and metabolism. Clinicians should remain vigilant in monitoring patients on any opioid medication, regardless of classification along the opioid potency continuum.

  1. Review of naloxone safety for opioid overdose: practical considerations for new technology and expanded public access.

    Science.gov (United States)

    Wermeling, Daniel P

    2015-02-01

    Opioid overdose and mortality have increased at an alarming rate prompting new public health initiatives to reduce drug poisoning. One initiative is to expand access to the opioid antidote naloxone. Naloxone has a long history of safe and effective use by organized healthcare systems and providers in the treatment of opioid overdose by paramedics/emergency medicine technicians, emergency medicine physicians and anesthesiologists. The safety of naloxone in a prehospital setting administered by nonhealthcare professionals has not been formally established but will likely parallel medically supervised experiences. Naloxone dose and route of administration can produce variable intensity of potential adverse reactions and opioid withdrawal symptoms: intravenous administration and higher doses produce more adverse events and more severe withdrawal symptoms in those individuals who are opioid dependent. More serious adverse reactions after naloxone administration occur rarely and may be confounded by the effects of other co-intoxicants and the effects of prolonged hypoxia. One component of the new opioid harm reduction initiative is to expand naloxone access to high-risk individuals (addicts, abusers, or patients taking high-dose or extended-release opioids for pain) and their close family or household contacts. Patients or their close contacts receive a naloxone prescription to have the medication on their person or in the home for use during an emergency. Contacts are trained on overdose recognition, rescue breathing and administration of naloxone by intramuscular injection or nasal spraying of the injection prior to the arrival of emergency medical personnel. The safety profile of naloxone in traditional medical use must be considered in this new context of outpatient prescribing, dispensing and treatment of overdose prior to paramedic arrival. New naloxone delivery products are being developed for this prehospital application of naloxone in treatment of opioid

    Withdrawal of opioid medication in patients with chronic pain has a drop-out and relapse problem. To evaluate if depressive symptoms, anxiety and pain intensity are potential risk factors for drop-out or relapse during the withdrawal process. Further, to assess internal consistency of scales for assessment of these potential risk factors. Twenty-nine patients were included. After 2 years 28 of these were followed-up. Those with depressive symptoms at baseline had a significant risk for drop-out from the withdrawal program (odds ratio 1.37) and relapse into use of opioids at follow-up (odds ratio 1.44). Drop-outs rated depressive symptoms significantly higher before detoxification. Those who relapsed rated significantly higher for pain intensity, depressive symptoms and abstinence prior to withdrawal. All scales had high reliability. To avoid drop-out and relapse clinical practice need to screen for depressive symptoms, pain intensity, and abstinence. This article presents significant reliability of scales useful within dependency centers. They can be used to identify these risk factors for drop-out and relapse, respectively, when initiating the withdrawal process. Taking these risk factors into consideration could improve the outcome of the withdrawal process by preventing drop-out and relapse.

  4. Opioid rotation with extended-release opioids: where should we begin?

    Science.gov (United States)

    Nalamachu, Srinivas

    2012-01-01

    Opioid rotation is a common and necessary clinical practice in the management of chronic non-cancer pain to improve therapeutic efficacy with the lowest opioid dose. When dose escalations fail to achieve adequate analgesia or are associated with intolerable side effects, a trial of a new opioid should be considered. Much of the scientific rationale of opioid rotation is based on the wide interindividual variability in sensitivity to opioid analgesics and the novel patient response observed when introducing an opioid-tolerant patient to a new opioid. This article discusses patient indicators for opioid rotation, the conversion process between opioid medications, and additional practical considerations for increasing the effectiveness of opioid therapy during a trial of a new opioid. A Patient vignette that demonstrates a step-wise approach to opioid rotation is also presented.

    In consideration of rising cost pressure in the German health care system, the usefulness of helicopter emergency medical service (HEMS) in terms of time- and cost-effectiveness is controversially discussed. The aim of the present study was to investigate whether HEMS is associated with significantly decreased arrival and transportation times compared to ground EMS. In a retrospective study, we evaluated 1,548 primary emergency missions for time sensitive diagnoses (multiple trauma, traumatic brain and burn injury, heart-attack, stroke, and pediatric emergency) performed by a German HEMS using the medical database, NADIN, of the German Air Rescue Service. Arrival and transportation times were compared to calculated ground EMS times. HEMS showed significantly reduced arrival times at the scene in case of heart-attack, stroke and pediatric emergencies. In contrast, HEMS and ground EMS showed comparable arrival times in patients with multiple trauma, traumatic brain and burn injury due to an increased flight distance. HEMS showed a significantly decreased transportation time to the closest centre capable of specialist care in all diagnosis groups (pambulance services with significantly decreased transportation times.

    2015-01-01

    The Centers for Disease Control have recently described opioid use and resultant deaths as an epidemic. At this point in time, treating this disease well with medication requires skill and time that are not generally available to primary care doctors in most practice models. Suboptimal treatment has likely contributed to expansion of the epidemic and concerns for unethical practices. At the same time, access to competent treatment is profoundly restricted because few physicians are willing and able to provide it. This "Practice Guideline" was developed to assist in the evaluation and treatment of opioid use disorder, and in the hope that, using this tool, more physicians will be able to provide effective treatment. Although there are existing guidelines for the treatment of opioid use disorder, none have included all of the medications used at present for its treatment. Moreover, few of the existing guidelines address the needs of special populations such as pregnant women, individuals with co-occurring psychiatric disorders, individuals with pain, adolescents, or individuals involved in the criminal justice system. This Practice Guideline was developed using the RAND Corporation (RAND)/University of California, Los Angeles (UCLA) Appropriateness Method (RAM) - a process that combines scientific evidence and clinical knowledge to determine the appropriateness of a set of clinical procedures. The RAM is a deliberate approach encompassing review of existing guidelines, literature reviews, appropriateness ratings, necessity reviews, and document development. For this project, American Society of Addiction Medicine selected an independent committee to oversee guideline development and to assist in writing. American Society of Addiction Medicine's Quality Improvement Council oversaw the selection process for the independent development committee. Recommendations included in the guideline encompass a broad range of topics, starting with the initial evaluation of the

    The purpose of this article is to establish medical recommendations for safe and effective Helicopter Emergency Medical Systems (HEMS) in countries with a dedicated mountain rescue service. A nonsystematic search was undertaken and a consensus among members of International Commission for Mountain Emergency Medicine (ICAR Medcom) was reached. For the severely injured or ill patient, survival depends on approach time and quality of medical treatment by high-level providers. Helicopters can provide significant shortening of the times involved in mountain rescue. Safety is of utmost importance and everything possible should be done to minimize risk. Even in the mountainous environment, the patient should be reached as quickly as possible (optimallymountainous areas. The nearest qualified HEMS team to the incident site, regardless of administrative boundaries, should be dispatched. The 'air rescue optimal crew' concept with its flexibility and adaptability of crewmembers ensures that all HEMS tasks can be performed. The helicopter and all equipment should be appropriate for the conditions and specific for mountain related emergencies. These recommendations, agreed by ICAR Medcom, establish recommendations for safe and effective HEMS in mountain rescue.

    Opioids are the oldest and most potent drugs for the treatment of severe pain. Their clinical application is undisputed in acute (e.g., postoperative) and cancer pain, but their long-term use in chronic pain has met increasing scrutiny. This article reviews mechanisms underlying opioid analgesia and other opioid actions. It discusses the structure, function, and plasticity of opioid receptors; the central and peripheral sites of analgesic actions and side effects; endogenous and exogenous opioid receptor ligands; and conventional and novel opioid compounds. Challenging clinical situations, such as the tension between chronic pain and addiction, are also illustrated.

    Full Text Available Background: Emergency service workers are exposed to experienced traumatic events related to the nature of their work. The study aimed at identifying the role of cognitive processes, namely different forms of ruminations, as predictors of consequences of experienced trauma. Material and Methods: The data on 120 medical rescuers (80 men, 40 women who had experienced in their worksite at least 1 traumatic event in the last 5 years, were analyzed. The age of the participants ranged from 25 to 61 years (mean (M = 38.07; standard deviation (SD = 8.92. The following Polish versions of standardized tools were used: the Impact of Event Scale – Revised (IES-R, the Posttraumatic Growth Inventory (PTGI and the Event Related Rumination Inventory (ERRI. Results: The results of regression analyses indicated 2 significant predictors, intrusive rumination for posttraumatic stress disorder (PTSD and deliberate rumination for posttraumatic growth (PTG. Conclusions: Ruminations play an essential role in the occurrence of negative and positive outcomes of experienced trauma. The associations between PTSD and PTG, with different forms of ruminations, may be used in therapy, treating the appearance of intrusive rumination as an opportunity to turn towards active engagement in deliberate rumination, that facilitates the occurrence of posttraumatic growth.

  13. Laboratory testing for prescription opioids.

    Milone, Michael C

    2012-12-01

    Opioid analgesic misuse has risen significantly over the past two decades, and these drugs now represent the most commonly abused class of prescription medications. They are a major cause of poisoning deaths in the USA exceeding heroin and cocaine. Laboratory testing plays a role in the detection of opioid misuse and the evaluation of patients with opioid intoxication. Laboratories use both immunoassay and chromatographic methods (e.g., liquid chromatography with mass spectrometry detection), often in combination, to yield high detection sensitivity and drug specificity. Testing methods for opioids originated in the workplace-testing arena and focused on detection of illicit heroin use. Analysis for a wide range of opioids is now required in the context of the prescription opioid epidemic. Testing methods have also been primarily based upon urine screening; however, methods for analyzing alternative samples such as saliva, sweat, and hair are available. Application of testing to monitor prescription opioid drug therapy is an increasingly important use of drug testing, and this area of testing introduces new interpretative challenges. In particular, drug metabolism may transform one clinically available opioid into another. The sensitivity of testing methods also varies considerably across the spectrum of opioid drugs. An understanding of opioid metabolism and method sensitivity towards different opioid drugs is therefore essential to effective use of these tests. Improved testing algorithms and more research into the effective use of drug testing in the clinical setting, particularly in pain medicine and substance abuse, are needed.

    Adequate prehospital and inhospital primary care is a decisive factor in the successful treatment of multiple trauma patients. For optimization of treatment algorithms the implementation of a medical quality management is of utmost importance. The aim of this study was to extend quality management by including data on process quality. A retrospective study of primary rescue missions of the Helicopter Emergency Medical Service (HEMS) Christoph 22 in Ulm over a period of 2.5 years was performed. In a detailed analysis of filter criteria, in which relevant deviations from the recommendations (not fulfilled in  > 10% of the cases) occurred, process data was included (vital data, measurements and events). In the study population (n = 298, males 71.8%, mean age 39.8 ± 21.8 years) 2 filter criteria were identified in which relevant deviations where observed: time management where prehospital treatment time  ≤ 60 min in 36% of the cases was not fulfilled and circulatory management where the systolic blood pressure, detected with Riva-Rocci method (RR(sys))  ≥ 120 mmHg on hospital admission in patients with severe head trauma was not fulfilled in 45% of the cases. In patients with deviations in time management, prehospital treatment time was prolonged (75.6 ± 18.3 min versus 50.5 ± 6.7 min; p < 0.01) caused by a prolonged on scene attendance time (34.1 ± 22.1 min versus 20.6 ± 9.2 min; p < 0.01) and transport time (17.3 ± 9.4 min versus 13.3 ± 4.8 min; p < 0.01). In entrapment trauma prehospital treatment time was expanded (44% versus 10%; p < 0.01). Patients in whom circulatory management deviations were observed were more often in shock on arrival at the scene (RR(sys)  ≤ 90 mmHg: 60% versus 30%; p < 0.01), more often hypoxemic [pulse oximeter oxygen saturation (S(p)O(2)) ≤ 90%: 36% versus 19%; p < 0.05] and more often sustained a trauma to the chest as well as to chest and abdomen/pelvis (69% versus 52% and 42% versus 28%, respectively; p < 0

    The activities and range of maritime operations are all increasing following the nation' s maritime strategy, and at the same time, the incidence of dangerous situation and accidents at sea are increased too, so the forces of emergency medical rescue at sea which involves in the serious natural disasters and major accidents must be strengthened. Rapid response, high technology and good cooperation on medical rescue at sea are required according it' s characteristic. For the reason that medical treatment system at sea should be established to promote the crisis support capability, offshore medical rescue forces should be intensified to enhance the diverse support capability, platform of the medical treatment should be strengthened to fortify the remote support capability by the fundamental idea of "Mass Rescue", the entire capability of the emergency medical rescue forces at sea can be enhanced.%随着国家海洋战略的发展,海上行动越来越多,活动范围越来越大.海上发生险情和事故的频率也在增加,亟需提高海上重大自然灾害、重大事故等突发事件中的应急医学救援能力.海上医学救援具有任务的不确定性、医疗需求的多样性、组织的复杂性等特点,要求具备快速应对、全面技术、军地协调等能力.因此,应当以"大救援"理念为基石,把医学救援延伸到卫生应急体系,构建海上医疗救治体系以提高应急保障能力,强化海上医学救援力量的能力建设以提高多样化保障能力,加强海上医疗救治平台建设以提高远程保障能力,从而提升海上应急医学救援的总体能力.

  18. Laboratory Testing for Prescription Opioids

    OpenAIRE

    Milone, Michael C.

    2012-01-01

    Opioid analgesic misuse has risen significantly over the past two decades, and these drugs now represent the most commonly abused class of prescription medications. They are a major cause of poisoning deaths in the USA exceeding heroin and cocaine. Laboratory testing plays a role in the detection of opioid misuse and the evaluation of patients with opioid intoxication. Laboratories use both immunoassay and chromatographic methods (e.g., liquid chromatography with mass spectrometry detection),...

  19. Development of pharmaceutical heroin preparations for medical co-prescription to opioid dependent patients.

    Presently, there is a considerable interest in heroin-assisted treatment: co-prescription of heroin to certain subgroups of chronic, treatment-resistant, opioid dependent patients. In 2002, nine countries had planned (Australia, Belgium, Canada, France, Spain) or ongoing (Germany, The Netherlands, Switzerland, United Kingdom) clinical trials on this subject. These trials (and the routine heroin-assisted treatment programs that might result) will need pharmaceutical heroin (diacetylmorphine) to prescribe to the patients. Research into the development of pharmaceutical forms of heroin for prescription to addicts can benefit from the large amount of knowledge that already exists regarding this substance. Therefore, in this paper we review the physicochemical and pharmaceutical properties of diacetylmorphine and the clinically investigated routes of administration, as well as routes of administration utilised on the street in the context of developing pharmaceutical heroin formulations for prescription to addicts. Patient acceptability of the formulation is essential, because heroin-assisted treatment is aimed at treatment-resistant addicts, who often have to be encouraged to participate (or to maintain participation) in a treatment program. This means that the most suitable products would have pharmacokinetic profiles mimicking that of diacetylmorphine for injection, with rapid peak concentrations of diacetylmorphine and 6-acetylmorphine, ensuring the 'rush effect' and the sustained presence of morphine(-6-glucuronide) creating the prolonged euphoria. Diacetylmorphine for inhalation after volatilisation (via 'chasing the dragon') seems to be a suitable candidate, while intranasal and oral diacetylmorphine are currently thought to be unsuitable. However, oral and intranasal delivery systems might be improved and become suitable for use by heroin dependent patients.

    Full Text Available Abstract Background Due to tolerance development and adverse side effects, chronic pain patients frequently need to be switched to alternative opioid therapy Objective To assess the efficacy and tolerability of an alternative transdermally applied (TDS opioid in patients with chronic cancer pain receiving insufficient analgesia using their present treatment. Methods A total of 32 patients received alternative opioid therapy, 16 were switched from buprenorphine to fentanyl and 16 were switched from fentanyl to buprenorphine. The dosage used was 50% of that indicated in equipotency conversion tables. Pain relief was assessed at weekly intervals for the next 3 weeks Results Pain relief as assessed by VAS, PPI, and PRI significantly improved (p Conclusion Opioid switching at 50% of the calculated equianalgesic dose produced a significant reduction in pain levels and rescue medication. The incidence of side effects decreased and no new side effects were noted. Further studies are required to provide individualized treatment for patients according to their different types of cancer.

  1. American Society of Addiction Medicine (ASAM) National Practice Guideline for the Use of Medications in the Treatment of Addiction Involving Opioid Use

    2015-01-01

    The Centers for Disease Control have recently described opioid use and resultant deaths as an epidemic. At this point in time, treating this disease well with medication requires skill and time that are not generally available to primary care doctors in most practice models. Suboptimal treatment has likely contributed to expansion of the epidemic and concerns for unethical practices. At the same time, access to competent treatment is profoundly restricted because few physicians are willing and able to provide it. This “Practice Guideline” was developed to assist in the evaluation and treatment of opioid use disorder, and in the hope that, using this tool, more physicians will be able to provide effective treatment. Although there are existing guidelines for the treatment of opioid use disorder, none have included all of the medications used at present for its treatment. Moreover, few of the existing guidelines address the needs of special populations such as pregnant women, individuals with co-occurring psychiatric disorders, individuals with pain, adolescents, or individuals involved in the criminal justice system. This Practice Guideline was developed using the RAND Corporation (RAND)/University of California, Los Angeles (UCLA) Appropriateness Method (RAM) – a process that combines scientific evidence and clinical knowledge to determine the appropriateness of a set of clinical procedures. The RAM is a deliberate approach encompassing review of existing guidelines, literature reviews, appropriateness ratings, necessity reviews, and document development. For this project, American Society of Addiction Medicine selected an independent committee to oversee guideline development and to assist in writing. American Society of Addiction Medicine's Quality Improvement Council oversaw the selection process for the independent development committee. Recommendations included in the guideline encompass a broad range of topics, starting with the initial evaluation of

    Full Text Available Srinivas NalamachuInternational Clinical Research Institute and Pain Management Institute, Overland Park, KS, USAAbstract: Opioid rotation is a common and necessary clinical practice in the management of chronic non-cancer pain to improve therapeutic efficacy with the lowest opioid dose. When dose escalations fail to achieve adequate analgesia or are associated with intolerable side effects, a trial of a new opioid should be considered. Much of the scientific rationale of opioid rotation is based on the wide interindividual variability in sensitivity to opioid analgesics and the novel patient response observed when introducing an opioid-tolerant patient to a new opioid. This article discusses patient indicators for opioid rotation, the conversion process between opioid medications, and additional practical considerations for increasing the effectiveness of opioid therapy during a trial of a new opioid. A Patient vignette that demonstrates a step-wise approach to opioid rotation is also presented.Keywords: extended-release opioids, chronic pain, opioid rotation

    Currently opioids are the most frequently used medications for chronic noncancer pain. Opioid-induced constipation is the most common adverse effect associated with prolonged use of opioids, having a major impact on quality of life. There is an increasing need to treat opioid-induced constipation. With the recent approval of medications for the treatment of opioid-induced constipation, there are several therapeutic approaches. This review addresses the clinical presentation and diagnosis of opioid-induced constipation, barriers to its diagnosis, effects of opioids in the gastrointestinal tract, differential tolerance to opiates in different gastrointestinal organs, medications approved and in development for the treatment of opioid-induced constipation, and a proposed clinical management algorithm for treating opioid-induced constipation in patients with noncancer pain.

    Purpose Use of nonopioid analgesics (including nonsteroidal anti-inflammatory drugs) for postoperative pain management can reduce opioid consumption and potentially prevent opioid-related adverse events. This study examined the postoperative opioid-sparing effect of repeated-dose injectable diclofenac formulated with hydroxypropyl-β-cyclodextrin (HPβCD)-diclofenac. Patients and methods Pooled data from two double-blind, randomized, placebo- and active comparator-controlled Phase III trials were analyzed. Patients received HPβCD-diclofenac, placebo, or ketorolac by intravenous injection every 6 hours for up to 5 days following abdominal/pelvic or orthopedic surgery. Rescue opioid use was evaluated from the time of first study drug administration to up to 120 hours following the first dose in the overall study population and in subgroups defined by baseline pain severity, age, and HPβCD-diclofenac dose. Results Overall, 608 patients received ≥1 dose of study medication and were included in the analysis. While 93.2% of patients receiving placebo required opioids, the proportion of patients requiring opioids was significantly lower for patients receiving HPβCD-diclofenac (18.75, 37.5, or 50 mg) or ketorolac (P<0.005 for all comparisons). Mean cumulative opioid dose and number of doses were significantly lower among patients receiving HPβCD-diclofenac versus placebo for the 0–24 through 0–120 hour time periods (P<0.0001), as well as versus ketorolac for the 0–72 through 0–120 hour time periods (P<0.05). HPβCD-diclofenac significantly reduced opioid consumption versus placebo in subgroups based on baseline pain severity (moderate, severe) and age (<65 years, ≥65 years) from the 0–24 hour period onward. When compared to ketorolac, HPβCD-diclofenac also significantly reduced cumulative opioid consumption among patients with moderate baseline pain (0–72 through 0–120 hours) and opioid dose number among patients ≥65 years old (0–24 through 0

    2015-08-01

    To identify potential medication management issues associated with opioid use in older Australians. Retrospective cross-sectional review of the utilization of analgesics in 19,581 people who underwent a medication review in Australia between 2010 and 2012. Australian residents living in the community deemed at risk for adverse medication outcomes or any resident living fulltime in an aged care facility. Patient characteristics in those taking regularly dosed opioids and not and those taking opioid doses >120 mg and ≤120 mg MEQ/day were compared. Multivariable binary logistic regression was used to analyze the association between regular opioid and high dose opioid usage and key variables. Additionally, medication management issues associated with opioids were identified. Opioids were taken by 31.8% of patients, with 22.1% taking them regularly. Several major medication management issues were identified. There was suboptimal use of multimodal analgesia, particularly a low use of non-opioid analgesics, in patients taking regular opioids. There was extensive use (45%) of concurrent anxiolytics/hypnotics among those taking regular opioid analgesics. Laxative use in those prescribed opioids regularly was low (60%). Additionally, almost 12% of patients were taking doses of opioid that exceeded Australian recommendations. A significant evidence to practice gap exists regarding the use of opioids amongst older Australians. These findings highlight the need for a quick reference guide to support prescribers in making appropriate decisions regarding pain management in older patients with persistent pain. This should also be combined with patient and caregiver education about the importance of regular acetaminophen to manage persistent pain. Wiley Periodicals, Inc.

  15. Sprcial discussion: Future Roles for Tincture of Opium in Medical Intervention for Opioid Dependence Treads and Hopes

    Directory of Open Access Journals (Sweden)

    2009-02-01

    Full Text Available Opium tincture or tincture of opium (TOP, also known as Laudanum, is an alcoholic herbal preparation of opium. It is made by combining ethanol with opium latex or powder. After works of Paracelsus, the 16th century Swiss-German alchemist, who discovered that the alkaloids in opium are far more soluble in alcohol compared to water and named Opium tincture as Laudanum, this drug has been found a broad range of applications as the drug of choice for practically every ailment through 17th to 19th centuries. The early 20th century brought increased regulation of all manner of narcotics, including laudanum, as the addictive properties of opium became more widely understood. By the late 20th century, TOP's use was almost exclusively confined to treating severe diarrhea. During these thirty years, The efficacy and cost-effectiveness of opioid substitution therapy for the treatment of opioid addiction has been well documented by methadone and buprenorphine. Based on the idea of substitution therapy, TOP and slow releasing oral morphine (SROM have been proposed as the new alternatives. TOP could be used in three different ways in interventions for opioid dependency, first, as a supportive drug to reduce withdrawal syndrome during detoxification programs, second, as a substitution drug in long term maintenance, third, as a legal form of opioid drugs for harm reduction purposes. A little but growing evidences are supporting effectiveness of TOP for detoxification programs, in Iran, some preliminary open label studies showed effectiveness of TOP as a detoxifying drug in three to six month program, Now another open label study is evaluating TOP in a specific detoxification program with monthly evaluation and providing long term follow up after reaching to abstinence. There are a strong debate among the policy makers and clinicians on implementation of TOP in Iranian National Substance Abuse Treatment Facilities. In this article, We reviewed the proposed

  16. Chronic Opioid Therapy and Opioid Tolerance: A New Hypothesis

    Directory of Open Access Journals (Sweden)

    Joel S. Goldberg

    2013-01-01

    Full Text Available Opioids are efficacious and cost-effective analgesics, but tolerance limits their effectiveness. This paper does not present any new clinical or experimental data but demonstrates that there exist ascending sensory pathways that contain few opioid receptors. These pathways are located by brain PET scans and spinal cord autoradiography. These nonopioid ascending pathways include portions of the ventral spinal thalamic tract originating in Rexed layers VI–VIII, thalamocortical fibers that project to the primary somatosensory cortex (S1, and possibly a midline dorsal column visceral pathway. One hypothesis is that opioid tolerance and opioid-induced hyperalgesia may be caused by homeostatic upregulation during opioid exposure of nonopioid-dependent ascending pain pathways. Upregulation of sensory pathways is not a new concept and has been demonstrated in individuals impaired with deafness or blindness. A second hypothesis is that adjuvant nonopioid therapies may inhibit ascending nonopioid-dependent pathways and support the clinical observations that monotherapy with opioids usually fails. The uniqueness of opioid tolerance compared to tolerance associated with other central nervous system medications and lack of tolerance from excess hormone production is discussed. Experimental work that could prove or disprove the concepts as well as flaws in the concepts is discussed.

    Objective To summarize the special problems and corresponding countermeasures of highland medical rescue as a result of the challenges such as high cold and anoxia, bad weather, remote distance, traffic congestion and highly disperse casualties faced by the rescue activities in the Richter scale 7.1 earthquake that happened in Yushu on April 10, 2010, which was a violent earthquake that happened in the interior Tibetan region of Qinghai-Tibet Plateau with the world's highest altitude(4000 meters). Methods The features of injuries and the causes of death in Yushu earthquake were analyzed and compared to the classification of injuries, severity, causes of death and death time distribution in Wenchuan earthquake. The special traumatology problems of highland earthquake were analyzed. Results Yushu earthquake and plain earthquake were remarkably different in the traumatology and causes of death. Due to the soil, wood, sand and gravel structure of residential houses in Tibetan region, over 90%of houses collapsed in the earthquake, making crushing and burying injuries the main causes of death in Yushu earthquake, and emergency rescue measures had to be taken immediately. Due to the composite injuries caused by highland hypoxia, various kinds of trauma were liable to be complicated by acute respiratory distress syndrome and multiple organ dysfunction syndrome, and emergency aid and treatment had to be conducted. Therefore, aiming at the particularity of highland medical rescue in Yushu earthquake, a series of protective measures were proposed. Conclusion Based on the features of casualties, 48 hours after earthquake is the death peak period, thus the"Golden 48 hours"emergency rescue concept in highland earthquake is emphasized. Fast and organized transfer of the wounded people to low altitude and oxygen supply during transfer are the two keys of successful emergency rescue. Qingdao-Tibetan Plateau is an earthquake-prone area and therefore medical rescue has to be

    Opioids are increasingly used to manage not only acute but also chronic pain and heroine addiction. These patients usually receive many other medications that can interfere with the effects of opioids and vice versa. Patients often need combinations of drugs for their pain management, for treating opioid-related adverse effects or for other indications including depression and anxiety. Several antibiotics can also have interactions with opioids. It is important to understand what potential interactions exist between opioids and other drugs. Drug interactions can occur due to pharmacokinetic interactions including effects of absorption, metabolic pathways, drug transport through membranes and protein binding. Our knowledge of the metabolism of opioids has significantly increased over the last years and it is now possible to appreciate the role CYP enzymes, mainly CYP 2D6 and 3A4/5, in the metabolism of many commonly used opioids like codeine and oxycodone. Our knowledge regarding the role of the transporter proteins in drug interactions related to opioids is unfortunately meagre. Opioids inhibit the gastrointestinal system and can thus change the absorption of other drugs. Opioids can have synergistic or additive interactions with other drugs that have analgesic or sedative effects. Endogenous opioids control many physiological functions and exogenous opioids can have effects on all important transmitter systems (cholinergic, GABAergic, dopaminergic and serotonergic). The literature in this field is mainly based on case reports. Interindividual differences play an important role. Other potential interactions include prolongation of the QT-interval and lowering of the threshold for convulsions.

    A strong earthquake with a magnitude of 8.1 hit Nepal at 11:56 a.m. Nepal Standard Time on 25 April, killing 8019 people. Many international rescue teams hurried there, among which the China International Search and Rescue Team (CISAR) was the first to get to the disaster area in the very evening. It was the first rescue team that succeeded to rescue the first survivors from the ruins, and the first rescue team that conducted multinational joint search and rescue. With the greatest number of survivors rescued by team, CISAR combined the medical rescue and serach the most closely. And the following conclusions were summerized: ①medical rescue shpuld get seraching activity moving in the ruins, ②medical rounds with variety of forms should be carried out timely, and③targeted epidemic prevention and health education must be conducted.%2015年4月25日14:11,尼泊尔发生8.1级强烈地震。中国国际救援队参加了此次救援行动。是第一支到达灾区的国际重型救援队,是第一支营救出幸存者的救援队,是第一支真正实施多国联合搜救的救援队,是营救幸存者最多的救援队,是医疗救援与搜索营救结合最为紧密的救援队。笔者认为:①废墟现场的救援要把握医疗指导救援,医疗带动救援,高效合理科学施救的原则②适时开展形式多样、全方位、多角度的医疗巡诊③紧密结合当地气候和习俗特点,针对性的开展卫生防疫与宣教。这些经验对医疗队出国实施医疗救援具有重要的参考意义。

  2. Newer approaches to opioid detoxification

    2012-01-01

    Full Text Available Opioid use disorders present with distressing withdrawal symptoms at the time of detoxification. The pharmacological agents and methods currently in use for detoxification mainly include buprenorphine, methadone, and clonidine. Many other pharmacological agents have been tried for opioid detoxification. This review takes a look at the newer pharmacological options, both opioid agonists and non-agonist medications that have been utilized for detoxification. Peer reviewed articles were identified using PubMed and PsychInfo databases. The keywords included for the search were a combination of ′opioid′ and ′detoxification′ and their synonyms. All the articles published in the last 10 years were screened for. Relevant data was extracted from identified studies. Many newer pharmacological agents have been tried in detoxification of opioids. However, the quest for a safe, efficacious, cost-effective pharmacological option which requires minimal monitoring still continues. The role of non-pharmacological measures and alternative medicine needs further evaluation.

    This pilot study examined the context of nonmedical prescription opioid (NMPO) use and related risk behaviors among young adults in Rhode Island, a New England region with markedly high prevalence of NMPO use and overdose mortality. We conducted semi-structured interviews (n = 13) with young adults (18-29 year-olds) who reported current or recent NMPO use. We also conducted focus groups (two groups, n = 14 total) with professional service providers recruited from service organizations. Data were audio-recorded, transcribed, and key themes were analyzed. Participants discussed high levels of access to prescription opioids for nonmedical use via prescriptions originally provided to family and friends. The contexts described by participants included social environments such as parties, in which mixing opiates with benzodiazepines, alcohol or other types of drugs, and incidents of unintentional overdose were reported. Participants attributed risk for overdose to individual-level factors (eg, users who "couldn't handle it"), rather than contextual factors, and described negative reactions to being labeled as an "addict" or "addicted." Professional service providers had first-hand experience with young adults in treatment settings, yet limited exposure to young adults who were treatment-naïve. Young adult NMPO users described social settings where polysubstance use and pill use were common, and highlighted an aversion to being labeled as having a substance use disorder. To reduce harms of NMPO use among young adults, interventions should address the social context in which drug use and risk behaviors occur.

  12. Opioid Therapy for Chronic Nonmalignant Pain

    Directory of Open Access Journals (Sweden)

    Russell K Portenoy

    1996-01-01

    Full Text Available Long term administration of an opioid drug for chronic nonmalignant pain continues to be controversial, but is no longer uniformly rejected by pain specialists. This is true despite concerns that the regulatory agencies that oversee physician prescribing of opioid drugs continue to stigmatize the practice. The changing clinical perspective has been driven, in part, by widespread acknowledgement of the remarkably favourable outcomes achieved during opioid treatment of cancer pain. These outcomes contrast starkly with popular teaching about chronic opioid therapy and affirm the potential for prolonged efficacy, tolerable side effects, enhanced function associated with improved comfort and minimal risk of aberrant drug-related behaviours consistent with addiction. A large anecdotal experience in populations with nonmalignant pain suggests that these patients are more heterogeneous and that opioid therapy will greatly benefit some and will contribute to negative outcomes for others. The few controlled clinical trials that have been performed support the safety and efficacy of opioid therapy, but have been too limited to ensure generalization to the clinical setting. A critical review of the medical literature pertaining to chronic pain, opioid pharmacology and addiction medicine can clarify misconceptions about opioid therapy and provide a foundation for patient selection and drug administration. The available data support the view that opioids are no panacea for chronic pain, but should be considered in carefully selected patients using clinically derived guidelines that stress a structured approach and ongoing monitoring of efficacy, adverse effects, functional outcomes and the occurrence of aberrant drug-related behaviours.

  16. Opioid overuse pain syndrome (OOPS): the story of opioids, prometheus unbound.

    Mehendale, Anand W; Goldman, Mark P; Mehendale, Rachel P

    2013-01-01

    Throughout history, opioids have effectively alleviated pain but not without the risk of addiction and death. Seductive and dangerous, full of promise and destruction, opioids are both revered and feared by Western culture. Their exponential use in "developed countries" is now an enormous public health problem and requires us to harness their properties with scientific rigor and adequate safeguards. The use of opioids for the treatment of chronic nonterminal pain (CNTP) has been a relatively new phenomenon which has coincided with the proclamation by the Joint Commission on Accreditation of Health Care Organization in 2000 that pain assessment be the "fifth vital sign," notwithstanding the fact that pain is a symptom and not a sign.(1) Nonetheless, this resulted in a culture of a marked increase in use of opioids for acute and chronic pain management. Consequently, there are many unintended outcomes which include opioid-induced hyperalgesia increased diversion, addiction, and death. Understandably, this has resulted in many regulatory responses from such agencies such as the Drug Enforcement Administration (DEA) and state medical boards. This article proposes a clinically relevant paradigm of opioid overuse pain syndrome. The goal of this article is to inform the clinicians of the complicated neurobiology of opioids. It is our hope that scientists rather than government regulators dictate the appropriate response to the epidemic of over prescription of opioids. A similar designation of "medication overuse headache" has resulted in near extinction of excessive use of opioids in the field of headache medicine.

  19. Anger management style, opioid analgesic use, and chronic pain severity: a test of the opioid-deficit hypothesis.

    Science.gov (United States)

    Burns, John W; Bruehl, Stephen

    2005-12-01

    Anger management style is related to both acute and chronic pain. Recent research suggests that individuals who predominantly express anger (anger-out) may report heightened chronic pain severity due in part to endogenous opioid antinociceptive dysfunction. If exogenous opioids serve to remediate opioid deficits, we predicted that regular use of opioid analgesics by chronic pain patients would alter these relationships such that anger-out would be related to chronic pain severity only among opioid-free patients. For 136 chronic pain patients, anger management style, depression, anxiety, pain severity, and use of opioid and antidepressant medication was assessed. Results of hierarchical multiple regressions to predict chronic pain severity showed: (a) a significant Anger-out x Opioid use interaction such that high Anger-out was associated with high pain severity only among patients not taking opioids; (b) controlling for depressed affect and anxiety did not affect this association; (c) the Anger-out x Antidepressant use interaction was nonsignificant; (d) Anger-in did not interact with use of any medication to affect pain severity. Results are consistent with an opioid-deficit hypothesis and suggest that regular use of opioid medications by patients high in anger expression may compensate for an endogenous opioid deficit, and mitigate the effects of elevated anger expression on chronic pain intensity.

    2014-05-01

    Patients undergoing bariatric surgery are at high risk of postoperative nausea and vomiting (PONV). Despite triple PONV prophylaxis, up to 42.7% of patients require antiemetic rescue medication (AERM). This prospective, randomized study was conducted from November 2011 to October 2012. In the Classic group (n=59), patients underwent general anaesthesia with volatile anaesthetics and opioids. In the Total i.v. anaesthesia (TIVA) group (n=60), patients underwent opioid-free TIVA with propofol, ketamine, and dexmedetomidine. The severity of PONV was assessed using a Likert scale (none, mild, moderate, and severe). Patients in both groups had similar clinical characteristics, surgical procedure, and PONV risk scores and required similar amounts of postoperative opioid. In the Classic group, 22 patients (37.3%) reported PONV compared with 12 patients (20.0%) in the TIVA group [P=0.04; risk 1.27 (1.01-1.61)]. The absolute risk reduction was 17.3% (number-needed-to-treat=6). The severity of nausea was statistically different in both groups (P=0.02). The severity of PONV was significantly worse in the Classic group. There was no difference either in the number of patients requiring AERM in the postoperative period or in the number of AERM doses required. This prospective randomized study demonstrates that opioid-free TIVA is associated with a large reduction in relative risk of PONV compared with balanced anaesthesia. Clinical trial registration NCT 01449708 (ClinicalTrials.gov).

    Opioids have been used for centuries to treat a variety of psychiatric conditions with much success. The so-called "opium cure" lost popularity in the early 1950s with the development of non-addictive tricyclic antidepressants and monoamine oxidase inhibitors. Nonetheless, recent literature supports the potent role of methadone, buprenorphine, tramadol, morphine, and other opioids as effective, durable, and rapid therapeutic agents for anxiety and depression. This article reviews the medical literature on the treatment of psychiatric disorders with opioids (notably, methadone and buprenorphine) in both the non-opioid-dependent population and in the opioid-dependent methadone maintenance population. The most recent neurotransmitter theories on the origin of depression and anxiety will be reviewed, including current information on the role of serotonin, N-Methyl d-Aspartate, glutamate, cortisol, catecholamine, and dopamine in psychiatric disorders. The observation that methadone maintenance patients with co-existing psychiatric morbidity (so called dual diagnosis patients) require substantially higher methadone dosages by between 20% and 50% will be explored and qualified. The role of methadone and other opioids as beneficial psychiatric medications that are independent of their drug abuse mitigating properties will be discussed. The mechanisms by which methadone and other opioids can favorably modulate the neurotransmitter systems controlling mood will also be discussed.

  6. The Third Force-Medical rescue effort in protecting public safety in metropolitan communities%第三支力量——论城市社区保护公众生命健康的医学救援

    Institute of Scientific and Technical Information of China (English)

    李宗浩

    2013-01-01

    Guided by the concept of scientific development, historical background of domestic and international medical rescue service for both normal and emergency state was retrospectively reviewed, and the model of metropolitan emergency system and its operation in those developed countries was introduced in this paper. Furthermore, with understanding of the weakness in our medical rescue mission, the concept of "Third Force", a medical rescue system which serves as the safeguard to our public safety, is being introduced, as well as its implementation. We all appreciate peacefulness which police force makes great effort in public safety, and a reduced loss which firemen strived in a disaster. But on-site medical rescue is still a weak part in our present medical service. Back to the 80s , an integrity of which police, fireman, and medical rescue personnel teamed up in handling emergency incidents in normal state emerged in the Western countries, Japan, and Hong Kong (special administrative region) with feature of being efficient in taking emergency calls and dispatching. For instance, emergency medical service (EMS), an integral part in the 911 system in the United States, carries out more work load than either police or firemen in normal state. It has been entitled as one of the three forces that keep the society peaceful. Once a major disaster occurred, the three forces carried out a significant integral effort with sufficient resources from different aspects of the society. The integral effort has been proved in the 911 incident back to 2001 in the U.S., of which the paramedic and the emergency technician had received full praise from the authorities and the whole society. While the Western countries have been working towards to perfecting their EMS system, we were stillstruggling on walking out of hospital' s gate, resulting in no progress made in developing modern EMS. Therefore, considering our actual condition and the proven experience in the Western countries and

    Opioid misuse and abuse are growing concerns among the medical and public health communities. To examine the prevalence of indicators for potential opioid misuse in a large, commercially insured adult population. We adapted existing indicators developed by expert panels to include having overlapping opioid prescriptions, overlapping opioid and benzodiazepine prescriptions, long-acting/ extended release (LA/ER) opioids for acute pain,and high daily doses of opioids (>100 morphine milligram equivalents). These indicators were assessed among continuously enrolled individuals aged 18-64 years from the 2009 Truven Health MarketScan databases. Analyses were stratified by sex. We identified 3,391,599 eligible enrollees who received at least 1 opioid prescription. On average, enrollees obtained 3.3 opioid prescriptions, and the average annual days of supply was 47 days. Twice as many enrollees received opioid prescriptions for acute pain as for chronic pain. About a quarter of the enrollees had at least 1 indicator of either potential misuse by patients or inappropriate prescription practices by providers. About 15% of enrollees had high daily doses;7.8% had opioid overlap; and 7.9% had opioid and benzodiazepine overlap. Among those prescribed LA/ER opioids, 24.3% were treated for acute pain. Overlap indicators were more common among women. Our findings underscore the critical need to develop programs aimed at promoting appropriate use of opioids. Retrospective opioid utilization reviews similar to our analyses can potentially help managed care organizations and healthcare providers improve patient care and reduce the risk of adverse outcomes related to these medications.

    Chronic pain is a highly prevalent medical problem in the United States. Although opioids and serotonin-norepinephrine reuptake inhibitors (SNRIs) have demonstrated efficacy for relief of chronic pain, each has risks of adverse events in patients. Because of the risk of opioid abuse and addiction, combinations reducing opioid requirements are particularly valuable. Opioid and SNRI agents relieve pain by different pathways; concurrent use of each agent separately offers many potential benefits: complementary and possibly synergistic analgesic efficacy, separate titrations of opioid and SNRI effects, and the reduction of opioid requirements. However, few clinical studies have investigated the ideal ratios for combinations of opioids and SNRIs. A number of factors affect whether specific combinations have additive, synergistic, less than additive efficacy, or increase adverse events in patients, including general pharmacokinetic considerations, the potential for pharmacodynamic drug interactions, dose, and timing. Because there is little clinical evidence guiding combination therapy with separate opioid and SNRI agents, using single-molecule agents provides safe and effective therapy and should be the first option presented to patients. The use of empiric combinations of separate opioid and SNRI combinations needs to be considered in light of clinical cautions, including the lack of published evidence to guide dose conversion from any opioid to tramadol or to tapentadol, and vice versa; the need to avoid combinations with known drug interactions; and the need to titrate the dose when adding an SNRI to an opioid, and vice versa.

    The introduction of the Dmt (2',6'-dimethyl-L-tyrosine)-Tic pharmacophore into the design of opioid ligands produced an extraordinary family of potent delta-opioid receptor antagonists and heralded a new phase in opioid research. First reviewed extensively in 1998, the incorporation of Dmt into a diverse group of opioid molecules stimulated the opioid field leading to the development of unique analogues with remarkable properties. This overview will document the crucial role played by this residue in the proliferation of opioid peptides with high receptor affinity (K(i) equal to or less than 1 nM) and potent bioactivity. The discussion will include the metamorphosis between delta-opioid receptor antagonists to delta-agonists based solely on subtle structural changes at the C-terminal region of the Dmt-Tic pharmacophore as well as their behavior in vivo. Dmt may be considered promiscuous due to the acquisition of potent mu-agonism by dermorphin and endomorphin derivatives as well as by a unique class of opioidmimetics containing two Dmt residues separated by alkyl or pyrazinone linkers. Structural studies on the Dmt-Tic compounds were enhanced tremendously by x-ray diffraction data for three potent and biologically diverse Dmt-Tic opioidmimetics that led to the development of pharmacophores for both delta-opioid receptor agonists and antagonists. Molecular modeling studies of other unique Dmt opioid analogues illuminated structural differences between delta- and mu-receptor ligand interactions. The future of these compounds as therapeutic applications for various medical syndromes including the control of cancer-associated pain is only a matter of time and perseverance.

    Evidence suggests a link between opioid use and kidney disease. This review summarizes the known renal manifestations of opioid use including its role in acute and chronic kidney injury. Both the direct and indirect effects of the drug, and the context which leads to the development of renal failure, are explored. While commonly used safely for pain control and anesthesia in those with kidney disease, the concerns with respect to side effects and toxicity of opioids are addressed. This is especially relevant with the worldwide increase in the use of opioids for medical and recreational use. PMID:28117754

    2017-01-01

    Background Opioid use disorders are a growing public health problem in the United States. Most women who are opioid dependent are of childbearing age and management of opioid dependence during pregnancy poses unique challenges. Assessment includes evaluation for addiction, withdrawal syndromes, and co-morbid psychiatric diagnoses. Consultation-liaison psychiatrists may also be involved in acute pain management, perinatal medication management, buprenorphine induction and stabilization. For the past four decades, the standard of care has included methadone maintenance, but the increasing use of buprenorphine creates new treatment issues and opportunities. Objective To educate consultation-liaison psychiatrists in emergency and obstetrical settings about the appropriate approach toward the evaluation and basic management of women with opioid dependence in pregnancy. Method The authors reviewed the consensus literature and all new treatment options on opioid dependence during pregnancy. Discussion In this review, the authors summarize known and emerging management strategies for opioid dependence in pregnancy pertinent to consultation-liaison psychiatrists. PMID:22902085

    Using latent class analysis, this study examined the pattern of non-opioid substance misuse among 19,101 enrollees into 85 opioid treatment programs. The most frequent non-opioid drugs were cannabis, anti-anxiety medications, and cocaine. Four non-opioid drug use latent classes were identified: low-use (73%), prescription drug use (16%), marijuana and cocaine use (8.5%), and poly-drug use (2.5%). Compared to the low-use class, participants in the other classes were more likely to be female, Caucasian, use tobacco, have chronic pain, and use prescription opioids either with or without heroin. Recognition of characteristics derived from these classes can improve opioid treatment program services.

    Although tramadol has been used in the management of acute withdrawal in patients with opioid dependence, its use for maintenance treatment as a harm reduction approach has not been assessed systematically. This case series describes patients with opioid dependence who were treated with tramadol for long-term maintenance. Patients with opioid dependence who received treatment at the National Drug Dependence Treatment Centre of All India Institute of Medical Sciences, New Delhi, were included in the study. Patients who received at least 6 months of tramadol and had follow-up adherence of more than 80% were included in the case series. A total of 25 cases were included, all of whom were males. The types of opioids being taken at the time of initiation of tramadol were natural opiates (poppy husk and raw opium), followed by heroin. The median dose of tramadol at initiation and maintenance was 300 mg/day. Nineteen patients were able to achieve complete abstinence to other opiates on tramadol. Tramadol may be an effective option in the long-term management of patients with opioid dependence. Further studies are required for establishing the efficacy of tramadol for agonist management of patients with opioid dependence.

  1. The Opioid Epidemic: Crisis and Solutions.

    Science.gov (United States)

    Skolnick, Phil

    2017-10-02

    The widespread abuse of prescription opioids and a dramatic increase in the availability of illicit opioids have created what is commonly referred to as the opioid epidemic. The magnitude of this epidemic is startling: About 4% of the adult US population misuses prescription opioids, and in 2015, more than 33,000 deaths were attributable to overdose with licit and illicit opioids. Increasing the availability of medication-assisted treatments (such as buprenorphine and naltrexone), the use of abuse-deterrent formulations, and the adoption of US Centers for Disease Control and Prevention prescribing guidelines all constitute short-term approaches to quell this epidemic. However, with more than 125 million Americans suffering from either acute or chronic pain, the development of effective alternatives to opioids, enabled at least in part by a fuller understanding of the neurobiological bases of pain, offers the best long-term solution for controlling and ultimately eradicating this epidemic. Expected final online publication date for the Annual Review of Pharmacology and Toxicology Volume 58 is January 6, 2018.

  6. PSYCHOLOGICAL ASSESSMENT OF OPIOID DRUG ABUSE

    Directory of Open Access Journals (Sweden)

    José Luis Carballo

    2016-01-01

    Full Text Available The increase in the prescription of opioid analgesics is related to increased rates of opioid abuse and the negative consequences of medication misuse. Several international health organisations recommend comprehensive and multidisciplinary patient assessment for the duration of the opioid treatment in order to identify and prevent medication abuse. Due to the lack of specific clinical guidelines in the Spanish National Health System, the aim of this paper is to present a proposal for psychological assessment based on the main psychological tools currently available for assessing opioid abuse. The assessment guidelines have been established based on the psychological variables that can predict and prolong the abuse, classifying all of the variables depending on the current stage of the therapeutic process for each patient. Although there are instruments with good psychometric properties, further research is necessary to adapt, translate and validate these instruments for use in the Spanish population. Future studies are also needed to investigate intervention and prevention strategies in depth in order to reduce the likelihood of abuse in patients treated with opioids.

    Restless legs syndrome (RLS) is a distressing and common neurological disorder that may have a huge impact in the quality of life of those with frequent and intense symptoms. Patients complain of unpleasant sensations in the legs, at or before bedtime, and feel an urge to move the legs, which improves with movement, such as walking. Symptoms start with the patient at rest (e.g. sitting or lying down), and follow a circadian pattern, increasing during the evening or at night. Many pharmacological intervention are available for RLS, including drugs used to treat Parkinson's disease (L-Dopa and dopaminergic agonists), epilepsy (anticonvulsants), anxiety (benzodiazepines), and pain (opioids). Dopaminergic drugs are those most frequently used for treatment of RLS, but some patients do not respond effectively and require other medication. Opioids, a class of medications used to treat severe pain, seem to be effective in treating RLS symptoms, and are recommended for patients with severe symptoms, because RLS and pain appear to share the same mechanism in the central nervous system. All available drugs are associated to some degree with side effects, which can impede treatment. Opioids are associated with adverse events such as constipation, tolerance, and dependence. This justifies the conduct of a systematic review to ascertain whether opioids are safe and effective for treatment of RLS. To asses the effects of opioids compared to placebo treatment for restless legs syndrome in adults. We searched the Cochrane Central Register of Controlled trials, CENTRAL 2016, issue 4 and MEDLINE, EMBASE, and LILACS up to April 2016, using a search strategy adapted by Cochraneto identify randomised clinical trials. We checked the references of each study and established personal communication with other authors to identify any additional studies. We considered publications in all languages.

    Prescription opioid analgesic use has quintupled recently. Evidence linking opioid use with depression emanates from animal models and studies of persons with co-occurring substance use and major depression. Little is known about depressogenic effects of opioid use in other populations. The purpose of this study was to determine whether prescription opioids are associated with increased risk of diagnosed depression. Retrospective cohort study, new user design. Medical record data from 49,770 US Department of Veterans Affairs (VA) health care system patients with no recent (24-month) history of opioid use or a diagnosis of depression in 1999 and 2000. Propensity scores were used to control for bias by indication, and the data were weighted to balance the distribution of covariates by duration of incident opioid exposure. Cox proportional hazard models with adjustment for painful conditions were used to estimate the association between duration of prescription opioid use and the subsequent risk of development of depression between 2001 and 2007. Of 49,770 patients who were prescribed an opioid analgesic, 91 % had a prescription for 180 days. Compared to patients whose prescription was for opioid prescription increased (HR = 1.25; 95 % CI: 1.05-1.46 for 90-180 days, and HR = 1.51; 95 % CI:1.31-1.74 for > 180 days). In this sample of veterans with no recent (24-month) history of depression or opioid analgesic use, the risk of development of depression increased as the duration of opioid analgesic exposure increased. The potential for depressogenic effect should be considered in risk-benefit discussions, and patients initiating opioid treatment should be monitored for development of depression.

    Long-term opioid use for noncancer pain is increasingly prevalent yet controversial given the risks of addiction, diversion, and overdose. Prior literature has identified the problem and proposed management guidelines, but limited evidence exists on the actual effectiveness of implementing such guidelines in a primary care setting.A multidisciplinary working group of institutional experts assembled comprehensive guidelines for chronic opioid prescribing, including monitoring and referral recommendations. The guidelines were disseminated in September 2013 to our medical center's primary care clinics via in person and electronic education.We extracted electronic medical records for patients with noncancer pain receiving opioid prescriptions (Rxs) in seasonally matched preintervention (11/1/2012-6/1/2013) and postintervention (11/1/2013-6/1/2014) periods. For patients receiving chronic (3 or more) opioid Rxs, we assessed the rates of drug screening, specialty referrals, clinic visits, emergency room visits, and quantity of opioids prescribed.After disseminating guidelines, the percentage of noncancer clinic patients receiving any opioid Rxs dropped from 3.9% to 3.4% (P = 0.02). The percentage of noncancer patients receiving chronic opioid Rxs decreased from 2.0% to 1.6% (P = 0.03). The rate of urine drug screening increased from 9.2% to 17.3% (P = 0.005) amongst noncancer chronic opioid patients. No significant differences were detected for other metrics or demographics assessed.An educational intervention for primary care opioid prescribing is feasible and was temporally associated with a modest reduction in overall opioid Rx rates. Provider use of routine drug screening increased, but overall rates of screening and specialty referral remained low despite the intervention. Despite national pressures to introduce opioid prescribing guidelines for chronic pain, doing so alone does not necessarily yield substantial changes in clinical practice.

    Full Text Available In 145 patients with opioid addiction were studied prognostic factors of the formation of the disease and their medical and social consequences. In the examined patients duration of the narcotization was from 1 year to 15 years. Analysis of studies showed that the most significant adverse prognostic factors, determining formation rate of medical and social consequences in opioid addiction, may include: perinatal pathology, personality deviation in the premorbid; early age of onset of drug use; hereditary load addictive and mental illness; condition of upbringing; alcohol abuse prior to narcotization; prescription of narcotization. These constitutionally-biological factors are informative indicators in the predicting the formation of opioid dependence.

    Clinical studies comparing the response and side effects of various opioids have not been able to show robust differences between drugs. Hence, recommendations of the regulatory authorities have been driven by costs with a general tendency in many countries to restrict physician's use of opioids...... to morphine. Although this approach is recognized as cost-effective in most cases there is solid evidence that, on an individual patient basis, opioids are not all equal. Therefore it is important to have an armamentarium of strong analgesics in clinical practice to ensure a personalized approach in patients...... who do not respond to standard treatment. In this review we highlight differences between opioids in human studies from a pharmacological, experimental, clinical and health economics point of view. We provide evidence that individuals respond differently to opioids, and that general differences...

    Despite the increasing number of prescriptions written to adolescents and young adults for opioid analgesics, the rise in non-medical use of such drugs among university students, and the potential role of craving in the misuse of opioids, there have been no published studies assessing craving for prescription opioids in this population. Therefore, the current study was designed to assess the impact of prescription opioid-related cue exposure on craving in university students. Students (n=277) recruited from a large university in the Midwestern United States were randomly assigned to two conditions to test the impact of cue exposure to either prescription opioid-related stimuli or control stimuli. Relative to the control condition, prescription opioid-related cue exposure significantly increased overall craving, desire and intention to use prescription opioids, relief from negative states by using prescription opioids, and perceived control over prescription opioid use. In addition, when assessing correlates of post-cue exposure craving, negative mood and procurement of prescription opioids from non-medical sources were the only measured variables that were significantly associated with overall craving and/or any of the craving measure's subscales. Craving may be important aspect of prescription opioid use among university students. Future research assessing craving as a function of non-medical user subtype is warranted.

  16. Experience of the use of Ketamine to manage opioid withdrawal in an addicted woman: a case report.

    Opioids are good painkillers, but many patients treated with opioids as painkillers developed a secondary addiction. These patients need to stop misusing opioids, but the mild-to-severe clinical symptoms associated with opioid withdrawal risk increasing their existing pain. In such cases, ketamine, which is used by anaesthetists and pain physicians to reduce opioid medication, may be an effective agent for managing opioid withdrawal. We describe the case of a woman who developed a severe secondary addiction to opioids in the context of lombo-sciatic pain. She presented a severe opioid addiction, and her physicians refused to prescribe such high doses of opioid treatment (oxycontin® extended-release 120 mg daily, oxycodone 60 mg daily, and acetaminophen/codeine 300 mg/25 mg 6 times per day). To assist her with her opioid withdrawal which risked increasing her existing pain, she received 1 mg/kg ketamine oral solution, and two days after ketamine initiation her opioid treatment was gradually reduced. The patient dramatically reduced the dosage of opioid painkillers and ketamine was withdrawn without any withdrawal symptoms. Ketamine displays many interesting qualities for dealing with all symptoms relating to opioid withdrawal. Accordingly, it could be used instead of many psychotropic treatments, which interact with each other, to help with opioid withdrawal. However, the literature describes addiction to ketamine. All in all, although potentially addictive, ketamine could be a good candidate for the pharmacological management of opioid withdrawal.

    2005-01-01

    In Part I of this series, I discussed the basic role of the law in the decision-making process for opioid management. I set out three basic rules: 1) read and learn applicable federal and state legal/regulatory materials on using controlled substances to treat pain, 2) stay current on accepted clinical standards of care, and 3) use a compliance program to minimize the potential for abuse and diversion of controlled substances. Here in Part II, I focus on the third rule and offer a few suggestions on developing and maintaining a compliance program. I also discuss using language from legal/regulatory materials in your practice forms in a manner that, once again, allows you to "take back your turf" and prescribe opioids without fear of legal/regulatory sanction (see Disclaimer). Take a minute to review the self-audit questions that follow and see where you stand on your knowledge and use of legal/regulatory matters in your daily practice. More "yes" answers indicate better knowledge of key compliance and documentation issues. More "no" and "I don't know" answers indicate that more work should be done to minimize potential legal/regulatory compliance problems in your practice.

    To celebrate the 80th anniversary of creation of organized mine rescue activities in Poland, a symposium organized by the Central Mine Rescue Station in Bytom and the Association of Mining Engineers and Technicians in Katowice took place on 28-30 September 1987 in Szczyrk and was attended by 53 representatives of mine rescue services from 15 countries. Nineteen papers by Polish participants and 21 papers by foreign participants were presented on three main topics: modern methods of fighting mining hazards; lines of improvement for mine rescue services; modern mine rescue equipment. Polish-made equipment for mine rescue, hazard detection and combating hazards was exhibited. The Central Mine Rescue Station in Bytom presented a tender for such services as technical consulting, expertise, development of technology and direct participation in rescue operations. Participants to the symposium addressed the Organizing Committee of the World Mining Congress to include mine rescue issues in the program of the next Congress.

    Opioids are the primary drugs used in Western medicine for pain management and palliative care. Farming of opium poppies remains the sole source of these essential medicines, despite diverse market demands and uncertainty in crop yields due to weather, climate change, and pests. We engineered yeast to produce the selected opioid compounds thebaine and hydrocodone starting from sugar. All work was conducted in a laboratory that is permitted and secured for work with controlled substances. We combined enzyme discovery, enzyme engineering, and pathway and strain optimization to realize full opiate biosynthesis in yeast. The resulting opioid biosynthesis strains required the expression of 21 (thebaine) and 23 (hydrocodone) enzyme activities from plants, mammals, bacteria, and yeast itself. This is a proof of principle, and major hurdles remain before optimization and scale-up could be achieved. Open discussions of options for governing this technology are also needed in order to responsibly realize alternative supplies for these medically relevant compounds.

    Over the past decade, there has been a substantial rise in the use of opioids for the treatment of chronic noncancer pain. Despite the potential benefits of opioid therapy, the rise in the use of opioids has been accompanied by escalating rates of prescription opioid misuse and addiction. There is now a growing body of evidence indicating that opioid craving (i.e., the subjective desire to consume opioids) is one of the strongest determinants of opioid misuse among patients with chronic pain prescribed opioids. Although research has elucidated some of the factors associated with opioid craving, the contribution of patients' levels of pain to opioid craving remains unclear. The main objective of this study was to examine the day-to-day association between pain and opioid craving. In this longitudinal cohort study, patients with chronic pain prescribed opioid therapy completed baseline measures and were then asked to provide daily reports of pain intensity and opioid craving for a period of 14 days. Multilevel analyses indicated that day-to-day elevations in patients' levels of pain were associated with heightened opioid craving. That is, on more painful days, patients reported higher levels of craving. Within-person changes in pain intensity, however, explained less than 5% of the variance in patients' reports of craving. Findings from this study suggest that patients with chronic pain do not crave their opioid medications simply because they experience high levels of pain. The theoretical and clinical implications of our findings are discussed. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

  2. Who Benefits from Chronic Opioid Therapy? Rethinking the Question of Opioid Misuse Risk

    Directory of Open Access Journals (Sweden)

    2016-05-01

    Full Text Available Beginning in the late 1990s, a movement began within the pain management field focused upon the underutilization of opioids, thought to be a potentially safe and effective class of pain medication. Concern for addiction and misuse were present at the start of this shift within pain medicine, and an emphasis was placed on developing reliable and valid methods and measures of identifying those at risk for opioid misuse. Since that time, the evidence for the safety and effectiveness of chronic opioid therapy (COT has not been established. Rather, the harmful, dose-dependent deleterious effects have become clearer, including addiction, increased risk of injuries, respiratory depression, opioid induced hyperalgesia, and death. Still, many individuals on low doses of opioids for long periods of time appear to have good pain control and retain social and occupational functioning. Therefore, we propose that the question, “Who is at risk of opioid misuse?” should evolve to, “Who may benefit from COT?” in light of the current evidence.

    We aimed to examine pharmacologic, demographic and medical comorbidity risk factors for opioid-related mortality among patients currently receiving methadone for an opioid use disorder. We conducted a population-based, nested case-control study linking healthcare and coroner's records in Ontario, Canada, from January 31, 1994 to December 31, 2010. We included social assistance recipients receiving methadone for an opioid use disorder. Within this group, cases were those who died of opioid-related causes. For each case, we identified up to 5 controls matched on calendar quarter. The primary analysis examined the association between use of psychotropic drugs (benzodiazepines, antidepressants or antipsychotics) and opioid-related mortality. Secondary analyses examined the associations between baseline characteristics, health service utilization, comorbidities and opioid-related mortality. Among 43,545 patients receiving methadone for an opioid use disorder, we identified 175 (0.4%) opioid-related deaths, along with 873 matched controls. Psychotropic drug use was associated with a two fold increased risk of opioid-related death (adjusted odds ratio (OR) 2.0; 95% confidence interval (CI) 1.2 to 3.5). Specifically, benzodiazepines (adjusted OR 1.6; 95% CI 1.1 to 2.5) and antipsychotics (adjusted OR 2.3; 95% CI 1.5 to 3.5) were independently associated with opioid-related death. Other associated factors included chronic lung disease (adjusted OR 1.7; 95% CI 1.2 to 2.6), an alcohol use disorder (adjusted OR 1.9; 95% CI 1.2 to 3.2), mood disorders (adjusted OR 1.8; 95% CI 1.0 to 3.2), and a history of heart disease (adjusted OR 5.3; 95% CI 2.0 to 14.0). Psychotropic drug use is associated with opioid-related death in patients receiving methadone. Mindfulness of these factors may reduce the risk of death among methadone recipients.

In particular, proposed extensions of buprenorphine treatment, a critically effective intervention for opioid use disorder (OUD, are cautiously considered due to the potential risk of misuse or abuse.2 General practitioners are already facing this burden daily in the treatment of chronic pain, and expert supervision and treatment model adjustment are needed to help improve outcomes. Approximately 20% of patients in primary care have noncancer pain symptoms, with most of them receiving opioid prescriptions by their physicians, and their number is increasing.3 Pain diagnoses are comparable in severity to those of tertiary centers and are complicated by significant psychiatric comorbidity, with a measurable lifetime risk of developing OUD.4,5 Some primary care physicians report frustration about opioid abuse and diversion by their patients; support from pain specialists would improve their competence, the quality f their performance, and the ability to identify patients at risk of opioid misuse.6 Thus, buprenorphine treatment should not be adding to a complex clinical scenario. To this end, the promising models of care emphasize the integration of medical with psychological and pharmacological expertise for the management of OUD. 

  6. New opioid prescribing guidelines favor non-opioid alternatives.

    Science.gov (United States)

    2016-05-01

    Determined to make a dent in the growing problem of opioid addiction, the CDC has unveiled new guidelines for opioid prescribing for chronic pain. The recommendations urge providers to be more judicious in their prescribing, opting for opioids only after carefully weighing substantial risks and benefits. Public health authorities note the rampant use and misuse of opioids have "blurred the lines" between prescription opioids and illicit opioids. The new guidelines are designed to help frontline providers balance the need to manage their patients' chronic pain with the duty to curb dangerous prescribing practices. The recommendations are built around three principles: favor non-opioid alternatives for most cases of chronic pain, use the lowest effective dose when prescribing opioids, and exercise caution/monitor patients who are treated with opioids.

    Opioid-induced constipation (OIC), a prevalent and distressing side effect of opioid therapy, does not reliably respond to treatment with conventional laxatives. OIC can be a treatment-limiting adverse event. Recent advances in medications with peripherally acting μ-opioid receptor antagonists, such as methylnaltrexone, naloxegol, and alvimopan, hold promise for treating OIC and thus extending the benefits of opioid analgesia to more chronic pain patients. Peripherally acting μ-opioid receptor antagonists have been clinically tested to improve bowel symptoms without compromise to pain relief, although there are associated side effects, including abdominal pain. Other treatment options include fixed-dose combination products of oxycodone analgesic together with naloxone. PMID:28176913

    Krantz, Mori J; Mehler, Philip S

    2004-02-01

    Almost 3 million Americans have abused heroin. The most effective treatment for this concerning epidemic is opioid replacement therapy. Although, from a historical perspective, acceptance of this therapy has been slow, growing evidence supports its efficacy. There are 3 approved medications for opioid maintenance therapy: methadone hydrochloride, levomethadyl acetate, and buprenorphine hydrochloride. Each has unique characteristics that determine its suitability for an individual patient. Cardiac arrhythmias have been reported with methadone and levomethadyl, but not with buprenorphine. Due to concerns about cardiac risk, levomethadyl use has declined and the product may ultimately be discontinued. These recent safety concerns, specifics about opioid detoxification and maintenance, and new federal initiatives were studied. Opioid detoxification has a role in both preventing acute withdrawal and maintaining long-term abstinence. Although only a minority of eligible patients are engaged in treatment, opioid maintenance therapy appears to offer the greatest public health benefits. There is growing interest in expanding treatment into primary care, allowing opioid addiction to be managed like other chronic illnesses. This model has gained wide acceptance in Europe and is now being implemented in the United States. The recent Drug Addiction Treatment Act enables qualified physicians to treat opioid-dependent patients with buprenorphine in an office-based setting. Mainstreaming opioid addiction treatment has many advantages; its success will depend on resolution of ethical and delivery system issues as well as improved and expanded training of physicians in addiction medicine.

    Full Text Available Abstract Background Opioid misuse can complicate chronic pain management, and the non-medical use of opioids is a growing public health problem. The incidence and risk factors for opioid misuse in patients with chronic pain, however, have not been well characterized. We conducted a prospective cohort study to determine the one-year incidence and predictors of opioid misuse among patients enrolled in a chronic pain disease management program within an academic internal medicine practice. Methods One-hundred and ninety-six opioid-treated patients with chronic, non-cancer pain of at least three months duration were monitored for opioid misuse at pre-defined intervals. Opioid misuse was defined as: 1. Negative urine toxicological screen (UTS for prescribed opioids; 2. UTS positive for opioids or controlled substances not prescribed by our practice; 3. Evidence of procurement of opioids from multiple providers; 4. Diversion of opioids; 5. Prescription forgery; or 6. Stimulants (cocaine or amphetamines on UTS. Results The mean patient age was 52 years, 55% were male, and 75% were white. Sixty-two of 196 (32% patients committed opioid misuse. Detection of cocaine or amphetamines on UTS was the most common form of misuse (40.3% of misusers. In bivariate analysis, misusers were more likely than non-misusers to be younger (48 years vs 54 years, p Conclusion Opioid misuse occurred frequently in chronic pain patients in a pain management program within an academic primary care practice. Patients with a history of alcohol or cocaine abuse and alcohol or drug related convictions should be carefully evaluated and followed for signs of misuse if opioids are prescribed. Structured monitoring for opioid misuse can potentially ensure the appropriate use of opioids in chronic pain management and mitigate adverse public health effects of diversion.

     Concurrent use of sedatives, especially anxiolytics, and opioids is associated with increased risk of medication-related harms. To the extent that multiple prescribers are involved, approaches to influence patterns of coprescribing will differ from those to influence prescribing within a single drug class.  Describe the proportion of new opioid recipients with concurrent sedative medications at opioid initiation and determine whether these medications were prescribed by the same prescriber.  We used national Department of Veterans Affairs (VA) outpatient pharmacy administration data to identify veterans who received a new opioid prescription between October 20, 2010, and September 1, 2011 (FY 2011), preceded by a 365-day opioid-free period. Concurrent sedative use was defined as a skeletal muscle relaxant, benzodiazepine, atypical antipsychotic, or hypnotic filled on the opioid start date or before and after the opioid start date with a gap of less than twice the day supply of the prior fill.  Concurrent sedative use at opioid initiation was 21.4% (112,408/526,499) in FY 2011. The proportion of concurrent recipients who received at least one concurrent sedative prescribed by a provider other than the opioid prescriber was 61.4% (69,002/112,408). The proportion of recipients who received a sedative concurrent with opioid initiation from the same prescriber varied across sedative class. Benzodiazepines and opioids were prescribed by the same provider in 41.1% (15,520/37,750) of concurrent users.  One in five patients newly prescribed opioids also had a sedative prescription. Less than half of patients with concurrent opioid and benzodiazepine prescriptions received these from the same provider. Efforts to reduce concurrent opioid and sedative prescribing will require addressing care coordination.

    Remifentanil appears to have pharmacodynamic properties similar to other potent mu opioid agonists. It does, however, have unique pharmacokinetic properties, with a rapid onset and rapid offset of effect, irrespective of the duration of its administration. With this property, remifentanil appears to be a very titratable opioid that will make it suitable for administration for either very brief periods, in which analgesia is required, or over prolonged periods, without the concern for prolonged recovery.

    Objective Prescription opioid abuse and addiction are serious problems with growing societal and medical costs, resulting in billions of dollars of excess costs to private and governmental health insurers annually. Though difficult to accurately assess, prescription opioid abuse also leads to increased insurance costs in the form of property and liability claims, and costs to state and local governments for judicial, emergency, and social services. This manuscript’s objective is to provide payers with strategies to control these costs, while supporting safe use of prescription opioid medications for patients with chronic pain. Method A Tufts Health Care Institute Program on Opioid Risk Management meeting was convened in June 2010 with private and public payer representatives, public health and law enforcement officials, pain specialists, and other stakeholders to present research, and develop recommendations on solutions that payers might implement to combat this problem. Results While protecting access to prescription opioids for patients with pain, private and public payers can implement strategies to mitigate financial risks associated with opioid abuse, using internal strategies, such as formulary controls, claims data surveillance, and claims matching; and external policies and procedures that support and educate physicians on reducing opioid risks among patients with chronic pain. Conclusion Reimbursement policies, incentives, and health technology systems that encourage physicians to use universal precautions, to consult prescription monitoring program (PMP) data, and to implement Screening, Brief Intervention, and Referral to6Treatment protocols, have a high potential to reduce insurer risks while addressing a serious public health problem.

This review attempts to outline the latest findings related to the therapeutic usefulness of a μ opioid receptor antagonist, methylnaltrexone in the treatment of opioid-induced constipation. The review highlights methylnaltrexone bromide (RelistorTM; Progenics/Wyeth a quaternary derivative of naltrexone, which was recently approved in the United States, Europe and Canada. The Food and Drug Administration in the United States approved a subcutaneous injection for the treatment of opioid bowel dysfunction in patients with advanced illness who are receiving palliative care and when laxative therapy has been insufficient. Methylnaltrexone is a peripherally restricted, μ opioid receptor antagonist that accelerates oral–cecal transit in patients with opioidinduced constipation without reversing the analgesic effects of morphine or inducing symptoms of opioid withdrawal. An analysis of the mechanism of action and the potential benefits of using methylnaltrexone is based on data from published basic research and recent clinical studies.Keywords: methylnaltrexone, constipation, opioid

    Objective To compare the community disaster medical emergency management systems adopted in America , Japan, Australia and China so as to provide reference for the improvement of such a system in China. Methods The mechanisms, management, preventive measures and performance of each country's community medical emergency system were summarized and compared. Results Community emergency management, preventive measures and education were strongly emphasized in America, Japan and Australia. The organizational structure of the community medical emergency system in China was full of departmental and regional barriers and has become a mere formality. Its performance was not satisfactory due to immature management and operational mechanism as well as poor preventive measures. Conclusion It is urgent for China to strengthen its community disaster medical emergency system. China should draw experience from the three above countries and take into account our own situation to build a reasonable community medical emergency management system.%目的 探讨美国、日本、澳大利亚和中国社区灾害医学应急管理的政策和措施,为提高我国社区灾害医学应急能力提供参考.方法 归纳、总结和比较各国社区灾害医学应急机制、管理、防范措施和绩效.结果 美、日、澳三国注重基层社区灾害应急管理,预防和前期教育为主,有较完善的保障体系;我国社区医学应急管理结构条块分割,防灾工作流于形式,运行机制与管理不成熟,防范措施不够全面,绩效不理想.结论 我国社区灾害医学应急管理体系建设亟待加强.应借鉴三国的经验,同时结合我国国情,建立合理的社区灾害医学救援应急体系.

    Over the past century, there were more than 40 earthquakes greater than 7 magnitude occurred worldwide, 10 of which in China, which killed 600 thousand people accounting for 53% of global earthquake deaths. On May 12, 2008, an 8.0-magnitude earthquake occurred in Wenchuan, Sichuan Province, causing 69000 deaths, 18000 missings, and 370000 injuries. Among 10 thousand severe injuries, most were traumatic injuries, 74% of which were fracture. On April 14, 2010, a 7.1-magnitude earthquake occurred in Yushu, Qinghai Province. There were 2698 deaths, 270 missings and 11000 injuries. Among 3100 severe injuries, fracture injuries accounted for 58.4%. After each earthquake, the Chinese Army Medical Services took actions and made quick response according to the law. They sent out elites with efficient command and scientific organization, fully participating in the medical rescue operations. After Wenchuan earthquake, 397 mobile medical service units and 7061 health workers were sent out. A total of 69,000 people were treated, and 22,000 cases of surgeries were performed. After Yushu earthquake, a total of 25 mobile medical service units and 2025 health workers were sent. They performed 1635 cases of surgeries with a miracle of "zero death" in mass earthquake casualties and altitude diseases in cold highlands. After each earthquake, injuries cured within 1 week accounted for 60% of the total, and patients evacuated accounted for 80% of the total, which owed to the effective first aid in site of Chinese army medical service. They effectively played the role as the main force, making significant contributions for the final victory of earthquake relief. From the practice of medical rescue revelation after the two earthquakes, what Chinese Army Medical Services learned are: firstly, the theory of medical relief should be innovated; secondly, military and civilian organizations should be coordinated; thirdly, professional rescue force should he strengthened; fourthly, supporting

    Objectives To identify trends in concurrent use of a benzodiazepine and an opioid and to identify the impact of these trends on admissions to hospital and emergency room visits for opioid overdose.Design Retrospective analysis of claims data, 2001-13.Setting Administrative health claims database.Participants 315 428 privately insured people aged 18-64 who were continuously enrolled in a health plan with medical and pharmacy benefits during the study period and who also filled at least one prescription for an opioid.Interventions Concurrent benzodiazepine/opioid use, defined as an overlap of at least one day in the time periods covered by prescriptions for each drug. Main outcome measures Annual percentage of opioid users with concurrent benzodiazepine use; annual incidence of visits to emergency room and inpatient admissions for opioid overdose.Results 9% of opioid users also used a benzodiazepine in 2001, increasing to 17% in 2013 (80% relative increase). This increase was driven mainly by increases among intermittent, as opposed to chronic, opioid users. Compared with opioid users who did not use benzodiazepines, concurrent use of both drugs was associated with an increased risk of an emergency room visit or inpatient admission for opioid overdose (adjusted odds ratio 2.14, 95% confidence interval 2.05 to 2.24; Pbenzodiazepine/opioid use could reduce the risk of emergency room visits related to opioid use and inpatient admissions for opioid overdose by an estimated 15% (95% confidence interval 14 to 16).Conclusions From 2001 to 2013, concurrent benzodiazepine/opioid use sharply increased in a large sample of privately insured patients in the US and significantly contributed to the overall population risk of opioid overdose.

    This is an update of a review first published in 2003 and updated in 2012.Ketamine is a commonly used anaesthetic agent, and in subanaesthetic doses is also given as an adjuvant to opioids for the treatment of refractory cancer pain, when opioids alone or in combination with appropriate adjuvant analgesics prove to be ineffective. Ketamine is known to have psychomimetic (including hallucinogenic), urological, and hepatic adverse effects. To determine the effectiveness and adverse effects of ketamine as an adjuvant to opioids for refractory cancer pain in adults. For this update, we searched MEDLINE (OVID) to December 2016. We searched CENTRAL (CRSO), Embase (OVID) and two clinical trial registries to January 2017. The intervention considered by this review was the addition of ketamine, given by any route of administration, in any dose, to pre-existing opioid treatment given by any route and in any dose, compared with placebo or active control. We included studies with a group size of at least 10 participants who completed the trial. Two review authors independently assessed the search results and performed 'Risk of bias' assessments. We aimed to extract data on patient-reported pain intensity, total opioid consumption over the study period; use of rescue medication; adverse events; measures of patient satisfaction/preference; function; and distress. We also assessed participant withdrawal (dropout) from trial. We assessed the quality of the evidence using GRADE (Grading of Recommendations Assessment, Development and Evaluation). One new study (185 participants) was identified by the updated search and included in the review. We included a total of three studies in this update.Two small studies, both with cross-over design, with 20 and 10 participants respectively, were eligible for inclusion in the original review. One study with 20 participants examined the addition of intrathecal ketamine to intrathecal morphine, compared with intrathecal morphine alone. The

  6. The Useage of Opioids and their Adverse Effects in Gastrointestinal Practice: A Review

    2013-01-01

    Opium is one of the oldest herbal medicines currently used as an analgesic, sedative and antidiarrheal treatment. The effects of opium are principally mediated by the μ-, κ- and δ-opioid receptors. Opioid substances consist of all natural and synthetic alkaloids that are derived from opium. Most of their effects on gastrointestinal motility and secretion result from suppression of neural activity. Inhibition of gastric emptying, increase in sphincter tone, changes in motor patterns, and blockage of peristalsis result from opioid use. Common adverse effects of opioid administration include sedation, dizziness, nausea, vomiting, constipation, dependency and tolerance, and respiratory depression. The most common adverse effect of opioid use is constipation. Although stool softeners are frequently used to decrease opioid-induced bowel dysfunction, however they are not efficacious. Possibly, the use of specific opioid receptor antagonists is a more suitable approach. Opioid antagonists, both central and peripheral, could affect gastrointestinal function and visceromotor sensitivity, which suggests an important role for endogenous opioid peptides in the control of gastrointestinal physiology. Underlying diseases or medications known to influence the central nervous system (CNS) often accelerate the opioid’s adverse effects. However, changing the opioid and/or route of administration could also decrease their adverse effects. Appropriate patient selection, patient education and discussion regarding potential adverse effects may assist physicians in maximizing the effectiveness of opioids, while reducing the number and severity of adverse effects.

Five hundred and six patients who completed previous studies with buprenorphine buccal film (n=445; rollover patients or were recruited de novo for this study (n=61 were enrolled in this study. All patients underwent a dose titration period of ≤6 weeks, during which doses of buprenorphine buccal film were adjusted to a maximum 900 µg every 12 hours, depending on tolerability and the need for rescue medication. An optimal dose was defined as the dose that the patient found satisfactory for both pain relief and tolerability, without the need for rescue medication or with ≤2 tablets of rescue medication per day. Once the optimal dose was reached, treatment was continued for ≤48 weeks. Pain intensity was measured throughout the study using a 0–10 numerical rating scale.Results: Of 435 patients achieving an optimal dose of buprenorphine buccal film who commenced long-term treatment, 158 (36.3% completed 48 weeks of treatment. Treatment-related adverse events occurred in 116 patients (22.9% during the titration phase and 61 patients (14.0% during the long-term treatment phase, and adverse events leading to discontinuation of treatment occurred in 14 (2.8% and 14 (3.2% patients, respectively.

  9. Opioid pharmaceuticals and addiction: the issues, and research directions seeking solutions.

    Science.gov (United States)

    Walwyn, Wendy M; Miotto, Karen A; Evans, Christopher J

    2010-05-01

    There are few pharmaceuticals superior to opiates for the treatment of pain. However, with concerns of addiction, withdrawal and questionable efficacy for all types of pain, these compounds are far from a magical panacea for pain-relief. As it is unlikely that other classes of compounds will supersede the opioids in the very near future, it is important to both optimize current opioid therapies and curb the astounding diversion of opioids from their intended analgesic use to non-medical abuse. In optimizing opioid therapeutics it is necessary to enhance the clinical awareness of the benefits of treating pain and combine this with aggressive strategies to reduce diversion for non-medical use. At the heart of the issue of opioid misuse is the role of opioid systems in the reward circuitry, and the adaptive processes associated with repetitive opioid use that manifest during withdrawal. Emerging pharmacological insights of opioid receptors will be reviewed that provide future hope for developing opioid-based analgesics with reduced addictive properties and perhaps, reduced opponent processes. In addition, with the increased understanding of nociceptive circuitry and the molecules involved in transmitting pain, new therapeutic targets have become evident that may result in effective analgesics either alone or in combination with current opioid therapies.

    2016-06-01

    We report a case of survival of a completely buried avalanche victim after being located with the radar-based RECCO Rescue System. In the winter of 2015, 2 off-piste skiers were completely buried in an avalanche near the secured ski area in Baqueira Beret, Spain. The first victim was located with the RECCO Rescue System in less than 35 minutes and was alive and conscious at extrication. This system emits radio waves and requires a specific reflector. It is a portable device that is used by more than 600 rescue organizations worldwide, especially in secured ski areas. The device should be brought to the avalanche site together with electronic avalanche transceivers, a probing team, and avalanche dogs. In the hands of experienced professionals, the device may allow rapid location of victims not carrying an electronic avalanche transceiver. Although it is not the first successful extrication of a victim with the RECCO Rescue System, it is the first case published in the medical literature and is intended to encourage data collection and to increase our understanding of the effectiveness of this device in avalanche rescue.

    The proteins that mediate the analgesic and other effects of opioid drugs and endogenous opioid peptides are known as opioid receptors. Opioid receptors consist of a family of four closely-related proteins belonging to the large superfamily of G-protein coupled receptors. The three types of opioid receptors shown unequivocally to mediate analgesia in animal models are the mu (MOR), delta (DOR), and kappa (KOR) opioid receptor proteins. The role of the fourth member of the opioid receptor fami...

  14. The rule of rescue.

    McKie, John; Richardson, Jeff

    2003-06-01

    Jonsen coined the term "Rule of Rescue"(RR) to describe the imperative people feel to rescue identifiable individuals facing avoidable death. In this paper we attempt to draw a more detailed picture of the RR, identifying its conflict with cost-effectiveness analysis, the preference it entails for identifiable over statistical lives, the shock-horror response it elicits, the preference it entails for lifesaving over non-lifesaving measures, its extension to non-life-threatening conditions, and whether it is motivated by duty or sympathy. We also consider the measurement problems it raises, and argue that quantifying the RR would probably require a two-stage procedure. In the first stage the size of the individual utility gain from a health intervention would be assessed using a technique such as the Standard Gamble or the Time Trade-Off, and in the second the social benefits arising from the RR would be quantified employing the Person Trade-Off. We also consider the normative status of the RR. We argue that it can be defended from a utilitarian point of view, on the ground that rescues increase well-being by reinforcing people's belief that they live in a community that places great value upon life. However, utilitarianism has long been criticised for failing to take sufficient account of fairness, and the case is no different here: fairness requires that we do not discriminate between individuals on morally irrelevant grounds, whereas being "identifiable" does not seem to be a morally relevant ground for discrimination.

    Loreck, David; Brandt, Nicole J; DiPaula, Bethany

    2016-04-01

    Opioid use disorder is a public health epidemic. There is increasing attention being given to opioid abuse and overdose in the United States. The overall use of illicit substances by older adults is on the rise and in part can be attributed to the aging of Baby Boomers. Furthermore, much attention is being given to prescription opioid drug overdose, but it is important to note that heroin-related deaths have also increased sharply. Heroin use is part of a larger substance abuse problem, with more than nine in 10 individuals who use heroin also using at least one other drug (e.g., cocaine, prescription opioid medication). The current article highlights treatment approaches, namely buprenorphine, buprenorphine/naloxone, and naltrexone; insurance considerations; and resources to aid in understanding and managing this public health crisis.

  17. Variation in opioid prescribing patterns between ED providers.

    2016-12-01

    Abuse of opioid prescription drugs has become an epidemic across the developed world. Despite the fact that emergency physicians overall account for a small proportion of total opioids prescribed, the number of prescriptions has risen dramatically in the past decade and, to some degree, contributes to the available supply of opioids in the community, some of which are diverted for non-medical use. Since successfully reducing opioid prescribing on the individual level first requires knowledge of current prescribing patterns, we sought to determine to what extent variation exists in opioid prescribing patterns at our institution. This was a single-institution observational study at a community hospital with an annual ED volume of 47,000 visits. We determined the number of prescriptions written by each provider, both total number and accounting for the number of patients seen. Our primary outcome measure was the level of variation at the physician level for number of prescriptions written per patient. We also identified the mean number of pills written per prescription. We analyzed data from November 13, 2014 through July 31, 2015 for 21 full-time providers. There were a total of 2211 prescriptions for opioids written over this time period for a total of 17,382 patients seen. On a per-patient basis, the rate of opioid prescriptions written per patient during this period was 127 per 1000 visits (95 % CI 122-132). There was a variation on the individual provider level, with rates ranging from 33 per to 332 per 1000 visits. There was also substantial variation by provider in the number of pills written per prescription with coefficient of variation (standard deviation divided by mean) averaged over different opioids ranging from 16 to 40 %. There was significant variation in opioid prescribing patterns at the individual physician level, even when accounting for the number of patients seen.

    Nonmedical use of opioid medications constitutes a serious health threat as the rates of addiction, overdoses, and deaths have risen in recent years. Increasingly, inappropriate and excessively liberal prescribing of opioids by physicians is understood to be a central part of the crisis. Public health officials, hospital systems, and legislators are developing programs and regulations to address the problem in sustained and systematic ways that both insures effective treatment of pain and appropriate limits on the availability of opioids. Three approaches have obtained prominence as means of avoiding excessive and inappropriate prescribing, including: providing financial incentives to physicians to change their clinical decision through pay-for-performance contracts, monitoring patient medications through Prescription Drug Monitoring Programs, and educational outreach to physicians. A promising approach to educational outreach to physicians is an intervention known as "academic detailing." It was developed in the 1980s to provide one-on-one educational outreach to physicians using similar methods as the pharmaceutical industry that sends "detailers" to market their products to physician practices. Core to academic detailing, however, is the idea that medical decisions should be based on evidence-based information, including managing conditions with updated assessment measures, behavioral, and nonpharmacological interventions. With the pharmaceutical industry spending billions of dollars to advertise their products, individual practitioners can have difficulty gathering unbiased information, especially as the number of approved medications grows each year. Academic detailing has successfully affected the management of health conditions, such as atrial fibrillation, chronic obstructive pulmonary disease, and recently, has targeted physicians who prescribe opioids. This article discusses the approach as a potentially effective preventative intervention to address the

    Opioid analgesics are commonly used to manage moderate to severe pain. However, the long-term use of opioids could lead to opioid tolerance (OT) and opioid-induced hyperalgesia (OIH). Distinguishing OIH from OT would impact the practice of opioid therapy because opioid dose adjustment may differentially influence OT and OIH. Currently, there are no standard criteria of OT versus OIH causing considerable ambiguity in clinical interpretation and management of these conditions. The authors designed a practitioner-based survey consisting of 20 targeted questions. Answering these questions would require responders' actual clinical experiences with opioid therapy. The survey was conducted between 2011 and 2012 through direct mails or e-mails to 1,408 physicians who are currently practicing in the United States. The authors find that certain clinical characteristics (eg, increased pain despite opioid dose escalation) are often used by practitioners to make differential diagnosis of OT and OIH despite some overlap in their clinical presentation. A key difference in clinical outcome is that OT and OIH could be improved and exacerbated by opioid dose escalation, respectively. Our survey results revealed a significant knowledge gap in some responders regarding differential diagnosis and management of OT and OIH. The results also identified several issues, such as opioid dose adjustment and clinical comorbidities related to OT and OIH, which require future patient-based studies.

    The aim of this project was to develop a proof-of-concept Stirling engine and heat cell for use in the mining industry, primarily for underground applications. In particular, the Stirling engine, being an external combustion engine, offers the potential to operate on stored heat in low-oxygen or inert underground atmospheres. This makes it attractive for rescue vehicles, which are required to operate in such environments. A prototype Stirling engine with power output in the 15kW range was constructed and tested. Experimental measurements showed that this output was not achieved. While the basic thermodynamic principles of the design were valid, achieved output was well below the required value. The conclusion is that, because of the lack of commercial Stirling cycle-based products and the difficulty experienced in this project in overcoming the problem of high temperature seal implementation to produce a working prototype, the short term potential of the Stirling engine for mine rescue applications is limited.

    Use of multiple pharmacies concurrently (pharmacy shopping) and overlapping prescriptions may be indicators of potential misuse or abuse of prescription opioid medications. To evaluate strategies for identifying patients at high risk, we first compared different definitions of pharmacy shopping and then added the indicator of overlapping opioid prescriptions. We identified a cohort of 90,010 Medicaid enrollees who used ≥ 3 opioid prescriptions for ≥ 90 days during 2008 to 2010 from a multistate Medicaid claims database. We compared the diagnostic odds ratios for opioid overdose events of 9 pharmacy shopping definitions. Within a 90-day interval, a threshold of 4 pharmacies had the highest diagnostic odds ratio and was used to define pharmacy shopping. The overdose rate was higher in the subgroup with overlapping prescriptions (18.5 per 1,000 person-years [PYs]) than in the subgroup with pharmacy shopping as the sole indicator (10.7 per 1,000 PYs). Among the subgroup with both conditions, the overdose rate was 26.3 per 1,000 PYs, compared with 4.3 per 1,000 PYs for those with neither condition. Overlapping opioid prescriptions and pharmacy shopping measures had adjusted hazard ratios of 3.0 and 1.8, respectively, for opioid overdose. Using these measures will improve accurate identification of patients at highest risk of opioid overdose, the first step in implementing targeted prevention policies. Long-term prescription opioid use may lead to adverse events, including overdose. Both pharmacy shopping and overlapping opioid prescriptions are associated with adverse outcomes. This study demonstrates that using both indicators will better identify those at high risk of overdose. Published by Elsevier Inc.

    2017-01-01

    Abstract Objective To advise physicians on which treatment options to recommend for specific patient populations: abstinence-based treatment, buprenorphine-naloxone maintenance, or methadone maintenance. Sources of information PubMed was searched and literature was reviewed on the effectiveness, safety, and side effect profiles of abstinence-based treatment, buprenorphine-naloxone treatment, and methadone treatment. Both observational and interventional studies were included. Main message Both methadone and buprenorphine-naloxone are substantially more effective than abstinence-based treatment. Methadone has higher treatment retention rates than buprenorphine-naloxone does, while buprenorphine-naloxone has a lower risk of overdose. For all patient groups, physicians should recommend methadone or buprenorphine-naloxone treatment over abstinence-based treatment (level I evidence). Methadone is preferred over buprenorphine-naloxone for patients at higher risk of treatment dropout, such as injection opioid users (level I evidence). Youth and pregnant women who inject opioids should also receive methadone first (level III evidence). If buprenorphine-naloxone is prescribed first, the patient should be promptly switched to methadone if withdrawal symptoms, cravings, or opioid use persist despite an optimal buprenorphine-naloxone dose (level II evidence). Buprenorphine-naloxone is recommended for socially stable prescription oral opioid users, particularly if their work or family commitments make it difficult for them to attend the pharmacy daily, if they have a medical or psychiatric condition requiring regular primary care (level IV evidence), or if their jobs require higher levels of cognitive functioning or psychomotor performance (level III evidence). Buprenorphine-naloxone is also recommended for patients at high risk of methadone toxicity, such as the elderly, those taking high doses of benzodiazepines or other sedating drugs, heavy drinkers, those with a lower

    Adults with mood disorders frequently use prescription opioids. The factors associated with this increased use remain unclear. We used the Medical Expenditure Panel Surveys from 2005 to 2011 to measure the association of mood disorders with new opioid use and the transition to longer-term opioid use for a variety of pain conditions before and after controlling for patient characteristics and clinical disability. We analyzed 33,450 adults with likely acute or potentially chronic pain conditions who were not using opioids at baseline. Among respondents with likely acute pain conditions, those with mood disorders initiated opioids more frequently for that pain condition compared with those without mood disorders (19.3%, vs 17.2%, P = 0.01). After initiation, they also transitioned to longer-term opioid therapy more frequently (11.7% vs 5.3%, P new opioid use for likely acute (adjusted odds ratio [aOR] 1.05 [0.92-1.20]) or potentially chronic pain (aOR 0.91 [0.80-1.03]). However, there remained a strong association between mood disorders and the transition to longer-term opioid use for likely acute (aOR 1.77 [1.15-2.72]) and potentially chronic pain (aOR 1.95 [1.42-2.68]). Targeting the transition to longer-term opioid use may help clinicians reduce potentially inappropriate opioid prescriptions in this high-risk population.

    Opioid prescribing for chronic noncancer pain is increasing, but there is limited knowledge about longer-term outcomes of people receiving opioids for conditions such as back pain. This study aimed to explore the relationship between prescribed opioids and disability among patients consulting in primary care with back pain. A total of 715 participants from a prospective cohort study, who gave consent for review of medical and prescribing records and completed baseline and 6month follow-up questionnaires, were included. Opioid prescription data were obtained from electronic prescribing records, and morphine equivalent doses were calculated. The primary outcome was disability (Roland-Morris Disability Questionnaire [RMDQ]) at 6months. Multivariable linear regression was used to examine the association between opioid prescription at baseline and RMDQ score at 6months. Analyses were adjusted for potential confounders using propensity scores reflecting the probability of opioid prescription given baseline characteristics. In the baseline period, 234 participants (32.7%) were prescribed opioids. In the final multivariable analysis, opioid prescription at baseline was significantly associated with higher disability at 6-month follow-up (Pback pain patients at 6-month follow-up. Further research may help us to understand the mechanisms underlying these findings and inform clinical decisions regarding the usefulness of opioids for back pain.

    Many providers report lack of confidence in managing patients with chronic pain. Thus, the primary aim of this study was to investigate the associations of provider confidence in managing chronic pain with their practice behaviors and demographics. The primary outcome measure was the results of the Opioid Therapy Provider Survey, which was administered to clinicians attending a pain-focused continuing medical education conference. Nonparametric correlations were assessed using Spearman's rho. Of the respondents, 55.0% were women, 92.8% were white, and 56.5% were physicians. Primary care providers accounted for 56.5% of the total respondents. The majority of respondents (60.8%) did not feel confident managing patients with chronic pain. Provider confidence in managing chronic pain was positively correlated with 1) following an opioid therapy protocol (P=0.001), 2) the perceived ability to identify patients at risk for opioid misuse (P=0.006), and 3) using a consistent practice-based approach to improve their comfort level with prescribing opioids (Pconfidence was negatively correlated with the perception that treating pain patients was a "problem in my practice" (P=0.005). In this study, the majority of providers did not feel confident managing chronic pain. However, provider confidence was associated with a protocolized and consistent practice-based approach toward managing opioids and the perceived ability to identify patients at risk for opioid misuse. Future studies should investigate whether provider confidence is associated with measurable competence in managing chronic pain and explore approaches to enhance appropriate levels of confidence in caring for patients with chronic pain.

    INTRODUCTION: In the prehospital setting opioid overdose is often treated with naloxone. In our physician-based medical emergency care unit (MECU) we have adopted a discharge-on-scene policy, where patients are released on scene if no residual signs of opioid intoxication are found after treatment....... The aim of this study was to describe our experience with the discharge-on-scene policy used during a 10-year-period with focus on the frequency of rebound opioid toxicity. METHODS: Data were prospectively recorded in our MECU database and we reviewed all cases of opioid overdose between 1994 and 2003....... The MECU database was cross-referenced with the Central Personal Registry. For patients who died within 48 h of MECU contact we reviewed the forensic autopsy reports to establish whether rebound opioid toxicity was likely. RESULTS: We found 4762 cases of acute opioid overdose. In 3245 cases positive...

    Recovery from obstetrics and gynecology (OB/GYN) surgery, including hysterectomy and cesarean section delivery, aims to restore function while minimizing hospital length of stay (LOS) and medical expenditures. Our analyses compare OB/GYN surgery patients who received combination intravenous (IV) acetaminophen and IV opioid analgesia with those who received IV opioid-only analgesia and estimate differences in LOS, hospitalization costs, and opioid consumption. We performed a retrospective analysis of the Premier Database between January 2009 and June 2015, comparing OB/GYN surgery patients who received postoperative pain management with combination IV acetaminophen and IV opioids with those who received only IV opioids starting on the day of surgery and continuing up to the second postoperative day. We performed instrumental variable 2-stage least-squares regressions controlling for patient and hospital covariates to compare the LOS, hospitalization costs, and daily opioid doses (morphine equivalent dose) of IV acetaminophen recipients with that of opioid-only analgesia patients. We identified 225 142 OB/GYN surgery patients who were eligible for our study of whom 89 568 (40%) had been managed with IV acetaminophen and opioids. Participants averaged 36 years of age and were predominantly non-Hispanic Caucasians (60%). Multivariable regression models estimated statistically significant differences in hospitalization cost and opioid use with IV acetaminophen associated with $484.4 lower total hospitalization costs (95% CI = -$760.4 to -$208.4; P = 0.0006) and 8.2 mg lower daily opioid use (95% CI = -10.0 to -6.4), whereas the difference in LOS was not significant, at -0.09 days (95% CI = -0.19 to 0.01; P = 0.07). Compared with IV opioid-only analgesia, managing post-OB/GYN surgery pain with the addition of IV acetaminophen is associated with decreased hospitalization costs and reduced opioid use.

    This study compared the risks of opioid shopping behavior and opioid abuse between tapentadol immediate release and oxycodone immediate release and, to validate the definition of shopping, examined the association between opioid shopping and opioid abuse further. This retrospective cohort study using linked dispensing and diagnosis databases followed opioid-naive patients for development of shopping behavior and/or opioid abuse during 1 year after initial exposure to tapentadol or oxycodone. Shopping was defined by having overlapping opioid prescriptions from >1 prescriber filled at ≥3 pharmacies; abuse by having International Classification of Diseases, 9th revision diagnoses reflecting opioid abuse, addiction, or dependence. To determine their association, we cross-tabulated shopping and opioid abuse and calculated odds ratios. Risks of developing each outcome were estimated using logistic regression. Among 277,401 participants initiating opioid use with tapentadol (39,524) or oxycodone (237,877), 0.6% developed shopping behavior, 0.75% developed abuse. Higher proportions of patients in the oxycodone group developed shopping behavior and abuse than in the tapentadol group (shopping: adjusted odds ratio [95% confidence interval], 0.45 [0.36-0.55]; abuse: 0.44 [0.37-0.54]). Shopping behavior and abuse were associated; of those with shopping behavior, 6.5% had abuse. Age (18 to 64 y), sex (male), prior benzodiazepine use, paying cash, and history (mood disorders, abuse of nonopioid medications, and back pain) were risk factors for developing either outcome. Shopping behavior and abuse measure complementary, but associated, constructs, which further validates the current definition of shopping. The risk of developing either is lower among patients who initiate opioid use with tapentadol than those who initiate opioid use with oxycodone.

  12. Suicidal ideation is associated with individual differences in prescription opioid craving and cue-reactivity among chronic pain patients.

    Given that chronic pain patients experience significant rates of suicidal ideation and suicide attempts, access to prescription opioids compounds the risk of death by suicide. These patients may experience heightened opioid craving and exhibit increased cue-reactivity to stimuli associated with past opioid use when suicidal ideation produces negative affective states. Because both opioids and suicidal behavior are used to alleviate emotional and physical pain through a process of negative reinforcement, elucidating factors that mediate this association may yield insight into suicide risk among chronic pain patients. This study examined the relationship between suicidal ideation and opioid craving and cue-reactivity, and tested opioid self-medication as a mediator of associations between those factors after controlling for the impact of pain severity. A sample of 115 chronic pain patients provided demographic and clinical information on the Obsessive Compulsive Drug Use Scale, the Current Opioid Misuse Measure, and the Brief Pain Inventory before completing an opioid dot probe task in which heart rate variability was recorded. As hypothesized, suicidal ideation was positively correlated with subjective opioid craving and physiological cue-reactivity. Self-medication significantly mediated the association between suicidal ideation, craving, and cue-reactivity. As opioids relieve the emotional pain linked with suicidal thoughts, chronic pain patients with higher levels of suicidal ideation may experience more intense opioid craving and exhibit heightened physiological cue-reactivity when compared to patients with low levels of suicidal ideation.

    Pain management has been considered as significant contributor to broad quality-of-life improvement for cancer patients. Modulating serum cholesterol levels affects analgesia abilities of opioids, important pain killer for cancer patients, in mice system. Thus the correlation between opioids usages and cholesterol levels were investigated in human patients with lung cancer. Medical records of 282 patients were selected with following criteria, 1) signed inform consent, 2) full medical records on total serum cholesterol levels and opioid administration, 3) opioid-naïve, 4) not received/receiving cancer-related or cholesterol lowering treatment, 5) pain level at level 5-8. The patients were divided into different groups basing on their gender and cholesterol levels. Since different opioids, morphine, oxycodone, and fentanyl, were all administrated at fixed low dose initially and increased gradually only if pain was not controlled, the percentages of patients in each group who did not respond to the initial doses of opioids and required higher doses for pain management were determined and compared. Patients with relative low cholesterol levels have larger percentage (11 out of 28 in female and 31 out of 71 in male) to not respond to the initial dose of opioids than those with high cholesterol levels (0 out of 258 in female and 8 out of 74 in male). Similar differences were obtained when patients with different opioids were analyzed separately. After converting the doses of different opioids to equivalent doses of oxycodone, significant correlation between opioid usages and cholesterol levels was also observed. Therefore, more attention should be taken to those cancer patients with low cholesterol levels because they may require higher doses of opioids as pain killer.

    An unintended consequence of extended-release (ER) and long-acting (LA) prescription opioids is that these formulations can be more attractive to abusers than immediate-release (IR) formulations. The US Food and Drug Administration recognized these risks and approved the ER/LA Opioid Analgesic Risk Evaluation and Mitigation Strategy (ER/LA REMS), which has a goal of reducing opioid misuse and abuse and their associated consequences. The primary objective of this analysis is to determine whether ER/LA REMS implementation was associated with decreased reports of misuse and abuse. Data from the Researched Abuse, Diversion and Addiction-Related Surveillance (RADARS(R)) System Poison Center Program were utilized. Poison center cases are assigned a reason for exposure, a medical outcome, and a level of health care received. Rates adjusted for population and drug utilization were analyzed over time. RADARS System Poison Center Program data indicate a notable decrease in ER/LA opioid rates of intentional abuse and misuse as well as major medical outcomes or hospitalizations following implementation of the ER/LA REMS. While similar decreases were observed for the IR prescription opioid group, the decreasing rate for the ER/LA opioids exceeded the decreasing rates for the IR prescription opioids and was distinctly different than that for the prescription stimulants, indicating that the ER/LA REMS program may have had an additional effect on decreases in opioid abuse and intentional misuse beyond secular trends.

    2017-03-02

     The objective of this project was to develop core competencies for education on opioids and addiction to be used in all Pennsylvania medical schools.  The Pennsylvania Physician General created a task force that was responsible for the creation of the core competencies. A literature review was completed, and a survey of graduating medical students was conducted. The task force then developed, reviewed, and approved the core competencies.  The competencies were grouped into nine domains: understanding core aspects of addiction; patient screening for substance use disorder; proper referral for specialty evaluation and treatment of substance use disorder; proper patient assessment when treating pain; proper use of multimodal treatment options when treating acute pain; proper use of opioids for the treatment of acute pain (after consideration of alternatives); the role of opioids in the treatment of chronic noncancer pain; patient risk assessment related to the use of opioids to treat chronic noncancer pain, including the assessment for substance use disorder or increased risk for aberrant drug-related behavior; and the process for patient education, initiation of treatment, careful patient monitoring, and discontinuation of therapy when using opioids to treat chronic noncancer pain. Specific competencies were developed for each domain.  These competencies will be incorporated into the educational process at all Pennsylvania medical schools. It is hoped that these curriculum changes will improve student knowledge and attitudes in these areas, thus improving patient outcomes.

    The current epidemic of prescription opioid abuse and misuse in the United States is discussed, with an emphasis on the pharmacist's role in ensuring safe and effective opioid use. U.S. sales of prescription opioids increased fourfold from 1999 to 2010, with an alarming rise in deaths and emergency department visits associated with the use of fentanyl, hydrocodone, oxycodone, and other opioid medications. Signs and symptoms of opioid toxicity may include altered mental status, hypoventilation, decreased bowel motility, central nervous system and respiratory depression, peripheral vasodilation, pulmonary edema, hypotension, bradycardia, and seizures. In patients receiving long-term opioid therapy for chronic pain, urine drug testing is an important tool for monitoring and assessment of therapy; knowledge of opioid metabolic pathways and assay limitations is essential for appropriate use and interpretation of screening and confirmatory tests. In recent years, there has been an increase in federal enforcement actions against pharmacies and prescription drug wholesalers involved in improper opioid distribution, as well as increased reliance on state-level prescription drug monitoring programs to track patterns of opioid use and improper sales. Pharmacies are urged to implement or promote appropriate guidelines on opioid therapy, including the use of pain management agreement plans; policies to ensure adequate oversight of opioid prescribing, dispensing, and waste disposal; and educational initiatives targeting patients as well as hospital and pharmacy staff. Pharmacists in hospitals and health systems can play a key role in recognizing the various forms of opioid toxicity and in preventing inappropriate prescribing and diversion of opioids.

    There is general agreement about the need to perform a screening test to assess the risk of opioid misuse prior to starting a long-term opioid treatment for chronic noncancer pain. The evidence supporting the effectiveness of opioid long-term treatment is weak, and no predictors of its usefulness have been assessed. The aim of this study was to assess the effect on pain and quality of life of chronic opioid treatment, and detect the possible predictors of its effectiveness. This observational, prospective study was conducted in 2 Italian Pain Relief Units on 77 patients affected by intractable chronic pain. Patients were submitted to psycho-logical tests, investigating the individual pain experience, risk of opioid misuse, mood states, quality of life, and personality characteristics prior to starting treatment and at 2,4, and 6-month follow-up. Both maximum and habitual pain, as measured with VAS, underwent a statistically significant reduction at 2, 4, and 6-month follow-up. In multivariate analysis, lower scores in the Pain Medication Questionnaire (PMQ) were predictive of a major reduction in maximum VAS (P = 0.005). Both low PMQ and MMPI-cynicism scores were predictive of habitual VAS decrease (P = 0.012 and P = 0.028, respectively). The results indicate that pain relief significantly improved over a 6-month period of opioid treatment, together with quality of life. The outcome was better in patients with a pretreatment low risk of opioid misuse, low scores in the Cynicism scale of MMPI-2, and no aberrant drug behaviors at follow-up. Therefore, a psychological screening and support is crucial for a good outcome of opioid therapy for chronic noncancer pain patients.

    Opioids are broad spectrum analgesics that are an integral part of the therapeutic armamentarium to combat pain in the palliative care population. Unfortunately, among the adverse effects of opioids that may be experienced along with analgesia is nausea, vomiting, and/or retching. Although it is conceivable that in the future, using combination agents (opioids combined with agents which may nullify emetic effects), currently nausea/vomiting remains a significant issue for certain patients. However, there exists potential current strategies that may be useful in efforts to diminish the frequency and/or intensity of opioid-induced nausea/vomiting (OINV).

    The United States is facing a major crisis with the current opioid epidemic. Tens of thousands of individuals are dying each year due to abuse and misuse of heroin and prescription opiate drugs. Nurses play an integral role in these aspects of health care and offer solutions by providing education; preventive measures; treatments, including medication-assisted treatments (MATs); and ongoing recovery options for individuals with opioid use disorders. Nurses provide education, issue prescriptions and dispense medications, and provide overall physical and mental health care to patients struggling with this "disease of the brain," and with the signing of the Comprehensive Addiction and Recovery Act, advanced practice RNs will soon be able to include MATs related to buprenorphine as part of their treatment plan. The current article explores the anatomy, physiology, and genetics of addiction and how they relate to the pharmacological MATs used to treat opioid use disorders.

    Prescription opioid medications are the most commonly implicated substances in unintentional overdoses. Outpatient health care encounters represent a potential opportunity to intervene to reduce opioid overdose risk. This study assessed the timing and type of outpatient provider contacts prior to death from unintentional prescription opioid overdose. This study examined all adult patients nationally in the Veterans Health Administration (VHA) who died from unintentional prescription opioid overdose in fiscal years 2004-2007 and who used VHA services anytime within two years of their deaths (N=1,813). For those whose final treatment contact was in an outpatient setting (N=1,457), demographic, clinical, and treatment characteristics were compared among patients categorized by the location of their last contact. Among individuals last seen in outpatient settings, 33% were seen within one week of their overdose and 62% within one month of their overdose. A substantial proportion of patients (30%) were last seen within one month of death in mental health or substance use disorder outpatient settings. The majority of patients (86%) did not fill an opioid prescription on their last outpatient visit prior to death from unintentional opioid overdose. Most patients who died by unintentional prescription opioid overdose were seen in outpatient settings within a month of their overdose. These settings may provide an opportunity to prevent patients from dying from prescription opioid overdoses. Interventions to reduce risk should not be limited to visits during which an opioid is prescribed.

    This study reports the results of a researcher-administered survey with 115 patients receiving chronic opioid therapy (>90 days) to obtain information regarding how chronic opioid therapy was started. Chronic opioids were started after surgery (27.0%, 95% confidence interval [CI], 18.5-35.5) or for the treatment of acute injury-related pain (27.0%, 95% CI, 18.5-35.5). Many who initiated opioid therapy after surgery reported postoperative complications (61.3%, 95% CI, 50.8-71.8) and many with injury-related pain reported follow-up corrective surgery (58.1%, 95% CI, 47.5-68.7), which led to the continuation of opioids. A large percentage of patients had concurrent depression (43.5%, 95% CI, 34.0-53.0) and anxiety (23.5%, 95% CI, 15.3-31.7). Many participants had a medical history of aberrant drug-related behavior (32.5%, 95% CI, 23.5-41.5) and self-reported history of addiction (21.7%, 95% CI, 13.7-29.7). Almost one-quarter reported taking opioids for a different indication than that for which opioids were started (95% CI, 26.6-45.0). Patients receiving long-term opioid therapy often transitioned to chronic use after starting opioids for the short-term treatment of postoperative or injury-related pain. It is not evident if a clear decision to continue opioids on a chronic basis was made. This survey provides insight as to how chronic opioid therapy is started, and may suggest opportunities for improved patient selection for opioid therapy.

    Full Text Available Ashley-Nicole Carmichael,1 Laura Morgan,1 Egidio Del Fabbro2 1School of Pharmacy, 2Division of Hematology, Oncology, and Palliative Care, Virginia Commonwealth University, Richmond, VA, USA Background: The misuse and abuse of opioid medications in many developed nations is a health crisis, leading to increased health-system utilization, emergency department visits, and overdose deaths. There are also increasing concerns about opioid abuse and diversion in patients with cancer, even at the end of life. Aims: To evaluate the current literature on opioid misuse and abuse, and more specifically the identification and assessment of opioid-abuse risk in patients with cancer. Our secondary aim is to offer the most current evidence of best clinical practice and suggest future directions for research. Materials and methods: Our integrative review included a literature search using the key terms “identification and assessment of opioid abuse in cancer”, “advanced cancer and opioid abuse”, “hospice and opioid abuse”, and “palliative care and opioid abuse”. PubMed, PsycInfo, and Embase were supplemented by a manual search. Results: We found 691 articles and eliminated 657, because they were predominantly noncancer populations or specifically excluded cancer patients. A total of 34 articles met our criteria, including case studies, case series, retrospective observational studies, and narrative reviews. The studies were categorized into screening questionnaires for opioid abuse or alcohol, urine drug screens to identify opioid misuse or abuse, prescription drug-monitoring programs, and the use of universal precautions. Conclusion: Screening questionnaires and urine drug screens indicated at least one in five patients with cancer may be at risk of opioid-use disorder. Several studies demonstrated associations between high-risk patients and clinical outcomes, such as aberrant behavior, prolonged opioid use, higher morphine-equivalent daily dose

    Full Text Available Context: The dramatic rise in the use of prescription opioids to treat non-cancer pain has been paralleled by increasing prescription opioid abuse. However, detailed analyses of these trends and programs to address them are lacking.Objective: To study the association between state shipments of prescription opioids for medical use and prescription opioid abuse admissions and to assess the effects of state prescription drug monitoring programs (PDMPs on prescription opioid abuse admissions.Design and Setting: A retrospective ecological cohort study comparing state prescription opioid shipments (source: Automation of Reports and Consolidated Orders Systems database and inpatient admissions for prescription opioid abuse (source: Treatment Episode Data Set in 14 states with PDMPs (intervention group and 36 states without PDMPs (control group for the period 1997–2003.Results: From 1997 to 2003, oxycodone, morphine, and hydrocodone shipments increased by 479%, 100%, and 148% respectively. Increasing prescription oxycodone shipments were significantly associated with increasing prescription opioid admission rates (p 0.001. PDMP states had significantly lower oxycodone shipments than the control group. PDMP states had less increase in prescription opioid admissions per year (p = 0.063. A patient admitted to an inpatient drug abuse rehabilitation program in a PDMP state was less likely to be admitted for prescription opioid drug abuse (Odds ratio = 0.775, 95% Confidence Interval 0.764–0.785.Conclusions: PDMPs appear to decrease the quantity of oxycodone shipments and the prescription opioid admission rate for states with these programs. Overall, opioid shipments rose significantly in PDMP states during the study period indicating a negligible “chilling effect” on physician prescribing.

  13. Molecular mechanism for opioid dichotomy: bidirectional effect of μ-opioid receptors on P2X₃ receptor currents in rat sensory neurones.

    2015-06-01

    Here, we describe a molecular switch associated with opioid receptors-linked signalling cascades that provides a dual opioid control over P2X3 purinoceptor in sensory neurones. Leu-enkephalin inhibited P2X3-mediated currents with IC50 ~10 nM in ~25% of small nociceptive rat dorsal root ganglion (DRG) neurones. In contrast, in neurones pretreated with pertussis toxin leu-enkephalin produced stable and significant increase of P2X3 currents. All effects of opioid were abolished by selective μ-opioid receptor antagonist D-Phe-Cys-Tyr-D-Trp-Orn-Thr-Pen-Thr-NH2 (CTOP), nonselective inhibitor naloxone, and by PLC inhibitor U73122. Thus, we discovered a dual link between purinoceptors and μ-opioid receptors: the latter exert both inhibitory (pertussis toxin-sensitive) and stimulatory (pertussis toxin-insensitive) actions on P2X3 receptors through phospholipase C (PLC)-dependent pathways. This dual opioid control of P2X3 receptors may provide a molecular explanation for dichotomy of opioid therapy. Pharmacological control of this newly identified facilitation/inhibition switch may open new perspectives for the adequate medical use of opioids, the most powerful pain-killing agents known today.

    2007-08-01

    Full Text Available Abstract Background Personality traits may form a part of the aetiology of opioid dependence. For instance, opioid dependence may result from self-medication in emotionally unstable individuals, or from experimenting with drugs in sensation seekers. The five factor model (FFM has obtained a central position in contemporary personality trait theory. The five factors are: Neuroticism, Extraversion, Openness to Experience, Agreeableness and Conscientiousness. Few studies have examined whether there is a distinct personality pattern associated with opioid dependence. Methods We compared FFM personality traits in 65 opioid dependent persons (mean age 27 years, 34% females in outpatient counselling after a minimum of 5 weeks in buprenorphine replacement therapy, with those in a non-clinical, age- and sex-matched sample selected from a national database. Personality traits were assessed by a Norwegian version of the Revised NEO Personality Inventory (NEO PI-R, a 240-item self-report questionnaire. Cohen's d effect sizes were calculated for the differences in personality trait scores. Results The opioid-dependent sample scored higher on Neuroticism, lower on Extraversion and lower on Conscientiousness (d = -1.7, 1.2 and 1.7, respectively than the controls. Effects sizes were small for the difference between the groups in Openness to experience scores and Agreeableness scores. Conclusion We found differences of medium and large effect sizes between the opioid dependent group and the matched comparison group, suggesting that the personality traits of people with opioid dependence are in fact different from those of non-clinical peers.

  20. Designing Opioids That Deter Abuse

    Directory of Open Access Journals (Sweden)

    Robert B. Raffa

    2012-01-01

    Full Text Available Prescription opioid formulations designed to resist or deter abuse are an important step in reducing opioid abuse. In creating these new formulations, the paradigm of drug development target should be introduced. Biological targets relating to the nature of addiction may pose insurmountable hurdles based on our current knowledge and technology, but products that use behavioral targets seem logical and feasible. The population of opioid abusers is large and diverse so behavioral targets are more challenging than they appear at first glance. Furthermore, we need to find ways to correlate behavioral observations of drug liking to actual use and abuse patterns. This may involve revisiting some pharmacodynamic concepts in light of drug effect rather than peak concentration. In this paper we present several new opioid analgesic agents designed to resist or deter abuse using physical barriers, the inclusion of an opioid agonist or antagonist, an aversive agent, and a prodrug formulation. Further, this paper also provides insight into the challenges facing drug discovery in this field. Designing and screening for opioids intended to resist or deter abuse is an important step to meet the public health challenge of burgeoning prescription opioid abuse.

    Very little has been published on treating acute pain in children younger than the age of 3 for burns or any other trauma etiology. This study prospectively monitored the pain behavior and opioid analgesic intake of 31 pediatric burn patients (mean age = 23.71 months; SD = 15.75). Twelve of those children were randomized to conditions in which they either received opioid analgesics pro re nata (ie, as needed, pain contingent) or on a regular basis. The two groups did not show differences in demonstrable pain but, interestingly, they received equivalent does of opioid analgesics. As such, the pro re nata group was likely medicated largely on a regularly scheduled basis. For most of the remaining (nonrandomized) subjects, physicians ordered regularly scheduled opioid analgesics, suggesting that this practice has become largely institutionalized in the study setting. Information on pediatric opioid analgesic dosing and pain measurement strategies for nonverbal subjects can be derived from the findings.

    To review opioid dependence (OD) and its treatment. Pharmacologic treatments, including the use of buprenorphine/naloxone, are presented. Pharmaceutical care functions for outpatient OD treatment are discussed. Primary and review articles were identified by MEDLINE and HEALTHSTAR searches (from 1966 to November 2000) and through secondary sources. Tertiary sources were also reviewed regarding general concepts of OD and its treatment. Relevant articles were reviewed after identification from published abstracts. Articles were selected based on the objectives for this article. Studies of the treatment of OD with buprenorphine were selected based on the topic (pharmacology, pharmacokinetics, adverse reactions) and study design (randomized, controlled clinical trials in patients with OD with active/placebo comparisons and/or comparisons of active OD treatments). Articles regarding pharmacists' activities in the treatment and prevention of OD were reviewed for the pharmaceutical care section. OD is considered a medical disorder with costly adverse health outcomes. Although methadone maintenance treatment (MMT) is cost-effective for OD, only about 12% of individuals with OD receive this treatment. Psychological and pharmacologic modalities are used to treat OD, but patients often relapse. Drug therapy includes alpha 2-agonists for withdrawal symptoms, detoxification regimens with or without opioids, opioid antagonists, and opioid replacement including methadone, levomethadyl acetate, and buprenorphine. The Drug Addiction Treatment Act of 1999 allows for office-based opioid replacement therapies. Sublingual buprenorphine with naloxone can be used in this milieu. Buprenorphine with naloxone is currently under new drug application review with the Food and Drug Administration. Clinical research shows buprenorphine to be equal in effectiveness to methadone, but safer in overdose due to its ceiling effect on respiratory depression. It has lower abuse potential and fewer

    Chronic pain is a clinically relevant and yet unsolved conditions that is poorly treated with the currently available drugs, thus highlighting the urgent need of innovative analgesics. Although opiates are not very effective in the treatment of inflammatory and neuropathic pain, developing novel opioid receptor peptide agonists, as well as modulating the opioid receptor-mediated responses in a ligand-specific fashion, may represent an innovative and promising strategy to identify more efficacious and safer antalgic drugs. In this review, novel analogues of endomorphin 1 (a mu opioid receptor selective agonist able to induce analgesia in different animal models of pain - including neuropathic pain) and dermorphin (one of the most potent opioid peptide existing in nature) will be discussed as they are emerging as a promising starting point to develop novel opioid agonists: endomorphin 1 analogues, in fact, may determine antinociception in different models of neuropathic pain with reduced side effects as compared to classic opiates as morphine; dermorphin analogues may elicit analgesia in animal models of both inflammatory and neuropathic pain and with less severe adverse effects. Furthermore, such opioid peptides may allow to explore unprecedented modalities of ligand-receptor interactions, helping to characterize biased agonism at opioid receptors: exploiting functional selectivity at opioid receptor may lead to identify innovative analgesic with improved pharmacological responses and optimized side effects. Thus, innovative opioid peptides, as those outlined in this review, are promising candidates to develop more effective opioid analgesics to be employed as medications for chronic pain states, as inflammatory or neuropathic pain.

    In recent years, earthquake disaster occurred frequently in Chinese mainland, the secondary disaster which have been caused by it is more serious in mountainous region. Because of the influence of terrain and geological conditions, the difficulty of earthquake emergency rescue work greatly increased, rescue force is also urged. Yet, it has been studied less on earthquake emergency rescue in mountainous region, the research in existing equipment whether can meet the actual needs of local earthquake emergency rescue is poorly. This paper intends to discuss and solve these problems. Through the mountainous regions Ganzi and Liangshan states in Sichuan field research, we investigated the process of earthquake emergency response and the projects for rescue force after an earthquake, and we also collected and collated local rescue force based data. By consulting experts and statistical analyzing the basic data, there are mainly two problems: The first is about local rescue force, they are poorly equipped and lack in the knowledge of medical help or identify architectural structure. There are no countries to establish a sound financial investment protection mechanism. Also, rescue equipment's updates and maintenance; The second problem is in earthquake emergency rescue progress. In the complicated geologic structure of mountainous regions, traffic and communication may be interrupted by landslides and mud-rock flows after earthquake. The outside rescue force may not arrive in time, rescue equipment was transported by manpower. Because of unknown earthquake disaster information, the local rescue force was deployed unreasonable. From the above, the local government worker should analyze the characteristics of the earthquake disaster in mountainous regions, and research how to improve their earthquake emergency rescue ability. We think they can do that by strengthening and regulating the rescue force structure, enhancing the skills and knowledge, training rescue workers

    As pain is the cardinal symptom of fibromyalgia (FM), strategies directed towards pain relief are an integral component of treatment. Opioid medications comprise a category of pharmacologic treatments which have impact on pain in various conditions with best evidence for acute pain relief. Although opioid therapy other than tramadol has never been formally tested for treatment of pain in FM, these agents are commonly used by patients. We have examined the effect of opioid treatments in patients diagnosed with FM and followed longitudinally in a multidisciplinary pain center over a period of 2 years. In this first study reporting on health related measures and opioid use in FM, opioid users had poorer symptoms and functional and occupational status compared to nonusers. Although opioid users may originally have had more severe symptoms at the onset of disease, we have no evidence that these agents improved status beyond standard care and may even have contributed to a less favourable outcome. Only a formal study of opioid use in FM will clarify this issue, but until then physicians must be vigilant regarding the multiple adverse consequences of opioid therapy.

  9. Joseph Conrad's tormented Rescue (fantasy).

    Freedman, William

    2014-02-01

    Joseph Conrad was a notoriously tormented writer for whom the creative act was often a punishment severe enough to drive him into paralyzing depressions that delayed the completion of his novels, sometimes for years. By far the most agonizing of these projects was The Rescue, a novel he began in 1898, abandoned a year later, tried unsuccessfully to continue several times over the next two decades, but was only able to resume in 1918 and to complete, after another tortured two-year struggle, in 1920. An explanation for this incapacity, that is powerfully suggested by the novel's evocative title and perhaps unintentionally ironic subtitle (A Romance of the Shallows) has not yet been explored. Using Freud's 1910 essay on the rescue fantasy, "Contributions to the Psychology of Love: A Special Type of Choice of Object Made by Men," and Emanuel Berman's instructive revision and expansion of the concept in his 2003 American Imago essay, "Ferenczi, Rescue, and Utopia," I argue that a substantial explanation for Conrad's tormented history with The Rescue is ascribable to its quite remarkably faithful treatment of a rescue fantasy with deep and disabling resonance for its author. More specifically, the difficulty was compounded by the novel's dramatization of the soul-crushing conflict between two such fantasies: one in the service of the masculine ideal of unflinching dedication to a heroic purpose, the other promising satisfaction to the equally potent demands of emotional and sexual desire. Features of Conrad's narrative fit so tightly and consistently with the theory as Freud (and Abraham) proposed and as Berman elaborated it that The Rescue offers itself as one of those rare and reinforcing instances wherein the literary text seems to validate the psychoanalytic theory at least as persuasively as the theory "understands" the text.

    Full Text Available The inflammation of peripheral tissues leads the primary afferent neurons, in particular at the cell bodies level located in the DRG (dorsal root ganglia, to an increased synthesis of opioid receptors: determining an “up-regulation”. After that opioid receptors are transported at the level of the nociceptive terminals, they are incorporated into the neuronal membrane becoming functional receptors. The above receptor proteins bind to opioid produced by immune cells or the exogenous ones. This leads to a direct or indirect suppression of the Ca2+ currents induced by TRPV1 or the currents of the Na+, resulting in neuronal reduced excitability and in transmitted signals decrease. The observation that the immune system is able to modulate the pain by ligands that interact with the opioid receptors located on sensory neurons, may have broad implications for the development of innovative and safer pain drugs.

    The main aim of our work was to improve the safety of opioid use in our institution, an acute generalhospital with 620 beds. Initially, all reported opioid errors from 2001 - 2006 were audited. The findings directed a range of multidisciplinary staff educational inputs to improve opioid prescribing and administration practice, and encourage drug error reporting. 448 drug errors were reported, of which 54 (12%) involved opioids; of these, 43 (79%) involved codeine, morphine or oxycodone. 31 of the errors (57%) were associated with administration, followed by 12 (22%) with dispensing and 11 (20%) with prescribing. There were 2 reports of definite patient harm. A subsequent audit examined a 17-month period following the introduction of the above teaching: 17 errors were noted, of which 14 (83%) involved codeine, morphine or oxycodone. Again, drug administration was most error-prone, comprising 11 (65%) of reports. However, just 2 (12%) of the reported errors now involved prescribing, which was a reduction.

    The leading cause of adult injury death in the U.S.A. is drug overdose, the majority of which involves prescription opioid medications. Outside of the U.S.A., deaths by drug overdose are also on the rise, and overdose is a leading cause of death for drug users. Reducing overdose risk while maintaining access to prescription opioids when medically indicated requires careful consideration of how opioids are prescribed and dispensed, how patients use them, how they interact with other medications, and how they are safely stored. Pharmacists, highly trained professionals expert at detecting and managing medication errors and drug-drug interactions, safe dispensing, and patient counseling, are an under-utilized asset in addressing overdose in the U.S. and globally. Pharmacies provide a high-yield setting where patient and caregiver customers can access naloxone-an opioid antagonist that reverses opioid overdose-and overdose prevention counseling. This case study briefly describes and provides two US state-specific examples of innovative policy models of pharmacy-based naloxone, implemented to reduce overdose events and improve opioid safety: Collaborative Pharmacy Practice Agreements and Pharmacy Standing Orders.

  16. Impact of a Mandatory Prescription Drug Monitoring Program on Prescription of Opioid Analgesics by Dentists.

    Linda Rasubala

    Full Text Available Prescription Drug Monitoring Programs (PDMP are statewide databases that collect data on prescription of controlled substances. New York State mandates prescribers to consult the PDMP registry before prescribing a controlled substance such as opioid analgesics. The effect of mandatory PDMP on opioid drug prescriptions by dentists is not known. This study investigates the impact of mandatory PDMP on frequency and quantity of opioid prescriptions by dentists in a dental urgent care center. Based on the sample size estimate, we collected patient records of a 3-month period before and two consecutive 3-month periods after the mandatory PDMP implementation and analyzed the data on number of visits, treatment types and drug prescriptions using Chi-square tests. For patients who were prescribed pain medications, 452 (30.6%, 190 (14.1%, and 140 (9.6% received opioid analgesics in the three study periods respectively, signifying a statistically significant reduction in the number of opioid prescriptions after implementation of the mandatory PDMP (p<0.05. Total numbers of prescribed opioid pills in a 3-month period decreased from 5096 to 1120, signifying a 78% reduction in absolute quantity. Prescriptions for non-opioid analgesics acetaminophen increased during the same periods (p<0.05. We conclude that the mandatory PDMP significantly affected the prescription pattern for pain medications by dentists. Such change in prescription pattern represents a shift towards the evidence-based prescription practices for acute postoperative pain.

  17. Methadone versus buprenorphine for the treatment of opioid abuse in pregnancy: science and stigma.

    2015-01-01

    The past decade has seen an increase in rates of opioid abuse during pregnancy. This clinical challenge has been met with debate regarding whether or not illicit and prescription opioid-dependent individuals require different treatment approaches; whether detoxification is preferable to maintenance; and the efficacy of methadone versus buprenorphine as treatment options during pregnancy. The clinical recommendations resulting from these discussions are frequently influenced by the comparative stigma attached to heroin abuse and methadone maintenance versus prescription opioid abuse and maintenance treatment with buprenorphine. While some studies have suggested that a subset of individuals who abuse prescription opioids may have different characteristics than heroin users, there is currently no evidence to suggest that buprenorphine is better suited to treatment of prescription opioid abuse than methadone. Similarly, despite its perennial popularity, there is no evidence to recommend detoxification as an efficacious approach to treatment of opioid dependence during pregnancy. While increased access to treatment is important, particularly in rural areas, there are multiple medical and psychosocial reasons to recommend comprehensive substance abuse treatment for pregnant women suffering from substance use disorders rather than office-based provision of maintenance medication. Both methadone and buprenorphine are important treatment options for opioid abuse during pregnancy. Methadone may still remain the preferred treatment choice for some women who require higher doses for stabilization, have a higher risk of treatment discontinuation, or who have had unsuccessful treatment attempts with buprenorphine. As treatment providers, we should advocate to expand available treatment options for pregnant women in all States.

    Currently, most epidemiological research into the impact of opioid analgesics on road safety has focused on the association between opioid use and traffic crash occurrence. Yet, the role of opioid analgesics on crash responsibility is still not properly understood. Therefore, we examined the impact of opioid analgesics on drivers (all had a confirmed BAC=0) involved in fatal crashes (1993-2006) using a case-control design based on data from the Fatality Analysis Reporting System. Cases had one or more crash-related unsafe driving actions (UDA) recorded; controls had none. We calculated adjusted odds ratios (ORs) of any UDA by medication exposure after controlling for age, sex, other medications, and driving record. Compared to drivers who tested negative for opioid analgesics, female drivers who tested positive demonstrated increased odds of performing an UDA from ages 25 (OR: 1.35; 95% CI: 1.05; 1.74) to 55 (OR: 1.30; 95% CI: 1.07; 1.58). For male drivers this was true from ages 25 (OR: 1.66; 95% CI: 1.32; 2.09) to 65 (OR: 1.39; 95% CI: 1.17; 1.67). The detection of opioid analgesics was not associated with greater risk of an UDA for older drivers. Research is necessary to examine why these age differences exist, and if possible, to ensure that opioid analgesics do not contribute to crashes.

    Full Text Available Background: Opioid drugs are the most effective drugs for the treatment of moderate to severe pain. Rates of opioid use are influenced by a variety of factors. The aim of this study was to determine the pattern of use of parenteral opioid drugs in hospitalized patients in a referral teaching hospital. Methods: In a retrospective study, required data were extracted from medical records of adult patients who had received any parenteral opioid analgesic in the 6-month period from March 2013 to September 2013. The Anatomical Therapeutic Chemical Classification/Defined Daily Doses (ATC/DDD system method was used for evaluation of opioid analgesic use in patients.Results: The overall usage of parenteral opioid analgesics was 730.51 DDDs with meperidine (Pethidine having the most amounts of use (588.69 DDDs and 33.23 DDDs/100 bed-days. Overall, the male surgery ward and emergency department had the most amounts of use based on the number of DDDs (445.8 DDDs and per 100 bed-days (1046 DDDs/100 bed-days, respectively. Methadone use was most in the infectious diseases ward.Conclusion: The trend of parenteral opioid analgesics consumption is increasing in this hospital. Therefore, better adherence to pain treatment guidelines by medical staff is necessary for rational use of these drugs.

    Methylphenidate is a central nervous system simulant that is used for management of opioid-induced sedation. Sparse data exist regarding use patterns of methylphenidate and opioids in patients with pain. This retrospective data analysis evaluated concomitant methylphenidate and opioid use from physician-reported medication lists and in urine specimens of patients with pain. All specimens were analyzed and quantified with LC-MS-MS. Concomitant methylphenidate and opioid use (e.g., sample population) were compared with a baseline population of patients taking opioids. There were 3,326 patients with physician-reported use of methylphenidate. Of these, 1,089 patients were tested for the presence of methylphenidate in urine. Methylphenidate was positive in urine for 551 patients (detection rate of 50.6%). Ritalinic acid was positive in 776 patients (detection rate of 71.3%). The current study observed differences in the use pattern of methylphenidate based on opioid type. Physician-reported use revealed methadone had the highest percent difference between the sample and baseline populations (77%, P ≤ 0.05). Fentanyl, morphine and hydromorphone also had higher percent differences of 19.6, 25.3 and 32.3%, respectively. Further studies need to examine the apparent discrepancies between the physician-reported medication lists and urine drug testing of concomitant methylphenidate and opioid use in patients with pain.

    % did not regard opioids as drugs to help patients die, and 72% did not view them as drugs of abuse. More English (41% than German (28% nurses were afraid of criminal investigations and were constantly aware of side effects (UK, 94%; Germany, 38% when using opioids. Four latent variables were identified which likely influence nurses’ mental models: “conscious decision-making”; “medication-related fears”; “practice-based observations”; and “risk assessment”. They were predicted by strength of religious beliefs and indicators of informal learning such as experience but not by indicators of formal learning such as conference attendance. Conclusion: Nurses in both countries employ analytical and affective mental models when administering the opioids and seem to learn from experience rather than from formal teaching. Additionally, some attitudes and emotions towards opioids are likely the result of nurses’ cultural background. Keywords: nurses, opioids, mental models, decision-making

  5. It's MORe exciting than mu: crosstalk between mu opioid receptors and glutamatergic transmission in the mesolimbic dopamine system.

    Chartoff, Elena H; Connery, Hilary S

    2014-01-01

    Opioids selective for the G protein-coupled mu opioid receptor (MOR) produce potent analgesia and euphoria. Heroin, a synthetic opioid, is considered one of the most addictive substances, and the recent exponential rise in opioid addiction and overdose deaths has made treatment development a national public health priority. Existing medications (methadone, buprenorphine, and naltrexone), when combined with psychosocial therapies, have proven efficacy in reducing aspects of opioid addiction. Unfortunately, these medications have critical limitations including those associated with opioid agonist therapies (e.g., sustained physiological dependence and opioid withdrawal leading to high relapse rates upon discontinuation), non-adherence to daily dosing, and non-renewal of monthly injection with extended-release naltrexone. Furthermore, current medications fail to ameliorate key aspects of addiction such as powerful conditioned associations that trigger relapse (e.g., cues, stress, the drug itself). Thus, there is a need for developing novel treatments that target neural processes corrupted with chronic opioid use. This requires a basic understanding of molecular and cellular mechanisms underlying effects of opioids on synaptic transmission and plasticity within reward-related neural circuits. The focus of this review is to discuss how crosstalk between MOR-associated G protein signaling and glutamatergic neurotransmission leads to immediate and long-term effects on emotional states (e.g., euphoria, depression) and motivated behavior (e.g., drug-seeking, relapse). Our goal is to integrate findings on how opioids modulate synaptic release of glutamate and postsynaptic transmission via α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid and N-methyl-D-aspartate receptors in the nucleus accumbens and ventral tegmental area with the clinical (neurobehavioral) progression of opioid dependence, as well as to identify gaps in knowledge that can be addressed in future studies.

    Objective To determine what proportion of a geographically-defined population who receive new opioid prescriptions progress to episodic or chronic patterns of opioid prescribing, and to explore the clinical characteristics associated with patterns of opioid prescribing. Methods Population-based drug prescription records for the Olmsted County population between January 1 and December 31, 2009 were obtained using the Rochester Epidemiology Project medical records linkage system (n=142,377). All medical records were reviewed for a random sample of 293 patients who had a new (“incident”) prescription for an opioid analgesic in 2009. Patients were followed through their medical records for 1 year following their initial prescription date, with patterns of opioid prescribing categorized as acute, episodic, or chronic. Results Overall, 293 patients received 515 new opioid prescriptions in 2009. Of these, 61 (21%) progressed to an episodic prescribing pattern, and 19 (6%) progressed to a chronic prescribing pattern. In multivariable logistic regression analyses, substance abuse was significantly associated with a chronic opioid prescribing pattern compared to an acute prescribing pattern. Past or current nicotine use and substance abuse were significantly associated with episodic or chronic prescribing patterns compared to an acute prescribing pattern. Conclusion Knowledge of the clinical characteristics associated with the progression of an acute to an episodic or chronic prescribing pattern of opioid use could aid in the identification of at-risk patients and provide the basis for developing targeted clinical interventions.

    Environmentally caused changes in chromosomes that do not alter the DNA sequence but cause phenotypic changes by altering gene transcription are summarized as epigenetics. A major epigenetic mechanism is methylation or demethylation at CpG-rich DNA islands. DNA methylation triggered by drugs has largely unexplored therapeutic consequences. Here we report increased methylation at a CpG rich island in the OPRM1 gene coding for μ-opioid receptors and at a global methylation site (LINE-1) in leukocytes of methadone-substituted former opiate addicts compared with matched healthy controls. Higher DNA methylation associated with chronic opioid exposure was reproduced in an independent cohort of opioid-treated as compared to non-opioid-treated pain patients. This suggests that opioids may stimulate DNA methylation. The OPRM1 methylation had no immediate effect on μ-opioid receptor transcription and was not associated with opioid dosing requirements. However, the global DNA methylation at LINE-1 was significantly correlated with increased chronic pain. This suggests inhibitory effects on the transcription of still unspecified nocifensive gene products. It further implies that opioids may be causally associated with increased genome-wide DNA methylation, although currently there is no direct evidence of this. This has phenotypic consequences for pain and may provide a new, epigenetics-associated mechanism of opioid-induced hyperalgesia. The results indicate a potential influence of opioid analgesics on the patients' epigenome. They emphasize the need for reliable and cost-effective screening tools and may imply that high-throughput screening for lead compounds in artificial expression systems may not provide the best tools for identifying new pain medications.

    In Italy since the 38/2010 law concerning Palliative Care and pain therapy has been promulgated, the consumption of opioids started increasing. However, despite the availability of a large amount of data regarding opioid prescription, a database including all patients on chronic opioid therapy does not yet exist. Retrospective analysis of analgesic opioid consumption was performed between January 2013 and December 2013 using the data of national refunded medications for outpatients, collected by Italian Ministry of Health. We considered patients on chronic opioid therapy those patients with at least three opioids prescriptions in three consecutive months and/or six opioid prescriptions in six even not consecutive months in the observation period. We considered cancer patients those with neoplasm exemption code in the scheduled prescription and/or patients with at least one ROOs prescription (rapid onset opioids, approved in Italy for Break Through cancer Pain-BTcP- only). We also calculated the patient's morphine daily mean dose (MED) converting all prescribed opioids in equivalent of morphine using specific conversion tables. This census revealed a total of 422,542 patients in chronic therapy with opioids, of those 369.961 with chronic non-cancer pain and 52,581 with chronic cancer pain. This represents about 4% of the estimated requirement in Italy for both groups based on previous surveys regarding the prevalence of chronic pain. Relatively to MED, We found that in Italy chronic cancer pain patients receive doses similar to patients with cancer pain in other Literature reports, whereas patients with chronic non-cancer pain received lower dosages.

    The increasing availability of prescription opioid analgesics for the treatment of pain has been paralleled by an epidemic of opioid misuse, diversion, and overdose. The development of abuse-deterrent formulations (ADF) of conventional opioids such as oxycodone and morphine represents an advance in the field and has had a positive but insufficient impact, as most opioids are still prescribed in highly abusable, non-ADF forms, and abusers can tamper with ADF medications to liberate the abusable opioid within. The abuse liability of mu-opioid agonists appears to be dependent on their rapid rate of entry into the central nervous system (CNS) while analgesic activity appears to be a function of CNS exposure alone, suggesting that a new opioid agonist with an inherently low rate of influx across the blood-brain barrier could mediate analgesia with low abuse liability, regardless of formulation or route of administration. NKTR-181 is a novel, long-acting, selective mu-opioid agonist with structural properties that reduce its rate of entry across the blood-brain barrier compared with traditional mu-opioid agonists. NKTR-181 demonstrated maximum analgesic activity comparable to that of oxycodone in hot-plate latency and acetic acid writhing models. NKTR-181 was distinguishable from oxycodone by its reduced abuse potential in self-administration and progressive ratio break point models, with behavioral effects similar to those of saline, as well as reduced CNS side effects as measured by the modified Irwin test. The in vitro and in vivo studies presented here demonstrate that NKTR-181 is the first selective mu-opioid agonist to combine analgesic efficacy and reduced abuse liability through the alteration of brain-entry kinetics.

    Traci C Green

    Full Text Available BACKGROUND: As a population, non-medical prescription opioid users are not well-defined. We aimed to derive and describe typologies of prescription opioid use and nonmedical use using latent class analysis in an adult population being assessed for substance abuse treatment. METHODS: Latent class analysis was applied to data from 26,314 unique respondents, aged 18-70, self-reporting past month use of a prescription opioid out of a total of 138,928 cases (18.9% collected by the Addiction Severity Index-Multimedia Version (ASI-MV®, a national database for near real-time prescription opioid abuse surveillance. Data were obtained from November 2005 through December 2009. Substance abuse treatment, criminal justice, and public assistance programs in the United States submitted data to the ASI-MV database (n = 538. Six indicators of the latent classes derived from responses to the ASI-MV, a version of the ASI modified to collect prescription opioid abuse and chronic pain experience. The latent class analysis included respondent home ZIP code random effects to account for nesting of respondents within ZIP code. RESULTS: A four-class adjusted latent class model fit best and defined clinically interpretable and relevant subgroups: Use as prescribed, Prescribed misusers, Medically healthy abusers, and Illicit users. Classes varied on key variables, including race/ethnicity, gender, concurrent substance abuse, duration of prescription opioid abuse, mental health problems, and ASI composite scores. Three of the four classes (81% of respondents exhibited high potential risk for fatal opioid overdose; 18.4% exhibited risk factors for blood-borne infections. CONCLUSIONS: Multiple and distinct profiles of prescription opioid use were detected, suggesting a range of use typologies at differing risk for adverse events. Results may help clinicians and policy makers better focus overdose and blood-borne infection prevention efforts and intervention strategies

    Opioid abuse is a serious public health concern. In response, the Food and Drug Administration (FDA) determined that a risk evaluation and mitigation strategy (REMS) for extended-release and long-acting (ER/LA) opioids was necessary to ensure that the benefits of these analgesics continue to outweigh the risks. Key components of the REMS are training for prescribers through accredited continuing education (CE), and providing patient educational materials. The impact of this REMS has been assessed using diverse metrics including evaluation of prescriber and patient understanding of the risks associated with opioids; patient receipt and comprehension of the medication guide and patient counseling document; patient satisfaction with access to opioids; drug utilization and changes in prescribing patterns; and surveillance of ER/LA opioid misuse, abuse, overdose, addiction, and death. The results of these assessments indicate that the increasing rates of opioid abuse, addiction, overdose, and death observed prior to implementation of the REMS have since leveled off or started to decline. However, these benefits cannot be attributed solely to the ER/LA opioid analgesics REMS since many other initiatives to prevent abuse occurred contemporaneously. These improvements occurred while preserving patient access to opioids as a large majority of patients surveyed expressed satisfaction with their access to opioids.

    Opioid addiction has been a big trouble for human being for several centuries. In China, it also has become a main direct threat against national safety, society advancement, economic development and public health. Based on the national report in 2002, the number of addicts registered in due form is over 1 million, which are distributed in 2148 counties and cities in China. The real number of addicts, however, is much more than those as mentioned above. Money used for buying opioids each year in China might be over 10 billion except for other payment. Base on the statistics, 20 - 50% crimes are commited by addicts. On the other hand, drug abuse often induces contagion spread, such as tuberculosis, hepatitis and HIV disease. About 70% HIV positive subjects in China are related to drug abuse. We are very happy to see more andmore attention has been paid to the problem in our country. Recently, a program on neurobiological basis and medical biological measures of addiction has been supported by National Science and Technology Ministry as a 973 program.

While Turk et al2 have elucidated the complexity of producing high-quality research on the efficacy of ADFs to reduce opioid abuse, recent data are encouraging. For example, since Purdue Pharma’s (Stamford, CT, USA voluntary reformulation of OxyContin® to an ADF in 2010, abuse of the medication has decreased significantly.4–6 As a specific example, National Poison Data System statistics indicated a 36% reduction in abuse exposure for OxyContin following ADF reformulation. Meanwhile, researchers for Purdue Pharma found an increase in abuse exposure for other single-entity oxycodone products and a 42% increase in abuse exposure for heroin during the same time frame.7 Although OxyContin has been the most investigated abuse deterrent formulation, ADFs of other opioids have demonstrated promise in preliminary investigations.8,9

  20. Opioids in Preclinical and Clinical Trials

    Science.gov (United States)

    Nagase, Hiroshi; Fujii, Hideaki

    Since 1952, when Gates determined the stereo structure of morphine, numerous groups have focused on discovering a nonnarcotic opioid drug [1]. Although several natural, semisynthetic, and synthetic opioid ligands (alkaloids and peptides) have been developed in clinical studies, very few were nonnarcotic opioid drugs [2]. One of the most important studies in the opioid field appeared in 1976, when Martin and colleagues [3] established types of opioid receptors (these are now classified into μ, δ, and κ types). Later, Portoghese discovered a highly selective μ type opioid receptor antagonist, β-funaltrexamine [4]. This led to the finding that the μ type opioid receptor was correlated to drug dependence [5]. Consequently, δ, and particularly κ, opioid agonists were expected to lead to ideal opioid drugs. Moreover, opioid antagonists were evaluated for the treatment of symptoms related to undesirable opioid system activation. In this chapter, we provide a short survey of opioid ligands in development and describe the discovery of the two most promising drugs, TRK-851 [6] and TRK-820 (nalfurafine hydrochloride) [7].

    Multiple pharmacotherapies are available for the treatment of fibromyalgia (FM), including opioid analgesics. We postulate that the mechanism of action of traditional opioids predicts their lack of efficacy in FM. Literature searches of the MEDLINE and Cochrane Library databases were conducted using the search term opioid AND fibromyalgia to identify relevant articles, with no date limitations set. Citation lists in returned articles and personal archives of references were also examined for additional relevant items, and articles were selected based on the expert opinions of the authors. We found no evidence from clinical trials that opioids are effective for the treatment of FM. Observational studies have found that patients with FM receiving opioids have poorer outcomes than patients receiving nonopioids, and FM guidelines recommend against the use of opioid analgesics. Despite this, and despite the availability of alternative Food and Drug Administration-approved pharmacotherapies and the efficacy of nonpharmacologic therapies, opioids are commonly used in the treatment of FM. Factors associated with opioid use include female sex; geographic variation; psychological factors; a history of opioid use, misuse, or abuse; and patient or physician preference. The long-term use of opioid analgesics is of particular concern in the United States given the ongoing public health emergency relating to excess prescription opioid consumption. The continued use of opioids to treat FM despite a proven lack of efficacy, lack of support from treatment guidelines, and the availability of approved pharmacotherapy options provides a cautionary tale for their use in other chronic pain conditions.

    Background Tramadol is an atypical analgesic with monoamine and modest mu opioid agonist activity. The purpose of this study was to evaluate: 1) the efficacy of extended-release (ER) tramadol in treating prescription opioid withdrawal and 2) whether cessation of ER tramadol produces opioid withdrawal. Methods Prescription opioid users with current opioid dependence and observed withdrawal participated in this inpatient, two-phase double blind, randomized placebo-controlled trial. In Phase 1 (days 1-7), participants were randomly assigned to matched oral placebo or ER tramadol (200 or 600 mg daily). In Phase 2 (days 8-13), all participants underwent double blind crossover to placebo. Breakthrough withdrawal medications were available for all subjects. Enrollment continued until 12 completers/group was achieved. Results Use of breakthrough withdrawal medication differed significantly (ptramadol 200 mg produced significantly lower peak ratings than placebo on ratings of insomnia, lacrimation, muscular tension, and sneezing. Only tramadol 600 mg produced miosis in Phase 1. In Phase 2, tramadol 600 mg produced higher peak ratings of rhinorrhea, irritable, depressed, heavy/sluggish, and hot/cold flashes than placebo. There were no serious adverse events and no signal of abuse liability for tramadol. Conclusions ER tramadol 200 mg modestly attenuated opioid withdrawal. Mild opioid withdrawal occurred after cessation of treatment with 600 mg tramadol. These data support the continued investigation of tramadol as a treatment for opioid withdrawal. PMID:23755929

    Instituting drug holidays for chronic opioid using patients is becoming commonplace for pain practitioners initiating procedures such as intrathecal pump or spinal cord stimulator trials. As such, pain practitioners need to be adept in their management of acute opioid withdrawal. Successfully weaning an opioid dependent patient off of chronic opioids requires a thorough knowledge of the available adjuvants to assist in this process. However, that selection can become exhausted by adjuvant side effects or by ineffective attenuation of opioid withdrawal symptoms. In that case, novel drugs, or novel application of currently available medications must be sought after to assist in the drug holiday. We present a case in which refractory muscle spasms secondary to opioid withdrawal were successfully treated with an over-the-counter supplement that is not typically used for the attenuation of opioid withdrawal symptoms. In a patient intolerant to the side effects of clonidine, we were able to successfully wean chronic opiates by treating refractory muscle spasms with the serotonin precursor, 5-hydroxytryptophan (5-HTP). We hypothesize that our success with this medication gives further credence to the role of serotonin in opioid withdrawal somatic symptomatology, and supports the need for future research to clarify the role of serotonin precursors or serotonin modulating drugs as potential alternatives in those unable to follow standard treatment protocols.

Opioid analgesic medication is the mainstay of treatment in cancer patients as per the World Health Organization (WHO pain relief ladder, yet 50% of cancer patients worldwide do not receive adequate pain relief or are undertreated. Aim: The aim of this study was to audit the ongoing opioid-prescribing practices in our tertiary cancer pain clinic during January-June 2010. Materials& Methods: The prescribed type of opioid, dose, dosing interval, and laxatives details were analyzed. Results: Five hundred pain files were reviewed and 435 were found complete for audit. Three hundred forty-eight (80% patients were prescribed opioids. Two hundred fifty-nine (74.4% received weak opioids while 118 (33.9% received strong opioids. A total of 195 (45% patients had moderate and 184 (42% had severe pain. Ninety-three (26.7% patients received morphine; however, only 31.5% (58 of 184 in severe pain received morphine as per the WHO pain ladder. Only 73 of 93 (78.4% patients received an adequate dose of morphine with an adequate dosing interval and only 27 (29% were prescribed laxatives with morphine. Conclusion: This study shows that the under treatment of pain and under dosing of opioids coupled with improper side effect management are major issues.

    Full Text Available Michael Soyka1,21Department of Psychiatry and Psychotherapy, Ludwig-Maximilians-Universität, Munich, Germany; 2Private Hospital Meiringen, Meiringen, SwitzerlandAbstract: Opioid maintenance therapy is a well-established first-line treatment approach in opioid dependence. Buprenorphine, a partial opioid agonist, has been found by numerous studies to be an effective and safe medication in the treatment of opioid dependence. At present, buprenorphine is available as a monodrug or in a fixed 4:1 ratio combination with naloxone. A diminished risk of diversion and abuse for the buprenorphine–naloxone combination is likely but not firmly established. Conventional formulations are given sublingually to avoid the hepatic first-pass effect. A novel film tablet is available only in the US and Australia. Other novel, sustained-release formulations (implant, depot are currently being developed and tested. Recent studies, including a Cochrane meta-analysis, suggest that the retention with buprenorphine is lower than for methadone, but that buprenorphine may be associated with less drug use. Higher doses of buprenorphine are associated with better retention rates. Buprenorphine has a ceiling effect at the opioid receptor with regard to respiratory depression, and may cause fewer fatal intoxications than methadone. Possible antidepressant effects of buprenorphine and its use in comorbid psychiatric patients has not been studied in much detail. Clinical implications are discussed.Keywords: buprenorphine, methadone, naloxone, opioids, opioid dependence, therapy

    To develop effective programs for people who are opioid dependent and to impact the opioid epidemic in New York City, it is crucial to monitor attitudes about opioid addiction treatments among opioid users who have experienced barriers to engagement and retention in addiction treatment. The authors conducted a qualitative study using focus groups. Six focus groups in three needle exchanges in New York City were audio recorded, transcribed, and systematically coded. The authors report on the main themes related to the study objectives. Participants of each needle exchange who were opioid dependent and had some knowledge of both methadone and buprenorphine were eligible. There were four main findings. Participants felt the following: 1) buprenorphine is an appropriate option for those heroin users who are motivated to stop using, 2) they have less control over their addiction treatment with methadone than they would have with buprenorphine, 3) buprenorphine treatment is not accessible to many New York City residents who would benefit from this treatment, and 4) lack of access to buprenorphine treatment is a cause of treatment-related diversion. Both methadone maintenance and buprenorphine treatment opportunities are necessary to address the diverse treatment needs of opioid-dependent people in New York City. However, the current medical model of buprenorphine treatment may be too restrictive for some opioid-dependent people and may be contributing to the use of illicit buprenorphine. New models to deliver buprenorphine treatment may address these problems.

    Objective Pain remains insufficiently treated in hospitals. Increasing evidence suggests human factors contribute to this, due to nurses failing to administer opioids. This behavior might be the consequence of nurses’ mental models about opioids. As personal experience and conceptions shape these models, the aim of this prospective survey was to identify model-influencing factors. Material and methods A questionnaire was developed comprising of 14 statements concerning ideations about opioids and seven questions concerning demographics, indicators of adult learning, and strength of religious beliefs. Latent variables that may underlie nurses’ mental models were identified using undirected graphical dependence models. Representative items of latent variables were employed for ordinal regression analysis. Questionnaires were distributed to 1,379 nurses in two London, UK, hospitals (n=580) and one German (n=799) hospital between September 2014 and February 2015. Results A total of 511 (37.1%) questionnaires were returned. Mean (standard deviation) age of participants were 37 (11) years; 83.5% participants were female; 45.2% worked in critical care; and 51.5% had more than 10 years experience. Of the nurses, 84% were not scared of opioids, 87% did not regard opioids as drugs to help patients die, and 72% did not view them as drugs of abuse. More English (41%) than German (28%) nurses were afraid of criminal investigations and were constantly aware of side effects (UK, 94%; Germany, 38%) when using opioids. Four latent variables were identified which likely influence nurses’ mental models: “conscious decision-making”; “medication-related fears”; “practice-based observations”; and “risk assessment”. They were predicted by strength of religious beliefs and indicators of informal learning such as experience but not by indicators of formal learning such as conference attendance. Conclusion Nurses in both countries employ analytical and affective mental

    Opioid peptides and their G-protein-coupled receptors (delta, kappa, mu) are located in the central nervous system and peripheral tissues. The opioid system has been studied to determine the intrinsic mechanism of modulation of pain and to develop uniquely effective pain-control substances with minimal abuse potential and side effects. Two types of endogenous opioid peptides exist, one containing Try-Gly-Gly-Phe as the message domain (enkephalins, endorphins, dynorphins) and the other containing the Tyr-Pro-Phe/Trp sequence (endomorphins-1 and -2). Endomorphin-1 (Tyr-Pro-Trp-Phe-NH2), which has high mu receptor affinity (Ki = 0.36 nM) and remarkable selectivity (4000- and 15,000-fold preference over the delta and kappa receptors, respectively), was isolated from bovine and human brain. In addition, endomorphin-2 (Tyr-Pro-Phe-Phe-NH2), isolated from the same sources, exhibited high mu receptor affinity (Ki = 0.69 nM) and very high selectivity (13,000- and 7500-fold preference relative to delta and kappa receptors, respectively). Both opioids bind to mu-opioid receptors, thereby activating G-proteins, resulting in regulation of gastrointestinal motility, manifestation of antinociception, and effects on the vascular systems and memory. To develop novel analgesics with less addictive properties, evaluation of the structure-activity relationships of the endomorphins led to the design of more potent and stable analgesics. Opioidmimetics and opioid peptides containing the amino acid sequence of the message domain of endomorphins, Tyr-Pro-Phe/Trp, could exhibit unique binding activity and lead to the development of new therapeutic drugs for controlling pain.

    Full Text Available Wojciech Leppert Chair and Department of Palliative Medicine, Poznan University of Medical Sciences, Poznan, Poland Abstract: Opioid-induced bowel dysfunction (OIBD comprises gastrointestinal (GI symptoms, including dry mouth, nausea, vomiting, gastric stasis, bloating, abdominal pain, and opioid-induced constipation, which significantly impair patients’ quality of life and may lead to undertreatment of pain. Traditional laxatives are often prescribed for OIBD symptoms, although they display limited efficacy and exert adverse effects. Other strategies include prokinetics and change of opioids or their administration route. However, these approaches do not address underlying causes of OIBD associated with opioid effects on mostly peripheral opioid receptors located in the GI tract. Targeted management of OIBD comprises purely peripherally acting opioid receptor antagonists and a combination of opioid receptor agonist and antagonist. Methylnaltrexone induces laxation in 50%–60% of patients with advanced diseases and OIBD who do not respond to traditional oral laxatives without inducing opioid withdrawal symptoms with similar response (45%–50% after an oral administration of naloxegol. A combination of prolonged-release oxycodone with prolonged-release naloxone (OXN in one tablet (a ratio of 2:1 provides analgesia with limited negative effect on the bowel function, as oxycodone displays high oral bioavailability and naloxone demonstrates local antagonist effect on opioid receptors in the GI tract and is totally inactivated in the liver. OXN in daily doses of up to 80 mg/40 mg provides equally effective analgesia with improved bowel function compared to oxycodone administered alone in patients with chronic non-malignant and cancer-related pain. OIBD is a common complication of long-term opioid therapy and may lead to quality of life deterioration and undertreatment of pain. Thus, a complex assessment and management that addresses underlying

    Full Text Available Many patients are admitted to the intensive care unit (ICU for acute intoxication, serious complication of overdose, or withdrawal symptoms of illicit drugs. An acute withdrawal of drugs with addiction potential is associated with a sympathetic overactivity leading to marked psychomimetic disturbances. Acute intoxication or withdrawal of such drugs is often associated with life-threatening complications which require ICU admission and necessitate prolonged sedative analgesic medications, weaning from which is often complicated by withdrawal and other psychomimetic symptoms. Dexmedetomidine, an alpha-2 (α2 agonist, has been used successfully to facilitate withdrawal and detoxification of various drugs and also to control delirium in ICU patients. Herein, we report a case of a chronic opioid abuse (heroin patient admitted with acute overdose complications leading to a prolonged ICU course requiring sedative-analgesic medication; the drug withdrawal-related symptoms further complicated the weaning process. Dexmedetomidine infusion was successfully used as a sedative-analgesic to control the withdrawal-related psychomimetic symptoms and to facilitate smooth detoxification and weaning from opioid and other sedatives.

    Prescription Drug Monitoring Programs (PDMP) are statewide databases that collect data on prescription of controlled substances. New York State mandates prescribers to consult the PDMP registry before prescribing a controlled substance such as opioid analgesics. The effect of mandatory PDMP on opioid drug prescriptions by dentists is not known. This study investigates the impact of mandatory PDMP on frequency and quantity of opioid prescriptions by dentists in a dental urgent care center. Based on the sample size estimate, we collected patient records of a 3-month period before and two consecutive 3-month periods after the mandatory PDMP implementation and analyzed the data on number of visits, treatment types and drug prescriptions using Chi-square tests. For patients who were prescribed pain medications, 452 (30.6%), 190 (14.1%), and 140 (9.6%) received opioid analgesics in the three study periods respectively, signifying a statistically significant reduction in the number of opioid prescriptions after implementation of the mandatory PDMP (pPrescriptions for non-opioid analgesics acetaminophen increased during the same periods (pprescription pattern for pain medications by dentists. Such change in prescription pattern represents a shift towards the evidence-based prescription practices for acute postoperative pain.

In the 1980s, the American pain medicine landscape was characterized by opiophobia, the fear to prescribe opioids. Around the turn of the millennium, however, we witnessed a fairly rapid shift to opiophilia, or the "overprescribing" of opioids. The ubiquitous undertreatment of pain was the catalyst for clinicians and pain societies to successfully lobby for increased use of opioids for all pain types, including non-cancer pain. The approval of new standards for pain management incorporating pain as the "fifth vital sign" by the Joint Commission on Accreditation of Healthcare Organizations (JCAHO1 seemingly fueled this increase in opioid prescription. From 1991–2009, prescriptions for opioid analgesics tripled, with emergency department visits related to non-medical use of prescription opioid overdoses doubling from 2005–2009.2 In 2010, accidental overdose deaths associated with opioids increased for the eleventh consecutive year, highlighting the drastic shift in opioid use.3 The figurative pendulum began to swing toward opiophobia following the publication of data that demonstrated that the risk of addiction associated with chronic opioid use was likely underestimated.4 Guidelines for the use of controlled substances released by the Federation of State Medical Boards of the US in 1998 reflected this change in attitude.5 At present, there is a general consensus that opioids are over-prescribed and education among health

    Opioids are among the oldest known and most widely used analgesics. The application of opioids has expanded over the last few decades, especially in the treatment of chronic non-malignant pain. This upsurge in opioid use has been accompanied by the increasingly recognized occurrence of opioid-associated endocrinopathy. This may arise after exposure to enteral, parenteral, or neuraxial opioids. Opioid-associated endocrinopathy consists primarily of hypothalamic-pituitary-gonadal axis or hypothalamic-pituitary-adrenal axis dysfunction and may manifest with symptoms of hypogonadism, adrenal dysfunction, and other hormonal disturbances. Additionally, opioid related endocrine dysfunction may be coupled with such disorders as osteoporosis and mood disturbances including depression. Undesirable changes in pain sensitivity such as opioid-induced hyperalgesia, and reduced potency of opioid analgesia may also be potential consequences of chronic opioid consumption. Few studies to date have been able to establish what degree of opioid exposure, in terms of dose or duration of therapy, may predispose patients to opioid-associated endocrinopathy. This article will review the currently available literature concerning opioid-associated endocrinopathy and will provide recommendations for the evaluation, monitoring, and management of opioid-associated endocrinopathy and its other accompanying undesired effects.

  18. Management of opioid-induced constipation.

    Prichard, David; Norton, Christine; Bharucha, Adil E

    Up to 40% of patients taking opioids develop constipation. Opioid-induced constipation (OIC) may limit the adequate dosing of opioids for pain relief and reduce quality of life. Health professionals must therefore inquire about bowel function in patients receiving opioids. The management of OIC includes carefully re-evaluating the necessity, type and dose of opioids at each visit. Lifestyle modification and alteration of aggravating factors, the use of simple laxatives and, when essential, the addition of newer laxatives or opioid antagonists (naloxone, naloxegol or methylnaltrexone) can be used to treat OIC. This review discusses the recent literature regarding the management of OIC and provides a rational approach to assessing and managing constipation in individuals receiving opioids.

    Chronic pain patients receiving opioid drugs are at risk for opioid-induced hyperalgesia (OIH), wherein opioid pain medication leads to a paradoxical pain state. OIH involves central sensitization of primary and secondary afferent neurons in the dorsal horn and dorsal root ganglion, similar to neuropathic pain. Gabapentin, a gamma-aminobutyric acid (GABA) analog anticonvulsant used to treat neuropathic pain, has been shown in animal models to reduce fentanyl hyperalgesia without compromising analgesic effect. Chronic pain patients have also exhibited lower opioid consumption and improved pain response when given gabapentin. However, few human studies investigating gabapentin use in OIH have been performed in recent years. In this review, we discuss the potential mechanisms that underlie OIH and provide a critical overview of interventional therapeutic strategies, especially the clinically-successful drug gabapentin, which may reduce OIH.

    Route of administration is an important contributor to the adverse health consequences of prescription medication abuse. The current study examines characteristics associated with non-oral routes of administration among a large sample of prescription opioid abusers and explores needle-related human immunodeficiency virus (HIV) risk behaviors as well. In the study, 791 opioid abusers completed a one-time structured interview, including complete histories of illicit and prescription drug abuse and route of drug administration. The most common method of pill use was oral (91%), followed by intranasal (53.1%), injection (23.8%), and smoking (14.5%). The youngest prescription opioid abusers, ages 18-24, displayed significantly higher odds of using alternate routes of administration and of reusing nonsterile needles for injection. HIV prevention programming should be developed for young prescription opioid injectors.

    Post-traumatic stress disorder is highly prevalent among individuals who suffer from opioid use disorder. Compared to individuals with opioid use disorder alone, those with post-traumatic stress disorder have a worse course of illness, occupational functioning, and physical health. The neurobiological pathways underlying each disorder overlap substantially, and there are multiple pathways through which these disorders may interact. This narrative review explores evidence underpinning 3 explanatory perspectives on comorbid post-traumatic stress disorder and opioid use disorder: The opioid susceptibility model (a.k.a.: the Self-Medication Hypothesis), the post-traumatic stress disorder susceptibility model, and the common factors model. Diagnostic implications, treatment implications, and directions for future research are discussed.

    Pre-clinical and clinical evidence indicates that opioid drugs have stress-dampening effects. In animal models, opioid analgesics attenuate responses to isolation distress, and in humans, opioids reduce stress related to anticipation of physical pain. The stress-reducing effects of opioid drugs may contribute to their abuse potential. Despite this evidence in laboratory animals, the effects of opioids on responses to psychosocial stress have not been determined in humans. Here we examined the effects of buprenorphine, a μ-opioid partial agonist used to treat opioid dependence and pain, on subjective and physiological responses to a stressful public speaking task in healthy adults. We hypothesized that buprenorphine would reduce subjective and physiological stress responses. Healthy adult volunteers (N=48) were randomly assigned to receive placebo, 0.2mg sublingual buprenorphine, or 0.4mg sublingual buprenorphine in a two-session study with a stressful speaking task (Trier Social Stress Test; TSST) and a non-stressful control task. During the sessions, the participants reported on their mood states, provided subjective appraisals of the task, and measures of salivary cortisol, heart rate, and blood pressure at regular intervals. Stress produced its expected effects, increasing heart rate, blood pressure, salivary cortisol, and subjective ratings of anxiety and negative mood. In line with our hypothesis, both doses of buprenorphine significantly dampened salivary cortisol responses to stress. On self-report ratings, buprenorphine reduced how threatening participants found the tasks. These results suggest that enhanced opioid signaling dampens responses to social stress in humans, as it does in laboratory animals. This stress-dampening effect of buprenorphine may contribute to the non-medical use of opioid drugs.

The aim of the study was to examine the trends in opioid and nonopioid analgesic consumption in Croatia between 2007 and 2013. Methods: Data on opioid consumption were extracted from the database of the national authority. All opioid and nonopioid analgesics were included in the analysis. Data were presented as defined daily doses per 1,000 inhabitants per day. Adequacy of opioid consumption was calculated using adequacy of consumption measure. Results: During the examined 7-year period, the total consumption and total cost of all analgesics in Croatia showed continuous increase. In the M01A group (anti-inflammatory and antirheumatic products, nonsteroids, ibuprofen had an exponential increasing trend, and in 2011, it overtook diclofenac consumption. Ibuprofen and diclofenac had the highest consumption also in the M02A group of topical products for joint and muscular pain. Tramadol was by far the most consumed type of opioids (N02A group and paracetamol in the group of other analgesics and antipyretics (N02B. The adequacy of consumption measure value was 0.19, indicating that Croatia is a country with a low opioid consumption. Conclusion: Between 2007 and 2013, both consumption of analgesics and their cost in Croatia had an increasing trend. Comparisons with data from other countries, based on the published literature, indicate that analgesic consumption in Croatia is still relatively low. Calculation of the adequacy of opioid consumption indicated that Croatia is a country with low opioid consumption. Further studies are necessary for establishing whether current analgesic consumption in

    Abstract Background Opioid agonist drugs produce analgesia. However, long-term exposure to opioid agonists may lead to opioid dependence. The analgesic and addictive properties of opioid agonist drugs are mediated primarily via the mu-opioid receptor (MOR). Opioid agonists appear to alter neuronal morphology in key brain regions implicated in the development of opioid dependence. However, the precise role of the MOR in the development of these neuronal alterations remains elusive. We hypothes...

    Pain relief is vital to the treatment of cancer. Despite the widespread use and recognition of clinical recommendations for the management of cancer-related pain, avoidable suffering is still prevalent in patients with malignant disease. A gap exists between what is known about pain medical management and actual practices of patients, caregivers, healthcare professionals and institutions. Opioids are the pillar of the medical management of moderate to severe pain. The prescription of opioid analgesics - by a registered medical practitioner for absolute pain control - is a legitimate practice. In this article we look at patients' fears and physicians' general hesitations towards morphine and alike. We examine misconceptions that yield fallacies on the therapeutically use of opioids and, therefore, sustain inadequate pain management.

    The long-term treatment of patients with chronic temporomandibular joint dysfunction has been challenging. The long-term use of opioids in these patients can be neither supported nor refuted based on current evidence. However, evidence is available to support the long-term use of opioids in other chronic noncancer pain states with reduced pain, improved function, and improved quality of life. One group of patients with chronic temporomandibular joint pain, for whom both noninvasive and invasive treatment has failed, might benefit from long-term opioid medication. The choices include morphine, fentanyl, oxycodone, tramadol, hydrocodone, and methadone. Adjunct medication, including antidepressant and anticonvulsant drugs, can also be used. The safety of these medications has been well established, but the potential for adverse drug-related behavior does exist, requiring appropriate patient selection, adequate monitoring, and intervention when needed.

    Climate science as a whole as well as reanalyses as a special case can significantly profit from the recovery, imaging and digitisation of historical observations. The importance of this fact is reflected in large, global data rescue projects and initiatives such as the Atmospheric Circulation Reconstructions over the Earth (ACRE, www.met-acre.org) or the EU FP7 ERA-CLIM project (www.era-clim.eu). From the time before 1957, there are still large amounts of surface data e.g. from former colonies and from overseas territories of European countries )e.g. Portugal, France and Germany) that need to be rescued. Also in case of the very early upper-air observations before the 1930s, even Europe and North America still hold an important quantity of data to be recovered in digital form. Here, we present the web platform "Data Rescue @ Home" (www.data-rescue-at-home.org), which has been developed at ETH Zurich and Oeschger Centre for Climate Change Research, and which has been designed to take advantage of the voluntary assistance of the thousands of people on the web who are interested in climate or old weather data. On the website, these volunteers can enter meteorological data shown on digital images into entry masks that resemble the original. By registering, the users get access to their personal digitisation statistics and help optimising the project. At the moment, 4 digitisation projects are online: One project is dealing with German upper-air data from the Second World War period. In a second project, station data from Tulagi (Solomon Islands) is being digitised. Finally, two collaborative projects have been included: One in cooperation with the Instituto Dom Luiz (Univ. Lisbon, Portugal), where Portuguese station data from Angra (Azores) is digitised, and a further one in cooperation with the German Meteorological Service (DWD), in which precipitation data from former German colonies is being digitised. On our poster, we will report on the status of the projects

A specific medical rescue mobile team was established, made up of medical officers, nurses, and drivers. The medical personnel came from the departments of burn, orthopedics, general surgery, respiratory diseases, neurology, etc.,all with the middle or higher professional titles. All of them had gone into the disaster relief in the earthquake-stricken area of Wenchuan, Sichuan Province,participated in the Olympic security and crisis control,and several military exercises organized by the military area command and had excellent military quality, health service insurance ability, and professional skills. In addition, they received training of theories on individual nuclear radiation, chemical events, and biological terrorist attack, and basic skills of individual protection and first aid, rapid response, and co-training, so that they became experts in one thing and versatile at many. An emergency plan had been developed in advance. In the light of the realistic situation of traffic in Shanghai, several flexible driving routes were planned so as to determine the best way to reach the emergency spot. During the waiting periods the personnel remained in the hospital and would set off in 18 min after receiving the order.During the period of standby for the World Expo lasting 8 months, the medical rescue emergency mobile group not only did its work to perfection, but also stored up necessary personnel and skills for the potential nuclear,chemical, and biological emergency events that should occur in the future, peacetime or wartime.%2010年,中国人民解放军第八五医院参与了上海世博会的"三防"医学救援工作,组成"三防"医学救援应急机动组,成员包括军医、护士和司机.医务人员来自烧伤外科、骨科、普外科、呼吸科、神经内科

    Pain catastrophizing is a maladaptive response to pain that amplifies chronic pain intensity and distress. Few studies have examined how pain catastrophizing relates to opioid prescription in outpatients with chronic pain. The authors conducted a retrospective observational study of the relationships between opioid prescription, pain intensity, and pain catastrophizing in 1,794 adults (1,129 women; 63%) presenting for new evaluation at a large tertiary care pain treatment center. Data were sourced primarily from an open-source, learning health system and pain registry and secondarily from manual review of electronic medical records. A binary opioid prescription variable (yes/no) constituted the dependent variable; independent variables were age, sex, pain intensity, pain catastrophizing, depression, and anxiety. Most patients were prescribed at least one opioid medication (57%; n = 1,020). A significant interaction and main effects of pain intensity and pain catastrophizing on opioid prescription were noted (P < 0.04). Additive modeling revealed sex differences in the relationship between pain catastrophizing, pain intensity, and opioid prescription, such that opioid prescription became more common at lower levels of pain catastrophizing for women than for men. Results supported the conclusion that pain catastrophizing and sex moderate the relationship between pain intensity and opioid prescription. Although men and women patients had similar Pain Catastrophizing Scale scores, historically "subthreshold" levels of pain catastrophizing were significantly associated with opioid prescription only for women patients. These findings suggest that pain intensity and catastrophizing contribute to different patterns of opioid prescription for men and women patients, highlighting a potential need for examination and intervention in future studies.

    Persistent opioid use following surgery has received increasing attention from policymakers, researchers, and clinicians. Perioperative nerve blockade has been hypothesized to decrease the risk of persistent opioid use. We examined whether nerve blockade was associated with a decreased risk of persistent opioid use among patients undergoing shoulder arthroplasty, a procedure with high rates of persistent postoperative pain. Using health care claims data, we constructed a sample of 6695 patients undergoing shoulder arthroplasty between 2002 and 2012 and used billing data to identify the utilization of nerve blockade. We then used a multivariable logistic regression to estimate the association between nerve blockade and 2 measures of opioid use: having filled at least 1 prescription for an opioid between postoperative days (PODs) 0 and 90, and between POD 91 and 365. This regression adjusted for a variety of potential confounders, such as preoperative opioid use and medical history. There was no association between nerve blockade and our 2 measures of persistent opioid use: adjusted odds ratio, 1.12 (97.5% confidence interval, 0.939-1.34; P = .15) for opioid use between POD 0 and 90, and adjusted odds ratio, 0.997 (97.5% confidence interval, 0.875-1.14; P = .95) for opioid use between POD 91 and 365. Although the use of perioperative nerve blockade may offer short-term benefits, in this study, it was not associated with a reduction in the risk of persistent opioid use for patients undergoing shoulder arthroplasty.

    Research grounded in behavioral economics has previously linked addictive behavior to disrupted decision-making and reward-processing, but these principles have not been examined in prescription opioid addiction, which is currently a major public health problem. This study examined whether pre-treatment drug reinforcement value predicted opioid use during outpatient treatment of prescription opioid addiction. Secondary analyses examined participants with prescription opioid dependence who received 12 weeks of buprenorphine-naloxone and counseling in a multi-site clinical trial (N=353). Baseline measures assessed opioid source and indices of drug reinforcement value, including the total amount and proportion of income spent on drugs. Weekly urine drug screens measured opioid use. Obtaining opioids from doctors was associated with lower pre-treatment drug spending, while obtaining opioids from dealers/patients was associated with greater spending. Controlling for demographics, opioid use history, and opioid source frequency, patients who spent a greater total amount (OR=1.30, peconomic resources to drugs, reflects propensity for continued opioid use during treatment among individuals with prescription opioid addiction. Future studies should examine disrupted decision-making and reward-processing in prescription opioid users more directly and test whether reinforcer pathology can be remediated in this population.

    Background The purpose of this study was to gain an understanding of the profiles of the new treatment demands posed by opioid addicts between 2005 and 2010 at the addictive disorders assistance units in Galicia, Spain. Methods A cluster analysis was performed using data from 1,655 treatment entrants. Clusters were constructed using sociodemographic and medicolegal variables. A cluster analysis was also conducted according to age. Once clusters were defined, their association with the following variables was analyzed: age at first use of opioids, years of use, frequency of opioid use in the previous month, psychiatric treatment, cocaine use, existence of a drug-dependent partner, and source of referral. Results Four clusters were obtained in the main analysis. Cluster 1 (34.01%) consisted of young males, cluster 2 (16.19%) consisted of not-so-young males, cluster 3 (32.62%) consisted mainly of older males and a small group of females, and cluster 4 (17.18%) was made up entirely of women. With regard to age-related clusters, two clusters were obtained in those under the age of 30 years: cluster 1 (73%) without medicolegal complications and cluster 2 (27%) with medicolegal complications. For those over the age of 30 years, two clusters were obtained: cluster 1 (53.92%) with hardly any medicolegal complications and cluster 2 (46.08%) with medicolegal complications. Conclusion Cluster analysis suggests that there have been no substantial changes in variables indicating greater severity in this new group of patients. Women are likely to seek help earlier, which reduces their duration of opioid use. The younger the patient, the shorter the duration of opioid use and the greater the likelihood of cessation of intravenous use. Public health systems should use a two-pronged treatment strategy of short but intense cessation therapies for women and younger treatment entrants and longer maintenance and replacement therapies for older treatment entrants with more psychosocial

  19. Novel approaches for the treatment of psychostimulant and opioid abuse – focus on opioid receptor-based therapies

    Introduction Psychostimulant and opioid addiction are poorly treated. The majority of abstinent users relapse back to drug-taking within a year of abstinence, making ‘anti-relapse’ therapies the focus of much current research. There are two fundamental challenges to developing novel treatments for drug addiction. Firstly, there are 3 key stimuli that precipitate relapse back to drug-taking: stress, presentation of drug-conditioned cue, taking a small dose of drug. The most successful novel treatment would be effective against all 3 stimuli. Secondly, a large number of drug users are poly-drug users: taking more than one drug of abuse at a time. The ideal anti-addiction treatment would therefore be effective against all classes of drugs of abuse. Areas Covered In this review, the authors discuss the clinical need and animal models used to uncover potential novel treatments. There is a very broad range of potential treatment approaches and targets currently being examined as potential anti-relapse therapies. These broadly fit into 2 categories: ‘memory-based’ and ‘receptor-based’ and the authors discuss the key targets here within. Expert opinion Opioid receptors and ligands have been widely studied, and research into how different opioid subtypes affect behaviours related to addiction (reward, dysphoria, motivation) suggests that they are tractable targets as anti-relapse treatments. Regarding opioid ligands as novel ‘anti-relapse’ medications targets - research suggests that a ‘non-selective’ approach to targeting opioid receptors will be the most effective. PMID:25253272

    2007-01-01

    The notion of location awareness in a Mountain Rescue domain is critical for the mission coordinator of a Mountain Rescue Team who tries to organize the team and make informed decisions for all its members. The knowledge of location of each member of the team while they are on a mission, could be provided by sending GPS coordinates from a device that each rescue worker would carry, to the server of the team located at its headquarters. The physical characteristics of the Mountain Rescue domai...

    Background This study's objectives were to evaluate whether WCB claimants with conditions requiring certain surgical procedures are more likely to be prescribed outpatient opioids than other Manitobans and whether those prescribed opioids are more likely to still be on opioid medications 6 months post procedure. Methods We compared 7,246 WCB claims for a number of surgical procedures to 65,032 similar procedures performed in other Manitobans. Logistic regression was used to explore the association between being a WCB claimant and being prescribed opioids, while controlling for type of surgical procedure and other potential confounders. Results WCB claimants were more likely than other Manitobans to be prescribed opioids (adjusted OR 1.38; 95%CI 1.30–1.47). Amongst those prescribed opioids, the odds of being still on opioids 6 months post‐procedure were not significantly elevated for WCB claimants (adjusted OR 1.09 95%CI 0.97–1.23). Conclusions WCB claimants are prescribed opioids more often than non‐claimants for similar procedures. Am. J. Ind. Med. 59:257–263, 2016. © 2016 The Authors.

    Predominant among the production constraints of the common bean Phaseolus vulgaris are infestation of Ascochyta blight, Bean Golden Mosaic virus (BGMV), and Bean Fly. Interbreeding with Phaseolus -coccineus L. and/or Phaseolus polyanthus Greenm has been shown to provide P. vulgaris with greater resistance to these diseases. For interspecific crosses to be successful, it is important to use P. coccineus and P. polyanthus as female parents; this prevents rapid reversal to the recurrent parent P. vulgaris. Although incompatibility barriers are post-zygotic, early hybrid embryo abortion limits the success of F1 crosses. While rescue techniques for globular and early heart-shaped embryos have improved in recent years, -success in hybridization remains very low. In this study, we describe six steps that allowed us to rescue 2-day-old P. vulgaris embryos using a pod culture technique. Our methods consisted of (i) pod culture, (ii) extraction and culture of immature embryos, (iii) dehydration of embryos, (iv) germination of embryos, (v) rooting of developed shoots, and (vi) hardening of plantlets.

    Increase in the number of opioid-dependent pregnant women delivering babies at risk for neonatal abstinence syndrome prompted a US Government Accountability Office report documenting deficits in research and provider knowledge about care of the maternal/fetal unit and the neonate. There are 3 general sources of dependence: untreated opioid use disorder, pain management, and medication-assisted treatment with methadone or buprenorphine. A survey of methadone patients' experiences when telling a physician of their pregnancy and opioid dependence demonstrated physician confusion about proper care, frequent negative interactions with the mother, and failures to provide appropriate referral. Patients in pain management were discharged without referral when the physician was told of the pregnancy. Methadone and buprenorphine were frequently seen negatively because they "caused" neonatal abstinence syndrome. Most mothers surveyed had to find opioid treatment on their own. How dependence is managed medically is a critical determinant of the level of stress on both mother and fetus, and therefore another determinant of neonatal health. The effects of both opioid withdrawal stress and maternal emotional stress on neonatal and developmental outcomes are reviewed. Currently, there have been efforts to criminalize maternal opioid dependence and to encourage or coerce pregnant women to undergo withdrawal. This practice poses both acute risks of fetal hypoxia and long-term risks of adverse epigenetic programming related to catecholamine and corticosteroid surges during withdrawal. Contemporary studies of the effects of withdrawal stress on the developing fetal brain are urgently needed to elucidate and quantify the risks of such practices. At birth, inconsistencies in the hospital management of neonates at risk for neonatal abstinence syndrome have been observed. Neglect of the critical role of maternal comforting in neonatal abstinence syndrome management is an iatrogenic and

    In Australia, deaths due to the ingestion of opioid analgesics, though numerically small, have been increasing at a rapid rate. The reasons for this increase are multifactorial; the conceptually outdated legislation that controls prescription and administration of opioid analgesics might be one of them. The stated purposes of the governing statutory instruments include prevention of the improper use of drugs of dependence and protection of the public. However, in order to achieve these aims, the relevant legislation should utilise theories and definitions that are consistent with the medical understanding of the relevant physiology and behaviour, so as to provide a common linguistic and conceptual platform for regulatory and clinical decision-makers. Although Victoria, with its intricate statutory framework for Schedule 8 poisons, is used as an example of an obsolescent approach to the concept of drug dependency, conclusions reached are applicable to other jurisdictions, other scheduled drugs, and all health care practitioners who have the statutory authority to possess and prescribe them.

    Opiates and related molecules are medically essential, but their production via field cultivation of opium poppy Papaver somniferum leads to supply inefficiencies and insecurity. As an alternative production strategy, we developed baker's yeast Saccharomyces cerevisiae as a microbial host for the transformation of opiates. Yeast strains engineered to express heterologous genes from P. somniferum and bacterium Pseudomonas putida M10 convert thebaine to codeine, morphine, hydromorphone, hydrocodone and oxycodone. We discovered a new biosynthetic branch to neopine and neomorphine, which diverted pathway flux from morphine and other target products. We optimized strain titer and specificity by titrating gene copy number, enhancing cosubstrate supply, applying a spatial engineering strategy and performing high-density fermentation, which resulted in total opioid titers up to 131 mg/l. This work is an important step toward total biosynthesis of valuable benzylisoquinoline alkaloid drug molecules and demonstrates the potential for developing a sustainable and secure yeast biomanufacturing platform for opioids.

    Full Text Available Substance-related and addictive disorders are chronic relapsing conditions that substantially impact public health. Effective treatments for these disorders require addressing substance use/dependence comprehensively as well as other associated comorbidities. Comprehensive addressing of substance use in a medical setting involves screening for substance use, addressing substance use directly with the patient, and formulating an appropriate intervention. For alcohol dependence and opioid dependence, pharmacotherapies are available that are safe and effective when utilized in a comprehensive treatment paradigm, such as medication assisted treatment. In primary care, substance use disorders involving alcohol, illicit opioids, and prescription opioid abuse are common among patients who seek primary care services. Primary care providers report low levels of preparedness and confidence in identifying substance-related and addictive disorders and providing appropriate care and treatment. However, new models of service delivery in primary care for individuals with substance-related and addictive disorders are being developed to promote screening, care and treatment, and relapse prevention. The education and training of primary care providers utilizing approved medications for the treatment of alcohol use disorders and opioid dependence in a primary care setting would have important public health impact and reduce the burden of alcohol abuse and opioid dependence.

    Full Text Available Abstract Background The use of opioid medications as treatment for chronic non-cancer pain remains controversial. Little information is currently available regarding healthcare providers' attitudes and beliefs about this practice among older adults. This study aimed to describe primary care providers' experiences and attitudes towards, as well as perceived barriers and facilitators to prescribing opioids as a treatment for chronic pain among older adults. Methods Six focus groups were conducted with a total of 23 physicians and three nurse practitioners from two academically affiliated primary care practices and three community health centers located in New York City. Focus groups were audiotape recorded and transcribed. The data were analyzed using directed content analysis; NVivo software was used to assist in the quantification of identified themes. Results Most participants (96% employed opioids as therapy for some of their older patients with chronic pain, although not as first-line therapy. Providers cited multiple barriers, including fear of causing harm, the subjectivity of pain, lack of education, problems converting between opioids, and stigma. New barriers included patient/family member reluctance to try an opioid and concerns about opioid abuse by family members/caregivers. Studies confirming treatment benefit, validated tools for assessing risk and/or dosing for comorbidities, improved conversion methods, patient education, and peer support could facilitate opioid prescribing. Participants voiced greater comfort using opioids in the setting of delivering palliative or hospice care versus care of patients with chronic pain, and expressed substantial frustration managing chronic pain. Conclusions Providers perceive multiple barriers to prescribing opioids to older adults with chronic pain, and use these medications cautiously.

    I read with great interest the recent article by Chen et a/in a recent issue of your esteemed journal.The article is highly thought provoking.One emerging therapeutic alternative for opioid induced constipation is the emergence of opioid/naloxone prolonged release combinations.For instance,naloxone when administered in a 1∶2 ratio with oxycodone reverses the inhibitory effect of oxycodone on the gastrointestinal tract.The advantage of oxycodone/naloxone prolonged release (OXN) is that while its anti-nociceptive efficacy is equivalent to that of oxycodone prolonged release (OXC),it significantly decreases the "Bowel Function Index" thereby ameliorating symptoms of opioid induced constipation to a large extent.Schutter et al in a recent study have reported a decrease in the bowel function index from 38.2 to 15.1.Similarly,L(o)wenstein et al in another recent study have reported that following a month of therapy,complete spontaneous bowel movements per week is increased from one in OXC therapy to three in OXN therapy.

    The use of combinations of potent opioids is a common clinical practice. The addition of one potent opioid to another has been recommended to reduce opioid side effects, improve pain control, and limit dose escalation of the first opioid. The advantages of using combined opioids have been reported to be relative to differences in receptor activation versus endocytosis (RAVE). However, the advantages and detriment to combining opioids are related to naturally occurring opioid receptor dimers. Dimers and oligomers result in a unique opioid pharmacodynamics which influence opioid binding, G protein interactions, desensitization, receptor trafficking, and endocytosis. The pharmacodynamics of dimers may lead to positive or negative cooperativity when two opioids are combined. The use of multiple opioids in practice can lead to increased risk for dosing errors, reduced patient compliance, increased drug interactions and cost. Opioid combinations should not be used until prospective randomized trials clarify the benefits and safety.

    Use of chronic opioid therapy has increased substantially over the past few years, even though opioid therapy is associated with potentially serious harms, including opioid-related adverse effects and outcomes. Prescription of opioids for chronic pain, particularly nonmalignant chronic pain, remains controversial. In the midst of this controversy, patterns of actual prescription and influences on these patterns are not well understood. This study aims to describe the frequency of prescription of opioid analgesics in a university hospital, the attitudes of doctors towards this category of drugs, and the follow-up modalities of patients taking these drugs. The study also explores the association between the practitioners' characteristics and the modalities of prescription. A survey was delivered to 112 doctors and surgeons in the hospital during the four months between August and December 2013 and it was returned by 55 (49.0%). The survey consists of three parts. The first part addresses the frequency and reluctance of doctors' prescription of opioids and other analgesics for acute and chronic pain. The second part studies the doctors' attitudes and concerns towards opioids. It explores the belief of the doctors in the efficacy of this category of drugs, their confidence in prescribing such medications and the eventual side effects they might worry about. The third part of the survey studies the modalities of evaluation prior to the prescription and the modalities of follow-up of the patients receiving a long-term opioid treatment. Overall, 76.4% of doctors reported they sometimes, frequently, or always, prescribe opioids, which, using the Wilcoxon test, proved to be a significantly lower frequency than for prescribing of minor analgesics or nonsteroidal anti-inflammatory drugs (NSAIDS). Similarly, 60.1% reported a reluctance to prescribe opioids for chronic nonmalignant pain, which was a significantly greater reluctance than for cancer pain. The age and sex of the

    Ethanol, like other drugs of abuse, has motivating properties that can be developed as animal models of self-administration. A major strength of the operant approach where an animal must work to obtain ethanol is that it reduces confounds due to palatability and controls for nonspecific malaise-inducing effects. In the domain of opioid peptide systems, limited access paradigms have good predictive validity. In addition, animal models of excessive drinking-either environmentally or genetically induced-also appear sensitive to blockade or inactivation of opioid peptide receptors. Ethanol availability can be predicted by cues associated with positive reinforcement, and these models are sensitive to the administration of opioid antagonists. Perhaps most exciting are the recent results suggesting that the key element in opioid peptide systems that is important for the positive reinforcing effects of ethanol is the mu-opioid receptor. How exactly ethanol modulates mu-receptor function will be a major challenge of future research. Nevertheless, the apparently critical role of the mu receptor in ethanol reinforcement refocuses the neuropharmacology of ethanol reinforcement in the opioid peptide domain and opens a novel avenue for exploring medications for treating alcoholism.

    Naltrexone is an opioid receptor antagonist that blocks the reinforcing effects of opioids and reduces alcohol consumption and craving. It has no abuse potential, mild and transient side effects, and thus appears an ideal pharmacotherapy for opioid dependence. Its effectiveness in alcohol dependence is less evident, but compliance with naltrexone combined with psychosocial support has been repeatedly shown to improve drinking outcomes. Limited compliance with oral naltrexone treatment is a known drawback. Several naltrexone implant and injectable depot formulations are being investigated and provide naltrexone release for at least 1 month. Studies among opioid-dependent patients indicate significant reductions in heroin use, but sample sizes are usually small. In alcohol dependence, two large multicenter trials report alcohol and craving reductions for naltrexone and placebo groups, indicating a significant but moderate effect. The pharmacokinetic profile of the injectable formulation indicates reliable naltrexone release over 1 month at therapeutic levels. Implant formulations releasing naltrexone up to 7 months are reported. Findings on safety and tolerability confirm the generally mild adverse effects described for naltrexone tablets. However, further research on therapeutic levels (i.e., opioid blocking) is warranted. The majority of naltrexone implants lacks approval for regular clinical use and larger longitudinal studies are needed. The available naltrexone depot formulations have the potential to significantly improve medication compliance in opioid and alcohol dependence. In certain circumstances, they may constitute a promising new treatment option. © 2010 Blackwell Publishing Ltd.

    The rewarding properties of some abused drugs are thought to reside in their ability to increase striatal dopamine levels. Similar increases have been shown in response to expectation of a positive drug effect. The actions of opioid drugs on striatal dopamine release are less well characterized. We examined whether heroin and the expectation of heroin reward increases striatal dopamine levels in human opioid addiction. Ten opioid-dependent participants maintained on either methadone or buprenorphine underwent [(11) C]raclopride positron emission tomography imaging. Opioid-dependent participants were scanned three times, receiving reward from 50-mg intravenous heroin (diamorphine; pharmaceutical heroin) during the first scan to generate expectation of the same reward at the second scan, during which they only received 0.1-mg intravenous heroin. There was no heroin injection during the third scan. Intravenous 50-mg heroin during the first scan induced pronounced effects leading to high levels of expectation at the second scan. There was no detectable increase in striatal dopamine levels to either heroin reward or expectation of reward. We believe this is the first human study to examine whether expectation of heroin reward increases striatal dopamine levels in opioid addiction. The absence of detectable increased dopamine levels to both the expectation and delivery of a heroin-related reward may have been due to the impact of substitute medication. It does however contrast with the changes seen in abstinent stimulant users, suggesting that striatal dopamine release alone may not play such a pivotal role in opioid-maintained individuals.

    2004-01-01

    A survey of the medical directors of multidisciplinary pain clinics and multidisciplinary pain centers listed in the American Pain Society Pain Facilities Directory was conducted to define those pain specialists' beliefs about the role of opioid analgesia in 14 types of chronic nonmalignant pain. Respondents also reported their perceptions of barriers to their prescribing opioids for chronic nonmalignant pain and what they perceived as barriers to opioid prescribing for chronic nonmalignant pain by other, non-pain specialist clinicians in their communities. The respondents are characterized by demographics, disciplines, specialties, and time in practice. The percentage of time that a pharmacist was available in the pain programs also is reported. There is increasing acceptance of opioids for most of the listed types of chronic nonmalignant pain, but the acceptance varies by types of pain syndromes. Opioids were most consistently accepted for sickle cell disease pain and least commonly endorsed for headaches, myofascial pain, and fibromyalgia. Factors that may influence clinicians' perceptions about opioids are discussed.

    2016-01-01

    Challenges with opioids (e.g., adverse events, misuse and abuse with long-term administration) have led to a renewed emphasis on opioid-sparing multimodal management of trauma pain. To assess the extent to which currently available evidence supports the efficacy and safety of various nonopioid analgesics and techniques to manage trauma pain, a literature search of recently published references was performed. Additional citations were included on the basis of authors' knowledge of the literature. Effective options for opioid-sparing analgesics include oral and intravenous (IV) acetaminophen; nonsteroidal anti-inflammatory drugs available via multiple routes; and anticonvulsants, which are especially effective for neuropathic pain associated with trauma. Intravenous routes (e.g., IV acetaminophen, IV ketorolac) may be associated with a faster onset of action than oral routes. Additional adjuvants for the treatment of trauma pain are muscle relaxants and alpha-2 adrenergic agonists. Ketamine and regional techniques play an important role in multimodal therapy but require medical and nursing support. Nonpharmacologic treatments (e.g., cryotherapy, distraction techniques, breathing and relaxation, acupuncture) supplement pharmacologic analgesics and can be safe and easy to implement. In conclusion, opioid-sparing multimodal analgesia addresses concerns associated with high doses of opioids, and many pharmacologic and nonpharmacologic options are available to implement this strategy. Nurses play key roles in comprehensive patient assessment; administration of patient-focused, opioid-sparing, multimodal analgesia in trauma; and monitoring for safety concerns. PMID:27828892

  5. Benzodiazepines: a major component in unintentional prescription drug overdoses with opioid analgesics.

    2014-02-01

    The misuse and abuse of prescription medications in the United States continues to increase despite interventions by health care professionals, regulatory, and law enforcement agencies. Opioid analgesics are the leading class of prescription drugs that have caused unintentional overdose deaths. Benzodiazepines when taken alone are relatively safe agents in overdose. However, a 5-fold increase in deaths attributed to benzodiazepines occurred from 1999 to 2009. Emergency department visits related to opioid analgesics increased by 111% followed by benzodiazepines 89%. During 2003 to 2009, the 2 prescriptions drugs with the highest increase in death rates were oxycodone 264.6% and alprazolam 233.8%. Therefore, benzodiazepines have a significant impact on prescription drug unintentional overdoses second only to the opioid analgesics. The combination prescribing of benzodiazepines and opioid analgesics commonly takes place. The pharmacokinetic drug interactions between benzodiazepines and opioid analgesics are complex. The pharmacodynamic actions of these agents differ as their combined effects produce significant respiratory depression. Physician and pharmacy shopping by patients occurs, and prescription drug-monitoring programs can provide important information on benzodiazepine and opioid analgesic prescribing patterns and patient usage. Health care professionals need to inform patients and work closely with regulatory agencies and legislatures to stem the increasing fatalities from prescription drug unintentional overdoses.

    On April 14, 2010, an earthquake reaching 7.1 Richter scale struck Jiegu Town of Yushu. More than 2 698 people were confirmed dead, and 12 135 were injured, of which 1 434 were severely injured. Rescue operation was carried out soon after the disaster; however, the rescue teams face great challenges of altitude hypoxia, freezing temperature and very bad weather. Thus, 1 434 severe injuries were rapidly transported airlifted to hospitals in Xining and neighboring provinces for effective treatment. The extremity trauma (49.9 % ) was the most common patteru of injuries. Asphyxia (40.8 % ) was by far the most important reason for death. A high incidence of acute altitude illness in the lowland rescuers was a special medical problem during the highest earthquake in Yushu. We have learned more lessons from Yushu Earthquake.

  7. Opioid tolerance and the emergence of new opioid receptor-coupled signaling.

    Gintzler, A R; Chakrabarti, S

    2000-01-01

    Multiple cellular adaptations are elicited by chronic exposure to opioids. These include diminution of spare opioid receptors, decreased opioid receptor density, and G-protein content and coupling thereof. All imply that opioid tolefance is a manifestation of a loss of opioid function, i.e., desensitization. Recent observations challenge the exclusiveness of this formulation and indicate that opioid tolerance also results from qualitative changes in opioid signaling. In this article, Gintzler and Chakrabarti discuss the evidence that suggests that opioid tolerance results not only from impaired opioid receptor functionality, but also from altered consequences of coupling. Underlying the latter are fundamental changes in the nature of effectors that are coupled to the opioid receptor/G-protein signaling pathway. These molecular changes include the upregulation of adenylyl cyclase isoforms of the type II family as well as a substantial increase in their phosphorylation state. As a result, there is a shift in opioid receptor/G-protein signaling from predominantly Gialpha inhibitory to Gbetagamma stimulatory following chronic in vivo morphine exposure. These adaptations to chronic morphine indicate the plasticity of opioid-signal transduction mechanisms and the ability of chronic morphine to augment new signaling strategies.

Like other addictive behaviors, risk of opioid misuse may be signaled by an attentional bias (AB) towards drug-related cues. The purpose of this study was to examine opioid AB as a potential predictor of opioid misuse among chronic pain patients following behavioral treatment. Methods Chronic pain patients taking long-term opioid analgesics (N = 47) completed a dot probe task designed to assess opioid AB, as well as self-report measures of opioid misuse and pain severity, and then participated in behavioral treatment. Regression analyses examined opioid AB and cue-elicited craving as predictors of opioid misuse at 3-months posttreatment follow-up. Results Patients who scored high on a measure of opioid misuse risk following treatment exhibited significantly greater opioid AB scores than patients at low risk for opioid misuse. Opioid AB for 200 ms cues and cue-elicited craving significantly predicted opioid misuse risk 20 weeks later, even after controlling for pre-treatment opioid dependence diagnosis, opioid misuse, and pain severity (Model R2 = .50). Conclusion Biased initial attentional orienting to prescription opioid cues and cue-elicited craving may reliably signal future opioid misuse risk following treatment. These measures may therefore provide potential prognostic indicators of treatment outcome. PMID:25282309

    Opioids are widely prescribed pain relievers with multiple side effects and potential complications. They produce analgesia via G-protein-protein coupled receptors: μ-, δ-, κ-opioid and opioid receptor-like 1 receptors. Bivalent ligands targeted to the oligomerized opioid receptors might be the key to developing analgesics without undesired side effects and obtaining effective treatment for opioid addicts. In this review we will update the biological effects of μ-opioids on homo- or hetero-ol...

Overall, numerous genes involved with the pharmacokinetics and dynamics of opioids response are candidate genes in the context of opioid analgesia. The clinical relevance of CYP2D6 genotyping to predict analgesic outcomes is still relatively unknown; the two extremes in CYP2D6 genotype (ultrarapid and poor metabolism seem to predict pain response and/or adverse effects. Overall, the level of evidence linking genetic variability (CYP2D6 and CYP3A4 to oxycodone response and phenotype (altered biotransformation of oxycodone into oxymorphone and overall clearance of oxycodone and oxymorphone is strong; however, there has been no randomized clinical trial on the benefits of genetic testing prior to oxycodone therapy. On the other hand, predicting the analgesic response to morphine based on pharmacogenetic testing is more complex; though there was hope that simple genetic testing would allow tailoring morphine doses to provide optimal analgesia, this is unlikely to occur. A variety of polymorphisms clearly influence pain perception and behavior in response to pain. However, the response to analgesics also differs depending on the pain modality and the potential for repeated noxious stimuli, the opioid prescribed, and even its route of administration.Keywords: pain perception, opioid analgesia, genetic variation, pharmacogenetics

    Abstract Between 2002 and 2007, the nonmedical use of prescription pain relievers grew from 11.0 million to 12.5 million people in the United States. Societal costs attributable to prescription opioid abuse were estimated at $55.7 billion in 2007. The purpose of this study was to comprehensively review the recent clinical and economic evaluations of prescription opioid abuse. A comprehensive literature search was conducted for studies published from 2002 to 2012. Articles were included if they were original research studies in English that reported the clinical and economic burden associated with prescription opioid abuse. A total of 23 studies (183 unique citations identified, 54 articles subjected to full text review) were included in this review and analysis. Findings from the review demonstrated that rates of opioid overdose-related deaths ranged from 5528 deaths in 2002 to 14,800 in 2008. Furthermore, overdose reportedly results in 830,652 years of potential life lost before age 65. Opioid abusers were generally more likely to utilize medical services, such as emergency department, physician outpatient visits, and inpatient hospital stays, relative to non-abusers. When compared to a matched control group (non-abusers), mean annual excess health care costs for opioid abusers with private insurance ranged from $14,054 to $20,546. Similarly, the mean annual excess health care costs for opioid abusers with Medicaid ranged from $5874 to $15,183. The issue of opioid abuse has significant clinical and economic consequences for patients, health care providers, commercial and government payers, and society as a whole.

    Although buprenorphine and methadone are both effective treatments for opioid dependence, their efficacy can vary significantly among patients. Genetic differences may explain some of the variability in treatment outcome. Understanding the interactions between genetic background and pharmacotherapy may result in more informed treatment decisions. This study is a pharmacogenetic analysis of the effects of genetic variants in OPRD1, the gene encoding the δ-opioid receptor, on the prevalence of opioid-positive urine tests in African-Americans (n=77) or European-Americans (n=566) undergoing treatment for opioid dependence. Patients were randomly assigned to treatment with either methadone or buprenorphine/naloxone (Suboxone) over a 24-week open-label clinical trial, in which illicit opioid use was measured by weekly urinalysis. In African-Americans, the intronic SNP rs678849 predicted treatment outcome for both medications. Methadone patients with the CC genotype were less likely to have opioid-positive urine tests than those in the combined CT and TT genotypes group (relative risk (RR)=0.52, 95% confidence interval (CI)=0.44-0.60, p=0.001). In the buprenorphine treatment group, however, individuals with the CC genotype were more likely to have positive opioid drug screens than individuals in the combined CT and TT genotypes group (RR=2.17, 95% CI=1.95-2.68, p=0.008). These findings indicate that the genotype at rs678849 predicts African-American patient response to two common treatments for opioid dependence, suggesting that matching patients to treatment type based on the genotype at this locus may improve overall treatment efficacy. This observation requires confirmation in an independent population.

    Full Text Available Over the past two decades, a steeply growing number of persons with chronic non-cancer pain have been using opioid analgesics chronically to treat it, accompanied by a markedly increased prevalence of individuals with opioid-related misuse, opioid use disorders, emergency department visits, hospitalizations, admissions to drug treatment programs, and drug overdose deaths. This opioid misuse and overdose epidemic calls for well-designed randomized-controlled clinical trials into more skillful and appropriate pain management and for developing effective analgesics which have lower abuse liability and are protective against stress induced by chronic non-cancer pain. However, incomplete knowledge regarding effective approaches to treat various types of pain has been worsened by an under-appreciation of overlapping neurobiological mechanisms of stress, stress-induced relapse to opioid use, and chronic non-cancer pain in patients presenting for care for these conditions. This insufficient knowledge base has unfortunately encouraged common prescription of conveniently-available opioid pain-relieving drugs with abuse liability, as opposed to treating underlying problems using team-based multidisciplinary, patient-centered, collaborative-care approaches for addressing pain and co-occurring stress and risk for opioid use disorder. This paper reviews recent neurobiological findings regarding overlapping mechanisms of stress-induced relapse to opioid misuse and chronic non-cancer pain, and then discusses these in the context of key outstanding evidence gaps and clinical-treatment research directions which may be pursued to fill these gaps. Such research directions, if conducted through well-designed randomized controlled trials, may substantively inform clinical practice in general medical settings on how to effectively care for patients presenting with pain-related distress and these common co-occurring conditions.

This study tests the following hypotheses: (1 there is no strong evidence-based foundation for the conclusion that long-term opioid treatment of chronic nonmalignant pain is effective; and (2 the main problem associated with the safety of such treatment – assessment of the risk of addiction – has been neglected. Methods: Scientometric analysis of the articles representing clinical research in this area was performed to assess (1 the quality of presented evidence (type of study; and (2 the duration of the treatment phase. The sufficiency of representation of addiction was assessed by counting the number of articles that represent (1 editorials; (2 articles in the top specialty journals; and (3 articles with titles clearly indicating that the addiction-related safety is involved (topic-in-title articles. Results: Not a single randomized controlled trial with opioid treatment lasting >3 months was found. All studies with a duration of opioid treatment ≥6 months (n = 16 were conducted without a proper control group. Such studies cannot provide the consistent good-quality evidence necessary for a strong clinical recommendation. There were profound differences in the number of addiction articles related specifically to chronic nonmalignant pain patients and to opioid addiction in general. An inadequate number of chronic pain-related publications were observed with all three types of counted articles: editorials, articles in the top specialty journals, and topic-in-title articles. Conclusion: There is no strong evidence-based foundation for the conclusion that long-term opioid treatment of chronic nonmalignant pain is effective.

    Background Opioid analgesic and benzodiazepine use in individuals with opioid use disorders (OUDs) can increase the risk for medical consequences and relapse. Little is known about rates of use of these medications or prescribing patterns among communities of prescribers. Aims To examine rates of prescribing to Medicaid-enrollees in the calendar year after an OUD diagnosis, and to examine individual, county, and provider community factors associated with such prescribing. Methods We used 2008 Medicaid claims data from 12 states to identify enrollees diagnosed with OUDs, and 2009 claims data to identify rates of prescribing of each drug. We used social network analysis to identify provider communities and multivariate regression analyses to identify patient, county, and provider community level factors associated with prescribing these drugs. We also examined variation in rates of prescribing across provider communities. Results Among Medicaid-enrollees identified with an OUD, 45% filled a prescription for an opioid analgesic, 37% for a benzodiazepine, and 21% for both in the year following their diagnosis. Females, older individuals, individuals with pain syndromes, and individuals residing in counties with higher rates of poverty were more likely to fill prescriptions. Prescribing rates varied substantially across provider communities, with rates in the highest quartile of prescribing communities over 2.5 times the rates in the lowest prescribing communities. Discussion Prescribing opioid analgesics and benzodiazepines to individuals diagnosed with OUDs may increase risk of relapse and overdose. Interventions should be considered that target provider communities with the highest rates of prescribing and individuals at highest risk. PMID:27449904

    Opiate analgesics such as morphine are often used for pain therapy. However, antinociceptive tolerance and dependence may develop with long-term use of these drugs. It was found that μ-opioid receptors can interact with δ-opioid receptors, and morphine antinociceptive tolerance can be reduced by blocking δ-opioid receptors. Recent studies have shown that μ- and δ-opioid receptors are co-expressed in a considerable number of small neurons in the dorsal root ganglion. The interaction of μ-opioid receptors with δ-opioid receptors in the nociceptive afferents is facilitated by the stimulus-induced cell-surface expression of δ-opioid receptors, and contributes to morphine tolerance. Further analysis of the molecular, cellular and neural circuit mechanisms that regulate the trafficking and interaction of opioid receptors and related signalling molecules in the pain pathway would help to elucidate the mechanism of opiate analgesia and improve pain therapy.

    Most pharmaceutical opioids are used to treat pain, and they have been demonstrated to be effective medications for many. Their abuse and misuse pose significant public health concerns in the USA. Research has provided much insight into the prevalence, scope, and drivers of opioid abuse, but a holistic understanding is limited by a lack of available data regarding key aspects of this public health problem. Twelve data gaps were revealed during the creation of a systems-level computer model of medical use, diversion, nonmedical use, and the adverse outcomes associated with opioid analgesics in the USA. Data specific to these gaps would enhance the validity and real-world applications of systems-level models of this public health problem and would increase understanding of the complex system in which use and abuse occur. This paper provides an overview of these gaps, argues for the importance of closing them, and provides specific recommendations for future data collection efforts.

    Study Design Retrospective patient data collection and investigator survey. Purpose To investigate patterns of opioid treatment for pain caused by spinal disorders in Korea. Overview of Literature Opioid analgesic prescription and adequacy of consumption measures in Korea have markedly increased in the past decade, suggesting changing patterns in pain management practice; however, there is lack of integrated data specific to Korean population. Methods Patient data were collected from medical records at 34 university hospitals in Korea. Outpatients receiving opioids for pain caused by spinal disorders were included in the study. Treatment patterns, including opioid types, doses, treatment duration, outcomes, and adverse drug reactions (ADRs), were evaluated. Investigators were interviewed on their perceptions of opioid use for spinal disorders. Results Among 2,468 analyzed cases, spinal stenosis (42.8%) was the most common presentation, followed by disc herniation (24.2%) and vertebral fracture (17.5%). In addition, a greater proportion of patients experienced severe pain (73.9%) rather than moderate (19.9%) or mild (0.7%) pain. Oxycodone (51.9%) and fentanyl (50.8%) were the most frequently prescribed opioids; most patients were prescribed relatively low doses. The median duration of opioid treatment was 84 days. Pain relief was superior in patients with longer treatment duration (≥2 months) or with nociceptive pain than in those with shorter treatment duration or with neuropathic or mixed-type pain. ADRs were observed in 8.6% of cases. According to the investigators' survey, "excellent analgesic effect" was a perceived advantage of opioids, while safety concerns were a disadvantage. Conclusions Opioid usage patterns in patients with spinal disorders are in alignment with international guidelines for spinal pain management. Future prospective studies may address the suitability of opioids for spinal pain treatment by using appropriate objective measurement tools

    Background In opioid dependent youth there is substantial attrition from medication-assisted treatment. If youth at risk for attrition can be identified at treatment entry or early in treatment, they can be targeted for interventions to help retain them in treatment. Methods Opioid dependent adolescents and young adults (n=152), aged 15–21, were randomized to 12 weeks (BUP, n=74) or 2 weeks of detoxification (DETOX, n=78) with buprenorphine/naloxone (Bup/Nal), both in combination with 12 weeks of psychosocial treatment. Baseline and early treatment related predictors of treatment attrition were identified in each group using bivariate and multivariate logistic regression. Results In the DETOX group 36% left between weeks 2 and 4, at the end of the dose taper, while in the BUP group only 8% left by week 4. In the BUP group, early adherence to Bup/Nal, early opioid negative urines, use of any medications in the month prior to treatment entry, and lifetime non-heroin opioid use were associated with retention while prior 30-day hallucinogen use was associated with attrition. In the DETOX group, only use of sleep medications was associated with retention although not an independent predictor. A broad range of other pre-treatment characteristics was unrelated to attrition. Conclusions Prompt attention to those with early non-adherence to medication or an early opioid positive urine, markers available in the first 2 weeks of treatment, may improve treatment retention. Extended Bup/ Nal treatment appeared effective in improving treatment retention for youth with opioid dependence across a wide range of demographics, and pre-treatment clinical characteristics.

    Opioid abuse has continued to increase at an alarming rate since the 1990 s. As documented by different medical specialties, medical boards, advocacy groups, and the Drug Enforcement Administration, available evidence suggests a wide variance in chronic opioid therapy of 90 days or longer in chronic non-cancer pain. Part 1 describes evidence assessment. The objectives of opioid guidelines as issued by the American Society of Interventional Pain Physicians (ASIPP) are to provide guidance for the use of opioids for the treatment of chronic non-cancer pain, to produce consistency in the application of an opioid philosophy among the many diverse groups involved, to improve the treatment of chronic non-cancer pain, and to reduce the incidence of abuse and drug diversion. The focus of these guidelines is to curtail the abuse of opioids without jeopardizing non-cancer pain management with opioids. 1) There is good evidence that non-medical use of opioids is extensive; one-third of chronic pain patients may not use prescribed opioids as prescribed or may abuse them, and illicit drug use is significantly higher in these patients. 2) There is good evidence that opioid prescriptions are increasing rapidly, as the majority of prescriptions are from non-pain physicians, many patients are on long-acting opioids, and many patients are provided with combinations of long-acting and short-acting opioids. 3) There is good evidence that the increased supply of opioids, use of high dose opioids, doctor shoppers, and patients with multiple comorbid factors contribute to the majority of the fatalities. 4) There is fair evidence that long-acting opioids and a combination of long-acting and short-acting opioids contribute to increasing fatalities and that even low-doses of 40 mg or 50 mg of daily morphine equivalent doses may be responsible for emergency room admissions with overdoses and deaths. 5) There is good evidence that approximately 60% of fatalities originate from opioids

    Opioids can induce central sensitization and hyperalgesia, referred to as "opioid-induced hyperalgesia." Our report describes a patient who underwent intestinal transplant followed by immunosuppressant-related neuropathic pain. Her pain was treated with limited success over the course of 3 yr with different therapies, including i.v. morphine. She developed opioid-induced hyperalgesia, which was successfully treated with rapid detoxification under general anesthesia. Detoxification improved her quality of life, including the ability to resume physiotherapy. Six months after treatment, she remained opioid free. Our experience suggests that rapid detoxification under general anesthesia may be an effective treatment for opioid-induced hyperalgesia and merits comparison to traditional detoxification methods.

    Treatment research with opioid-dependent populations has not traditionally distinguished between those dependent on prescription opioids versus dependent upon heroin. Evidence suggests there is a substantial subpopulation of individuals with opioid dependence resulting largely or exclusively from prescription opioid use. Because this subpopulation may respond to treatment differently from heroin users, a method for discriminating DSM-IV opioid dependence due to prescription opioid use would provide more precision when examining this population. This paper describes an innovative method using a currently available diagnostic instrument, to diagnose DSM-IV opioid dependence and distinguish between dependence resulting from prescription opioids versus dependence upon heroin.

    Context Lofexidine is an alpha-2-A noradrenergic receptor agonist that is approved in the United Kingdom for the treatment of opioid withdrawal symptoms. Lofexidine has been reported to have more significant effects on decreasing opioid withdrawal symptoms with less hypotension than clonidine. Objective To demonstrate that lofexidine is well tolerated and effective in the alleviation of observationally-defined opioid withdrawal symptoms in opioid dependent individuals undergoing medically supervised opioid detoxification as compared to placebo. Design An inpatient, Phase 3, placebo-controlled, double blind, randomized multi-site trial with three phases: (1) Opioid Agonist Stabilization Phase (days 1–3), (2) Detoxification/Medication or Placebo Phase (days 4–8), and (3) Post Detoxification/Medication Phase (days 9–11). Subjects Sixty-eight opioid dependent subjects were enrolled at three sites with 35 randomized to lofexidine and 33 to placebo. Main Outcome Measure Modified Himmelsbach Opiate Withdrawal Scale (MHOWS) on study day 5 (2nd opioid detoxification treatment day). Results Due to significant findings, the study was terminated early. On the study day 5 MHOWS, subjects treated with lofexidine had significantly lower scores (equating to fewer/less severe withdrawal symptoms) than placebo subjects (Least squares means 19.5 ± 2.1 versus 30.9 ± 2.7; p=0.0019). Lofexidine subjects had significantly better retention in treatment than placebo subjects (38.2% versus 15.2%; Log rank test p=0.01). Conclusions Lofexidine is well tolerated and more efficacious than placebo for reducing opioid withdrawal symptoms in inpatients undergoing medically supervised opioid detoxification.

    The development of medications for treating persons with opioid use disorders has expanded the number of evidence-based treatment options, particularly for persons with the most severe disorders. It has also improved outcomes compared to psychosocial treatment alone and expanded treatment availability by increasing the number of physicians involved in treatment and the settings where patients can be treated. The medications include methadone, buprenorphine, buprenorphine/naloxone, and extended-release injectable naltrexone. Studies have shown that they are most effective when used over an extended, but as-yet-unspecified, period of time and with counseling and other services, particularly for the many with psychosocial problems. Though controversial in some cultures, well-designed studies in Switzerland, the Netherlands, Germany, and Canada have demonstrated the efficacy of supervised heroin injecting for persons who responded poorly to other treatments, and this treatment option has been approved by Switzerland and a few other E.U. countries. The degree to which medication-assisted therapies are available is dependent on many variables, including national and local regulations, preferences of individual providers and their geographical location, treatment costs, and insurance policies. Greater availability of medication-assisted therapies has become a major focus in the U.S. and Canada, where there has been a marked increase in deaths associated with heroin and prescription opioid use. This paper provides a brief summary of these developments. PMID:28184294

  15. Update on prescription extended-release opioids and appropriate patient selection

    Full Text Available Michael J Brennan The Pain Center of Fairfield, Fairfield, CT, USA Abstract: Chronic pain is largely underdiagnosed, often undertreated, and expected to increase as the American population ages. Many patients with chronic pain require long-term treatment with analgesic medications, and pain management may involve use of prescription opioids for patients whose pain is inadequately controlled through other therapies. Yet because of the potential for abuse and addiction, many clinicians hesitate to treat their patients with pain with potentially beneficial agents. Finding the right opioid for the right patient is the first – often complicated – step. Ensuring that patients continue to properly use the medication while achieving therapeutic analgesic effects is the long-term goal. Combined with careful patient selection and ongoing monitoring, new formulations using extended-release technologies incorporating tamper-resistant features may help combat the growing risk of abuse or misuse, which will hopefully reduce individual suffering and the societal burden of chronic pain. The objective of this manuscript is to provide an update on extended-release opioids and to provide clinicians with a greater understanding of which patients might benefit from these new opioid formulations and how to integrate the recommended monitoring for abuse potential into clinical practice. Keywords: chronic pain, opioid analgesics, extended release, abuse prevention

    Opioid ligands have found use in a number of therapeutic areas, including for the treatment of pain and opiate addiction (using agonists) and alcohol addiction (using antagonists such as naltrexone and nalmefene). The reaction of imines, derived from the opioid ligands oxymorphone and naltrexone, with Michael acceptors leads to pyridomorphinans with structures similar to known pyrrolo- and indolomorphinans. One of the synthesized compounds, 5e, derived from oxymorphone had substantial agonist activity at delta opioid receptors but not at mu and/or kappa opioid receptors and in that sense profiled as a selective delta opioid receptor agonist. The pyridomorphinans derived from naltrexone and naloxone were all found to be non-selective potent antagonists and as such could have utility as treatments for alcohol abuse.

    Full Text Available Evolutionary rescue occurs when a population that is threatened with extinction by an environmental change adapts to the change sufficiently rapidly to survive. Here we extend the mathematical theory of evolutionary rescue. In particular, we model evolutionary rescue to a sudden environmental change when adaptation involves evolution at a single locus. We consider adaptation using either new mutations or alleles from the standing genetic variation that begin rare. We obtain several results: i the total probability of evolutionary rescue from either new mutation or standing variation; ii the conditions under which rescue is more likely to involve a new mutation versus an allele from the standing genetic variation; iii a mathematical description of the U-shaped curve of total population size through time, conditional on rescue; and iv the time until the average population size begins to rebound as well as the minimal expected population size experienced by a rescued population. Our analysis requires taking into account a subtle population-genetic effect (familiar from the theory of genetic hitchhiking that involves "oversampling" of those lucky alleles that ultimately sweep to high frequency. Our results are relevant to conservation biology, experimental microbial evolution, and medicine (e.g., the dynamics of antibiotic resistance.

    medicolegal complications. Conclusion: Cluster analysis suggests that there have been no substantial changes in variables indicating greater severity in this new group of patients. Women are likely to seek help earlier, which reduces their duration of opioid use. The younger the patient, the shorter the duration of opioid use and the greater the likelihood of cessation of intravenous use. Public health systems should use a two-pronged treatment strategy of short but intense cessation therapies for women and younger treatment entrants and longer maintenance and replacement therapies for older treatment entrants with more psychosocial and medical complications.

    Opioids are utilized frequently for the treatment of moderate to severe acute pain in the perioperative setting, as well as in the treatment of cancer-related pain. When prescribing chronic opioid therapy to patients with chronic pain, it is crucial for the practitioner to be aware not only of the issues of tolerance and withdrawal, but also to have knowledge of the possibility for opioid-induced hyperalgesia (OIH). An understanding of the differences between tolerance and OIH when escalating opioid therapy allows the titration of opioid as well as nonopioid analgesics in order to obtain maximum control of both chronic and acute pain. A case study is described to highlight the importance of judicious utilization of opioids in the treatment of cancer-related pain. In this case, high-dose opioid therapy did not improve chronic pain and contributed to a hyperalgesic state in which a young man experienced severe intractable pain postoperatively after two routine thoracotomies, despite aggressive pharmacologic measures to manage his perioperative pain. Furthermore, it illustrates the potential advantages of opioid rotation to methadone when OIH is suspected.

    In recent years, the delta opioid receptor has attracted increasing interest as a target for the treatment of chronic pain and emotional disorders. Due to their therapeutic potential, numerous tools have been developed to study the delta opioid receptor from both a molecular and a functional perspective. This review summarizes the most commonly available tools, with an emphasis on their use and limitations. Here, we describe (1) the cell-based assays used to study the delta opioid receptor. (2) The features of several delta opioid receptor ligands, including peptide and non-peptide drugs. (3) The existing approaches to detect delta opioid receptors in fixed tissue, and debates that surround these techniques. (4) Behavioral assays used to study the in vivo effects of delta opioid receptor agonists; including locomotor stimulation and convulsions that are induced by some ligands, but not others. (5) The characterization of genetically modified mice used specifically to study the delta opioid receptor. Overall, this review aims to provide a guideline for the use of these tools with the final goal of increasing our understanding of delta opioid receptor physiology.

  2. Effect of electroacupuncture on opioid consumption in patients with chronic musculoskeletal pain: protocol of a randomised controlled trial

    Xue Charlie CL

    2012-09-01

    Full Text Available Abstract Background Chronic musculoskeletal pain is common and has been increasingly managed by opioid medications, of which the long-term efficacy is unknown. Furthermore, there is evidence that long-term use of opioids is associated with reduced pain control, declining physical function and quality of life, and could hinder the goals of integrated pain management. Electroacupuncture (EA has been shown to be effective in reducing postoperative opioid consumption. Limited evidence suggests that acupuncture could assist patients with chronic pain to reduce their requirements for opioids. The proposed research aims to assess if EA is an effective adjunct therapy to standard pain and medication management in reducing opioids use by patients with chronic musculoskeletal pain. Methods In this multicentre, randomised, sham-acupuncture controlled, three-arm clinical trial, 316 patients regularly taking opioids for pain control and meeting the defined selection criteria will be recruited from pain management centres and clinics of primary care providers in Victoria, Australia. After a four-week run-in period, the participants are randomly assigned to one of three treatment groups to receive EA, sham EA or no-EA with a ratio of 2:1:1. All participants receive routine pain medication management delivered and supervised by the trial medical doctors. Twelve sessions of semi-structured EA or sham EA treatment are delivered over 10 weeks. Upon completion of the acupuncture treatment period, there is a 12-week follow-up. In total, participants are involved in the trial for 26 weeks. Outcome measures of opioid and non-opioid medication consumption, pain scores and opioid-related adverse events are documented throughout the study. Quality of life, depression, function, and attitude to pain medications are also assessed. Discussion This randomised controlled trial will determine whether EA is of significant clinical value in assisting the management of

    Coloma-Carmona, A; Carballo, J L; Rodríguez-Marín, J; Pérez-Carbonell, A

    To analyse the prevalence in the use and dependence on opioid drugs in the Spanish population with chronic pain and evaluate the differences according to sex. 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. 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. Planning for treatments with opioids and strategies for preventing inappropriate use should not depend on the patient's sex. We need further studies on the medical and psychological variables related to the use of and dependence on opioids.

    Recently, new trend toward non-opioid substances is observed in Iran. This is, therefore, to compare overdose of opioids and non-opioids origin. We performed this investigation to provide more detailed information so that preventive actions are taken in future. Over 18 month, 1876 individuals with opioid (opium, heroin, compact-heroin, buprenorphine and opiates) or non-opioid (MDMA (ecstasy), LSD, hashish and cocaine) overdose were selected. They have been compared regarding sex, age, reason of overdose, method of substance use, occupation, marital status, history of addiction in parents/siblings, duration of hospital admission and educational level. There were 1782 and 94 persons with opioid and non-opioid, respectively. Inhalation was the method of choice and women were found to have more tendencies to hallucinogens rather opioids. Moreover, use of non-opioids was observed more in individuals with university education and moreover in whom none of whose parents/siblings was addict. Policies should be planned by the governments to prevent further addictions especially to non-opioids. Copyright © 2012 Elsevier Ltd and Faculty of Forensic and Legal Medicine. All rights reserved.

    In the aftermath of the 2003 Columbia accident, NASA removed the Hubble Space Telescope (HST) Servicing Mission 4 (SM4) from the Space Shuttle manifest. Reasons cited included concerns that the risk of flying the mission would be too high. The HST SM4 was subsequently reinstated and flown as Space Transportation System (STS)-125 because of improvements in the ascent debris environment, the development of techniques for astronauts to perform on orbit repairs to damaged thermal protection, and the development of a strategy to provide a viable crew rescue capability. However, leading up to the launch of STS-125, the viability of the HST crew rescue capability was a recurring topic. For STS-125, there was a limited amount of time available to perform a crew rescue due to limited consumables (power, oxygen, etc.) available on the Orbiter. The success of crew rescue depended upon several factors, including when a problem was identified; when and what actions, such as powering down, were begun to conserve consumables; and where the Launch on Need (LON) vehicle was in its ground processing cycle. Crew rescue success also needed to be weighed against preserving the Orbiter s ability to have a landing option in case there was a problem with the LON vehicle. This paper focuses on quantifying the HST mission loss of crew rescue capability using Shuttle historical data and various power down strategies. Results from this effort supported NASA s decision to proceed with STS-125, which was successfully completed on May 24th 2009.

    Background Abuse of prescription opioid analgesics is a serious threat to public health, resulting in rising numbers of overdose deaths and admissions to emergency departments and treatment facilities. Absent adequate patient information systems, “doctor shopping” patients can obtain multiple opioid prescriptions for nonmedical use from different unknowing physicians. Our study estimates the prevalence of doctor shopping in the US and the amounts and types of opioids involved. Methods and Findings The sample included records for 146.1 million opioid prescriptions dispensed during 2008 by 76% of US retail pharmacies. Prescriptions were linked to unique patients and weighted to estimate all prescriptions and patients in the nation. Finite mixture models were used to estimate different latent patient populations having different patterns of using prescribers. On average, patients in the extreme outlying population (0.7% of purchasers), presumed to be doctor shoppers, obtained 32 opioid prescriptions from 10 different prescribers. They bought 1.9% of all opioid prescriptions, constituting 4% of weighed amounts dispensed. Conclusions Our data did not provide information to make a clinical diagnosis of individuals. Very few of these patients can be classified with certainty as diverting drugs for nonmedical purposes. However, even patients with legitimate medical need for opioids who use large numbers of prescribers may signal dangerously uncoordinated care. To close the information gap that makes doctor shopping and uncoordinated care possible, states have created prescription drug monitoring programs to collect records of scheduled drugs dispensed, but the majority of physicians do not access this information. To facilitate use by busy practitioners, most monitoring programs should improve access and response time, scan prescription data to flag suspicious purchasing patterns and alert physicians and pharmacists. Physicians could also prevent doctor shopping by

    Despite advances in the treatment of cancer in paediatric patients, 15% of children die from the illness progression in Chile, and pain is the most significant symptom in advanced stages. Although the World Health Organization guidelines demonstrate that opioids are fundamental in pain management, there is still resistance to their use. The main objective of this article was to describe the experience in the use of opioids for pain management in paediatric patients with advanced cancer in palliative care (PC). Retrospective study of patients admitted into the PC Program at the Hospital Roberto del Río between 2002 and 2013. Analysis was carried out on demographic data; oncological diagnosis; pain intensity on admission and discharge, according to validated scales; use of non-steroidal anti-inflammatory drugs; weak opioids; strong opioids; adjuvants drugs; the presence of secondary effects resulting from the use of morphine, and the need for palliative sedation. Of the 99 medical records analysed, the median age was 8 years, 64.6% were male, and there was a similar distribution in three oncological diagnosis groups. Upon admission, 43.4% presented intense to severe pain, and upon discharge there were four patients, but with a maximum VAS score of 7 in only one case. Of the 66 patients taking strong opioids, 89% required less than 0.5mg/kg/hr. Constipation was the most frequently observed secondary effect. Two thirds of the patients studied required strong opioids, with which adequate pain management was achieved, with no serious complications observed. The use of opioids in this group of patients, following a protocol, is considered effective and safe. Copyright © 2015 Sociedad Chilena de Pediatría. Publicado por Elsevier España, S.L.U.

    Here we report the investigation of diazabicycloalkane cores as potential new scaffolds for the development of novel analogues of the previously reported diazatricyclodecane selective delta (δ) opioid agonists, as conformationally constrained homologues of the reference δ agonist (+)-4-[(αR)-α((2S,5R)-4-allyl-2,5-dimethyl-1-piperazinyl)-3-methoxybenzyl]-N,N-diethylbenzamide (SNC80). In particular, we have simplified the diazatricyclodecane motif of δ opioid agonist prototype 1a with bridged bicyclic cores. 3,6-diazabicyclo[3.1.1]heptane, 3,8-diazabicyclo[3.2.1]octane, 3,9-diazabicyclo[3.3.1]nonane, 3,9-diazabicyclo[4.2.1]nonane, and 3,10-diazabicyclo[4.3.1]decane were adopted as core motifs of the novel derivatives. The compounds were synthesized and biologically assayed as racemic (3-5) or diastereoisomeric (6,7) mixtures. All the novel compounds 3-7 showed δ agonism behaviour and remarkable affinity to δ receptors. Amongst the novel derivatives, 3,8-diazabicyclo[3.2.1]octane based compound 4 evidenced improved δ affinity and selectivity relative to SNC80. Published by Elsevier Ltd.

    Most research examining buprenorphine has been conducted with heroin users. Few studies have examined buprenorphine pharmacotherapy for prescription opioid users. Data were from a randomized controlled trial of behavioral treatment provided for 16weeks on a platform of buprenorphine pharmacotherapy and medication management. We compared heroin (H, n=54), prescription opioid (PO, n=54) and combination heroin+prescription opioid (POH, n=71) users to test the hypothesis that PO users will have better treatment outcomes compared with heroin users. The PO group provided more opioid-negative urine drug screens over the combined treatment period (PO:70%, POH:40%, H:38%, pbuprenorphine dose between the groups. PO users appear to have better outcomes in buprenorphine pharmacotherapy compared to those reporting any heroin use, confirming that buprenorphine pharmacotherapy is effective in PO users.

There are three main hypotheses that could explain the increased risk of fracture associated with central analgesics, such as opioids: 1 the increased risk of falls caused by central nervous system effects, including sedation and dizziness; 2 reduced bone mass density caused by the direct opioid effect on osteoblasts; and 3 chronic opioid-induced hypogonadism. The impact of opioids varies by sex and among the type of opioid used (less, for example, for tapentadol and buprenorphine. Opioid-associated androgen deficiency is correlated with an increased risk of osteoporosis; thus, despite that standards have not been established for monitoring and treating opioid-induced hypogonadism or hypoadrenalism, all patients chronically taking opioids (particularly at doses ≥100 mg morphine daily should be monitored for the early detection of hormonal impairment and low bone mass density.

    We report here the design, synthesis, and in vitro characterization of new opioid peptides featuring a 4-anilidopiperidine moiety. Despite the fact that the chemical structures of fentanyl surrogates have been found suboptimal per se for the opioid activity, the corresponding conjugates with opioid peptides displayed potent opioid activity. These studies shed an instructive light on the strategies and potential therapeutic values of anchoring the 4-anilidopiperidine scaffold to different classes of opioid peptides. PMID:23623418

    2012-01-01

    The treatment of pain produced during the management of burn injury has been an ongoing problem for physicians caring for these patients. The main therapeutic option for analgesia has been the repeated and prolonged use of opioids. The adverse effects of opioids are well known but the long term use of opioids which produces tolerance with accompanying dose escalation and dependence is most problematic. Another potentially important consequence of opioid exposure that sometimes masks as tolerance is that of opioid induced hyperalgesia. This syndrome is manifest as enhanced pain, sensitivity and loss of analgesic efficacy in patients treated with opioids who actually become sensitized to painful stimuli. This article focuses on the treatment of burn pain and how current analgesic therapies with opioids may cause hyperalgesia and affect the adequacy of treatment for burn pain. This article also provides possible modalities to help therapeutically manage these patients and considers future analgesic strategies which may help to improve pain management in this complicated patient population.

    2012-03-01

    Breathlessness or "shortness of breath," medically termed dyspnea, remains a devastating problem for many people and those who care for them. As a treatment intervention, administration of opioids to relieve breathlessness is an area where progress has been made with the development of an evidence base. As evidence in support of opioids has accumulated, so has our collective understanding about trial methodology, research collaboration, and infrastructure that is crucial to generate reliable research results for palliative care clinical settings. Analysis of achievements to date and what it takes to accomplish these studies provides important insights into knowledge gaps needing further research and practical insight into design of pharmacological and nonpharmacological intervention trials in breathlessness and palliative care. This article presents the current understanding of opioids for treating breathlessness, what is still unknown as priorities for future research, and highlights methodological issues for consideration in planned studies.

    2001-05-01

    Donepezil, an oral acetylcholinesterase inhibitor approved for the treatment of Alzheimer's disease, was given to 6 cancer pain patients having sedation related to the analgesic use of opioids. Each patient was taking more than 200 mg of oral morphine equivalents per day, and several were receiving complex analgesic regimens consisting of multiple adjuvant medications. Sedation improved at least moderately in 5 of the patients and mildly in 1 after they began taking donepezil. Patients reported a decrease in episodes of spontaneous sleeping during the day, fewer myoclonic twitches, improved daily function and greater social interaction. Several also reported improved sleep at night. Analgesia was not compromised by the use of donepezil, and in some cases it appeared improved. Donepezil may be a valuable alternative to psychostimulants in the treatment of opioid-induced sedation. A prospective controlled trial comparing the treatment effects of psychostimulants and donepezil on patients having opioid-induced sedation is underway.

    To combat the prescription opioid problem, St. Joseph's Healthcare System in Paterson, NJ, has developed a new program that gives providers options they can use to effectively alleviate pain without resorting to highly addictive medication. Launched in January 2016 in the ED at St. Joseph's Regional Medical Center (SJRMC), the Alternatives to Opioids (ALTO) program utilizes protocols that primarily target five common conditions: renal colic, sciatica, headaches, musculoskeletal pain, and extremity fractures. Administrators say they have successfully treated more than 300 patients under the new program, and they see ALTO as a model other hospitals can duplicate. Among the alternative therapies called for in the ALTO program are trigger point injections, nitrous oxide, and ultrasound-guided nerve blocks. ALTO medications are specifically chosen because of how they affect the pain receptor sites for each different pain syndrome. While the primary goal of the program is to use alternatives to opioids when-ever possible, another important underlying goal is to stop acute pain from becoming chronic. While ALTO therapies typically take a bit longer to deliver than prescribing opioids, administrators note that this has not adversely affected patient flow in the ED.

    Full Text Available We examined whether pain outcomes (pain interference, perceived pain treatment effectiveness vary by race and then whether opioid use moderates these associations. These analyses are part of a retrospective cohort study among 3,505 black and 46,203 non-Hispanic, white Department of Veterans Affairs (VA patients with diagnoses of chronic musculoskeletal pain who responded to the 2007 VA Survey of Healthcare Experiences of Patients (SHEP. We used electronic medical record data to identify prescriptions for pharmacologic pain treatments in the year after diagnosis (Pain Diagnosis index visit and before the SHEP index visit (the visit that made one eligible to complete the SHEP; pain outcomes came from the SHEP. We found no significant associations between race and pain interference or perceived effectiveness of pain treatment. VA patients with opioid prescriptions between the Pain Diagnosis index visit and the SHEP index visit reported greater pain interference on the SHEP than those without opioid prescriptions during that period. Opioid prescriptions were not associated with perceived treatment effectiveness for most patients. Findings raise questions about benefits of opioids for musculoskeletal pain and point to the need for alternative treatments for addressing chronic noncancer pain.

    More than 240 million opioid prescriptions are dispensed annually to treat pain in the US. The use of opioids is commonly associated with opioid tolerance (OT) and opioid-induced hyperalgesia (OIH), which limit efficacy and compromise safety. The dearth of effective way to prevent or treat OT and OIH is a major medical challenge. We hypothesized that mesenchymal stem cells (MSCs) attenuate OT and OIH in rats and mice based on the understanding that MSCs possess remarkable anti-inflammatory properties and that both OT and chronic pain are associated with neuroinflammation in the spinal cord. We found that the development of OT and OIH was effectively prevented by either intravenous or intrathecal MSC transplantation (MSC-TP), which was performed before morphine treatment. Remarkably, established OT and OIH were significantly reversed by either intravenous or intrathecal MSCs when cells were transplanted after repeated morphine injections. The animals did not show any abnormality in vital organs or functions. Immunohistochemistry revealed that the treatments significantly reduced activation level of microglia and astrocytes in the spinal cord. We have thus demonstrated that MSC-TP promises to be a potentially safe and effective way to prevent and reverse two of the major problems of opioid therapy.

    Naloxone is a common treatment option for the reversal of an opioid overdose. The law regulating naloxone varies from state to state and therefore so does the drug's availability. The state of Rhode Island has legalized naloxone for over-the-counter use while a number of states allow prescriptions to opioid abusers and family members. The medical community as a whole appears to be divided on the issue of availability to lay persons. This is largely due to a lack of information on this relatively new subject, as well as discrepancies within the existing naloxone research in regard to the use of naloxone among the general public. This literature review provides an objective examination of the pros and cons of increasing the availability of naloxone to the public, with an emphasis on the state of West Virginia (WV). Due to WV's high rates of opioid abuse and overdose, the implications of increasing public accessibility to naloxone could be invaluable in the effort to reduce opioid related deaths. To this end, a WV law that has recently gone into effect allows emergency personnel and family members of opioid addicts to carry naloxone. Ongoing research investigations will determine the impact of this law in regard to the overall wellbeing of the residents of WV and the implications on future laws regulating naloxone use.

    2012-02-03

    When intrathecal and epidural opioids are administered, pruritus occurs as an unwanted and troublesome side effect. The reported incidence varies between 30% and 100%. The exact mechanisms of neuraxial opioid-induced pruritus remain unclear. Postulated mechanisms include the presence of an "itch center" in the central nervous system, medullary dorsal horn activation, and antagonism of inhibitory transmitters. The treatment of intrathecal opioid-induced pruritus remains a challenge. Many pharmacological therapies, including antihistamines, 5-HT(3)-receptor antagonists, opiate-antagonists, propofol, nonsteroid antiinflammatory drugs, and droperidol, have been studied. In this review, we will summarize pathophysiological and pharmacological advances that will improve understanding and ultimately the management of this troublesome problem.

  12. Mu Opioid Splice Variant MOR-1K Contributes to the Development of Opioid-Induced Hyperalgesia.

    Directory of Open Access Journals (Sweden)

    Folabomi A Oladosu

    Full Text Available A subset of the population receiving opioids for the treatment of acute and chronic clinical pain develops a paradoxical increase in pain sensitivity known as opioid-induced hyperalgesia. Given that opioid analgesics are one of few treatments available against clinical pain, it is critical to determine the key molecular mechanisms that drive opioid-induced hyperalgesia in order to reduce its prevalence. Recent evidence implicates a splice variant of the mu opioid receptor known as MOR-1K in the emergence of opioid-induced hyperalgesia. Results from human genetic association and cell signaling studies demonstrate that MOR-1K contributes to decreased opioid analgesic responses and produces increased cellular activity via Gs signaling. Here, we conducted the first study to directly test the role of MOR-1K in opioid-induced hyperalgesia.In order to examine the role of MOR-1K in opioid-induced hyperalgesia, we first assessed pain responses to mechanical and thermal stimuli prior to, during, and following chronic morphine administration. Results show that genetically diverse mouse strains (C57BL/6J, 129S6, and CXB7/ByJ exhibited different morphine response profiles with corresponding changes in MOR-1K gene expression patterns. The 129S6 mice exhibited an analgesic response correlating to a measured decrease in MOR-1K gene expression levels, while CXB7/ByJ mice exhibited a hyperalgesic response correlating to a measured increase in MOR-1K gene expression levels. Furthermore, knockdown of MOR-1K in CXB7/ByJ mice via chronic intrathecal siRNA administration not only prevented the development of opioid-induced hyperalgesia, but also unmasked morphine analgesia.These findings suggest that MOR-1K is likely a necessary contributor to the development of opioid-induced hyperalgesia. With further research, MOR-1K could be exploited as a target for antagonists that reduce or prevent opioid-induced hyperalgesia.

  13. Non-analgesic effects of opioids: opioid-induced respiratory depression.

    Opioids induce respiratory depression via activation of μ-opioid receptors at specific sites in the central nervous system including the pre-Bötzinger complex, a respiratory rhythm generating area in the pons. Full opioid agonists like morphine and fentanyl affect breathing with onset and offset profiles that are primarily determined by opioid transfer to the receptor site, while the effects of partial opioid agonists such as buprenorphine are governed by transfer to the receptor site together with receptor kinetics, in particular dissociation kinetics. Opioid-induced respiratory depression is potentially fatal but may be reversed by the opioid receptor antagonist naloxone, an agent with a short elimination half-life (30 min). The rate-limiting factor in naloxone-reversal of opioid effect is the receptor kinetics of the opioid agonists that requires reversal. Agents with slow dissociation kinetics (buprenorphine) require a continuous naloxone infusion while agents with rapid kinetics (fentanyl) will show complete reversal upon a single naloxone dose. Since naloxone is non-selective and will reverse analgesia as well, efforts are focused on the development of compounds that reverse opioid-induced respiratory depression without affecting analgesic efficacy. Such agents include ampakines and serotonin agonists which are aimed at selectively enhancing central respiratory drive. A novel approach is aimed at the reduction of respiratory depression from opioid-activation of (micro-)glia cells in the pons and brainstem using micro-glia cell stabilizers. Since this approach simultaneously enhances opioid analgesic efficacy it seems an attractive alternative to the classical reversal strategies with naloxone.

Adult patients with CLBP who initiated duloxetine or SOC between November 2010 and April 2011 were identified. Treatment initiation was defined as no pill coverage for duloxetine or SOC in the previous 90 days. Included patients had no opioid use in the 90 days before initiation. Propensity score matching was used to select patients with similar baseline demographic and clinical characteristics for duloxetine and SOC cohorts. Compliance with index medication was assessed via medication possession ratio (MPR and proportion of days covered (PDC for 6 months after initiation. The proportion of patients receiving opioids and days on opioids after index date were assessed, and regression models were estimated to compare opioid use between cohorts. A total of 766 patients initiated duloxetine and 6,206 patients initiated SOC. After matching, 743 patients were selected for the duloxetine (mean age 57 years; female 74% and SOC (mean age 57 years; female 75% cohorts, respectively.

    Cancer pain is complex, and despite the introduction of the WHO cancer pain ladder, few studies have looked at the prevalence of adjuvant medication use in an inpatient palliative medicine unit. In this study, we evaluate the use of adjuvant pain medications in patients admitted to an inpatient palliative care unit and whether their use affects pain scores or opiate dosing. In this retrospective observational study, patients admitted to the inpatient palliative care unit over a 3-month period with a diagnosis of cancer on opioid therapy were selected. Data pertaining to demographics, diagnosis, oral morphine dose equivalent of the opioid at the time of discharge, adjuvant analgesics, nonsteroidal anti-inflammatory drugs (NSAIDs), and pain scores as reported by nurses and physicians were collected. Seventy-seven patients were eligible over a 3-month period, out of which 65 (84 %) were taking an adjuvant medication. The most commonly prescribed adjuvant was gabapentin (70 %). Fifty-seven percent were taking more than one adjuvant. There were more women in the group receiving adjuvants (57 vs. 17%, p = 0.010). Those without adjuvants compared with those on adjuvants did not have worse pain scores on discharge as reported by physicians (0.8 ± 0.8 vs. 1.0 ± 0.7, p = 0.58) or nurses (2.0 ± 2.7 vs. 2.1 ± 2.6, p = 0.86). There was no difference in morphine equivalent doses of the opioid in both groups (median (min, max); 112 (58, 504) vs. 200 (30, 5,040)) at the time of discharge; 75-80 % of patients had improvement in pain scores as measured by a two-point reduction in numerical rating scale (NRS). This study shows that adjuvant medications are commonly used for treating pain in patients with cancer. More than half of study population were on two adjuvants or an adjuvant plus NSAID along with an opioid. We did not demonstrate any benefit in terms of improved pain scores or opioid doses with adjuvants, but this could reflect confounding variables and physician choice

  16. Opioid-Induced Glial Activation: Mechanisms of Activation and Implications for Opioid Analgesia, Dependence, and Reward

    Directory of Open Access Journals (Sweden)

    Mark R. Hutchinson

    2007-01-01

    Full Text Available This review will introduce the concept of toll-like receptor (TLR–mediated glial activation as central to all of the following: neuropathic pain, compromised acute opioid analgesia, and unwanted opioid side effects (tolerance, dependence, and reward. Attenuation of glial activation has previously been demonstrated both to alleviate exaggerated pain states induced by experimental pain models and to reduce the development of opioid tolerance. Here we demonstrate that selective acute antagonism of TLR4 results in reversal of neuropathic pain as well as potentiation of opioid analgesia. Attenuating central nervous system glial activation was also found to reduce the development of opioid dependence, and opioid reward at a behavioral (conditioned place preference and neurochemical (nucleus accumbens microdialysis of morphine-induced elevations in dopamine level of analysis. Moreover, a novel antagonism of TLR4 by (+- and (˗-isomer opioid antagonists has now been characterized, and both antiallodynic and morphine analgesia potentiating activity shown. Opioid agonists were found to also possess TLR4 agonistic activity, predictive of glial activation. Targeting glial activation is a novel and as yet clinically unexploited method for treatment of neuropathic pain. Moreover, these data indicate that attenuation of glial activation, by general or selective TLR antagonistic mechanisms, may also be a clinical method for separating the beneficial (analgesia and unwanted (tolerance, dependence, and reward actions of opioids, thereby improving the safety and efficacy of their use.

  17. Abuse liability in opioid therapy for pain treatment in patients with an addiction history.

    Science.gov (United States)

    Weaver, Michael; Schnoll, Sidney

    2002-01-01

    Patients may present to physicians with complaints of acute or chronic pain. Some of these patients will have a history of addiction to drugs or alcohol, and a few will have active addiction. Controlled-substance prescriptions, especially opioid pain medications, can be very beneficial for treatment of pain in patients. There are clear differences between physical dependence on medication, active addiction, addiction in remission, and pseudoaddiction. A search of the medical literature revealed different rates of addiction in patients with chronic pain because different criteria were used to define addiction and the types of chronic pain. It appears that rates of addiction in patient populations with chronic pain are no different than rates of addiction in the general population, according to some recent studies. "Drug-seeking behavior" may be seen with either active addiction or pseudoaddiction. A way to distinguish between these conditions is by giving the patient more pain medication and observing the patient's pattern of behavior. Some patients may be at higher risk to abuse prescription opioids, and some types of drug-seeking behavior may be more predictive of active addiction than pseudoaddiction. General guidelines can improve physicians' comfort level in prescribing opioids for patients with chronic pain, even those with a history of addiction. These include using a medication agreement or contract, setting appropriate goals with the patient, giving appropriate amounts of pain medication, monitoring with drug screens and pill counts, and documenting the case carefully. Even patients with a history of addiction can benefit from opioid pain medications if the patients are monitored appropriately.

    Lee, Hyeon Jeong; Yeomans, David C

    2014-11-01

    Pain is difficult to investigate and difficult to treat, in part, because of problems in quantification and assessment. The use of opioids, combined with classic anesthetics to maintain hemodynamic stability by controlling responses to intraoperative painful events has gained significant popularity in the anesthetic field. However, several side effects profiles concerning perioperative use of opioid have been published. Over the past two decades, many concerns have arisen with respect to opioid-induced hyperalgesia (OIH), which is the paradoxical effect wherein opioid usage may decrease pain thresholds and increase atypical pain unrelated to the original, preexisting pain. This brief review focuses on the evidence, mechanisms, and modulatory and pharmacologic management of OIH in order to elaborate on the clinical implication of OIH.

  2. Neuraxial Opioid-Induced Itch and Its Pharmacological Antagonism

    Science.gov (United States)

    2015-01-01

    Given its profound analgesic nature, neuraxial opioids are frequently used for pain management. Unfortunately, the high incident rate of itch/pruritus after spinal administration of opioid analgesics reported in postoperative and obstetric patients greatly diminishes patient satisfaction and thus the value of the analgesics. Many endeavors to solve the mystery behind neuraxial opioid-induced itch had not been successful, as the pharmacological antagonism other than the blockade of mu opioid receptors remains elusive. Nevertheless, as the characteristics of all opioid receptor subtypes have become more understood, more studies have shed light on the potential effective treatments. This review discusses the mechanisms underlying neuraxial opioid-induced itch and compares pharmacological evidence in nonhuman primates with clinical findings across diverse drugs. Both nonhuman primate and human studies corroborate that mixed mu/kappa opioid partial agonists seem to be the most effective drugs in ameliorating neuraxial opioid-induced itch while retaining neuraxial opioid-induced analgesia.

  3. Nicotine effects and the endogenous opioid system.

    2014-01-01

    Nicotine (NIC) is an exogenous ligand of the nicotinic acetylcholine receptor (nAChR), and it influences various functions in the central nervous system. Systemic administration of NIC elicits the release of endogenous opioids (endorphins, enkephalins, and dynorphins) in the supraspinal cord. Additionally, systemic NIC administration induces the release of methionine-enkephalin in the spinal dorsal horn. NIC has acute neurophysiological actions, including antinociceptive effects, and the ability to activate the hypothalamic-pituitary-adrenal (HPA) axis. The endogenous opioid system participates in NIC-induced antinociception, but not HPA axis activation. Moreover, NIC-induced antinociception is mediated by α4β2 and α7 nAChRs, while NIC-induced HPA axis activation is mediated by α4β2, not α7, suggesting that the effects of NIC on the endogenous opioid system are mediated by α7, not α4β2. NIC has substantial physical dependence liability. The opioid-receptor antagonist naloxone (NLX) elicits NIC withdrawal after repeated NIC administration, and NLX-induced NIC withdrawal is inhibited by concomitant administration of an opioid-receptor antagonist. NLX-induced NIC withdrawal is also inhibited by concomitant administration of an α7 antagonist, but not an α4β2 antagonist. Taken together, these findings suggest that NIC-induced antinociception and the development of physical dependence are mediated by the endogenous opioid system, via the α7 nAChR.

    Lentil seeds have provided an appreciated source of protein, carbohydrates and fibre to the diet of humans since the dawn of agriculture. Low amounts of variation have been detected in the cultivated lentil germplasm collections. Interspecific crosses allow for the introgression of important alleles of agricultural interest from wild species, such as the resistance or tolerance to abiotic and biotic stresses. Interspecific crosses within the genus Lens generally abort and embryo rescue techniques are necessary to recover hybrids. The in vitro culture procedure to rescue interspecific hybrids of Lens consists of at least four different stages: (1) in ovulo embryo culture (2), embryo culture, (3) plantlet development and finally, (4) the gradual habituation to ex vitro conditions of the recovered interspecific hybrid plantlets. In this chapter, the approach to rescue interspecific hybrids in the genus Lens is outlined.

    As winter backcountry activity increases, so does exposure to avalanche danger. A complicated situation arises when multiple victims are caught in an avalanche and where medical and other rescue demands overwhelm resources in the field. These mass casualty incidents carry a high risk of morbidity and mortality, and there is no recommended approach to patient care specific to this setting other than basic first aid principles. The literature is limited with regard to triaging systems applicable to avalanche incidents. In conjunction with the development of an electronic avalanche rescue training module by the Canadian Avalanche Association, we have designed the Avalanche Survival Optimizing Rescue Triage algorithm to address the triaging of multiple avalanche victims to optimize survival and disposition decisions.

    Helicobacter pylori (H pylori)infection is the main cause of gastritis,gastroduodenal ulcer disease,and gastric cancer.After more than 20 years of experience in Hpylori treatment,in my opinion,the ideal regimen to treat this infection is still to be found.Currently,apart from having to know first-line eradication regimens well,we must also be prepared to face lyeatment failures.Therefore,in designing a treatment strategy we should not focus on the results of primary therapy alone,but also on the final (overall) eradication rate.The choice of a "rescue" treatment depends on which treatment is used initially.If a clarithromycinbased regimen was used initially,a subsequent metronidazole-based treatment (quadruple therapy)may be used afterwards,and then a levofloxacinbased combination would be a third "rescue" option.Alternatively,it has recently been suggested that levofloxacin-based rescue therapy constitutes an encouraging second-line strategy,representing an alternative to quadruple therapy in patients with previous PPI-clarithromycin-amoxicillin failure,with the advantage of efficacy,simplicity and safety.In this case,a quadruple regimen may be reserved as a third-line rescue option.Finally,rifabutin-based rescue therapy constitutes an encouraging empirical fourthline strategy after multiple previous eradication failures with key antibiotics such as amoxicillin,clarithromycin,metronidazole,tetracycline,and levofloxacin.Even after two consecutive failures,several studies have demonstrated that H pylor/eradication can finally be achieved in almost all patients if several rescue therapies are consecutively given.Therefore,the attitude in H pylori eradication therapy failure,even after two or more unsuccessful attempts,should be to fight and not to surrender.

  7. Update on prescription extended-release opioids and appropriate patient selection

    Chronic pain is largely underdiagnosed, often undertreated, and expected to increase as the American population ages. Many patients with chronic pain require long-term treatment with analgesic medications, and pain management may involve use of prescription opioids for patients whose pain is inadequately controlled through other therapies. Yet because of the potential for abuse and addiction, many clinicians hesitate to treat their patients with pain with potentially beneficial agents. Finding the right opioid for the right patient is the first – often complicated – step. Ensuring that patients continue to properly use the medication while achieving therapeutic analgesic effects is the long-term goal. Combined with careful patient selection and ongoing monitoring, new formulations using extended-release technologies incorporating tamper-resistant features may help combat the growing risk of abuse or misuse, which will hopefully reduce individual suffering and the societal burden of chronic pain. The objective of this manuscript is to provide an update on extended-release opioids and to provide clinicians with a greater understanding of which patients might benefit from these new opioid formulations and how to integrate the recommended monitoring for abuse potential into clinical practice.

    Oral normal-release morphine has long been considered the gold-standard treatment for cancer breakthrough pain. However, its relatively long time to analgesic onset, delay in maximal analgesic effect and prolonged duration of action make it unsuitable for the management of breakthrough pain episodes. These limitations led to the development of an oral transmucosal formulation of the fast-acting opioid fentanyl (oral transmucosal fentanyl citrate [OTFC] lozenge on a plastic handle; Actiq®), which has been shown to produce more rapid and effective pain relief than oral morphine. However, the formulation itself has some limitations. Consequently, investigators have continued to develop other, newer generation, transmucosal formulations of fentanyl to further improve the management of breakthrough pain. Recently, five such compounds (Effentora®/Fentora®, Abstral®, Instanyl®, Breakyl®/OnsolisTM and PecFent®) have been concurrently approved in Europe and/or the US, and have documented efficacy in quickly relieving breakthrough pain episodes. All of the available pivotal efficacy trials of these agents are randomized, double-blind comparisons with placebo. There are no head-to-head trials comparing any of the newer transmucosal formulations with each other. Only one non-pivotal study of intranasal fentanyl spray used a transmucosal preparation as an active comparator. However, that comparator was OTFC, not one of the newer transmucosal products. Close examination of the existing trials assessing these newer transmucosal preparations reveals significant variation in many study parameters, such as patient selection criteria, severity of breakthrough pain episodes, proportions of patients with a neuropathic pain component, titration protocols, choice of the primary endpoints, protocols for repeat dosing and rescue medication, the separation of treated episodes and the extent of the placebo response, all of which may have affected efficacy results. It is therefore

    Opioid receptors are widely present in the cell surface of various systems of the body. Opioids which are widely applied in the medical community, have different roles, especially the immune system through the opioid receptor on each organ of the human body. Previous studies have found that most opioids suppress the immune system, while according to the recent research discovery, opioids via opioid receptors plays a dual role on immune system,though the exact mechanism is not fully understood. Here is to make a review on its effects on the immune system and the mechanism.%阿片受体广泛存在于人体各个系统的细胞表面.阿片类物质在医学界广泛应用,阿片受体对人体各个器官有着不同的作用,尤其是免疫系统.以往的研究发现阿片类物质多是抑制免疫系统功能,新近研究发现,阿片类物质通过阿片受体对免疫系统产生双重作用,但具体机制尚不完全清楚.现就其对免疫系统的影响及机制加以阐述.

    Naloxone reversal of opioid-induced respiratory depression outside of medical facilities has become more prevalent because of the escalating opioid epidemic in the USA. Take-home naloxone for treatment of opioid emergencies is now being recommended by numerous federal, state, and professional organizations. Areas covered: The scope of the opioid overdose epidemic is reviewed along with practical, clinical, regulatory, and usability considerations for take-home naloxone routes of administration currently available and associated delivery systems. Specific opioid-related factors are discussed in detail with emphasis placed on life-threatening respiratory depression and naloxone antagonism. A clinical overview, including pharmacokinetic and FDA approval information for each take-home naloxone product is discussed in detail as well as the impact of take-home naloxone in the community. Finally, given these products are to be used in a panic-stricken, life-threatening opioid emergency, an analysis of available usability data is provided with proposed directions for further study. Expert opinion: Based on the available clinical evidence, auto-injectable naloxone should be the preferred administration route for take-home naloxone treatment until additional safety, efficacy, and comparative outcomes data are available for unconventional routes of administration that unequivocally provide equal or superior results.

    To examine the effects of opioid and tissue-damaging procedures (TDPs) [i.e. procedures performed in the neonatal intensive care unit (NICU) known to result in pain, stress, and tissue damage] on brain metabolites, we reviewed the medical records of 28 asphyxiated term neonates (eight opioid-treated, 20 non-opioid treated) who had undergone magnetic resonance imaging (MRI) and proton magnetic resonance spectroscopy (MRS) within the first month of life as well as eight newborns with no clinical findings of asphyxial injury. We found that lower creatine (Cr), myoinositol (Ins), and N-acetylaspartate (NAA)/choline (Cho) (p OGM) NAA/Cr was decreased (p = 0.03) and lactate (Lac) was present in a significantly higher amount (40%; p = 0.03) in non-opioid-treated neonates compared with opioid-treated neonates. Compared with controls, untreated neonates showed larger changes in more metabolites in basal ganglia (BG), thalami (TH), and OGM with greater significance than treated neonates. Our data suggest that TDPs affect spectral metabolites and that opioids do not cause harm in asphyxiated term neonates exposed to repetitive TDPs in the first 2-4 DOL and may provide a degree of neuroprotection.

    We examine current applications of the moral duty to rescue to justify clinical investigators' duties of ancillary care and standard of care to subjects in resource-poor settings. These applications fail to explain why investigators possess obligations to research participants, in particular, and not to people in need, in general. Further, these applications fail to recognize the normative significance of the institutional role of the investigators. We offer a positive account of the duty to rescue for investigators as institutional agents, with duties to populations rather than merely individuals.

    Opioids are not generally deemed to have an analgesic ceiling effect on cancer pain. However, there have been occasional reports of tolerance to opioid development induced by multiple doses of fentanyl. The authors report a case of suspected tolerance to the analgesic effect of opioid, in which an increasing dose of fentanyl failed to relieve the patient's cancer pain symptoms, but opioid switching to oxycodone injections enabled a dose reduction to below the equivalent dose conversion ratio. The patient was a 60-year-old man diagnosed with pancreatic body carcinoma with multiple metastases. The base dose consisted of 12 mg/day of transdermal fentanyl patches (equivalent to 3.6 mg/day, 150 μg/h fentanyl injection), and rescue therapy consisted of 10 mg immediate-release oxycodone powders. Despite the total daily dose of fentanyl reaching 5.6 mg (equivalent to 560 mg oral morphine), the analgesic effect was inadequate; thus, an urgent adjustment was necessary. Due to the moderate dose of fentanyl, the switch to oxycodone injection was done incrementally at a daily dose equivalent to 25% of the fentanyl injection. The total dose of oxycodone was replaced approximately 53.5% of the dose of fentanyl prior to opioid switching.

    Full Text Available Health political background: Methadone substitution treatment in Germany is introduced in 1988 in the framework of a scientific pilot study in North Rhein Westphalia. Recent statistics show that by now a broad offer of substitution treatment exists. From 1 June 2002 to 31 December 2003 113,000 substitution treatments have been recorded as being started of which around 56,000 have been recorded as ongoing treatments by 1 December 2003. Scientific background: Substitution treatment (treatment of opioid-dependent persons using substitution substances is one part of addiction treatment. Its goals are harm reduction and the stabilisation of opioid dependent persons. Integration of opioid-dependent persons in a treatment-setting, reduction of consumption of psychoactive substances, reduction of risk behaviour (primarily related to infectious diseases, decrease of mortality and improvements concerning the social, psychic and physic situation are seen as a success of substitution treatment as maintenance therapy. Research questions: The aim of this HTA report is to investigate which indicators can be used to evaluate the effectiveness of substitution treatment. Based on these indicators an evaluation of the medical, social and economical benefit of substitution treatment - also in relation to abstinence oriented treatment - is carried out. Methods: A systematic literature search was performed in 31 international databases which yielded 2451 articles with publication date between 1995 and February 2005. Results: After a twofold selection process 32 publications were included for assessment and 276 publications were used as background literature. Despite serious restrictions due to selection bias and dropout in most studies focusing on substitution treatment, reduction of consumption of illegal opioids, reduction of risk behaviour, criminal behaviour, mortality and incidence of HIV can be seen as an empirically proven success of substitution treatment

    Full Text Available Abstract Background After a long and controversial debate methadone maintenance treatment (MMT was first introduced in Germany in 1987. The number of patients in MMT – first low because of strict admission criteria – increased considerably since the 1990s up to some 65,000 at the end of 2006. In Germany each general practitioner (GP, who has completed an additional training in addiction medicine, is allowed to prescribe substitution drugs to opioid dependent patients. Currently 2,700 GPs prescribe substitution drugs. Psychosocial care should be made available to all MMT patients. Results The results of research studies and practical experiences clearly indicate that patients benefit substantially from MMT with improvements in physical and psychological health. MMT proves successful in attaining high retention rates (65 % to 85 % in the first years, up to 50 % after more than seven years and plays a major role in accessing and maintaining ongoing medical treatment for HIV and hepatitis. MMT is also seen as a vital factor in the process of social re-integration and it contributes to the reduction of drug related harms such as mortality and morbidity and to the prevention of infectious diseases. Some 10 % of MMT patients become drug-free in the long run. Methadone is the most commonly prescribed substitution medication in Germany, although buprenorphine is attaining rising importance. Access to MMT in rural areas is very patchy and still constitutes a problem. There are only few employment opportunities for patients participating in MMT, although regular employment is considered unanimously as a positive factor of treatment success. Substitution treatment in German prisons is heterogeneous in access and treatment modalities. Access is very patchy and the number of inmates in treatment is limited. Nevertheless, substitution treatment plays a substantial part in the health care system provided to drug users in Germany. Conclusion In Germany, a

    Angiogenesis is an important characteristic of cancer. Switching from the avascular phase to the vascular phase is a necessary process for tumor growth. Therefore, research in cancer treatment has focused on angiogenesis as a drug target. Despite the widespread use of opioids to treat pain in patients with cancer, little is known about the effect of these drugs on vascular endothelium and angiogenesis. We aimed to investigate the efficacies of morphine, codeine, and tramadol in 3 different concentrations on angiogenesis in hens' eggs. This is a prospective, observational, controlled, in-vivo animal study. Single academic medical center. This study was conducted on the chorioallantoic membrane (CAM) of fertilized hens' eggs. The efficacies of morphine, codeine, and tramadol in 3 different concentrations were evaluated on angiogenesis in a total of 165 hens' eggs. Statistically significant differences were found between drug-free agarose used as a negative control and concentrations of morphine of 10 µM and 1 µM, a concentration of tramadol of 10 µM, and concentrations of codeine of 10 µM and 1 µM. Concentrations of morphine of 10 µM and 1 µM showed strong antiangiogenic effects. While codeine had strong antiangiogenic effects at high concentrations, at 0.1 µM it was shown to have weak antiangiogenic effects. However, tramadol at a concentration of 10 µM had only weak antiangiogenic effects. This is just a CAM model study. In this study, we tested the effects of 3 different opioid drugs on angiogenesis in 3 different concentrations, and we observed that morphine was a good anti-angiogenic agent, but tramadol and codeine only had anti-angiogenic effects at high doses.Key Words: Morphine, codeine, tramadol, opioid, bevacizumab, chorioallantoic membrane (CAM), angiogenesis.

    Background Athletes with injury-related pain, especially National Football League (NFL) players, are at increased risk for opioid use and misuse which may result in medical, psychiatric and social problems. This is the first study to evaluate the intersection of sports pain and opioid use and misuse among former NFL players. Methods A telephone survey of 644 retired NFL players from the 2009 Retired Players Association Directory was conducted (53.4% completion rate) from March to August 2010. Results Over half (52%) used opioids during their NFL career with 71% reporting misuse. Additionally, 15% of NFL misusers currently misused vs. 5% among players who used just as prescribed during their NFL career. Prevalence of current opioid use was 7%--3 times the rate of the general population. Multivariate analyses indicated that significant NFL pain increased the adjusted odds (AOR) of any current opioid use vs. non-use (AOR 6.76, 95%CI 2.88-15.87), as did moderate to severe mental impairment (AOR 1.88, 95%CI 1.19-2.98) and heavy drinking in the past week (AOR 2.15, 95% CI 1.17-3.98). Undiagnosed concussions singly predicted current misuse vs. use just as prescribed (AOR 4.25, 95%CI 1.12-16.22). Three variables predicted current misuse vs. non-use: significant pain (AOR 8.33, 95%CI 1.98-35.04), undiagnosed concussions (AOR 3.51, 95%CI 1.98-35.04) and heavy drinking (AOR 3.48, 95%CI 1.63-7.41). Conclusions Players who misused during their NFL career were most likely to misuse currently compared to others. Current misuse was associated with more NFL pain, undiagnosed concussions and heavy drinking. Longitudinal studies are needed to determine the long term effects of opioid misuse among athletes.

    Full Text Available Sofie Mauger,1 Ronald Fraser1,2 Kathryn Gill1,2 1Department of Psychiatry, McGill University, Montreal, QC, Canada; 2Addictions Unit, McGill University Health Centre, Montreal, QC, Canada Objectives: To review current evidence on buprenorphine–naloxone (bup/nx for the treatment of opioid-use disorders, with a focus on strategies for clinical management and office-based patient care. Quality of evidence: Medline and the Cochrane Database of Systematic Reviews were searched. Consensus reports, guidelines published, and other authoritative sources were also included in this review. Apart from expert guidelines, data included in this review constitute level 1 evidence. Findings: Bup/nx is a partial µ-opioid agonist combined with the opioid antagonist naloxone in a 4:1 ratio. It has a lower abuse potential, carries less stigma, and allows for more flexibility than methadone. Bup/nx is indicated for both inpatient and ambulatory medically assisted withdrawal (acute detoxification and long-term substitution treatment (maintenance of patients who have a mild-to-moderate physical dependence. A stepwise long-term substitution treatment with regular monitoring and follow-up assessment is usually preferred, as it has better outcomes in reducing illicit opioid use, minimizing concomitant risks such as human immunodeficiency virus and hepatitis C transmission, retaining patients in treatment and improving global functioning. Conclusion: Bup/nx is safe and effective for opioid detoxification and substitution treatment. Its unique pharmaceutical properties make it particularly suitable for office-based maintenance treatment of opioid-use disorder.

    Polydrug abuse is a known problem among opioid-dependent patients receiving opioid maintenance treatment (OMT). However, improved laboratory diagnostics is required to reveal polydrug abuse in its current scope. Furthermore, there are few studies focusing on the relationship between polydrug abuse and adequacy of the dose of OMT medicine. This study aimed to evaluate the polydrug abuse among opioid-dependent patients receiving OMT with inadequate (Group IA) and adequate (Group A) doses of OMT medicine as experienced by the patients. Craving for opioids and withdrawal symptoms were evaluated as indicators of the adequacy rating. This is a retrospective register-based study of 60 OMT patients on either methadone or sublingual buprenorphine/naloxone medication, whose polydrug abuse was studied from urine samples by means of a comprehensive high-resolution mass spectrometry method. Inadequate doses of the OMT medicines were associated with higher subjective withdrawal scores and craving for opioids. Six groups of abused substances (benzodiazepines, amphetamines, opioids, cannabis, new psychoactive substances, and non-prescribed psychotropic medicines) were found among OMT patients. Group IA patients showed significantly more abuse of benzodiazepines and amphetamines than the Group A patients. All the new psychoactive substances and most of the non-prescribed psychotropic medicines were detected from the Group IA patients. There was no difference in the doses of the OMT medicine between Groups IA and A patients. Polydrug abuse, detected by definitive laboratory methods, was widespread and more common among Group IA than Group A patients, emphasizing the requirement for individual OMT medicine dose adjustment.

    Full Text Available Temporal lobe epilepsy is considered to be one of the most common and severe forms of focal epilepsies. Patients often develop cognitive deficits and emotional blunting along the progression of the disease. The high incidence of resistance to antiepileptic drugs and a frequent lack of admissibility to surgery poses an unmet medical challenge. In the urgent quest of novel treatment strategies, neuropeptides are interesting candidates, however, their therapeutic potential has not yet been exploited. This review focuses on the functional role of the endogenous opioid system with respect to temporal lobe epilepsy, specifically in the hippocampus. The role of dynorphins and kappa opioid receptors (KOPr as modulators of neuronal excitability is well understood: both the reduced release of glutamate as well of postsynaptic hyperpolarization were shown in glutamatergic neurons. In line with this, low levels of dynorphin in humans and mice increase the risk of epilepsy development. The role of enkephalins is not understood so well. On one hand, some agonists of the delta opioid receptors (DOPr display pro-convulsant properties probably through inhibition of GABAergic interneurons. On the other hand, enkephalins play a neuro-protective role under hypoxic or anoxic conditions, most probably through positive effects on mitochondrial function. Despite the supposed absence of endorphins in the hippocampus, exogenous activation of the mu opioid receptors (MOPr induces pro-convulsant effects. Recently-expanded knowledge of the complex ways opioid receptors ligands elicit their effects (including biased agonism, mixed binding, and opioid receptor heteromers, opens up exciting new therapeutic potentials with regards to seizures and epilepsy. Potential adverse side effects of KOPr agonists may be minimized through functional selectivity. Preclinical data suggest a high potential of such compounds to control seizures, with a strong predictive validity toward human

Recently-expanded knowledge of the complex ways opioid receptors ligands elicit their effects (including biased agonism, mixed binding, and opioid receptor heteromers), opens up exciting new therapeutic potentials with regards to seizures and epilepsy. Potential adverse side effects of KOPr agonists may be minimized through functional selectivity. Preclinical data suggest a high potential of such compounds to control seizures, with a strong predictive validity toward human patients. The

    Multimorbidity results in complex polypharmacy which may bear a risk of drug interactions. A better understanding of opioid analgesics combination therapy used for pain management could help warrant medication safety, efficacy, and economic relevance. Until now there has been no review summarizing the opioid analgesics-related pharmacokinetic drug interactions from the perspective of evidence based on randomized controlled trials (RCTs). A literature search was performed using PubMed, MEDLINE, and the Cochrane Library, using a PRISMA flowchart. Fifty-two RCTs were included for data interpretation. Forty-two RCTs (80.8%) were conducted in healthy volunteers, whereas 10 RCTs (19.2%) enrolled true patients. None of the opioid-drug/herb pairs was listed as contraindications of opioids involved in this review. Circumstances in which opioid is comedicated as a precipitant drug include morphine-P2Y12 inhibitors, morphine-gabapentin, and methadone-zidovudine. Circumstances in which opioid is comedicated as an object drug include rifampin-opioids (morphine, tramadol, oxycodone, methadone), quinidine-opioids (morphine, fentanyl, oxycodone, codeine, dihydrocodeine, methadone), antimycotics-opioids (buprenorphine, fentanyl, morphine, oxycodone, methadone, tilidine, tramadol), protease inhibitors-opioids (ritonavir, ritonavir/lopinavir-oxycodone, ritonavir-fentanyl, ritonavir-tilidine), grapefruit juice-opioids (oxycodone, fentanyl, methadone), antidepressants-opioids (paroxetine-tramadol, paroxetine-hydrocodone, paroxetine-oxycodone, escitalopram-tramadol), metoclopramide-morphine, amantadine-morphine, sumatriptan-butorphanol nasal sprays, ticlopidine-tramadol, St John's wort-oxycodone, macrolides/ketolides-oxycodone, and levomepromazine-codeine. RCTs investigating the same combination, almost unanimously, drew consistent conclusions, except two RCTs on amantadine-intravenous morphine combination where a different amantadine dose was used and two RCTs on morphine

    We created an operational definition of possible opioid shopping in US commercial health insurance data and examined its correlates. The population consisted of 264,204 treatment courses in persons with a fill for an opioid or diuretic prescription in 2012 and a second within 18 months. We examined counts of prescribers and pharmacies and the numbers of fills and overlaps for ability to discriminate courses of opioids from diuretics, which were a negative control. The most discriminatory measure, indicating possible shopping behavior, was cross-tabulated against other prescriptions filled and diagnoses as found in insurance claims. The associations between claims characteristics and shopping behavior were assessed in a logistic regression. A definition that classified possible "moderate" or "extensive" shopping when a person obtained drug through at least three practices and at least three pharmacies over 18 months was highly discriminatory between opioid and diuretic treatment. Overlaps between fills and number of fills did not improve the discrimination. Data from insurance claims strongly predicted moderate-to-extensive levels of possible shopping (c=0.82). Prominent among 20 significant predictors were: state of residence; amount of opioid dispensed; self-payment; use of non-specialist prescribers; high use of anxiolytics, hypnotics, psychostimulants and antipsychotics; use of both immediate release (IR) and extended-release or long-acting (ER/LA) opioids. The use of three or more prescribing practices and three or more dispensing pharmacies over 18 months sharply discriminated courses of opioid treatment from courses of diuretics. This pattern of fills was additionally associated with the numbers of non-specialist and self-paid fills, the total MEQ dispensed and heavier use of drugs for anxiety, sleep, attention and psychosis.

    To provide absolute and relative risk estimates of neonatal abstinence syndrome (NAS) based on duration and timing of prescription opioid use during pregnancy in the presence or absence of additional NAS risk factors of history of opioid misuse or dependence, misuse of other substances, non-opioid psychotropic drug use, and smoking. Observational cohort study. Medicaid data from 46 US states. Pregnant women filling at least one prescription for an opioid analgesic at any time during pregnancy for whom opioid exposure characteristics including duration of therapy: short term (opioid prescriptions, corresponding to an absolute risk of 5.9 per 1000 deliveries (95% confidence interval 5.6 to 6.2). Long term opioid use during pregnancy resulted in higher absolute risk of NAS per 1000 deliveries in the presence of additional risk factors of known opioid misuse (220.2 (200.8 to 241.0)), alcohol or other drug misuse (30.8 (26.1 to 36.0)), exposure to other psychotropic medications (13.1 (10.6 to 16.1)), and smoking (6.6 (4.3 to 9.6)) than in the absence of any of these risk factors (4.2 (3.3 to 5.4)). The corresponding risk estimates for short term use were 192.0 (175.8 to 209.3), 7.0 (6.0 to 8.2), 2.0 (1.5 to 2.6), 1.5 (1.0 to 2.0), and 0.7 (0.6 to 0.8) per 1000 deliveries, respectively. In propensity score matched analyses, long term prescription opioid use compared with short term use and late use compared with early use in pregnancy demonstrated greater risk of NAS (risk ratios 2.05 (95% confidence interval 1.81 to 2.33) and 1.24 (1.12 to 1.38), respectively). Use of prescription opioids during pregnancy is associated with a low absolute risk of NAS in the absence of additional risk factors. Long term use compared with short term use and late use compared with early use of prescription opioids are associated with increased NAS risk independent of additional risk factors. © Desai et al 2015.

  9. Minimizing extinction risk through genetic rescue

    Full Text Available According to the genetic rescue hypothesis, immigrants can improve population persistence through their genetic contribution alone. We investigate the potential for such rescue using small, inbred laboratory populations of the bean beetle (Callosobruchus maculatus. We ask how many migrants per generation (MPG are needed to minimize the genetic component of extinction risk. During Phase 1, population size was made to fluctuate between 6 and 60 (for 10 generations. During this phase, we manipulated the number of MPG, replacing 0, 1, 3, or 5 females every generation with immigrant females. During Phase 2, we simply set an upper limit on population size (.10. Compared with the 0-MPG treatment, the other treatments were equivalently effective at improving reproductive success and reducing extinction risk. A single MPG was sufficient for genetic rescue, apparently because effective migration rate was inflated dramatically during generations when population size was small. An analysis of quasi-extinction suggests that replicate populations in the 1-MPG treatment benefited from initial purging of inbreeding depression. Populations in this treatment performed so well apparently because they received the dual benefit of purging followed by genetic infusion. Our results suggest the need for further evaluation of alternative schemes for genetic rescue.

    Classical human memory studies investigating the acquisition of temporally-linked events have found that the memories for two events will interfere with each other and cause forgetting (i.e., interference; Wixted, 2004). Importantly, sleep helps consolidate memories and protect them from subsequent interference (Ellenbogen, Hulbert, Stickgold, Dinges, & Thompson-Schill, 2006). We asked whether sleep can also repair memories that have already been damaged by interference. Using a perceptual learning paradigm, we induced interference either before or after a consolidation period. We varied brain states during consolidation by comparing active wake, quiet wake, and naps with either non-rapid eye movement sleep (NREM), or both NREM and REM sleep. When interference occurred after consolidation, sleep and wake both produced learning. However, interference prior to consolidation impaired memory, with retroactive interference showing more disruption than proactive interference. Sleep rescued learning damaged by interference. Critically, only naps that contained REM sleep were able to rescue learning that was highly disrupted by retroactive interference. Furthermore, the magnitude of rescued learning was correlated with the amount of REM sleep. We demonstrate the first evidence of a process by which the brain can rescue and consolidate memories damaged by interference, and that this process requires REM sleep. We explain these results within a theoretical model that considers how interference during encoding interacts with consolidation processes to predict which memories are retained or lost.

    Prescription opioid analgesics are an important treatment option for patients with chronic pain; however, misuse, abuse and diversion of these medications are a major global public health concern. Prescription opioid analgesics can be abused via intended and non-intended routes of administration, both intact or after manipulation of the original formulation to alter the drug-delivery characteristics. Available data indicate that ingestion (with or without manipulation of the prescribed formulation) is the most prevalent route of abuse, followed by inhalation (snorting, smoking and vaping) and injection. However, reported routes of abuse vary considerably between different formulations. A number of factors have been identified that appear to be associated with non-oral routes of abuse, including a longer duration of abuse, younger age, male sex and a rural or socially deprived location. The development of abuse-deterrent formulations of prescription opioid analgesics is an important step toward reducing abuse of these medications. Available abuse-deterrent formulations aim to hinder extraction of the active ingredient, prevent administration through alternative routes and/or make abuse of the manipulated product less attractive, less rewarding or even aversive. There are currently five opioid analgesics with a Food and Drug Administration abuse-deterrent label, and a number of other products are under review. A growing body of evidence suggests that introduction of abuse-deterrent opioid analgesics in the USA has been associated with decreased rates of abuse of these formulations. The availability of abuse-deterrent formulations therefore appears to represent an important step toward curbing the epidemic of abuse of prescription opioid analgesics, while ensuring the availability of effective pain medications for patients with legitimate medical need.

    Risk assessment and stratification have become a central issue in prescribing opioids to patients with chronic pain. Research to date on various risk screening measures has shown that a clinical interview by an experienced clinician offers superior predictive ability in identifying patients who are more likely to engage in future medication aberrant behavior. The current study represents a pilot study of an interview rating scale that is designed to replicate this clinical assessment. This study compares the predictions of medication aberrant behavior made by the Opioid Risk Tool, the Screener and Opioid Assessment for Patients with Pain-Revised, and the new interview rating scale, the Brief Risk Interview (BRI). A sample of 196 patients was assessed by each of the three risk measures and then follow-up data were gathered at 6 months post interview to determine which patients had engaged in medication aberrant behavior and had been discharged from the practice. The BRI shows superior predictive ability in identifying patients who later engage in medication aberrant behavior. Although more study in other settings is needed, these preliminary data suggest that the Brief Risk Interview could be a useful tool for any pain clinician in assessing risk through the use of information gathered in a brief interview.
