Pain, negative affective states and opioid-based analgesics: Safer pain therapies to dampen addiction.

Across centuries and civilizations opioids have been used to relieve pain. In our modern societies, opioid-based analgesics remain one of the most efficient treatments for acute pain. However, the long-term use of opioids can lead to the development of analgesic tolerance, opioid-induced hyperalgesia, opioid use disorders, and overdose, which can ultimately produce respiratory depressant effects with fatal consequences. In addition to the nociceptive sensory component of pain, negative affective states arising from persistent pain represent a risk factor for developing an opioid use disorder. Several studies have indicated that the increase in prescribed opioid analgesics since the 1990s represents the root of our current opioid epidemic. In this review, we will present our current knowledge on the endogenous opioid system within the pain neuroaxis and the plastic changes occurring in this system that may underlie the occurrence of pain-induced negative affect leading to misuse and abuse of opioid medications. Dissecting the allostatic neuronal changes occurring during pain is the most promising avenue to uncover novel targets for the development of safer pain medications. We will discuss this along with current and potential approaches to treat pain-induced negative affective states that lead to drug misuse. Moreover, this chapter will provide a discussion on potential avenues to reduce the abuse potential of new analgesic drugs and highlight a basis for future research and drug development based on recent advances in this field.

Postoperative Opioid Usage Following Outpatient Arthroscopic Sports Medicine Procedures

Opioid-based analgesia is effective and widely prescribed in elective outpatient orthopaedic procedures. However, there has been simultaneous growth in both the number of opioid analgesic prescriptions and abuse of opioid medications in the United States. There is a paucity of literature examining the quantity of opioids prescribed following common orthopaedic sports procedures as well as the average number of opioid pills consumed and the amount remaining after discontinuation.

Opioid tapering in patients with prescription opioid use disorder: A retrospective study

Background and aimsOpioid use disorder (OUD) refers to a maladaptive pattern of opioid use leading to clinically significant impairment or distress. OUD causes, and vice versa, misuses and abuse of opioid medications. Clinicians face daily challenges to treat patients with prescription opioid use disorder. An evidence-based management for people who are already addicted to opioids has been identified as the national priority in the US; however, options are limited in clinical practices. In this study, we aimed to explore the success rate and important adjuvant medications in the medication assisted treatment with temporary use of methadone for opioid discontinuation in patients with prescription OUD. MethodsThis is a retrospective chart review performed at a private physician office for physical medicine and rehabilitation. We reviewed all medical records dated between December 1st, 2011 and August 30th, 2016. The initial evaluation of the included patients (N=140) was completed between December 1st, 2011 and December 31st, 2014. They all have concumittant prescription OUD and chronic non-cancer pain. The patients (87 female and 53 male) were 46.7±12.7 years old, and had a history of opioid use of 7.7±6.1 years. All patients received the comprehensive opioid taper treatments (including interventional pain management techniques, psychotherapy, acupuncture, physical modalities and exercises, and adjuvant medications) on top of the medication assisted treatment using methadone (transient use). Opioid tapering was considered successful when no opioid medication was used in the last patient visit. ResultsThe 140 patients had pain of 9.6±8.4 years with 8/10 intensity before treatment which decreased after treatment in all comparisons (p<0.001 for all). Opioids were successfully tapered off in 39 (27.9%) patients after 6.6±6.7 visits over 8.8±7.2 months; these patients maintained opioid abstinence over 14.3±13.0 months with regular office visits. Among the 101 patients with unsuccessful opioid tapering, 13 patients only visited the outpatient clinic once. Significant differences were found between patients with and without successful opioid tapering in treatment duration, number of clinic visits, the use of mirtazepine, bupropion, topiramate, and trigger point injections with the univariate analyses. The use of mirtazepine (OR, 3.75; 95% CI, 1.48–9.49), topiramate (OR, 5.61; 95% CI, 1.91–16.48), or bupropion (OR, 2.5; 95% CI, 1.08–5.81) was significantly associated with successful opioid tapering. The associations remain significant for mirtazepine and topiramate (not bupropion) in different adjusted models. ConclusionsWith comprehensive treatments, 27.9% of patients had successful opioid tapering with opioid abstinence for over a year. The use of mirtazepine, topiramate, or likely bupropion was associated with successful opioid tapering in the medication assisted treatment with temporary use of methadone. Opioid tapering may be a practical option and should be considered for managing prescription OUD. ImplicationsFor patients with OUD, indefinite opioid maintenance treatment may not be necessary. Considering the ethical values of autonomy, nonmaleficence, and beneficence, clinicians should provide patients with OUD the option of opioid tapering.

Identifying and assessing the risk of opioid abuse in patients with cancer: an integrative review

BackgroundThe 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.AimsTo 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 methodsOur 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.ResultsWe found 691 articles and eliminated 657, because they were predominantly non cancer 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.ConclusionScreening 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, greater health care utilization, and symptom burden.

Correlates of Nonmedical Use of Hydromorphone and Hydrocodone

Over the past decade, the misuse and abuse of opioid medications in the United States has risen dramatically. Although data show a substantial variation in the nonmedical use of individual opioids, relatively little is known about risk factors for the nonmedical use of specific opioid products. This study compared the prevalence and correlates of the nonmedical use of oral immediate-release hydromorphone (marketed under the brand name of Dilaudid), versus that of hydrocodone combination products using a nationally representative sample of the civilian noninstitutionalized United States population aged 12 years or older. Data were from the 2003 National Survey on Drug Use and Health. An estimated 31.3 million individuals reported lifetime nonmedical use of an opioid analgesic. Of these, 2.9 percent reported lifetime nonmedical use of Dilaudid, and 51.9 percent reported lifetime nonmedical use of hydrocodone combination products exclusive of nonmedical Dilaudid use. Nonmedical Dilaudid users were likely to be older, Caucasian, and to have reported a higher lifetime prevalence of heroin, cocaine and injection drug use, as well as nonmedical use of other opioids. Nonmedical Dilaudid users were at higher risk for engaging in more serious substance abuse-related behaviors than those who reported lifetime nonmedical use of hydrocodone combination products.

Development of opioid formulations with limited diversion and abuse potential

Non-medical abuse of prescription opioid medications is not a new phenomenon, but such use has been increasing in recent years. Various methods have been used and continue to be developed in an effort to limit diversion and abuse of opioid medications. A number of these methods will be described for opioid analgesic and addiction treatment formulations using relevant historical examples (e.g. propoxyphene, pentazocine, buprenorphine) as well as examples of formulations currently being considered or under development (e.g. oxycodone plus naltrexone, sustained-release buprenorphine). The focus, though not exclusively, will be on those formulations that represent a combination of an opioid agonist with an antagonist. These methods must take into consideration the pharmacokinetic profile of the agonist and antagonist, the expected primary route of abuse of the medication and the medication combination, the dose of medication that is likely to be abused, the availability of alternative drugs of abuse, and the population of potential abusers that is being targeted with the revised formulation.
