Treatment Of Opioid Use Disorder Research Articles

Expanding the opioid use disorder medication treatment workforce in rural communities through the RCORP initiative.

The Rural Communities Opioid Response Program (RCORP) was funded to help rural communities improve prevention, treatment, and recovery services for Opioid Use Disorder (OUD), including increasing the supply of clinicians with a Drug Enforcement Administration (DEA) waiver to prescribe buprenorphine, which was required before 2023. This research investigates the impact of RCORP funding on the supply of DEA-waivered clinicians in rural communities. We used 2017-2022 DEA lists of waivered clinicians to assign clinicians to US counties. Using RCORP service area data, we classified rural counties as either being served by an RCORP grantee or not. We calculated the number of counties in each category with a waivered clinician, clinician-to-population ratios, and treatment slot-to-population ratios. In 2017, 3.7% more of RCORP funded counties had a waivered clinician than non-RCORP counties. RCORP counties also had 1.2 more waivered clinicians per 100,000 population and 57.5 more treatment slots per 100,000 population compared to non-RCORP counties. From 2017 to 2022, these differences more than doubled. The supply of waivered clinicians varied across Census Divisions. In most Census Divisions, a greater percentage of RCORP counties had a waivered clinician as well as more waivered clinicians and treatment slots per population, except for the Pacific Census Division, which had more clinicians and treatment slots per population in non-RCORP counties. Study findings suggest that federal investments to expand rural OUD patients' access to care may have been successful, but only if increases in clinician supply translate into greater provision of OUD treatment.

Ibogaine administration following repeated morphine administration upregulates myelination markers 2', 3'-cyclic nucleotide 3'-phosphodiesterase (CNP) and myelin basic protein (MBP) mRNA and protein expression in the internal capsule of Sprague Dawley rats.

Ibogaine is a psychedelic alkaloid being investigated as a possible treatment for opioid use disorder. Ibogaine has a multi-receptor profile with affinities for mu and kappa opioid as well as NMDA receptors amongst others. Due to the sparsity of research into ibogaine's effects on white matter integrity and given the growing evidence that opioid use disorder is characterized by white matter pathology, we set out to investigate ibogaine's effects on two markers of myelination, 2', 3'-cyclic nucleotide 3'-phosphodiesterase (CNP) and myelin basic protein (MBP). Fifty Sprague Dawley rats were randomly assigned to five experimental groups of n = 10; (1) a saline control group received daily saline injections for 10 days, (2) a morphine control group received escalating morphine doses from 5 to 15 mg/kg over 10 days, (3) an ibogaine control group that received 10 days of saline followed by 50 mg/kg ibogaine hydrochloride, (4) a combination morphine and ibogaine group 1 that received the escalating morphine regime followed by 50 mg/kg ibogaine hydrochloride and (5) a second combination morphine and ibogaine group 2 which followed the same morphine and ibogaine regimen yet was terminated 72 h after administration compared to 24 h in the other groups. White matter from the internal capsule was dissected and qPCR and western blotting determined protein and gene expression of CNP and MBP. Morphine upregulated CNPase whereas ibogaine alone had no effect on CNP mRNA or protein expression. However, ibogaine administration following repeated morphine administration had an immediate effect by increasing CNP mRNA expression. This effect diminished after 72 h and resulted in a highly significant upregulation of CNPase protein at 72 h post administration. Ibogaine administration alone significantly upregulated protein expression yet downregulated MBP mRNA expression. Ibogaine administration following repeated morphine administration significantly upregulated MBP mRNA expression which increased at 72 h post administration resulting in a highly significant upregulation of MBP protein expression at 72 h post administration. These findings indicate that ibogaine is able to upregulate genes and proteins involved in the process of remyelination following opioid use and highlights an important mechanism of action of ibogaine's ability to treat substance use disorders.

Mindfulness-Oriented Recovery Enhancement: Implementing an evidence-based intervention for chronic pain, opioid use, and opioid addiction in clinical settings.

The opioid crisis emerged in part due to the overprescribing of opioid analgesics for chronic pain. Although not the only source of the current epidemic of opioid use disorder (OUD), the prescription of opioids for chronic pain remains one vector for the development of opioid misuse and OUD. However, opioid tapering is not appropriate for all patients, and some patients may need to remain on opioid therapy for the long term. To reduce the risk of opioid-related harm among people with chronic pain and to treat incipient or entrenched addictive behaviours, new interventions are needed. This review discusses the clinical outcomes, biobehavioural mechanisms and implementation considerations for a novel, evidence-based intervention for chronic pain, opioid use and OUD called Mindfulness-Oriented Recovery Enhancement (MORE). MORE unites complementary aspects of mindfulness training, cognitive behavioural therapy and principles from positive psychology to simultaneously address addictive behaviour, emotion dysregulation and chronic pain by targeting brain reward and stress systems. MORE has been tested in 13 completed randomized clinical trials, including over 1300 patients, and has demonstrated efficacy against a range of active control conditions for reducing opioid dosing, opioid misuse, illicit drug use, depression, post-traumatic stress symptoms and chronic pain. Opportunities for implementing MORE include facilitating opioid tapering and promoting safe opioid use in primary care and specialty pain clinics, decreasing opioid misuse and enhancing medication-assisted treatment for OUD. Given evidence of MORE's efficacy, it is now time to consider disseminating this evidence-based treatment in the United States, the United Kingdom and worldwide.

Reconsidering the usefulness of long-term high-dose buprenorphine.

Buprenorphine has been successfully used for decades in the treatment of opioid use disorder, yet there are complexities to its use that warrant attention to maximize its utility. While the package insert of the combination product buprenorphine\naloxone continues to recommend a maximum dose of 16 mg daily for maintenance, the emergence of fentanyl and synthetic analogs in the current drug supply may be limiting the effectiveness of this standard dose. Many practitioners have embraced and appropriately implemented novel practices to mitigate the sequelae of our current crisis. It has become common clinical practice to stabilize patients with 24 - 32 mg of buprenorphine daily at treatment initiation. Many of these patients, however, are maintained on these high doses (>16 mg/d) indefinitely, even after prolonged stability. Although this may be a necessary strategy in the short term, there is little evidence to support its safety and efficacy, and these high doses may be exposing patients to more complications and side effects than standard doses. Commonly known side effects of buprenorphine that are likely dose-related include hyperhidrosis, sedation, decreased libido, constipation, and hypogonadism. There are also complications related to the active metabolite of buprenorphine (norbuprenorphine) which is a full agonist at the mu opioid receptor and does not have a ceiling on respiratory suppression. Such side effects can lead to medical morbidity as well as decreased medication adherence, and we, therefore, recommend that after a period of stabilization, practitioners consider a trial of decreasing the dose of buprenorphine toward standard dose recommendations. Some patients' path of recovery may never reach this stabilization phase (i.e., several months of adherence to medications, opioid abstinence, and other clinical indicators of stability). Side effects of buprenorphine may not have much salience when patients are struggling for survival and safety, but for those who are fortunate enough to advance in their recovery, the side effects become more problematic and can limit quality of life and adherence.

Perceptions of Women in Opioid Recovery Regarding Policies and Laws on Sexual and Reproductive Health

ObjectiveTo explore perceptions of policies and laws on sexual and reproductive health among women in recovery from opioid use disorder (OUD). DesignQualitative descriptive. SettingTelephone interviews conducted in a midsized urban area in the midwestern region of the United States. ParticipantsTwenty-two women ages 18 to 49 years who self-identified as being in recovery from OUD. MethodsWe conducted individual, semistructured telephone interviews and analyzed the data using reflexive thematic analysis. ResultsWe identified three themes: Barriers to OUD Treatment and Recovery, Pregnancy as a Gateway to Treatment and Recovery, and The Dobbs Effect. Participants described OUD treatment barriers such as inadequate recovery resources for women and the criminalization of drug use. Many participants described pregnancy as a gateway to recovery because of improved access to treatment services and enhanced motivation for engaging in recovery. Participants described unintended pregnancy as a threat to recovery that made them seek woman-controlled contraceptive methods they could use without negotiating with a partner (e.g., intrauterine devices) after the Supreme Court overturned constitutionally protected access to abortion. ConclusionOpioid use disorder is a public and mental health crisis in the United States that affects reproductive-age women. Participants in our study closely connected recovery from OUD with sexual and reproductive health policy and laws. There is a need for regulation to support the unique needs of women in OUD treatment. The recent Supreme Court decision that overturned constitutionally protected abortion creates challenges for women in recovery from OUD. Nurses are ideally positioned to advocate for recovery and sexual and reproductive health policies and laws that improve the physical and mental health of women in recovery.

Challenges with current diagnosis and treatment strategies for precipitated opioid withdrawal in the emergency department and the role of the pharmacist.

In an effort to expedite the publication of articles, AJHP is posting manuscripts online as soon as possible after acceptance. Accepted manuscripts have been peer-reviewed and copyedited, but are posted online before technical formatting and author proofing. These manuscripts are not the final version of record and will be replaced with the final article (formatted per AJHP style and proofed by the authors) at a later time. To demonstrate the challenges with current diagnosis and treatment strategies for precipitated opioid withdrawal secondary to naloxone the emergency department (ED) setting and describe the role of the emergency medicine (EM) pharmacist in its management. There are no standardized criteria to define precipitated opioid withdrawal syndrome, so the diagnosis is typically based on sentinel signs and symptoms and time course. Complicating factors include a positive urine toxicology screen for nonopioid substances, comorbidities and associated medications prior to admission, medications given in the ED, and a fluctuating patient course during the ED stay that likely involves all these issues. Although buprenorphine is frequently recommended as the primary treatment for precipitated withdrawal, its use can be complicated if patients are on methadone maintenance or other long-acting opioids. The EM pharmacist plays a key role in managing patients with precipitated withdrawal. Practice changes related to the diagnosis and treatment of opioid use disorder (OUD) with precipitated withdrawal in the ED are needed. EM pharmacists as part of the interprofessional care team have an important role in the management of patients with OUD, including those patients undergoing possible precipitated withdrawal.

Patient experiences of buprenorphine dispensing from a mobile medical unit

BackgroundOverdose deaths continue to rise within the United States, despite effective treatments such as buprenorphine and methadone for opioid use disorder (OUD). Mobile medical units with the ability to dispense buprenorphine have been developed to engage patients and eliminate barriers to accessing OUD treatment. This study reports survey responses of patients of a mobile medical unit dispensing buprenorphine in areas of Chicago, IL with high overdose rates.MethodsAll patients who were dispensed buprenorphine via the mobile medical unit were invited to participate in a 7-item anonymous survey between May 24, 2023, and August 25, 2023. The survey included 5-point satisfaction scale, multiple-choice, and open-ended questions. Outcomes included satisfaction with buprenorphine dispensing from the mobile medical unit, satisfaction with filling buprenorphine at a pharmacy in the past, barriers experienced at pharmacies when filling buprenorphine, and whether the client would have started treatment that day if the mobile medical unit had not been present. Satisfaction scale and multiple-choice question responses were assessed using descriptive statistics. Wilcoxon signed-rank test was used to compare median satisfaction levels between receiving buprenorphine from the mobile medical unit versus filling a buprenorphine prescription at a community pharmacy. Open-ended questions were analyzed qualitatively using inductive thematic analysis.Results106 unique patients were dispensed buprenorphine from the mobile unit during the study period. Of these patients, 54 (51%) completed the survey. Respondents reported high satisfaction with the buprenorphine dispensing process as a part of a mobile medical unit. Of those who had previously filled buprenorphine at a pharmacy, 83% reported at least one barrier, with delays in prescription dispensing from a community pharmacy, lack of transportation to/from the pharmacy, and opioid withdrawal symptoms being the most common barriers. 87% reported they would not have started buprenorphine that same day if the mobile medical unit had not been present. Nearly half of survey participants reported having taken buprenorphine that was not prescribed to them. Qualitative analysis of open-ended survey responses noted the importance of convenient accessibility, comprehensive care, and a non-judgmental environment.ConclusionsMobile medical units that dispense buprenorphine are an innovative model to reach patients with OUD who have significant treatment access barriers. This study found that patients who experienced barriers to accessing buprenorphine from a pharmacy were highly satisfied with the mobile medical unit’s buprenorphine dispensing process. Programs seeking to develop mobile buprenorphine dispensing programs should consider patient priorities of accessibility, comprehensive care, and welcoming, non-judgmental environments.

Use and perceptions of Cannabidiol among individuals in treatment for opioid use disorder

BackgroundCannabidiol (CBD) is a widely available cannabis product with many claims as to potential health benefits including alleviating symptoms related to opioid use disorder (OUD). However, little is known as to how individuals with OUD perceive CBD, to what extent they may already be using CBD, and for what purposes.MethodsA survey was conducted among individuals receiving treatment for OUD at the Addiction Institute of Mount Sinai in New York City from July 2021 to August 2023. The survey consisted of demographic questions, questions about opioid use, CBD use, and perceptions regarding CBD. Statistical analysis using ordinal logistic regression was employed to compare perceptions between CBD users and non-users while adjusting for age and race.ResultsAmong 587 respondents, 550 completed the survey. Among all survey completers, 129 (23%) reported a history of using CBD for a variety of reasons including: anxiety (81, 62.8%), pain (65, 50.4%), sleep (63, 48.8%), depression (62, 48.1%), recreational purposes (32, 24.8%), or for other reasons (8, 6.2%). Of note, 22 (17.1%) respondents reported using CBD to control their addiction and 54 (41.9%) reported using CBD to ease opioid withdrawal symptoms. CBD users demonstrated more positive perceptions regarding its legality (β = 0.673, OR = 1.960, 95% CI [1.211, 3.176], p = .006), social acceptance (β = 0.718, OR = 2.051, 95% CI [1.257, 3.341], p = .004), and therapeutic potential compared to non-users. CBD users also had a more positive view of its potential future role in managing addiction (β = 0.613, OR = 1.846, 95% CI [1.181, 2.887], p = .007).ConclusionsThis study highlights a significant association between CBD usage and progressive views regarding CBD among individuals with OUD, suggesting a growing interest in CBD as a potential adjunctive therapy for individuals in substance use treatment. Some patients are already using CBD for anxiety, pain, sleep, depression, or as a harm reduction intervention to control their addiction or for opioid withdrawal symptoms. These findings underscore the importance of integrating patient perspectives into future research and treatment strategies involving CBD in the context of OUD.

Assessing predictors of adequate individual buprenorphine maintenance dosage for the treatment of opioid use disorder: Listening to the patient

ObjectiveDose optimization plays a key role in determining clinical outcomes in patients on opioid agonist treatment (OAT). The objective of this study was to identify the variables independently associated with buprenorphine/naloxone (B/N) dose adequacy in patients with opiate use disorder (OUD). MethodCross-sectional study of a convenience sample of patients with OUD treated with B/N (n = 315) in four regions in Spain. The Opiate Dosage Adequacy Scale (ODAS) was used to determine B/N dose adequacy. The ODAS evaluate the six components of the “dose adequacy” construct, as follows: continued use of heroin; narcotic blockade or crossed tolerance; objective opioid withdrawal symptoms (OWS); subjective OWS; craving for heroin; and overmedication. A binomial logistic regression analysis was performed to identify the variables associated with the condition “ODAS Adequate B/N dose”. Participants completed a battery of instruments to assess sociodemographic, substance use, clinical, and treatment variables. ResultsThe B/N dose was considered adequate in 231 of the 315 participants (73.3 %). Two variables, satisfaction with B/N as a medication (OR=5.764, 95 % CI=2.211-15.030) and patient-perceived participation in B/N dose decisions (OR=1.790, 95 % CI=1221-2623), were independently, significantly, and positively associated with the “ODAS Adequate B/N dose” condition. While the severity of heroin dependence was significantly associated with buprenorphine dose adequacy in the bivariate analyses, significance was lost in the full regression model. ConclusionSatisfaction with B/N as a medication and patient-perceived involvement in the dose decision are associated with clinician-assessed dose adequacy. In the context of good clinical practice, it is important to take into account both of these variables to individualize the prescribed dose through a shared decision-making process.

Estrogen receptor beta signaling enhances extinction memory recall for heroin-conditioned cues in a sex- and region-specific manner

Return to use, or relapse, is a major challenge in the treatment of opioid use disorder (OUD). Relapse can be precipitated by several factors, including exposure to drug-conditioned cues. Identifying successful treatments to mitigate cue-induced relapse has been challenging, perhaps due to extinction memory recall (EMR) deficits. Previously, inhibition of estradiol (E2) signaling in the basolateral amygdala (BLA) impaired heroin-cue EMR. This effect was recapitulated by antagonism of BLA estrogen receptors (ER) in a sex-specific manner such that blocking ERα in males, but ERβ in females, impaired EMR. However, it is unclear whether increased E2 signaling, in the BLA or systemically, enhances heroin-cue EMR. We hypothesized that ERβ agonism would enhance heroin-cue EMR in a sex- and region-specific manner. To determine the capacity of E2 signaling to improve EMR, we pharmacologically manipulated ERβ across several translationally designed experiments. First, male and female rats acquired heroin or sucrose self-administration. Next, during a cued extinction session, we administered diarylpropionitrile (DPN, an ERβ agonist) and tested anxiety-like behavior on an open field. Subsequently, we assessed EMR in a cue-induced reinstatement test and, finally, measured ERβ expression in several brain regions. Across all experiments, females took more heroin and sucrose than males and had greater responses during heroin-cued extinction. Administration of DPN in the BLA enhanced EMR in females only, driven by ERβ’s impacts on memory consolidation. Interestingly, however, systemic DPN administration improved EMR for heroin cues in both sexes across several different tests, but did not impact sucrose-cue EMR. Immunohistochemical analysis of ERβ expression across several different brain regions showed that females only had greater expression of ERβ in the basal nucleus of the BLA. Here, in several preclinical experiments, we demonstrated that ERβ agonism enhances heroin-cue EMR and has potential utility in combatting cue-induced relapse.
