AbstractPersons suffering from opioid use disorder (OUD) experience long-lasting dysphoric symptoms well into extended periods of withdrawal. This protracted withdrawal syndrome is notably characterized by heightened anxiety. Here we investigate if an exacerbated withdrawal model of acute morphine dependence results in lasting behavioral adaptation 6 weeks into forced abstinence. We found that our exacerbated morphine withdrawal paradigm produced distinct impairments in elevated-plus maze, open field, and social interaction tests in male and female mice. These findings will be relevant for future investigation examining the neural mechanisms underlying these behaviors, and will aid in uncovering physiological sex differences in response to opioid withdrawal.

Withdrawal Behaviors

Opioid Use Disorder (OUD) is a chronic and relapsing psychiatric condition which is currently the leading cause of accidental death in the US. Symptoms of acute opioid withdrawal resemble a flu-like illness which is accompanied by a dysphoric state. Psychological comorbidities such as anxiety, depression, and disordered sleep can persist for months or years, well into the abstinence period. These symptoms are thought to drive further opioid intake in order to alleviate this unpleasant internal state. Many differences in OUD have been documented between male and female patients, with females at higher risk for relapse and overdose. This study sets out to characterize sex differences in symptoms and behavioral adaptations in mice during early withdrawal. Using our moderate dose, three-day precipitated withdrawal paradigm, we discovered significant effects of sex, time, and drug treatment on early withdrawal behaviors, locomotor activity, and gut motility in C57BL/6J mice. Here I will discuss previous methods of condensing behavioral phenotypes into one global withdrawal score, and propose a new methodology. This method increases the ability to detect nuanced effects and allows for more accurate translation across strain, sex, paradigm, and experimental context. Classification of opioid withdrawal-induced behavioral adaptations will allow for improved behavioral analysis of pharmacological manipulations, and investigations of brain circuitry involved in opioid withdrawal, as well as future screening of compounds with potential therapeutic benefit for the treatment of OUD.

AbstractPatients suffering from opioid use disorder often relapse during periods of abstinence, which is posited to be caused by negative affective states that drive motivated behaviors. Here, we explored whether conditioning mice with morphine in a CPP training paradigm evoked anxietylike behavior during morphine abstinence. To do this, mice were conditioned with morphine (10 mg/kg, i.p.) for five days. 24 h following conditioning, anxiety levels were tested by measuring time in the open arms of the elevated plus maze. The next day, mice were placed in the three compartment chamber to measure morphine-induced conditioned place preference (CPP). Our results show that following morphine conditioning, mice spent significantly less time in the open arm of the elevated plus maze and expressed robust morphine CPP on CPP test day. Furthermore, we found that an acute treatment with (R,S)-ketamine (10 mg/kg, i.p.), a medication demonstrating promise for preventing anxiety-related phenotypes, 30 min. prior to testing on post conditioning day 1, increased time spent in the open arm of the elevated plus maze in saline- and morphine-conditioned mice. Additionally, we found that a second injection of ketamine 30 min. prior to CPP tests on post conditioning day 2 prevented morphine-induced CPP, which lasted for up to 28 d post conditioning. Furthermore, we found that conditioning mice with 10% (w/v) sucrose using an oral self-administration procedure did not evoke anxietylike behavior, but elicited robust CPP, which was attenuated by ketamine treatment 30 min. prior to CPP tests. Overall, our results suggest that the ketamine-induced block of morphine CPP may not be attributed solely to alleviating negative affective states, but potentially through impaired memory of morphine-context associations.

BACKGROUND: The United States is experiencing an opioid epidemic. Better approaches to encourage outpatient utilization of Food and Drug Administration–approved medications for the treatment of opioid use disorder, including extended-release naltrexone (XR-NTX), are needed. Withdrawal management before initiation of XR-NTX is challenging for clinicians and patients and represents a major barrier to treatment. AIMS: To review psychoeducational strategies that support patients during outpatient withdrawal management and transition to XR-NTX. METHOD: We reviewed the literature on psychoeducational strategies used during opioid withdrawal management and described the role that nurses can play in facilitating transition to XR-NTX in a Phase 3, placebo-controlled, outpatient trial comparing induction regimens. RESULTS: Supportive interventions include general psychoeducation on addiction, overcoming ambivalence, treatment adherence, anticipating XR-NTX induction, managing psychological and physiological aspects of opioid withdrawal, risks of opioid use, and sources of support during recovery. CONCLUSIONS: Psychoeducational strategies led by nurses can promote treatment adherence during withdrawal management and induction onto XR-NTX.

Kratom (Mitragyna speciosa, Korth.) is an evergreen tree that is indigenous to Southeast Asia. When ingested, kratom leaves or decoctions from the leaves have been reported to produce complex stimulant and opioid-like effects. For generations, native populations in Southeast Asia have used kratom products to stave off fatigue, improve mood, alleviate pain and manage symptoms of opioid withdrawal. Despite the long history of kratom use in Asia, it is only within the past 10–20 years that kratom has emerged as an important herbal agent in the United States, where it is being used for the self-treatment of pain, opioid withdrawal symptoms, and mood disorders. The increase in the use of kratom in the United States has coincided with the serious epidemic of opioid abuse and dependence. Since 2015, efforts to restrict access to prescription opioids have resulted in a marked increase in the use of “street” opioids such as heroin and illicit fentanyl. At the same time, many patients with chronic pain conditions or opioid use disorder have been denied access to appropriate medical help. The lack of access to care for patients with chronic pain and opioid use disorder has been magnified by the emergence of the COVID-19 pandemic. In this report, we highlight how these converging factors have led to a surge in interest in kratom as a potential harm reduction agent in the treatment of pain and opioid use disorder.

AbstractIbogaine is a naturally occurring psychedelic medicine with anti-addictive properties. While research on ibogaine is limited, several observational studies have shown ibogaine can mitigate opioid withdrawal, as seen with reductions in clinical and subjective opioid withdrawal scores and reduced drug use severity (Noller, Frampton, & Yazar-Klosinski, 2018; Brown & Alper 2018). Furthermore, the psychoactive experience may help individuals to realign their values, purpose and sense of connection, as seen with post treatment reductions in depression scores (Noller et al., 2018; Mash et al., 2000).Case seriesThis case series describes two cases of individuals accessing ibogaine through private unregulated clinics in the Vancouver area to treat their opioid use disorder.ConclusionsIn case 1, the client achieved total abstinence from all opioids within 5–6 days of starting ibogaine treatment, did not experience any opioid withdrawal symptoms after ibogaine treatment and maintained abstinence from opioids for 3 years. In case 2, the patient took ibogaine/iboga in multiple treatments over a short period of time (<4 months). The patient stopped all non-medical opioids after the first iboga treatment and then used ibogaine to aid with further dose reductions of her opioid agonist therapy (OAT) and has maintained abstinence from opioids for 2 years. Ibogaine offers a unique and novel therapeutic approach to treating opioid use disorder. Further studies are needed to establish the safety, risks and potential role for ibogaine as a mainstream, evidence-based addiction treatment.
