Quality of life of patients treated with opium tincture or methadone: A randomized controlled trial.

OBJECTIVE: Quality of life (QoL) is an increasingly recognized patient-centered treatment outcome in individuals with opioid use disorder. There is a gap in literature on the impact of opium tincture (OT) on patients' QoL compared to standard treatment options such as methadone. This study aimed to compare the QoL of participants with opioid use disorder receiving OAT using OT or methadone and identify the factors associated with their QoL during treatment. METHODS: The opium trial was a multicenter non-inferiority randomized clinical trial in four private OAT outpatient clinics in Iran. The study assigned patients to either OT (10 mg/ml) or methadone sirup (5 mg/ml) for a follow-up of 85 days. QoL was assessed using the brief version of the World Health Organization Quality of Life instrument (WHOQOL- BREF). RESULTS: A total of 83 participants, 35 (42.2%) in the OT arm and 48 (57.8%) in the methadone arm, completed the WHOQOL-BREF in full and were included in the primary analysis. The mean score of patients' QoL showed improvement compared to baseline, but differences were not statistically significant between OT and methadone arms (p = 0.786). Improvements were mainly observed within the first 30 days of receiving treatment. Being married and lower psychological distress were associated with an improved QoL. Within the social relationships domain, male gender showed significantly higher QoL compared to females. CONCLUSION: OT shows promise as an OAT medication, comparable to methadone in improving patients' QoL. There is a need to incorporate psychosocial interventions to further sustain and improve the QoL in this population. Identifying other social determinants of health which affect QoL and the cultural adaptation of assessments for individuals from various ethnocultural backgrounds are critical areas of inquiry.

Development of a Graphene-Oxide-Deposited Carbon Electrode for the Rapid and Low-Level Detection of Fentanyl and Derivatives.

The opioid overdose crisis in North America worsened during the COVID-19 pandemic, with multiple jurisdictions reporting more deaths per day due to the fentanyl-contaminated drug supply than COVID-19. The rapid quantitative detection of fentanyl in the illicit opioid drug supply or in bodily fluids at biologically relevant concentrations (i.e., <80 nM) remains a significant challenge. Electroanalytical techniques are inexpensive and can be used to rapidly detect fentanyl, but detection limits need to be improved. Herein, we detail the development of an electrochemical-based fentanyl analytical detection strategy that used a glassy carbon electrode modified with electrochemically reduced graphene oxide (ERGO) via electrophoretic deposition. The resulting surface was further electrochemically reduced in the presence of fentanyl to enhance the sensitivity. Multiple ERGO thicknesses were prepared in order to prove the versatility and ability to fine-tune the layer to the desired response. Fentanyl was detected at <10 ppb (<30 nM) with a limit of detection of 2 ppb and a calibration curve that covered 4 orders of concentration (from 1 ppb to 10 ppm). This method was sensitive to fentanyl analogues such as carfentanil. Interference from the presence of 100-fold excess of other opioids (heroin, cocaine) or substances typically found in illicit drug samples (e.g. caffeine and sucrose) was not significant.

Rapid Micro-induction of Buprenorphine/Naloxone for Opioid Use Disorder in a Critically ill Intubated Patient: A Case Report.

BACKGROUND: Buprenorphine/naloxone has been shown to be an effective treatment of opioid use disorder. According to the Canadian National clinical practice guideline on the management of opioid use disorders, given the superior safety profile of buprenorphine/naloxone and its potential for flexible take-home dosing in comparison to other opioid agonist medication it is strongly recommended to initiate opioid agonist treatment with buprenorphine/naloxone as the preferred first-line treatment when possible. Due to its pharmacological properties induction can be challenging, requiring the cessation of all opioids for a certain amount of time to avoid the risk of precipitated withdrawal symptoms. For this reason, buprenorphine/naloxone is not initiated for the treatment of opioid use disorder in critically ill patients where continuous infusion of opioids are required for maintenance of sedation resulting in a missed opportunity for first line treatment of that patient's opioid use disorder. CASE SUMMARY: We present a case of a 29-year-old female with opioid use disorder admitted for infective endocarditis and septic shock requiring intubation for hypoxic respiratory failure secondary to bilateral lung septic emboli with a high opioid debt requiring higher than typical doses of fentanyl and dexmedetomidine infusions to maintain sedation with clinical objective sign of inadequate treatment of her pain and opioid withdrawal. She was successfully started on buprenorphine/naloxone using a rapid micro-induction technique that did not cause precipitated withdrawal or require cessation of her fentanyl infusion. CONCLUSION: This case illustrates a new method for starting buprenorphine/naloxone in a critically ill intubated patient, where buprenorphine/naloxone was never a consideration in this specific patient population. SCIENTIFIC SIGNIFICANCE: This method can be used to minimize barriers to opioid agonist therapy in intubated patients.

Rapid Induction of Buprenorphine/Naloxone for Chronic Pain Using a Microdosing Regimen: A Case Report.

Buprenorphine is an effective treatment for chronic pain and may reduce opioid-induced hyperalgesia. However, its pharmacological properties make its induction challenging, time-consuming, and can precipitate opioid withdrawal. We present the case of a 66-year-old woman with inadequately controlled postoperative pain despite escalating doses of oxycodone and methadone, who was successfully transitioned to buprenorphine/naloxone using a rapid microinduction technique without precipitating opioid withdrawal. Rapid induction provides an alternative method for transitioning patients from other opioids to buprenorphine/naloxone and facilitates transition of patients with chronic pain to buprenorphine therapy within a shorter window compared to currently existing protocols.
