RESUMEN
Long-acting opioids are prescribed as part of treatment for opioid use disorders; methadone and buprenorphine are well researched and commonly prescribed for the treatment of opioid use disorder. Meta-analysis suggests that buprenorphine has a slightly poorer retention rate in treatment as compared to methadone. Benefits of buprenorphine/naloxone include greater ease in ceasing treatment and less use of illicit opioids while in treatment as compared to methadone. There are a number of qualitative and mixed-method studies that ask patients about their experiences of methadone maintenance and buprenorphine maintenance treatment. This research aimed to understand perspectives of receiving buprenorphine/naloxone for the treatment of opioid use disorder. A qualitative descriptive approach was used. Seven participants with a current diagnosis of opioid use disorder treated with buprenorphine/naloxone were interviewed. Thematic analysis extracted four themes: drivers for opioid substitution treatment change; readiness for buprenorphine/naloxone substitution treatment; absence of effect from buprenorphine/naloxone; and an increased sense of citizenship on buprenorphine/naloxone. This study identified a number of factors influencing participants' decision-making in transferring between methadone and buprenorphine/naloxone for the treatment of their opioid use disorder. Methadone was preferred by those seeking sedation and wishing to continue using other opioids, and buprenorphine/naloxone was most effective for participants no longer wishing to experience sedation and seeing opioid abstinence as an end point in their recovery. Changing treatment expectations are important to consider when determining medication selection and highlight the importance of quality information when determining the most suitable medication for the treatment of opioid use disorder.
