Title : Methadone versus buprenorphine/naloxone in opioid agonist therapy treatment retention


By the end of this presentation, participants will be able to describe the relative treatment retention rates for first episode opioid replacement treatment between methadone and buprenorphine/naloxone for patients receiving daily witnessed dispensed medications in naturalistic setting. Participants will also be able to list the benefits and risk of different medications used in opioid addictions.

This study is a longitudinal retrospective descriptive study analyzing secondary data from Canada on 1867 patients 18 years of age and older who started first episode opioid agonist therapy with methadone or buprenorphine/naloxone for opioid use disorder during a 4-year period.  Treatment episode was defined as date of initial opioid agonist prescription until there is a gap of greater than 6 days without receiving opioid agonist medication at a pharmacy.
