Long-Term Follow-Up of Orally Administered Diacetylmorphine Substitution TreatmentFrick, Ulrich, Rehm, Jürgen, Zullino, Daniele, Fernando, Manrique, Wiesbeck, Gerhard, Ammann, Jeannine, Uchtenhagen, Ambros 11 February 2014 (has links) (PDF)
Background: To assess the long-term course of the feasibility and safety of orally administered heroin [diacetylmorphine (DAM)] tablets in substitution treatment of severely addicted opioid users.
Design: Open-label, prospective cohort study with 2 non-randomly assigned treatment arms: DAM tablets only (n = 128) or DAM tablets combined with injected DAM and/or other opioids (n = 237). The average duration of the observation period was 62 months. Study endpoints were the time to discharge from treatment and the number of serious adverse events.
Results: Both patient groups had a higher than 70% retention rate after the first 48 months of treatment, with similar long-term retention rates (after 8 years both groups had retention over 50%). The physician-verified rate of serious adverse events was 0.01 events per application year among the exclusively oral substitution group (intention-to-treat analysis) during the last year of observation, and 0.005 events per application year in the other group.
Conclusions: Because of their feasibility and safety over years, DAM tablets may be a valuable long-term therapeutic alternative. / Dieser Beitrag ist mit Zustimmung des Rechteinhabers aufgrund einer (DFG-geförderten) Allianz- bzw. Nationallizenz frei zugänglich.

Six-Year Outcome of Opioid Maintenance Treatment in Heroin-Dependent Patients: Results from a Naturalistic Study in a Nationally Representative SampleSoyka, Michael, Strehle, Jens, Rehm, Jürgen, Bühringer, Gerhard, Wittchen, Hans-Ulrich 04 August 2020 (has links)
Background: In many countries, the opioid agonists, buprenorphine and methadone, are licensed for maintenance treatment of opioid dependence. Many short-term studies have been performed, but little is known about long-term effects. Therefore, this study described over 6 years (1) mortality, retention and abstinence rates and (2) changes in concomitant drug use and somatic and mental health. Methods: A prevalence sample of n = 2,694 maintenance patients, recruited from a nationally representative sample of n = 223 substitution doctors, was evaluated in a 6-year prospectivelongitudinal naturalistic study. At 72 months, n = 1,624 patients were assessed for outcome; 1,147 had full outcome data, 346 primary outcome data and 131 had died; 660 individuals were lost to follow-up. Results: The 6-year retention rate was 76.6%; the average mortality rate was 1.1%. During follow-up, 9.4% of patients became “abstinent” and 1.9% were referred for drug-free addiction treatment. Concomitant drug use decreased and somatic health status and social parameters improved. Conclusions: The study provides further evidence for the efficacy and safety of maintenance treatment with opioid agonists. In the long term, the number of opioid-free patients is low and most patients are more or less continuously under opioid maintenance therapy. Further implications are discussed.
