Sudden death during methadone replacement therapy – case report and literature review

Summary/Abstract: Methadone is a diphenylpropylamine derivative that binds to opioid receptors and has been used in drug abstinence and substitution treatment programs. The aim of the study is to describe a case of sudden death of a prisoner during methadone substitution therapy from the authors’ medico-legal consulting practice and to review the literature. A 41-year-old male with a long history of abuse of psychoactive substances, especially heroin, serving a prison sentence, after consultation in the addiction treatment clinic, started methadone substitution therapy. In the following days he took two doses of the drug (50 mg each). The prisoner was pronounced dead during the night. Blood toxicology tests showed the presence of methadone at the therapeutic concentration of 816 ng/ml. Currently, it is believed that even the therapeutic concentration of methadone increases the risk of sudden cardiac death, especially in predisposed patients (e.g. with structural pathologies of the myocardium, cardiac arrhythmias, hypokalemia, and liver failure).
