On Aug, 26, 2020. Methadone, a synthetic opioid for treatment of chronic pain and withdrawal from opioid dependence, has been linked to QT prolongation, potentially fatal torsades de pointes, and sudden cardiac death. This site needs JavaScript to work properly. Concomitant use of diazepam or other benzodiazepines in methadone maintenance treatment can increase the risk of sudden death. 2017 Dec;7(12):251-264. doi: 10.1177/2045125317721662.

COVID-19 is an emerging, rapidly evolving situation. Therefore, we determined the effects of methadone and diazepam singly and in combination on cardiac action potentials (APs) and on the major ion channels responsible for cardiac repolarization.

Please enable it to take advantage of the complete set of features! However, methadone is increasingly being used for the treatment of chronic pain because of its mechanism of action, high oral bioavailability, absence of active metabolites, prolonged analgesic effects, and relatively low cost.1, 2, 3 Reports of methadone-related cardiac adverse effects, including ventricular arrhythmias and deaths, have increased in recent years, … 1998;49:263-74. doi: 10.1146/annurev.med.49.1.263.Arch Toxicol. Methadone, a synthetic opioid for treatment of chronic pain and withdrawal from opioid dependence, has been linked to QT prolongation, potentially fatal torsades de pointes, and sudden cardiac death. Using patch clamp recording in human stem cell-derived cardiomyocytes and stably transfected mammalian cells, we found that methadone produced concentration-dependent AP prolongation and ion channel block at low micromolar concentrations: hERG (IC50 = 1.7 μM), hNav1.5 (11.2 μM tonic block; 5.5 μM phasic block), and hCav1.2 (26.7 μM tonic block; 7.7 μM phasic block). Concomitant use of diazepam or other benzodiazepines in methadone maintenance treatment can increase the risk of sudden death.
However, coadministration of 1-μM diazepam with methadone caused a statistically significant increase in AP duration and a 4-fold attenuation of hNav1.5 block (IC50 values were 44.2 μM and 26.6 μM, respectively, for tonic and phasic block), with no significant effect on methadone-induced block of hERG, hCav1.2, hKv4.3/hKChIP2.2, and hKvLQT1/hminK channels. 2011 Jul 1;91(1):53-61. doi: 10.1093/cvr/cvr044.
