Methadone Maintenance and QT-Interval: Prevalence and Risk Factors—Is It Effective to Switch Therapy to Levomethadone?

Biomedicines, 2023
Methadone is a chiral synthetic opioid primarily used to treat heroin and prescription-opioid addiction: the (R)-enantiomer (Levomethadone) activates the µ-opioid receptor more potently than the (S)-enantiomer, which is a more potent blocker of the hERG ...

Determinants of severe QTc prolongation in a real-world gerontopsychiatric setting

Frontiers in Psychiatry, 2023
IntroductionQTc prolongation carries the risk of ventricular tachyarrhythmia (Torsades de Pointes) and sudden cardiac death. Psychotropic drugs can affect ventricular repolarization and thus prolong the QTc interval.

Multichannel modulation of depolarizing and repolarizing ion currents increases the positive rate‐dependent action potential prolongation

Physiological Reports, 2023
Prolongation of the action potential duration (APD) could prevent reentrant arrhythmias if prolongation occurs at the fast excitation rates of tachycardia with minimal prolongation at slow excitation rates (i.e., if prolongation is positive rate ...
