Sudden unexpected death in epilepsy (SUDEP) is the most common epilepsy-related cause of death. VPA Valproic acid 100 PEDIATRIC NEUROLOGY Vol. QTc prolongation and valproate toxicity. 2. traditional antiepileptic drugs such as primidone and magnesium are known to shorten the QT interval [23,24]; however, the mechanism is unclear. Clipboard, Search History, and several other advanced features are temporarily unavailable. 2019 Feb;42(2):235-245. doi: 10.1007/s40264-018-0773-9. While the precise pathophysiological mechanisms underlying SUDEP are still uncertain, impaired cardiac function including seizure-induced arrhythmias has received increased attention. Linde M, Mulleners WM, Chronicle EP, McCrory DC. In addition, protein-binding competition can potentially cause increased serum levels of medications that prolong QTCwhen combined with seemingly benign medications that are highly protein-bound (e.g., aspirin, valproic acid [Depakene], herbal preparations). Please enable it to take advantage of the complete set of features! While the preponderance of clinical data would suggest that use of most antiepileptic drugs does not pose excessive additional risk of QT prolongation, available data also do not provide sufficient evidence that these drugs are entirely free of risk in all patients. Quetiapine is a second-generation antipsychotic widely used for various psychotic and mood disorders.

In particular, the potential for these medications, either alone or in combination, to prolong the QT interval should be considered. In July 2011, the US Food and Drug Administration (FDA) directed AstraZeneca to add a warning to the quetiapine (Seroquel, AstraZeneca, Wilmington, USA) labeling about QT interval prolongation and the potential to induce torsade de pointes (TdP). While the preponderance of clinical data would suggest that use of most antiepileptic drugs does not pose excessive additional risk of QT prolongation, available data also do not provide sufficient evidence that these drugs are entirely free of risk in all patients. 2017 Sep;53(3):333-338. doi: 10.1016/j.jemermed.2016.07.017.Drug Saf.
