The QTdrugs List includes three distinct risk categories for Torsades de Pointes (TdP) and QT prolongation but not all drugs in the List should be considered “QT prolonging”. Because of the inherent complexity of drug-induced QT prolongation and the ensuing risk of developing TdP, AZCERT has sub-divided the QTdrugs List into three categories of risk of causing TdP.1 We want to remind those who wish to use the QTdrugs List in clinical decision making of the differences between these categories and caution that the QTdrugs List should not simply be thought of as a list of “QT-prolonging drugs”… it is not.

Deutetrabenazine (used to treat tardive dyskinesia) and Dexmedetomidine (a sedative) were removed from the  Possible Risk of TdP category and are no longer on the QTdrugs list. Our analysis of new evidence did not support their continued placement on the list.  As demonstrated by these revisions, the QTdrugs list is dynamic and can change frequently.

New evidence for memantine and benperidol (including a thorough QT study, review of case reports, and drug label changes) does not indicate that memantine or benperidol are associated with QT prolongation under normal conditions of use. Therefore these two drugs have been removed from the Possible Risk of Torsades de pointes (TdP) category.  Also, diltiazem has been added to the Conditional Risk of TdP category.
