Key result
Drug-induced QT prolongation exhibits considerable inter-individual variability highlighting the relevance of personalized pharmacogenetics.
Why the study?
Many frequently used drugs prolong the QT interval and increase torsade de pointes risk, but considerable inter-individual variability in drug response necessitates evaluating individual risk from a pharmacogenetic standpoint.
Pharmacogenetic evaluation may help personalize risk assessment for drug-induced QT prolongation and torsade de pointes.
Long QT syndromes can be either acquired or congenital. Drugs are one of the many etiologies that may induce acquired long QT syndrome. In fact, many drugs frequently used in the clinical setting are a known risk factor for a prolonged QT interval, thus increasing the chances of developing torsade de pointes. The molecular mechanisms involved in the prolongation of the QT interval are common to most medications. However, there is considerable inter-individual variability in drug response, thus making the application of personalized medicine a relevant aspect in long QT syndrome, in order to evaluate the risk of every individual from a pharmacogenetic standpoint.

Baracaldo-Santamaría et al. (2021) conducted a review in Drug-Induced QT Interval Prolongation. Drugs inducing QT prolongation was evaluated. Drug-induced QT interval prolongation involves common molecular mechanisms but exhibits considerable inter-individual variability, highlighting the relevance of pharmacogenetics and personalized medicine.
