چکیده

BACKGROUND This study evaluated the effects of atypical antipsychotic drugs and selective serotonin reuptake inhibitors (SSRIs) on the corrected QT (QTc) interval using a large database obtained from clinical settings. Additionally, the effects of factors including age on QTc intervals were estimated. METHODS Using an open-access QT database (ECG-ViEW), QTc-lengthening effects of 14 selected atypical antipsychotics and SSRIs were compared to those of a positive control drug, cilostazol, and a negative control drug, diazepam. We also evaluated effects of age, sexgender, and select electrolyte levels on observed QTc intervals. RESULTS The frequency of QTc prolongation with the pooled data of the 14 study drugs was lower than that with cilostazol (age-adjusted odds ratio (OR) = 0.43, 95% confidence interval (CI) = 0.27-0.69), but no significant difference was found relative to when compared with that with diazepam (age-adjusted OR = 0.89, 95% CI = 0.55-1.47). Furthermore, administration of the 14 study drugs significantly increased the QTc interval by 2.89 ms after each 10-year age increment (p-value < 0.0001). CONCLUSIONS This study suggests that atypical antipsychotic drugs and SSRIs are less likely to be associated with QTc prolongation in clinical settings. In addition, age showed a significant association with the QTc interval. Further studies with well-characterized cohorts are warranted.

QTc prolongation, torsades de pointes, and psychotropic medications.

BACKGROUND Prolongation of the corrected QT (QTc) interval is a key issue for patients who receive psychotropic medications. Such patients may have baseline clinical risk factors for QTc prolongation, and many psychotropic medications may further prolong this interval. This has great clinical relevance, as QTc prolongation is linked with dangerous arrhythmias, especially torsades de pointes (Td...

Serotonin (5-hydroxytryptamine)(1B/1D) agonists can vasoconstrict coronary and cerebral arteries. Chest, jaw, and arm discomfort, so-called "triptan sensations," are often felt to be noncardiac. In Part 1 of this review, the relationship of triptans, coronary artery narrowing, and spasm was discussed, along with a case of a 53-year-old woman without cardiac risk factors who developed polymorphi...

Antenatal use of selective serotonin-reuptake inhibitors and QT interval prolongation in newborns.

OBJECTIVES Prolongation of the QT interval is a risk factor for sudden death. Selective serotonin-reuptake inhibitor antidepressants can prolong the QT interval and are widely used by pregnant women. Whether antenatal exposure to selective serotonin-reuptake inhibitor causes QT prolongation in offspring is unknown. The aim of this study was to determine the effect of maternal use of selective s...
