Abstract
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.
