New generation antipsychotic drugs and QTc interval prolongation. Among antidepressant medications, citalopram does appear to prolong the QT interval more than other selective serotonin reuptake inhibitors, though the clinical significance of this prolongation remains unclear. Although escitalopram does not increase the QT interval when compared to citalopram but caution with its use is recommended. Only widespread use will prove if ziprasidone is entirely safe. There is a link between antipsychotic medications and prolongation of QTc interval, which is associated with an increased risk of torsade de po …
In the past decade, the effects of antidepressants on the QT interval and the subsequent risk of cardiac arrhythmias have become a notable concern. Many antipsychotic drugs cause QT prolongation, although the effect differs based on the particular drug. Escitalopram appears to prolong the QT interval to a lesser extent. Beach and colleagues 2 emphasize that SSRIs, including fluoxetine and paroxetine, are not statistically significantly associated with QT prolongation, as indicated by comprehensive, prospective studies regarding the corrected QT (QTc) interval. Elsevier Science Gill SS, Bronskill SE, Normand SL, et al. Our results suggest that second-generation antipsychotic drugs are generally less likely than first-generation antipsychotic drugs to produce QTc interval prolongation, which may be of use in clinical decision making concerning the choice of antipsychotic medication.

Ziprasidone does prolong the QT interval, but there is no evidence to suggest that this leads to torsade de pointes or sudden death. CNS Drugs. However, the Using logistic regression analysis to calculate the adjusted relative risk (RR), we found that chlorpromazine (RR for 100 mg=1.37, 95% confidence interval (CI)=1.14 to 1.64; p<.005), intravenous haloperidol (RR for 2 mg=1.29, 95% CI=1.18 to 1.43; p<.001), and sultopride (RR for 200 mg=1.45, 95% CI=1.28 to 1.63; p<.001) were associated with an increased risk of QTc prolongation. Case reports of QT prolongation have been published with all of the SSRIs, with the exception of paroxetine, but many of these events were in the context of an overdose, inherent risk factors, and concomitant use of other medications known to increase the QT interval, which makes it difficult to draw conclusions.TCAs and SNRIs have also been shown to prolong the QT interval to varying degrees. Therefore, clinical judgment and risks versus benefits need to be considered when prescribing antidepressants that may affect the QT interval.When a patient is assessed for antidepressant therapy, providers should keep the risk factors for QT prolongation in mind (QT prolongation risk varies with each antidepressant, and specific medications should be chosen with consideration of these differences. Moreover, the association between citalopram and ventricular arrhythmias and mortality has not been verified in studies of citalopram doses greater than 40 mg. Haloperidol carries a risk for QT prolongation, but the assertion that intravenous haloperidol is inherently riskier may be confounded … It prolongs the QT interval, blocks the I Kr channel , and ...
