Article Abstract Objective: To evaluate the association between selective serotonin reuptake inhibitors (SSRIs) and corrected QT interval (QTc) prolongation via meta-analysis of prospective studies. The observed QT (QT o ) interval can be corrected (QT c ) for heart rate by using the following formula where RR is the interval in seconds between two successive R waves . A diurnal variation of the QT interval associated with the variations in sympathetic tone has also been described. Or, stop the first agent and start a dose of the new If the patient was taking a high dose of the first agent, consider tapering to a lower dose before starting the new agent. Stop SSRI. QTc Prolongation by Psychotropic Drugs and the Risk of ... The antidepressants such as citalopram, escitalopram, venlafaxine, desvenlafaxine, sertraline clomipramine and bupropion are among the drugs which are known for prolongation of QT interval. 5. As psychotropic drugs prolong cardiac repolarization, they increase the risk of Torsades de Pointes (TdP). Cardiovascular adverse effects associated with clozapine—including QTc prolongation—are dose-dependent. The QTc interval is reported on the ECG printout. During post-marketing use of Sertraline, cases of QTc prolongation and Torsade de Pointes (TdP) have been reported. relevant for QT interval measurement and heart-rate correction. Sertraline should be used with caution in patients with risk factors for QTc prolongation including congenital long QT syndrome, age >65 years, female sex, structural heart disease/LV dysfunction, medical conditions such as renal or hepatic disease, use of medicines that inhibit the metabolism of Zoloft is known to prolong the QT interval. Once corrected it is expressed as the QTc interval. the QT interval varies from lead to lead. To a lesser extent, the concern has also been raised for fluoxetine. of QTc prolongation. However, no QTc value has been established for cardiac arrhythmia. What is considered to be a prolonged QT interval? Biochemistry results (within last two weeks): sodium, potassium, urea, creatinine, eGFR [+ magnesium level if potassium (< 3.5mm/L]; FBC results 8. Fluoxetine, escitalopram, and sertraline used in post-acute coronary syndrome patients did not demonstrate risk of QTc prolongation. It is therefore advised that an SSRI should be gradually tapered over a period of several weeks or months, according to the person's needs. Escitalopram and sertraline lengthen the QT interval by 7 msec and 3 msec, respectively. Older Adults >65 years Recommend monitoring for antidepressant - induced hyponatraemia. Sertraline. The frequency of QTc prolongation (more than 456 ms) in psychiatric patients is estimated to be 8%. Pharmacogenomics: Sertraline is metabolised primarily by CYP2C19 isoenzyme. In clinical practice, if the QT interval appears to be greater than half of the RR interval (and heart rate is close to 60 bpm) an observer can easily and rapidly identify QTc prolongation. There is little compelling evidence that recommended doses of other SSRIs prolong the QT interval. Many drugs can cause QT interval prolongation including azithromycin, fluoroquinlones, fluconazole, sertraline, citalopram, escitalopram, risperidone and domperidone. Normal QTc intervals are typically <450 ms for men and <460 ms for women. •Bupropion -Associated with QTc prolongation in overdose; possibly confounded by tachycardia •Trazodone -Associated with mild QTc prolongation in overdose •Mirtazapine Introduction. We did not find a TQ study for sertraline. Start new SSRI at a low dose (e.g., citalopram, escitalopram, or paroxetine10 mg/day; sertraline 25 mg/day; or fluoxetine 20 mg every-other-day). I think uncorrected QT of 448 msec is slightly long at heart rate 71. QTc is the QT interval corrected for heart rate. QT (QTc) Prolongation and Monitoring Primer QT (QTc) Prolongation is associated with many psychotropic medications (especially antipsychotics) and some are linked to serious ventricular arrhythmias (e.g. tion antidepressants by re-analysing short-term ran-domised controlled trial data in a multiple-treatment meta-analysis. However, 5 months later, a repeat ECG showed a QTc of 507 ms, and thus sertraline was . 2 qtc can be calculated by a variety of methods. Design A cross sectional study using electrocardiographic, prescribing, and clinical data from electronic health records to explore the relation between antidepressant dose and QTc. 10 Preclinical data, however, suggest a potential dose-dependent risk of QT interval prolongation after sertraline administration. Tricyclic antidepressants (TCAs) were associated with a significantly greater QTc increase than SSRIs (TCA prolongation, 7.05 milliseconds; 95% CI, 3.84-10.27 greater than SSRIs; P < .001). SNRIs: Avoid Venlafaxine b/c it's the worst, Desvenlafaxine is probably safe, Duloxetine doesn't have enough data but may shorten QTc, Milnacipran caused minor QTc prolongation but likely d/t changes in heart rate. QTc Prolongation and Psychotropics- Management of Prolonged QTc interval in Psychiatry. In regards to QT dispersion. Age over 65 years, tricyclic antidepressants (TCA), thioridazine, droperidol, olanzapine, and . Once corrected it is expressed as the QTc interval. o SSRIs are well studied and considered safe in patients with heart disease. 5 (Tartrazine): Contains FD&C QTc prolongation, however, has been reported with low-dose methadone therapy (14 mg/day) when hepatic metabolism of methadone is affected by other drugs [14]. Sertraline HCl Capsules, in patients with untreated anatomically narrow angles (5.7) • QTc Prolongation: Sertraline HCl Capsules should be used with caution in patients with risk factors for QTc prolongation (5.10) • Allergic Reactions to FD&C Yellow No. 7 provided an encyclopedic review of nonantiarrhythmic drugs associated with QT interval prolongation and torsade de pointes. Objective To quantify the impact of citalopram and other selective serotonin reuptake inhibitors on corrected QT interval (QTc), a marker of risk for ventricular arrhythmia, in a large and diverse clinical population. The QT interval, most often reported as the cor-rected (for heart rate) QT interval or QTc, is an electrocardiographic measure of ventricular repo-larization and depolarization. The prevalence of CYP2C19 allele varies among different ethnic backgrounds (e.g. Fluoxetine, escitalopram, and sertraline used in post-acute coronary syndrome patients did not demonstrate risk of QTc prolongation. Clinical aspects of ventricular arrhythmias associated with QT prolongation. prescribe in patients with known QTc prolongation, congenital long QT syndrome or prolong QTc. Avoid or Use Alternate Drug. Use of this intersection to define the end of the T-wave is a reliable and well-accepted method for QT interval measurement. 1 A normal QT inter-val is less than 450 ms in men and 460 ms in women.2 A number of drugs have been implicated in prolongation of the QT interval, including anti- Selective serotonin reuptake inhibitors (SSRIs) are the most common antidepressants used in first-world countries and are generally well tolerated. however, increases, such as the reported average 18.5-ms increase associated with 60 mg of citalopram, may not be clinically significant, because qt prolongation indicates only the potential for an event to occur. Meta-analysis of selective serotonin reuptake inhibitor-associated QTc prolongation SSRIs were associated with a modest but statistically significant increase in the QTc interval, although to a lesser extent than TCAs; this finding was not limited to any single study. Unfortunately, many psychiatric medications such as antidepressants and antipsychotics have a risk of prolonging QT. A vast body of evidence exists concerning the risks of QT interval prolongation associated with these agents and healthcare providers should critically evaluate the potential for QT prolongation when selecting antidepressant agents. Antidepressants are widely used medications for a range of medical conditions such as mood disorders and chronic pain in older adults. Citalopram was associated with more QTc prolongation than most other SSRIs. Summary: QT prolongation from psychiatric medications leading to potentially fatal cardiac arrhythmias (such as Torsades de Point) is an uncommon but serious complication. Sign in Register. The QT interval is dependent on heart rate, age and gender. 7. Large, prospective, population-based studies have linked QTc prolongation with increased mortality, FIGURE 1. Ehret and colleagues also reported that QTc pro-longation occurred in patients taking methadone, 30 mg/day [13].
