Antiarrhythmics, beta-blockers and some antidepressants are known to interact badly with it. Drugs which people with Long QT Syndrome should avoid; Below is a list of the drugs that people with Long QT Syndrome should avoid. A similar list can also be found by clicking here. Long qt syndrome is reported as a side effect among people who take Gabapentin (gabapentin), especially for people who are female, 60+ old, also take Aspirin, and have High blood pressure. The phase IV clinical study analyzes which people have Long qt syndrome when taking Gabapentin. A QT-concentration relationship was reported with moxifloxacin. Gabapentin exposures were dose-proportional with gabapentin enacarbil doses of 1200 and 6000 mg. The most commonly reported adverse events with gabapentin enacarbil 6000 mg were dizziness and somnolence (60.0% and 54.0%, respectively). Definitions for QT prolongation vary in the literature, but for men QTc >440 msec and for women QTc >470 msec are commonly used. The risk of TdP increases with increasing QTc, for every 10 msec increase, there is a ~5-7% increase in the risk of arrhythmic events. When QTc is greater than 500 msec for both men and women and/or an increase of >60 msec from baseline, risks are higher, and urgent Recently there have been warnings relating to drug-induced QT prolongation for three commonly used drugs – citalopram, domperidone and ondansetron.1,2,3 Extra vigilance is required by healthcare professionals to be alert to the risk of drug induced QT prolongation and drug interactions. The degree of QT prolongation is correlated to the level of risk, with severe prolongations being associated with much higher risk. The most common etiology is acquired prolongation due to medication use, followed by electrolyte abnormalities. With regards to drugs, the risk of QT prolongation and TdP varies markedly across the list but tends to be rather similar within a drug class. While the risk of TdP is well-defined for many of these agents, many are classified as QT-prolonging solely based on their drug class or presumed pharmacodynamic effects. Drugs associated with QT Prolongation, QTc prolongation including Antipsychotics, antiarrhythmics, antidepressants, and antihistamines Considering that not all agents that prolong the QT interval increase TDR, drugs can be distinguished into the following groups depending on their simultaneous effects on the QT corrected using the Bazzet’s formula (QTc) interval and on TDR [20]: (1) drugs inducing both QTc prolongation and increased TDR, characterized by a high torsadogenic Objective As part of the overall safety evaluation of gabapentin enacarbil, the present definitive QT/QTc study was conducted to assess the effects of gabapentin enacarbil on cardiac repolarization in accordance with the International Conference on Harmonization E14 guidance. Prolongation of the QT interval on the ECG is also associated with arrhythmia risk and sudden cardiac death. Congenital long QT syndrome (LQTS) comprises a group of arrhythmia disorders, arising from cardiac channelopathies in both sodium and potassium channels. Long QT syndrome affects about 1 in 2500 individuals and is associated with syncope and sudden cardiac death. In LQTS, mutations are Prolongation of the QT interval above 470 ms for men and 480 ms for women should be regarded as abnormal [4]. Several risk factors for QT prolongation have been identified, including female sex, advanced age, drug-drug interactions, genetic predisposition, hypokalemia, hypomagnesemia, heart failure, and bradycardia [5, 6]. Christoph Klivinyi and Helmar Bornemann-Cimenti Long QT syndrome is a cardiac repolarization disorder and is associated with an increased risk of torsades de pointes. The acquired form is most often attributable to administration of specific medications and/or electrolyte imbalance. This review provides insights into the risk for QT prolongation associated with drugs frequently used in the Mood stabilizers Among the mood stabilizers, lithium [22] has a moderate risk of QTc prolongation while the antiepileptics used for this purpose such as carbamazepine, oxcarbazepine, topiramate, valproate, [26] pregabalin, gabapentin, [27] and lamotrigine [28] are reported to be safe with a low risk of QTc prolongation. Anxiolytic drugs and Some psychotropic medications have been associated with prolongation of the QT interval and QT prolongation, especially in those with medical illness, and are linked to lethal ventricular arrhythmias, such as Torsades de Pointes (TdP). In 2013, we published a review of QT prolongation, TdP, and psychotropic medications. The length of the QT interval represents the time required for ventricular depolarization and repolarization. Prolongation of ventricular repolarization can result in fatal ventricular arrhythmias [3]. Faster heart rates can shorten the QT interval [4], so it is often adjusted for rate and reported as the heart rate corrected (QTc) interval. Many drug therapies are associated with prolongation of the QT interval. This may increase the risk of Torsades de Pointes (TdP), a potentially life-threatening cardiac arrhythmia. As the QT interval varies with a change in heart rate, various formulae can adjust for this, producing a 'corrected QT' Pregabalin use has been associated with QTc prolongation in patients taking other QTc–prolonging agents, although the relative contributions of pregabalin to QTc prolongation may be minimal. Pregabalin and gabapentin have been associated with a dose-related increased risk of atrial fibrillation. Although QT prolongation has been linked to the use of certain drugs, it remains difficult to predict the relative risk associated with their administration. Pharmacists can make recommendations to clinicians to help promote safer prescribing practices when selecting QT-prolonging drugs. The unexpected and catastrophic cardiovascular effects of psychotropic drugs are well described albeit uncommon. The list of drugs which have been associated with prolonging QT interval and hence potentially causing Torsades de pointes is
