Bien que le développement de nouveaux médicaments intègre désormais la recherche d’un effet inhibiteur du courant potassique Ikr (canal potassique voltage- dépendant hERG [human Ether-à-go-go-Related Gene]) qui exerce une influence directe sur l’intervalle QT, il existe un nombre croissant de médicaments entraînant un risque connu de survenue de TdP (tableau 1) [1]. Ventricular depolarization, expressed as the QRS complex on an electrocardiogram (ECG), is the rapid movement of ions (sodium, potassium, and calcium) across the cellular membrane, creating electrical impulses that lead to ventricular contraction. Any patient on a QT prolonging drug who reports symptoms such as palpitations, light-headedness and dizziness should be referred for investigation and have their medication reviewed. Prolongation of the QT interval can lead to a life threatening ventricular arrhythmia known as torsades de pointes which can result in sudden cardiac death. The risk of torsades de pointes depends on patient factors and current medication. For people with LQTS there are specific medications that can have a serious effect by further prolonging the QT interval. We give a list of these medicines below. This list includes drugs that can stimulate and irritate the heart by causing adrenaline-like effects. A definitive QT/QTc study of healthy human subjects showed no effect on QTc interval after either a single low dose (1200 mg) or high dose (6000 mg) of oral gabapentin enacarbil (Fig. 1) [17••]. Case reports suggest the potential for these drugs to enhance QTc prolongation in patients receiving one or more known QTc–prolonging medications. For better measurement of the QT interval, some authorities have used a total of 6 leads, including 3 limb leads and 3 chest leads, and the median of the 6 individual leads as the QT value. CALCULATION OF THE CORRECTED QT. As repolarization is faster when the heart beats more rapidly, the QT interval should also be corrected for the heart rate. Der Einfluss von Arzneimitteln auf das QT-Intervall ist ein wichtiger Aspekt der Arzneimitteltherapiesicherheit, da eine Verlängerung des QT-Intervalls zu schwerwiegenden Herzrhythmusstörungen führen kann. Drugs associated with QT Prolongation, QTc prolongation including Antipsychotics, antiarrhythmics, antidepressants, and antihistamines Samtidig inntak av gabapentin og antacida minsker biotilgjengeligheten med inntil 24%. Gabapentin bør derfor tas tidligst 2 timer etter antacida. Det er sett respirasjonsdepresjon, sedasjon og død ved bruk av gabapentin samtidig med CNS-dempende legemidler (inkl. opioider). Risikoen er større hos svake, eldre, ved alvorlige underliggende 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 seen in KCNQ1, KCNH2 (hERG) and SCN5A ion channels. QT prolongation can remain asymptomatic or lead to torsades de pointes (TdP), a rare tachyarrhythmia which can be life-threatening or nearly fatal due to ventricular fibrillation and sudden cardiac death. Long QT syndrome (LQTS) is a cardiac conduction disorder characterized by prolongation and increased dispersion of ventricular repolarization, manifested by lengthening of the QT interval on the surface electrocardiography (ECG). A comprehensive list of conditions and drugs that may prolong the QT interval, and cause torsade de pointes (TdP) and long QT syndrome (LQTS) is presented below. 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. To support clinicians, who are likely to prescribe such medicines in their daily practice, we developed a simple algorithm to help guide clinical management in patients who are at risk of QT prolongation/TdP, those exposed to QT-prolonging medication or have QT prolongation. neurontin Ce médicament est un antiépileptique donné sur ordonnance. Il se présente sous la forme de gélules blanches à 100 mg en boîte de 90, de gélules jaunes à 300 mg en boîte de 90, de gélules orange à 400 mg en boîte de 90, de comprimés blancs à 600 mg en boîte de 90 et de comprimés blancs à 800 mg en boîte de 90. Neurontin® gabapentin anbefalt til behandling av nevropatisk smerte 1. Neurontin er anbefalt som et av førstevalgspreparatene i behandling av nevropatisk smerte, både i nasjonale retningslinjer for smertelindring 1 og internasjonale guidelines NeuPSIG 2 og EFNS 3 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). 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 Drugs-Induced QT Interval Prolongation. Κατά τις τελευταίες δυο δεκαετίες, το έντονο ερευνητικό ενδιαφέρον έχει βελτιώσει τις γνώσεις μας όσον αφορά τους μηχανισμούς και κινδύνους της παρατάσεως του QT διαστήματος από φάρμακα 1.
