What drugs can cause long QT syndrome?
The most potent QT-prolonging medications are antiarrhythmic agents, particularly amiodarone, dofetilide, quinidine, and sotalol, with quinidine possibly having the most torsadogenic potential.
Does omeprazole prolong QTc?
The most commonly used QT prolonging drugs in medical wards were, omeprazole (25.9%), furosemide (13.8%), esomeprazole (13.8%), metronidazole (11.1%), azithromycin (4.7%), clarithromycin (4.5%), ciprofloxacin (4.1%), domperidone (3.1%), ondansetron (2.5%), moxifloxacin (2.1%), fluconazole (2.1%), metoclopramide (1.4%).
Which antibiotics prolong QTc?
Ketoconazole, itraconazole, fluconazole, and voriconazole have been shown to prolong the QT interval and to be associated with TdP, with the majority of reports of TdP stemming from drug interactions and involving ketoconazole and itraconazole [74–88]. Akin to the macrolides, the azoles are “dual-risk” agents.
What can prolong QT interval?
Using medications known to cause prolonged QT intervals. Being female and on heart medication. Excessive vomiting or diarrhea, which causes electrolyte imbalances. Eating disorders, such as anorexia nervosa, which cause electrolyte imbalances.
Does Tramadol prolong QTc?
Conclusion: Tramadol produces QTc interval prolongation in good correlation with plasma drug concentrations; renal failure is a risk factor for higher concentration and QT prolongation by tramadol.
Can pantoprazole prolong QT?
PPIs do not directly cause prolongation of the QT interval, but they have been associated with hypomagnesemia, which is often accompanied by hypocalcemia and hypokalemia and can result in cardiac repolarization disturbances such as QT interval prolongation.
Does Pepcid cause QT prolongation?
Famotidine does not induce long QT syndrome.
Do all fluoroquinolones prolong QT?
By doing so, fluoroquinolones usually, but not always, prolong the QT interval, a process that even if subdued may lead to the occurrence of arrhythmia. In addition, they have the potential to interact with other drugs that prolong the QTc interval.
Which Diuretics cause QT prolongation?
Thiazide diuretics, commonly used antihypertensives, may cause QT interval (QT) prolongation, a risk factor for highly fatal and difficult to predict ventricular arrhythmias.
Does low potassium cause long QT?
Hypokalemia is another common risk factor in drug-induced LQTS. Low extracellular potassium paradoxically reduces IKr by enhanced inactivation [42] or exaggerated competitive block by sodium [43]. As a result, hypokalemia prolongs the QT interval.
Does metoprolol help prolonged QT?
Conclusions: Propranolol has a significantly better QTc shortening effect compared to metoprolol and nadolol, especially in patients with prolonged QTc. Propranolol and nadolol are equally effective, whereas symptomatic patients started on metoprolol are at a significantly higher risk for BCEs.
Does ibuprofen prolong QTc?
The duration of the QRS complex wave (QRS duration) in ECG was prolonged. Although the heart rate was depressed by ibuprofen, the corrected QT interval duration (QTc) decreased.
