    Plaquenil and citalopram qt prolongation


    The patient experienced a ventricular tachycardia leading to cardiac arrest and was found to have a prolonged QT interval. Although citalopram is eliminated more slowly in patients with mild to moderate renal impairment a dose adjustment is not necessary. However, no information is available on treatment of patients with severely reduced renal function and prescribers are advised to use caution.

    QTc prolongation was identified in 12 patients 16.4% among the entire study sample and in 7 patients 21.7% in the subgroup of patients ≥60 years old. The prevalence of QTc prolongation increased with citalopram dose in the entire study population P =.016. This trend was also observed in patients ≥60 years old but did not meet statistical significance. WebMD provides information about interactions between Sotalol Oral and qt-prolonging-agents-citalopram. Mar 10, 2016 In case of TdP arrhythmia QT interval prolongation can be used as a relatively safe indicator of PD drug interaction result, though a number of drug combinations possibly implicated in QT prolongation is practically infinite and it is infeasible to comprehensively assess all of them during the drug development process and clinical trials.

    QT prolongation is a measure of delayed ventricular repolarisation, which can cause Torsades de Pointes, ventricular tachycardia, and sudden death. In elderly patients, patients with reduced hepatic function, patients who are CYP2C19 poor metabolisers, and patients taking CYPC19 inhibitors (eg, cimetidine and omeprazole), the maximum dose should not exceed 20 mg a day because these factors lead to increased blood levels of citalopram.

    For citalopram doses of 40 mg/day, prolongation of the corrected QTc interval was estimated to be 12.6 ms. 5 For reference, increases in QTc to ≥ 500 ms or a drug -induced increase from baseline of ≥ 60 ms would represent significant changes in clinical trials.

Consult your healthcare professional before taking or discontinuing any drug or commencing any course of treatment. QT prolongation is an extended corrected QT QTc interval seen on an ECG at rest. 2 Because the QT interval is dependent on heart rate, the QTc interval is calculated to control for this factor. 2 QTc can be calculated by a variety of methods. 3 Definitions of QTc prolongation vary, but often this condition is described as a QTc interval of 440 ms. 2 Other definitions allow for a higher cutoff, such as 460 ms, in females. 3
