Interaction entre Citalopram et Ziprasidone

…drugs, ziprasidone is contraindicated: • in patients with a known history of QT prolongation (including congenital long QT syndrome) • in patients with recent acute myocardial infarction • in patients with uncompensated heart failure Pharmacokinetic/pharmacodynamic studies between ziprasidone and other drugs that prolong the QT interval have not been performed.

An additive effect of ziprasidone and other drugs that prolong the QT interval cannot be excluded.

• Serotonin Syndrome : Increased risk when co-administered with other serotonergic agents, but also when taken alone.

QT Prolongation and Risk of Sudden Death Ziprasidone use should be avoided in combination with other drugs that are known to prolong the QTc interval [see Contraindications (4.1) and Drug Interactions (7.4) ].

If concomitant use of ziprasidone with other serotonergic drugs is clinically warranted, inform patients of the increased risk of serotonin syndrome and monitor for symptoms.

Avoid use of Citalopram Capsules in patients with congenital long QT syndrome, bradycardia, hypokalemia or hypomagnesemia, recent acute myocardial infarction, or uncompensated heart failure and patients taking other drugs that prolong the QTc interval.

Citalopram should also not be used in patients who are taking other drugs that prolong the QTc interval [see Drug Interactions (7)].

Such drugs include Class 1A (e.g., quinidine, procainamide) or Class III (e.g., amiodarone, sotalol) antiarrhythmic medications, antipsychotic medications (e.g., chlorpromazine, thioridazine), antibiotics (e.g., gatifloxacin, moxifloxacin), or any other class of medications known to prolong the QTc interval (e.g., pentamidine, levomethadyl acetate, methadone).

These include those patients with the cardiac conditions noted above, and those taking other drugs that may prolong the QTc interval.
