Interaction entre Ilopéridone et Propafénone

• Avoid use with other antiarrhythmic agents or drugs that prolong the QT interval.

It may also worsen premature ventricular contractions or supraventricular arrhythmias, and it may prolong the QT interval.

Use with Drugs that Prolong the QT Interval and Antiarrhythmic Agents The use of propafenone hydrochloride extended-release capsules in conjunction with other drugs that prolong the QT interval has not been extensively studied.

…FANAPT should be avoided in combination with other drugs that are known to prolong QTc including 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…

Table 7: Clinically Important Drug Interactions with FANAPT Strong CYP2D6 Inhibitors Clinical Impact Coadministration of fluoxetine with iloperidone increased exposure (area under curve, [AUC]) of iloperidone and its metabolite P88, by about 2- to 3- fold, and decreased the AUC of its metabolite P95 by one-half [see Clinical Pharmacology (12.3 , 12.5) ] .

Intervention Reduce the dose of FANAPT by one-half when administered with strong CYP2D6 inhibitors.

When a strong CYP2D6 inhibitor is withdrawn from the combination therapy, the iloperidone dose should be returned to the previous level [see Dosage and Administration (2.4) ] .

When the inhibitors of CYP2D6 and CYP3A4 are withdrawn from the combination therapy, the FANAPT dose should be returned to the previous level [see Dosage and Administration (2.4) ] .
