İloperidon ve Perampanel etkileşimi

The dose of FANAPT should be reduced in patients co-administered a strong CYP2D6 or CYP3A4 inhibitor.

Strong CYP3A4 Inhibitors Clinical Impact Co-administration of ketoconazole with iloperidone, increased the AUC of iloperidone and its metabolites P88 and P95 by 57%, 55%, and 35%, respectively [see Clinical Pharmacology (12.3) ] .

Intervention Reduce the dose of FANAPT by one-half when administered with strong CYP3A4 inhibitors.

When the CYP3A4 inhibitor is withdrawn from the combination therapy, the FANAPT dose should be returned to the previous level [see Dosage and Administration (2.4) ] .

Concomitant use of Strong CYP2D6 and Strong CYP3A4 Inhibitors Clinical Impact Coadministration of iloperidone with paroxetine and ketoconazole resulted in a 1.4- fold increase in steady-state concentrations of iloperidone and its metabolite P88 and a 1.4- fold decrease in the P95 in the presence of paroxetine [see Clinical Pharmacology (12.3) ] .

Patients should be carefully observed for signs of central nervous system (CNS) depression, such as somnolence and sedation, when FYCOMPA is used with other drugs with sedative properties because of potential additive effects.

Alcohol and Other CNS Depressants The concomitant use of FYCOMPA and CNS depressants including alcohol may increase CNS depression.

These effects may also be seen when FYCOMPA is used in combination with other CNS depressants.

Patients should limit activity until they have experience with concomitant use of CNS depressants (e.g., benzodiazepines, narcotics, barbiturates, sedating antihistamines).
