Fosamprenavir calcium/ritonavir: ↔ Amprenavir ↔ Esomeprazole Sedative/hypnotics: Midazolam, triazolam ↑Midazolam ↑Triazolam Coadministration is contraindicated due to potential for serious and/or life-threatening reactions such as prolonged or increased sedation or respiratory depression [see Contraindications (4)].

Antipsychotics: Lurasidone Pimozide Quetiapine ↑Lurasidone ↑Pimozide ↑Quetiapine Fosamprenavir calcium: If coadministration is necessary, reduce the lurasidone dose.

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When the CYP3A4 inhibitor is withdrawn from the combination therapy, the FANAPT dose should be returned to the previous level [see Dosage and Administration (2.4) ] .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