ILOPERIDONE vs LUMATEPERONE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Iloperidone is an atypical antipsychotic with high affinity for serotonin 5-HT2A and dopamine D2 receptors; also moderate affinity for D3, D4, 5-HT6, 5-HT7, and α1-adrenergic receptors; low affinity for H1, 5-HT1A, and α2-adrenergic receptors; no affinity for M1 muscarinic receptors.
Lumateperone is an atypical antipsychotic with a unique mechanism of action: it acts as a 5-HT2A receptor antagonist, a dopamine D2 receptor antagonist, and a serotonin reuptake inhibitor. It also modulates glutamate via enhanced AMPA and NMDA receptor activity.
1-2 mg orally twice daily; target dose 6-12 mg/day; maximum 12 mg/day
42 mg orally once daily, taken with food and at least 240 mL of water, with a titration schedule: 42 mg daily for 7 days, then 21 mg twice daily thereafter.

Clinical Note
moderateIloperidone + Levofloxacin
"Iloperidone may increase the QTc-prolonging activities of Levofloxacin."
Clinical Note
moderateIloperidone + Norfloxacin
"Iloperidone may increase the QTc-prolonging activities of Norfloxacin."
Clinical Note
moderateIloperidone + Gemifloxacin
"Iloperidone may increase the QTc-prolonging activities of Gemifloxacin."
Clinical Note
moderateIloperidone + Haloperidol
"The metabolism of Haloperidol can be decreased when combined with Iloperidone."
Terminal elimination half-life 18 hours in extensive CYP2D6 metabolizers, 33 hours in poor metabolizers; clinical context: steady-state reached in ~5-7 days.
Terminal elimination half-life is approximately 13 hours in the plasma, supporting once-daily dosing. Steady state is reached within 5–7 days.
Primarily hepatic metabolism via CYP3A4 and CYP2D6; approximately 7% excreted unchanged in urine and 18% in feces; total renal elimination of metabolites ~25%, fecal ~60%.
Approximately 80% of the dose is excreted in feces (as unchanged drug and metabolites) and about 11% in urine. Less than 1% is excreted as unchanged lumateperone in urine.
