FANAPT vs LUMATEPERONE TOSYLATE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
FANAPT (iloperidone) is an atypical antipsychotic that exhibits high affinity for serotonin 5-HT2A and dopamine D2 receptors, with additional antagonism at alpha1-adrenergic, alpha2-adrenergic, and histamine H1 receptors. The therapeutic efficacy is primarily attributed to combined 5-HT2A and D2 receptor antagonism.
Lumateperone tosylate is an atypical antipsychotic with a unique mechanism of action involving antagonism of serotonin 5-HT2A receptors, partial agonism of serotonin 5-HT1A receptors, and antagonism of dopamine D2 receptors; it also modulates glutamate via phosphorylation of GluN2B subunits and inhibits serotonin reuptake.
12-24 mg orally once daily, titrated from 1 mg twice daily on day 1, 2 mg twice daily on day 2, 4 mg twice daily on day 3, 6 mg twice daily on day 4, 8 mg twice daily on day 5, then 10 mg twice daily on day 6 and 7, followed by 12 mg once daily on day 8. Maximum dose: 24 mg/day.

Terminal elimination half-life is approximately 26 hours (range 22-30 hours) for the sum of parent drug and active metabolites (P95, P88, and P86); steady-state achieved within 4-5 days.
Terminal elimination half-life is approximately 24-29 hours, allowing once-daily dosing. Steady-state reached in about 5 days.
Renal (approximately 80% as metabolites, <1% as parent drug) and fecal (approximately 20% as metabolites).
Approximately 60% excreted in urine as metabolites (unchanged drug negligible) and 30% in feces via biliary elimination.
