CAPLYTA vs ZYPREXA RELPREVV
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
CAPLYTA (lumateperone) is a second-generation antipsychotic with a unique mechanism of action. It acts as a serotonin 5-HT2A receptor antagonist and a dopamine D2 receptor antagonist. It also functions as a serotonin transporter (SERT) inhibitor and has partial agonist activity at dopamine D1 receptors. Additionally, it modulates glutamate via effects on NMDA receptors and mTOR signaling.
Olanzapine pamoate is a second-generation antipsychotic that antagonizes dopamine D2 and serotonin 5-HT2A receptors. It also binds to adrenergic α1, histamine H1, and muscarinic M1 receptors.
42 mg orally once daily, with or without food. Initiate at 42 mg/day; no dose titration required.
210 mg intramuscular injection every 2 weeks; range 150-300 mg; max 300 mg per dose. For olanzapine-naive patients, establish tolerability with oral olanzapine before initiation.

The terminal elimination half-life of lumateperone is approximately 18 hours, supporting once-daily dosing with steady state achieved within 5 days.
The terminal elimination half-life ranges from 30 to 60 days (mean ~45 days) after intramuscular injection, consistent with extended release from the depot formulation.
Following oral administration of lumateperone, approximately 81% of the dose is excreted in feces (mostly as metabolites) and 12% in urine (as metabolites). Less than 1% is excreted unchanged in urine.
Approximately 57% of the dose is excreted in urine (30% as unchanged drug, 27% as metabolites) and 30% in feces (primarily as metabolites).
