CAPLYTA vs SEROQUEL
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.
Antagonist at dopamine D2 and serotonin 5-HT2A receptors; also blocks histamine H1 and adrenergic α1 receptors.
42 mg orally once daily, with or without food. Initiate at 42 mg/day; no dose titration required.
Initial: 25 mg twice daily; titrate by 25-50 mg twice daily on day 2 and 3 to target 300-400 mg daily in 2-3 divided doses. Maintenance: 400-800 mg daily. Maximum: 800 mg daily.

The terminal elimination half-life of lumateperone is approximately 18 hours, supporting once-daily dosing with steady state achieved within 5 days.
Terminal elimination half-life approximately 7 hours for quetiapine; for metabolite N-desalkylquetiapine (norquetiapine), approximately 12 hours. Steady-state reached within 2 days.
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.
Primarily hepatic metabolism; <1% excreted unchanged renally. Metabolites excreted in urine (73%) and feces (20%).
