CAPLYTA vs SAPHRIS
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.
Asenapine is an atypical antipsychotic with high affinity for serotonin 5-HT2A, 5-HT2C, 5-HT6, and 5-HT7 receptors; dopamine D2, D3, and D4 receptors; and alpha2-adrenergic receptors. It also has moderate affinity for histamine H1 and alpha1-adrenergic receptors, and low affinity for muscarinic M1 receptors.
42 mg orally once daily, with or without food. Initiate at 42 mg/day; no dose titration required.
5 mg sublingually twice daily, may increase to 10 mg twice daily based on tolerability and efficacy.

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 is 30-40 hours, supporting once-daily dosing.
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.
After oral administration, approximately 50% of the dose is excreted in urine (mostly as metabolites, <1% unchanged) and 40% in feces (mostly as metabolites).
