CAPLYTA vs INVEGA SUSTENNA
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.
Paliperidone is an atypical antipsychotic that acts primarily as a central dopamine type 2 (D2) receptor antagonist and serotonin type 2A (5-HT2A) receptor antagonist. It also blocks α1- and α2-adrenergic receptors and H1 histamine receptors.
42 mg orally once daily, with or without food. Initiate at 42 mg/day; no dose titration required.
Initiate with 234 mg intramuscular injection on day 1, then 156 mg on day 8, both deltoid. Maintenance: 117 mg monthly (range 39-234 mg) via deltoid or gluteal injection. Dosing based on paliperidone palmitate.

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 ranges from 25 to 49 days (mean ~38 days) for deltoid injection and 30 to 50 days (mean ~45 days) for gluteal injection, supporting monthly 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.
Renal: approximately 59-80% as unchanged drug and metabolites, with about 1% unchanged; biliary/fecal: approximately 20-41% primarily as metabolites.
