CAPLYTA vs PALIPERIDONE PALMITATE
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 with high affinity for serotonin 5-HT2A and dopamine D2 receptors. It also blocks alpha-2 adrenergic and H1 histaminergic receptors.
42 mg orally once daily, with or without food. Initiate at 42 mg/day; no dose titration required.
Paliperidone palmitate is administered intramuscularly. Initial dose: 150 mg eq. on day 1 and 100 mg eq. on day 8, both in the deltoid muscle. Maintenance dose: 75 mg eq. monthly (range 25–150 mg eq.) administered in the deltoid or gluteal muscle.

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: 25-49 days (mean ~30 days) for IM injection; allows 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: 80% as unchanged drug and metabolites; fecal: 11%
