CAPLYTA vs ZIPRASIDONE HYDROCHLORIDE
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.
Ziprasidone is an atypical antipsychotic with high affinity for serotonin 5-HT2A and dopamine D2 receptors. It also antagonizes 5-HT2C, 5-HT1D, and alpha1-adrenergic receptors, and has moderate affinity for histamine H1 and alpha2-adrenergic receptors. It exhibits partial agonism at 5-HT1A receptors.
42 mg orally once daily, with or without food. Initiate at 42 mg/day; no dose titration required.
20 mg PO BID with food, titrated up to max 80 mg PO BID; IM: 10-20 mg q2h or q4h, max 40 mg/day

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 approximately 7 hours (range 6–10 hours) for oral administration; clinically, steady state is achieved within 1–3 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 via aldehyde oxidase and CYP3A4; <1% excreted unchanged in urine, approximately 20% in feces as metabolites.
