CAPLYTA vs INVEGA HAFYERA
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 palmitate is an atypical antipsychotic that antagonizes D2 and 5-HT2A receptors, with additional antagonism at alpha2, alpha1, and H1 receptors.
42 mg orally once daily, with or without food. Initiate at 42 mg/day; no dose titration required.
INVEGA HAFYERA (paliperidone palmitate) is dosed once weekly via intramuscular injection in the gluteal or deltoid muscle. The recommended starting dose is 1,092 mg (deltoid or gluteal) or 1,560 mg (gluteal only) on treatment day 1 and day 8, both given in the deltoid muscle. Subsequent maintenance doses are administered once monthly. Note: INVEGA HAFYERA is only for once-weekly administration; once-monthly formulations (INVEGA SUSTENNA) are also available.

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 25-49 days (mean ~36 days) due to slow dissolution from intramuscular depot. Steady-state reached after 4-5 monthly injections.
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 renal: 59% of paliperidone excreted unchanged in urine; 32% as metabolites; 6-12% fecal. Biliary excretion is minimal.
