LUMATEPERONE TOSYLATE vs QUETIAPINE FUMARATE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Lumateperone tosylate is an atypical antipsychotic with a unique mechanism of action involving antagonism of serotonin 5-HT2A receptors, partial agonism of serotonin 5-HT1A receptors, and antagonism of dopamine D2 receptors; it also modulates glutamate via phosphorylation of GluN2B subunits and inhibits serotonin reuptake.
Antagonist at serotonin 5-HT2A, dopamine D2, histamine H1, alpha1-adrenergic, and muscarinic M1 receptors. Also partial agonist at serotonin 5-HT1A and dopamine D2 receptors (depending on dose).
42 mg orally once daily
Immediate release: 25-100 mg orally twice daily, titrated as needed up to 400-800 mg/day divided twice daily. Extended release: 50-200 mg orally once daily, titrated up to 400-800 mg/day once daily.

Terminal elimination half-life is approximately 24-29 hours, allowing once-daily dosing. Steady-state reached in about 5 days.
Terminal elimination half-life is approximately 6-7 hours (quetiapine) and 9-12 hours for the active metabolite norquetiapine; with extended-release formulation, effective half-life is ~7 hours due to slower absorption. Clinical steady-state achieved within 2 days.
Approximately 60% excreted in urine as metabolites (unchanged drug negligible) and 30% in feces via biliary elimination.
Renal: 73% (20% unchanged, remainder as metabolites); Fecal: 21%; Approximately 5% excreted in feces as unchanged drug.
