LUMATEPERONE TOSYLATE vs UZEDY
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.
Atypical antipsychotic; antagonist at dopamine D2 and serotonin 5-HT1A/5-HT2A receptors; partial agonist at serotonin 5-HT1A receptors
42 mg orally once daily
UZEDY (risperidone) extended-release injectable suspension: 75 mg, 100 mg, 150 mg, or 200 mg IM gluteal injection every 2 weeks after a single oral dose of 2 mg risperidone for 2 days; or 25 mg, 50 mg, 75 mg, 100 mg, 125 mg, or 150 mg IM every 4 weeks after oral overlap for 2 days. Oral risperidone may be omitted if patient is stable on oral risperidone 2 mg/day.

Terminal elimination half-life is approximately 24-29 hours, allowing once-daily dosing. Steady-state reached in about 5 days.
Terminal half-life approximately 30 days (range 23–37 days) after subcutaneous injection, supporting monthly dosing.
Approximately 60% excreted in urine as metabolites (unchanged drug negligible) and 30% in feces via biliary elimination.
Primarily renal: 80% as metabolites, 1% unchanged. Biliary/fecal: 20%.
