LUMATEPERONE TOSYLATE vs Quetiapine
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, and adrenergic α1 receptors; weak partial agonist at 5-HT1A and serotonin transporter.

Clinical Note
moderateQuetiapine + Fluticasone propionate
"The risk or severity of adverse effects can be increased when Quetiapine is combined with Fluticasone propionate."
Terminal elimination half-life is approximately 24-29 hours, allowing once-daily dosing. Steady-state reached in about 5 days.
Terminal elimination half-life: ~6-7 hours (parent drug); extended-release: ~7 hours. Clinically, dosing is twice daily for immediate-release; once daily for extended-release.
Approximately 60% excreted in urine as metabolites (unchanged drug negligible) and 30% in feces via biliary elimination.
Renal: 73% (as metabolites), Fecal: 20% (as metabolites), unchanged drug: <1% renal
