LUMATEPERONE vs Quetiapine
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Lumateperone is an atypical antipsychotic with a unique mechanism of action: it acts as a 5-HT2A receptor antagonist, a dopamine D2 receptor antagonist, and a serotonin reuptake inhibitor. It also modulates glutamate via enhanced AMPA and NMDA receptor activity.
Antagonist at serotonin 5-HT2A, dopamine D2, histamine H1, and adrenergic α1 receptors; weak partial agonist at 5-HT1A and serotonin transporter.
42 mg orally once daily, taken with food and at least 240 mL of water, with a titration schedule: 42 mg daily for 7 days, then 21 mg twice daily thereafter.
Initial: 25 mg PO BID, titrate to effective range 150-750 mg/day divided BID-TID; schizophrenia: 150-750 mg/day, bipolar disorder: 400-800 mg/day, major depressive disorder (adjunct): 150-300 mg/day at bedtime.

Clinical Note
moderateQuetiapine + Levofloxacin
"Quetiapine may increase the QTc-prolonging activities of Levofloxacin."
Clinical Note
moderateQuetiapine + Norfloxacin
"Quetiapine may increase the QTc-prolonging activities of Norfloxacin."
Clinical Note
moderateQuetiapine + Gemifloxacin
"Quetiapine may increase the QTc-prolonging activities of Gemifloxacin."
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 13 hours in the plasma, supporting once-daily dosing. Steady state is reached within 5–7 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 80% of the dose is excreted in feces (as unchanged drug and metabolites) and about 11% in urine. Less than 1% is excreted as unchanged lumateperone in urine.
Renal: 73% (as metabolites), Fecal: 20% (as metabolites), unchanged drug: <1% renal
