BREXPIPRAZOLE vs LUMATEPERONE TOSYLATE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Partial agonist at dopamine D2 and serotonin 5-HT1A receptors; antagonist at serotonin 5-HT2A receptors.
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.
Oral: 1 mg once daily initially, titrate to 2 mg once daily after 3-7 days, then to 4 mg once daily based on response; maximum 4 mg once daily.

91 hours (range 70–120 hours) for the parent drug; repeated dosing leads to steady state in ~3–4 weeks. The active metabolite DM-3411 has a half-life of ~86 hours.
Clinical Note
moderateBrexpiprazole + Haloperidol
"The serum concentration of Haloperidol can be increased when it is combined with Brexpiprazole."
Clinical Note
moderateBrexpiprazole + Methylphenidate
"The risk or severity of adverse effects can be increased when Brexpiprazole is combined with Methylphenidate."
Clinical Note
moderateBrexpiprazole + Quinagolide
"The therapeutic efficacy of Quinagolide can be decreased when used in combination with Brexpiprazole."
Clinical Note
moderateTerminal elimination half-life is approximately 24-29 hours, allowing once-daily dosing. Steady-state reached in about 5 days.
Primarily hepatic metabolism via CYP3A4 and CYP2D6; ~25% renal excretion (mostly as metabolites), ~60% fecal excretion (mostly as metabolites).
Approximately 60% excreted in urine as metabolites (unchanged drug negligible) and 30% in feces via biliary elimination.
