Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Lurasidone is an atypical antipsychotic with high affinity for dopamine D2, serotonin 5-HT2A, and serotonin 5-HT7 receptors, and moderate affinity for serotonin 5-HT1A receptors. It acts as an antagonist at D2 and 5-HT2A receptors, and as a partial agonist at 5-HT1A receptors. The exact mechanism of action in schizophrenia and bipolar depression is unknown but is thought to involve modulation of these receptors.
Partial agonist at D2 and 5-HT1A receptors; antagonist at 5-HT2A and α1B/α2C adrenergic receptors.
40 mg orally once daily initially, titrated to 80-160 mg once daily; maximum 160 mg/day. Administer with food (at least 350 calories).
2 mg orally once daily initially; increase to 4 mg once daily no sooner than week 2; target dose 4 mg once daily; range 2-4 mg once daily.

Terminal elimination half-life is approximately 20–40 hours (mean about 29 hours) in adults, supporting once-daily dosing. Steady-state is reached within 7 days.
Terminal elimination half-life is approximately 19–23 days for brexpiprazole and its major metabolite DM-3411, requiring up to 2–3 months to reach steady state.
Approximately 80% of the dose is eliminated in feces (mostly as unchanged drug and metabolites) and about 10% in urine. Less than 2% is excreted as unchanged lurasidone in urine.
Approximately 25% of the dose is excreted in urine as unchanged drug and metabolites; about 54% is excreted in feces. Renal excretion of unchanged drug is minor (<1%).
