Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Selective serotonin 5-HT2A receptor inverse agonist and antagonist; also has moderate affinity for 5-HT2C and 5-HT1A receptors.
Partial agonist at D2 and 5-HT1A receptors; antagonist at 5-HT2A and α1B/α2C adrenergic receptors.
34 mg orally once daily.
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 50 hours (range 40-70 hours), allowing once-daily dosing.
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.
Fecal (approximately 60%) as unchanged drug and metabolites; renal (approximately 13%) as unchanged drug and metabolites.
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%).
