CLOZAPINE vs REXULTI
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Atypical antipsychotic; binds to dopamine D4, serotonin 5-HT2A, and adrenergic α2 receptors; weak D2 antagonist with rapid dissociation; also affects histaminergic and cholinergic receptors.
Partial agonist at D2 and 5-HT1A receptors; antagonist at 5-HT2A and α1B/α2C adrenergic receptors.
Initial: 12.5 mg orally once or twice daily; titrate gradually by 25-50 mg/day to target dose 300-450 mg/day in divided doses; max 900 mg/day.
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 8 to 12 hours (steady-state), but can range from 4 to 66 hours; requires dose adjustment in renal/hepatic impairment.
Clinical Note
moderateClozapine + Norfloxacin
"Clozapine may increase the QTc-prolonging activities of Norfloxacin."
Clinical Note
moderateClozapine + Torasemide
"The risk or severity of adverse effects can be increased when Clozapine is combined with Torasemide."
Clinical Note
moderateClozapine + Etacrynic acid
"The risk or severity of adverse effects can be increased when Clozapine is combined with Etacrynic acid."
Clinical Note
moderateClozapine + Furosemide
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 50% of the dose is excreted in urine (30% as unchanged drug and metabolites) and 30% in feces via biliary elimination.
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%).
