Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Partial agonist at D2 and 5-HT1A receptors; antagonist at 5-HT2A receptors.
Positive allosteric modulator of GABA-A receptors, enhancing inhibitory neurotransmission.
Oral: 10-15 mg once daily; initial and target dose 10-15 mg; maximum 30 mg/day. IM: 9.75 mg single dose, then 5.25-9.75 mg every 2 hours if needed; maximum 30 mg/day.
58 mg subcutaneously once monthly (every 30 days).

Aripiprazole has a terminal elimination half-life of approximately 75 hours in extensive CYP2D6 metabolizers and about 146 hours in poor metabolizers. The active metabolite, dehydro-aripiprazole, has a half-life of about 94 hours. This long half-life allows for once-daily dosing and gradual achievement of steady state (14 days in extensive metabolizers).
Clinical Note
moderateAripiprazole + Torasemide
"Aripiprazole may increase the hypotensive activities of Torasemide."
Clinical Note
moderateAripiprazole + Etacrynic acid
"Aripiprazole may increase the hypotensive activities of Etacrynic acid."
Clinical Note
moderateAripiprazole + Furosemide
"Aripiprazole may increase the hypotensive activities of Furosemide."
Clinical Note
moderateAripiprazole + Bumetanide
"Aripiprazole may increase the hypotensive activities of Bumetanide."
The terminal elimination half-life of Sezaby is approximately 24 hours in healthy adults. This supports once-daily dosing. In patients with hepatic impairment, half-life may be prolonged.
Aripiprazole is extensively metabolized primarily by the liver via CYP2D6 and CYP3A4. Approximately 25% of the dose is excreted unchanged in urine, and about 55% in feces. The major metabolite, dehydro-aripiprazole, accounts for about 40% of the AUC and is also excreted in urine and feces.
Sezaby undergoes extensive hepatic metabolism, with approximately 75% of the dose excreted in feces as metabolites and 20% in urine as unchanged drug and metabolites. Renal clearance accounts for less than 5% of total clearance.
