BLOXIVERZ vs RAZADYNE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
BLOXIVERZ is a selective serotonin reuptake inhibitor (SSRI) that potentiates serotonergic activity in the central nervous system by inhibiting the reuptake of serotonin at the serotonin transporter (SERT), leading to increased extracellular serotonin levels.
Galantamine is a reversible competitive acetylcholinesterase inhibitor and an allosteric modulator of nicotinic acetylcholine receptors, enhancing cholinergic function in the central nervous system.
10 mg intravenously every 12 hours; may increase to 15 mg every 12 hours based on clinical response.
Initial dose 8 mg/day PO (4 mg twice daily) for 4 weeks; increase to 16 mg/day (8 mg twice daily) for at least 4 weeks; maintenance 16-24 mg/day (12 mg twice daily). Extended-release: initial 8 mg PO once daily; after 4 weeks increase to 16 mg once daily; if tolerated, may increase to 24 mg once daily.

Terminal half-life 18 hours (range 14-22 h); clinical: steady state in ~3.5 days, dosing adjustments needed in renal impairment.
Terminal elimination half-life is approximately 7-8 hours in healthy adults, allowing twice-daily dosing; unchanged in mild to moderate hepatic impairment but prolonged in severe hepatic impairment.
Renal: 60% unchanged; Biliary/Fecal: 30% as metabolites; 10% other routes.
Renal excretion of unchanged drug accounts for approximately 20-25% of the dose; the remainder is metabolized by the liver and excreted as metabolites in urine (about 95% total) and feces (about 5%).
