Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Inhibits acetylcholinesterase, prolonging the action of acetylcholine at nicotinic and muscarinic receptors, enhancing neuromuscular transmission.
Galantamine is a reversible competitive acetylcholinesterase inhibitor and an allosteric modulator of nicotinic acetylcholine receptors, enhancing cholinergic function in the central nervous system.
2 mg intravenous (IV) or intramuscular (IM) as a test dose; for myasthenia gravis diagnosis: 2 mg IV test dose followed by 8 mg IV after 30 seconds if no reaction; for myasthenic crisis: 2 mg IV; for reversal of nondepolarizing neuromuscular blockade: 0.5-1 mg/kg IV.
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 elimination half-life is 1-2 hours in healthy adults; prolonged up to 4-6 hours 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.
Primarily renal excretion of unchanged drug (approximately 70-80%) with minor biliary excretion (10-15%).
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%).
