Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Reversible acetylcholinesterase inhibitor, prolonging the action of acetylcholine at nicotinic and muscarinic receptors.
Reversible, competitive acetylcholinesterase inhibitor, increasing acetylcholine concentrations in the synaptic cleft of the central nervous system, particularly enhancing cholinergic neurotransmission in the cerebral cortex and hippocampus.
Oral: 60-120 mg every 3-4 hours (max 360 mg/day). Intravenous: 0.1-0.25 mg/kg IV (max 10 mg per dose) for reversal of nondepolarizing neuromuscular blockade, given with glycopyrrolate or atropine. Intramuscular: 0.2-1 mg for postoperative urinary retention.
16 mg orally once daily in the morning; may increase to 24 mg once daily after minimum of 4 weeks; maximum dose 24 mg/day.
