Mode of Action
Memantine: Low- to moderate-affinity uncompetitive N-methyl-D-aspartate (NMDA) receptor (NMDAR) antagonist that binds preferentially to NMDAR-operated cation channels, blocking receptor only under conditions of excessive stimulation, with no effect on normal neurotransmission
Donepezil: Acetylcholinesterase inhibitor that causes an increase in concentrations of acetylcholine, which in turn enhances cholinergic neurotransmission
