CLINICAL PHARMACOLOGY
Mechanism of Action and Pharmacodynamics
Persistent activation of central nervous system N-methyl-D-aspartate
(NMDA) receptors by the
excitatory amino acid glutamate has been hypothesized to contribute to
the symptomatology of
Alzheimer's disease. Memantine is postulated to exert its therapeutic
effect through its action as a low
to moderate affinity uncompetitive (open-channel) NMDA receptor
antagonist which binds
preferentially to the NMDA receptor-operated cation channels. There is
no evidence that memantine
