THERAPEUTIC CLASSIFICATION
N-methyl-D-aspartate (NMDA) receptor antagonist
ACTION AND CLINICAL PHARMACOLOGY
Persistent activation of the 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. It
blocks the effects of
pathologically
elevated sustained levels of glutamate that may lead to neuronal
dysfunction.
There is no clinical evidence that memantine prevents or slows
neurodegeneration or alters the
course of the underlying
dementing process in patients with Alzheimer’s disease. Memantine
exhibits low to negligible
affinity for other receptors (GABA, benzodiazepine,
dopamine,
adrenergic, noradrenergic, histamine and glycine) or voltage-dependent
Ca
2+
, Na
+
or K
+
channels. In addition,
it does not directly affect the acetylcholine receptor or cholinergic
transmission, which have been implicated in the cholinomimetic
side effects (e.g., increased
gastric acid secretion, nausea and vomiting)
seen with acetylcholinesterase inhibitors. Memantine
showed antagonist effects at the 5HT
3
receptor with a potency similar to that for the NMDA
receptor.
In vitro studies have shown that memantine does not affect the
reversible inhibition
of
acetylcholinesterase by donepezil or galantamine.
