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.
PHARMACOKINETICS
