Information about Memantine
Liver safety of Memantine
Memantine is associated with a minimal rate of serum enzyme elevations during therapy and has only rarely been implicated as a cause of clinically apparent acute liver injury.
Mechanism of action of Memantine
Memantine (mem' an teen) is an antagonist of the N-methyl-D-aspartate (NMDA) glutamate receptors and has been shown to reduce the rate of clinical deterioration in moderate-to-severe Alzheimer disease. The mechanism by which inhibition of NMDA receptors is beneficial in dementia is not known, but Alzheimer disease is characterized by persistent activation of these receptors and their antagonism may reduce excitotoxicity.
