Recent phase 3 clinical trials have shown that Memantine is an effective way of treatment of both mild and moderate-to-severe Alzheimer''s disease and possibly vascular dementia (multi-infarct dementia). Memantine’s method of action involves an uncompetitive, low-affinity, open-channel blocker; it enters the receptor-associated ion channel preferentially when it is excessively open, and, most importantly, its off-rate is relatively fast so that it does not substantially accumulate in the channel to interfere with normal synaptic transmission.
정의
ChEBI: A primary aliphatic amine that is the 3,5-dimethyl derivative of 1-aminoadamantane. A low to moderate affinity uncompetitive (open-channel); NMDA receptor antagonist which binds preferentially to the NMDA receptor-operated cation channels.
생물학적 활성
An antagonist at the NMDA receptor, binding to the ion channel site. Used in the treatment of Parkinsonism.
