Memantine is a dissociative substance of the adamantane class that produces long-lived dissociative effects when administered. It is a derivative of amantadine and is pharmacologically related to compounds like PCP, ketamine, and DXM, although its recreational use is comparatively rare Memantine (1-amino-3, 5-dimethyladamanantate) is an adamantane derivative that blocks the NMDA receptor-associated ion channel similar to magnesium by binding to or near the magnesium-binding site (Lipton 2004) Common side effects of memantine may include: Dizziness or vertigo. Fatigue or drowsiness. Sense of confusion. Headaches. Stomach problems, including constipation. If an individual is displaying more serious side effects after taking memantine, these symptoms may be signs of a dangerous reaction

memantine. An NMDA (N-methyl D-aspartate) receptor antagonist that counters the toxic effects of glutamate excess to manage the symptoms of moderate to severe Alzheimer's disease. Adverse effects. Hallucinations, confusion, dizziness, headache, hypertonia, nausea, vomiting, constipation, hypertonia, cystitis, increased libido. Proposed mechanism Memantine is great. It is a long acting NMDA receptor antagonist that binds to an open channel binding site. This means that for memantine to bind, the neuron has to depolarize, and open to clear the magnesium block. Then memantine is pulled into the channel to its binding site Memantine Improves Global Impression (CGI-C) Responders [%] in CGI-C ITT analysis, N = 166 Response = improvement * p = 0.006, ** p = 0.001 versus placebo Winblad and Poritis., Int J Geriat Psychiatr 1999 Week 4 Week 12 * ** 80 70 60 50 40 30 20 10 0 59% 40% 73% 45% Memantine Memantine Placebo Placebo 58..

Memantine was used as a use-dependent blocker of NMDA receptors in nucleated patches pulled from stem-cell-derived dopamine neurons. Application of 0.5 µM memantine induced a significant decrease of NMDA receptors response. Washout for 4-5 minutes commonly returned the response amplitude to control values (see illustration) BRAND NAME (S): Namenda. USES: Memantine is used to treat moderate to severe confusion ( dementia) related to Alzheimer's disease. It does not cure Alzheimer's disease, but it may improve memory, awareness, and the ability to perform daily functions.

The partial N-methyl-D-aspartate (NMDA) antagonist memantine (Namenda, Namenda XR) is believed to work by improving the signal-to-noise ratio of glutamatergic transmission at the NMDA receptor.
