MECHANISM OF ACTION OF MEMANTINE MEMANTINE IN AN UNCOMPETITIVE (LOW TO MODERATE AFFINITY TO) NMDA (N-METHYL-D-ASPARTATE) RECEPTOR ANTAGONIST. IT REGULATES THE ACTIVITY OF GLUTAMATE WHICH IS INVOLVED IN INFORMATION PROCESSING STORAGE AND RETRIEVAL. EXCESS GLUTAMATE PLAYS A ROLE IN NEURONAL CELL DEATH AND IT IS COMMON TO ALL NEURODEGENERATIVE DISEASES. IN ALZHEIMER`S DISEASE EXCESS RELEASE OF GLUTAMATE OCCURS.

MEMANTINE PREVENTS THESE ACTIONS BY INHIBITING THE BINDING OF GLUTAMATE AT NMDA RECEPTOR.
