Research into Alzheimer's disease (AD) pathology has identified several underlying disease processes that are potential targets for drug discovery and development. One strategy targets glutamatergic neurotransmission mediated by the N-methyl-D-aspartate (NMDA) receptor. Therapeutic intervention with high-affinity NMDA receptor antagonists, such as phencyclidine (PCP) and MK-801, is not practical due to adverse side effects; however, a low-moderate affinity, uncompetitive and strongly voltage-dependent NMDA receptor antagonist, memantine (Namenda™), is well tolerated and recently has been approved by the U.S. Food and Drug Administration for the treatment of moderate to severe AD. Clinical results support NMDA receptor antagonism as a viable therapeutic strategy for AD and suggest that this novel pharmacologic approach, either alone or in combination with other drugs, is likely to significantly impact the current AD treatment paradigm.
