Mechanism of action

Memantine selectively blocks NMDA receptor channels in a use-dependent manner, reducing pathological calcium influx caused by chronic glutamate excitotoxicity while preserving normal synaptic transmission. This mechanism is thought to slow neuronal degeneration in Alzheimer's disease by protecting against excitotoxic damage without completely blocking physiological NMDA receptor function.
