Mechanism of action

Memantine blocks the NMDA receptor ion channel in a use-dependent manner, allowing it to preferentially inhibit pathological overactivation of glutamate signaling while preserving normal synaptic transmission. This mechanism protects neurons from excitotoxic damage associated with neurodegenerative conditions. The drug is thought to restore the balance of neuronal activity disrupted in Alzheimer's disease and other cognitive disorders.
