What is Namenda XR?
Namenda XR is the brand name for the extended-release formulation of the drug memantine, an NMDA receptor agonist that is prescribed to treat certain symptoms of moderate to severe Alzheimer’s disease, especially dementia. It works by affecting certain chemicals in the brain that contribute to these symptoms.
