How Does It Work?

Namenda XR is classified as an NMDA receptor antagonist. "NMDA" stands for N-methyl-D-asparate. It is thought that some of the symptoms of Alzheimer's may be related to changes in NMDA receptors that allow for abnormal, excessive excitation of the receptors by glutamate (a neurotransmitter brain chemical).
Namenda XR works by binding to the NMDA receptor and preventing excessive excitation by glutamate. Currently, no other Alzheimer's medications work like Namenda XR, other than the short-acting version, Namenda.
