Namenda XR works by blocking excess activity of glutamate, which may reduce the symptoms associated with Alzheimer's disease. This extended-release capsule is an N-methyl-D-aspartate (NMDA)-receptor antagonist. Namenda XR is used to treat moderate to severe Alzheimer-type dementia but is not a cure for Alzheimer disease.
Namenda XR (memantine) is a medication used to treat severe to moderate confusion related to Alzheimer's. Alzheimer's is a condition in which the patients lose their memory. Namenda XR does not treat Alzheimer's, but it can improve the memory, awareness, and the ability of the patient to go about their daily activities. The medicine works by blocking the action of certain chemical or natural substances (glutamate) in the brain. Glutamate is believed to be the primary chemical causing the Alzheimer's disease. Namenda XR is supplied as tablets or solution, and it should be taken by mouth with or without food. Back pain, constipation, stomach pains, and dizziness are some of the side effects of Namenda XR.
