What is Namenda prescribed for?

Namenda is used to treat moderate to severe dementia in adults with Alzheimer’s disease. It does not cure Alzheimer's disease, but it helps reduce dementia symptoms such as memory, awareness, and the ability to perform daily functions. This medication will not stop or slow the progression of Alzheimer’s disease from getting worse.

You can buy Namenda (Memantine) online at My Drug Center. We have the Namenda generic, called Memantine) available for purchase as well.


How does Namenda work?

Namenda is available as a tablet for oral administration, and it contains the active ingredient Memantine, which belongs to a class of drugs called NMDA receptor atagonists. The Memantine dosage in the medication works by blocking a natural substance in the brain called glutamate. This decreases the harmful effect of glutamate in the brain and may help improve your symptoms of dementia.
