Memantine

Drug Details

Memantine is a medication prescribed for managing moderate to severe dementia associated with Alzheimer's disease. While it does not cure Alzheimer's, it may help enhance memory, awareness, and daily functional abilities. Memantine functions as an NMDA (N-methyl-D-aspartate) antagonist, working by reducing the activity of glutamate, a chemical messenger in the brain that is often overly active in individuals with Alzheimer's. This action helps prevent further nerve damage and slows the progression of memory loss. Memantine is typically taken orally, either once or twice a day, depending on the form—extended-release capsules or regular-release tablets or oral solution. Users may experience side effects such as dizziness, headaches, and confusion. It is important to consult with a healthcare professional before starting any new medication.
