Why is this medication prescribed?
Namenda is a brand name for the medication memantine, which is commonly prescribed for the treatment of Alzheimer’s disease. Alzheimer’s disease is a progressive neurological disorder that affects memory, thinking, and behavior. Namenda is an N-methyl-D-aspartate (NMDA) receptor antagonist, which means it works by regulating the activity of glutamate, a neurotransmitter involved in learning and memory processes.
Namenda is prescribed to help manage the symptoms of moderate to severe Alzheimer’s disease. It is not a cure for the disease, but it may temporarily improve cognitive function, memory, attention, and the ability to perform daily activities. The medication may also help with reducing behavioral symptoms such as agitation and aggression.
