Namenda XR Titration Pack
Namenda XR is the brand name for memantine hydrochloride extended-release, a medication used to treat moderate to severe Alzheimer’s disease. It belongs to the N-methyl-D-aspartate (NMDA) receptor antagonist drug class. The Namenda XR Titration Pack is designed to help patients gradually increase their dosage to the optimal level in a controlled manner, reducing the risk of side effects. It works by regulating the activity of glutamate, a neurotransmitter in the brain, which is thought to play a role in the symptoms of Alzheimer’s disease.

Comprehensive Drug Guide
How Does Namenda XR Titration Pack Work?
Namenda XR works by blocking excess activity of glutamate in the brain, a neurotransmitter that, in excessive amounts, can overstimulate nerve cells and lead to neurodegeneration. By regulating glutamate activity, Namenda XR helps improve cognitive function and memory in patients with Alzheimer’s disease.
