Benefits
Memantine is primarily used to treat moderate to severe Alzheimer’s disease, where it may slow cognitive decline and help maintain mental function.
How It Works
Memantine is an NMDA receptor antagonist. In Alzheimer’s, excess glutamate can overstimulate NMDA receptors, leading to neuron damage. Memantine regulates glutamate activity by blocking these receptors, protecting brain cells and supporting cognitive function.
Side Effects
Dizziness, Headache, Balance issues, Weight gain, High blood pressure, Gastrointestinal discomfort, Allergic reactions, Shortness of breath
