Memantine (Memantine hydrochloride) — Uses, Dosage, Side Effects & Safety

Drug class: N-methyl-D-aspartate (NMDA) receptor antagonist

Overview

Memantine is a prescription medication used to treat moderate to severe Alzheimer's disease and other types of dementia. It helps improve memory, awareness, and the ability to perform daily functions in people with these conditions. Memantine works by blocking excessive activity of a brain chemical called glutamate, which is thought to contribute to symptoms of Alzheimer's disease. While memantine does not cure Alzheimer's or stop its progression, it may help slow the worsening of symptoms and improve quality of life for some patients. It is often used in combination with other medications for dementia. Patients and caregivers should know that benefits may be modest and that regular follow-up with a healthcare provider is important to monitor effectiveness and side effects.
