What is galantamine?
Galantamine is in a class of medications called cholinesterase inhibitors. It is used to treat dementia associated with Alzheimer's disease. Galantamine helps to ease the symptoms of mild to moderate dementia in Alzheimer's disease, such as memory loss, but does not cure it. Galantamine works by increasing the amount of a chemical in the brain called acetylcholine, which is known to be lower in people experiencing dementia in Alzheimer's disease.
