In Alzheimer’s disease, many chemical changes take place in the brain. One of the earliest and biggest changes is that there is less of a chemical called acetylcholine (ACh). ACh helps the brain to work properly.

Galantamine is used to treat mild to moderate dementia (memory loss and mental changes) that is a sign of Alzheimer’s disease. It can improve the thinking ability in some patients with Alzheimer’s disease. It slows the breakdown of ACh, so it can build up and have a greater effect. However, as Alzheimer’s disease gets worse, there will be less and less ACh, so galantamine may not work as well.
