Galantamine is a prescription medication that is used to treat mild to moderate Alzheimer’s dementia. Patients that have dementia often have lower levels of the chemical acetylcholine which is important for thinking, reasoning, and memory. Galantamine works to improve the function of the nerve cells inside the brain by preventing the breakdown of acetylcholine.
