Five drugs have been approved by the U.S. Food and Drug Administration (FDA) for treating the cognitive symptoms of Alzheimer’s disease. Reminyl, Exelon, Aricept and Cognex belong to a class of drugs known as cholinesterase inhibitors. Each drug acts in a different way to delay the breakdown of acetylcholine, a chemical in the brain that facilitates communication among nerve cells and is important for memory. Alzheimer’s disease is associated with inadequate levels of this important neurotransmitter. Namenda acts by a different mechanism. It shields brain cells from overexposure to another neurotransmitter called glutamate, excess levels of which contribute to the death of brain cells in people with Alzheimer’s.
