Several medications are approved by the U.S. Food and Drug Administration to treat symptoms of Alzheimer's. Donepezil (AriceptÂ®), rivastigmine (ExelonÂ®), and galantamine (RazadyneÂ®) are used to treat mild to moderate Alzheimer's (donepezil can be used for severe Alzheimer's as well). Memantine (NamendaÂ®), is used to treat moderate to severe Alzheimer's.
This leads to increased concentrations of acetylcholine in the brain, and the increased concentrations are believed to be responsible for the improvement seen during treatment with donepezil. Donepezil improves the symptoms but does not slow the progression of Alzheimer's disease. Donepezil was approved by the FDA in 1996. PRESCRIBED FOR: Donepezil is used for the treatment of mild, moderate, or severe dementia associated with Alzheimer's disease. Medically Reviewed by a Doctor on 12/30/2014.
