Donepezil Hydrochloride is a prescription cholinesterase inhibitor used to treat symptoms of Alzheimer’s disease and other dementias. It works by increasing acetylcholine levels in the brain to improve memory, awareness, and daily functioning. While not a cure, Aricept can slow cognitive decline and enhance quality of life in patients with mild to severe Alzheimer’s disease.
