Quick Summary

Aricept, also known by its generic name donepezil, is a medication used to treat Alzheimer's disease. It belongs to a class of drugs called anticholinesterases, which work by preventing the breakdown of acetylcholine, a neurotransmitter crucial for nerve function. In Alzheimer's disease, there's a reduction in acetylcholine levels, contributing to cognitive decline. By inhibiting the breakdown of acetylcholine, Aricept helps to restore neurotransmitter levels, potentially slowing the degeneration of neurons and cognitive abilities. While Aricept can offer marginal benefits, its use is often limited to individuals with late-stage Alzheimer's disease, where the benefits are considered to outweigh the risks of side effects.1
