Donepezil is used in the treatment of Alzheimer's disease and dementia associated with Parkinson's disease. It should be administered to patients with moderate to severe Alzheimer's disease.
How Donepezil works Memory loss in Alzheimer’s disease occurs due to disturbances in signal transmission in the brain. Donepezil is a cholinesterase inhibitor that works by increasing the levels of a chemical messenger, acetylcholine, which is involved in the transmission of nerve signals. This enhancement improves memory and cognitive function.
Common side effects of Donepezil include nausea, diarrhea, insomnia (difficulty sleeping), weight loss, and accidental injury.
