Donepezil
About Donepezil
Donepezil belongs to the group of medicines called 'anti-Alzheimer's drug', primarily indicated in the treatment of dementia of the Alzheimer’s disease. In Alzheimer's disease, the brain cells degenerate and die, which causes a gradual decline in behavioural and social skills and thinking ability (dementia), which affects a person's ability to function independently. The signs include confusion, increasing memory loss, and behavioural changes.
Donepezil contains Donepezil that falls in the category of drugs called acetylcholinesterase inhibitors. This drug increases the levels of a substance (acetylcholine) in the brain, which is involved in improving memory functioning by slowing down the breakdown of acetylcholine (a substance that allows nerves to communicate and important for normal brain functioning).
