Donepezil is used to treat mild to moderate dementia; a conditions known as Alzheimer’s disease. The drug works by improving the function of nerve cells in the brain. It does this by preventing the breakdown of acetylcholine – a chemical in the brain. Acetylcholine is essential in the processes of reasoning, thinking and memory. People suffering from dementia have a low level of this chemical.
It is important to note that Donepezil does not cure Alzheimer’s disease. The disease will progress with time even when using this medicine.
Donepezil may be prescribed for other purposes not mentioned in this guide.
