1. WHAT Donepezil hydrochloride
is and what it is used for
Donepezil hydrochloride (donepezil hydrochloride)
belongs to a group of medicines called
acetylcholinesterase inhibitors. Donepezil increases the
levels of a substance (acetylcholine) in the brain
involved in memory function by slowing down the
breakdown of acetylcholine.
It is used to treat the symptoms of dementia in people
diagnosed as having mild and moderately severe
Alzheimer’s disease. The symptoms include increasing
memory loss, confusion and behavioural changes. As a
result, sufferers of Alzheimer’s disease find it more and
more difficult to carry out their normal daily activities.
Donepezil hydrochloride is for use in adult patients only.
