1. What Donepezil Krka is and what it is used for

Donepezil Krka contains the active substance donepezil hydrochloride. Donepezil Krka (donepezil hydrochloride) belongs to a group of medicines called acetylcholinesterase inhibitors. Donepezil increases the levels of a substance ( acetylcholine ) in the brain, which is involved in memory function, by delaying the breakdown of acetylcholine.

It is used to treat the symptoms of dementia in mild and moderate Alzheimer’s disease. These symptoms include increasing memory loss, confusion, and behavioral changes. As a consequence of these symptoms, those suffering from Alzheimer’s disease find it more and more difficult to perform normal daily activities.

Donepezil Krka should only be used by adults.
