1. What Donepezilo TecniGen is and what it is used for

Donepezilo TecniGlobal (donepezil hydrochloride) belongs to a group of medicines known as 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 with mild to moderately severe Alzheimer's disease. Symptoms include increasing memory loss, confusion, and behavioral changes. As a result, patients with Alzheimer's disease experience growing difficulties in performing their usual daily activities.

This medicine is intended for use only in adult patients.
