The Nootropic Donepezil - a Short Description of its Effects

Donepezil Alvogen (donepezil-hydrochloride) belongs to the group of drugs known as acetylcholinesterase inhibitors, and it is also a nootropic (cognitive-enhancing) drug, more popularly known as "smart drug".

Donepezil increases the level of acetylcholine substance in brain. This change gets involved in the processes of memory, by slowing down the degradation process of acetylcholine.

This medicine is used for the treatment of the symptoms of dementia present in people suffering from Alzheimer's disease. Symptoms of Alzheimer's disease include loss of memory, confusion, and changes in behavior. Therefore, those who are affected by Alzheimer's disease hardly carry on with their usual daily routines. This nootropic drug was proven to mitigate the symptoms of this disease.

Being a nootropic and thus acting as memory-enhancing agent, it is also used among the rest of the population, among people who want to improve their memory and intellectual capacity. However, Donepezil is not recommended for that kind of free use due to its potential side-effects.

People who should not take Donepezil

In order to maintain a good mental and physical condition, it is of great significance to know when and how to use Donepezil. For example, you should not take it if you are allergic to donepezil-hydrochloride, piperidine derivatives, or to any other component of the medicine. In the case of intolerance to some sweeteners, notify your doctor before taking this drug, because it contains lactose.
