Aricept (Donepezil)

What is Aricept?

Aricept, also known as donepezil is a drug used to prevent or reduce the breakdown of a specific chemical component in the human brain. Aricept is a new reversible inhibitor of the enzyme acetylcholinesterase which is responsible for the breakdown of the neurotransmitter acetylcholine. Aricept may cause a greater concentration of acetylcholine in the brain, thereby improving cholinergic function. Acetylcholine, associated with memory and learning, is in short supply in subjects with Alzheimer’s disease.

The neurons which are made of specialized brain cells, need to communicate constantly to distribute all the information from the brain to the rest of the body system. Thousands and thousands of reactions happen in order for a single thought to be formed, to establish their connections they need to send signals to each other and that’s the function of neurotransmitters like acetylcholine.

When there’s a breakdown in this chemical entity, neurons cannot communicate and send their signals through the brain and out to the rest of the body. The brain is the central motor of every single action, right? That is exactly what happens with patients diagnosed with dementia. There’s no recognition of signals and messages from the brain cells and that causes, slow or fast but continuous degradation of the central nervous system and all its functions, leading the person to lose little by little all his/her faculties and at last, his/her life.

Then you must be asking yourself and what is Aricept used for, then? Well, this drug offers a palliative treatment for dementia associated with Alzheimer, it won’t stop the disease, it’ll only buy time and improve some conditions that are present on the clinical case.
