Alzheimers Home > Aricept

Aricept, which is a prescription medicine, is used to treat symptoms related to Alzheimer's disease. The medication works by stopping a specific enzyme from breaking down acetylcholine in the brain, which can help improve memory, attention, reason, language, and the ability to perform simple tasks. Aricept comes as an oral tablet or an orally disintegrating tablet, and is available in several strengths.

How Does Aricept Work?

Aricept is part of a class of drugs known as acetylcholinesterase inhibitors. It works by stopping a specific enzyme (known as acetylcholinesterase) from breaking down acetylcholine in the brain. Acetylcholine is a chemical that aids in many brain functions, including memory, attention, reason, and language.
 

Aricept Effects

Patients with Alzheimer's generally have a decline in memory and learning that is related to the loss of acetylcholine in the brain. Since Aricept can prevent the breakdown of this chemical, more of it remains in the brain for a longer time. This helps to slow the decline in memory and learning, and allows a person with Alzheimer's symptoms to perform simple daily tasks. However, Aricept is not a cure for Alzheimer's and cannot slow the progression of the disease.
