What is the function of Aricept?

Aricept, known generically as donepezil, is specifically designed to treat dementia associated with Alzheimer's disease. It works by increasing levels of acetylcholine, a neurotransmitter that plays a key role in memory and cognitive function. This can help improve symptoms such as memory loss, confusion, and problems with thinking and reasoning in individuals with Alzheimer's.

The other options relate to different medical conditions and their treatments. Treatments for hypertension usually involve medications that lower blood pressure, while pain relief is typically managed through analgesics, and allergy management involves antihistamines or corticosteroids. These areas do not relate to the primary use of Aricept, which is distinctly focused on addressing cognitive decline in Alzheimer's patients.
