Here is some information about Aricept:

  1. Alzheimer's Disease: Aricept is approved for the symptomatic treatment of mild to moderate Alzheimer's disease. It does not cure or reverse the underlying disease but may help improve cognitive function and daily living activities for some individuals.
  2. Mechanism of Action: Medicine works by inhibiting the enzyme acetylcholinesterase, which breaks down the neurotransmitter acetylcholine in the brain. By inhibiting this enzyme, Aricept helps to increase the levels of acetylcholine, which is important for cognitive processes such as memory and thinking.
  3. Dosage and Administration: Donepezil is available in tablet form and is typically taken once daily in the evening, with or without food. The dosage may start low and gradually increase as tolerated.
  4. Regular Use: Drug is intended for regular, ongoing use. It is important to continue taking the medication as prescribed, even if you start to feel better. Stopping the medication suddenly may result in a decline in cognitive function.
  5. Effectiveness: The response to Aricept may vary among individuals. Some people may experience significant improvements in cognitive function, while others may have a more modest response or no noticeable change.

  3. Do Not Crush or Chew: Swallow the tablet whole and do not crush, chew, or break it. The tablet formulation is designed to release the medication gradually.
