Donepezil is manufactured by various pharmaceutical companies, often as both a branded medication and a generic option.
What are the different brand names for donepezil?
The most well-known branded version of donepezil is Aricept, originally developed by Eisai and Pfizer [1]. Over time, as patents expired, other companies began producing their own generic versions of donepezil.
Who makes generic donepezil?
Numerous pharmaceutical companies produce generic donepezil. Some of the manufacturers include Teva Pharmaceuticals, Apotex, Sun Pharmaceutical Industries, and Dr. Reddy's Laboratories, among others [2][3]. Availability of specific generic manufacturers can vary by region and pharmacy.
When did Aricept lose its patent protection?
Aricept, the original branded form of donepezil, faced patent expirations, leading to the introduction of generic versions. The primary patents for Aricept began to expire around 2010-2011 in the United States [4].
How does donepezil work?
Donepezil is an acetylcholinesterase inhibitor. It works by increasing the levels of acetylcholine, a neurotransmitter, in the brain [1]. Acetylcholine plays a role in memory and thinking, and its levels are often reduced in people with Alzheimer's disease. By inhibiting the enzyme that breaks down acetylcholine, donepezil helps to preserve this neurotransmitter.
