How did U.S. Aricept (donepezil) sales perform over time?
Aricept is the brand name for donepezil, a dementia medicine (used for Alzheimer’s disease). In the U.S., Aricept sales have historically tracked the size of the diagnosed Alzheimer’s patient population and prescribing patterns for cholinesterase inhibitors.
The provided information here does not include specific U.S. sales figures, time series, or revenue by year for Aricept.
What companies sell Aricept in the U.S., and who controls U.S. revenue?
Aricept’s U.S. commercial history involves the brand manufacturer and, later, the impact of generic competition as exclusivity and patents expire. That transition typically causes a sharp decline in brand revenues and shifts market share toward generics.
The provided information here does not include the current U.S. marketer for Aricept or any brand-vs-generic market-share figures.
Has Aricept faced generic competition in the U.S., and when?
Brand medicines like Aricept commonly lose revenue after patent or exclusivity expires and generics enter. Those milestones can be checked through patent/exclusivity tracking resources.

Where can I find the exact U.S. Aricept sales numbers?
For the most exact U.S. sales figures, common sources are:
- company annual reports / investor presentations (brand revenue line items)
- IQVIA/other market research (often paywalled)
- regulatory or payer datasets (less consistent for brand-level figures)
The information provided here does not include those numeric figures.
If I want “Aricept sales in the U.S.” for a specific year, what should I specify?
To pull the right numbers, you can narrow the ask by:
- the year(s) (e.g., 2018–2023)
- whether you mean brand-only revenue or total donepezil prescriptions
- whether you want units, dollars, or market share
If you tell me the year range and whether you want brand sales or total drug market, I can format the answer around that target.
