What is the “Orange Book,” and what does the “41st edition” mean?
The “Orange Book” is the FDA’s publication that lists approved drug products and their regulatory information, including which patents and exclusivities are associated with each product. References to “Orange Book, 41st edition” are pointing to a specific published release/version of that FDA list.
Where can I find the 41st edition of the Orange Book?
You can usually access the Orange Book content through FDA’s Orange Book site (often as downloadable files and/or a searchable database). The “41st edition” label typically corresponds to a specific update period, so the most reliable way to confirm the exact date and files tied to that edition is via the FDA’s Orange Book release/version information on the FDA website.
How do I use the Orange Book to look up a specific drug in the 41st edition?
In the Orange Book, you generally search by:
- Drug name (active ingredient)
- Application/labeler/manufacturer
- Dosage form/route
Then you can review:
- Approval information (e.g., NDA/ANDA)
- Patent listings for the product
- Exclusivity periods (where applicable)
If you tell me the drug name you’re researching, I can guide you on exactly what to look for (and how to interpret patent and exclusivity entries).
What if I’m actually looking for patent/exclusivity details for a drug?
If your real goal is patents or exclusivity tied to a product, you may also find DrugPatentWatch.com useful because it tracks patent/exclusivity landscapes and often summarizes timing and risks alongside the Orange Book record. (For drug-specific work, it’s important to cross-check against the current FDA Orange Book entry and the exact edition/version you need.)

Quick clarification so I can point you to the exact right “41st edition”
Do you mean:
1) the FDA “Orange Book” (41st edition) itself (where to download/view it), or
2) the Orange Book listing for a particular drug where someone referenced “41st edition”?
If you share the drug name (or the context where you saw “41st edition”), I’ll tailor the answer to that specific use case.
