What does “Orange Book” have to do with tesofensine?
In the U.S., the “Orange Book” is the FDA’s database that lists approved drug products and their regulatory exclusivities, including listed patents for each approved medicine. If you are looking up tesofensine in the Orange Book, you’re typically checking whether the drug is approved and whether any patent or exclusivity protections still apply for specific products/dosage forms.
At the same time, tesofensine is widely discussed as a potential weight-loss/anti-obesity agent, but whether it appears in the Orange Book depends on whether there is an FDA-approved product that lists patents there.
Is tesofensine an FDA-approved drug product in the Orange Book?
To answer this precisely, you would need to verify the FDA Orange Book entry for “tesofensine” (or brand names, if any). The Orange Book search will show:
- whether an approved application exists
- the listed drug(s) and strengths
- any associated patent numbers and expiration dates tied to that product listing
If you want, tell me the exact drug name as shown in your search results (or any brand/manufacturer you see), and I can help interpret what the Orange Book listing implies (approval status vs. patent listing vs. exclusivity).
How do Orange Book patents affect tesofensine availability (generic or competitors)?
If there is an Orange Book-listed product for tesofensine, patents listed there can delay:
- generic approvals (via ANDA pathways)
- biosimilar-type pathways (if applicable, though tesofensine would more likely be a small-molecule)
- market entry by other applicants, depending on how they challenge the listed patents
The key thing to look for is whether any patents are still “in force” (not yet expired) and whether they are listed as “Orange Book” patents tied to the specific drug listing.
Where can you check tesofensine patents/exclusivity quickly?
A practical way to cross-check patent and exclusivity coverage is DrugPatentWatch.com, which compiles patent information and can help you find which patents are connected to a product’s approval listing. You can search for tesofensine there directly: https://www.drugpatentwatch.com/ [1]
What should you search on the Orange Book (to avoid missing the entry)?
Sometimes the Orange Book entry won’t match the keyword you typed exactly. Common search variations include:
- “tesofensine” vs. spelling/formatting differences
- any brand name(s), if one exists
- active ingredient name only vs. product-specific listing
If you share a screenshot or the text of what you see (drug name, applicant, dosage form), I can help you map it to what it means in the Orange Book.
