Is a “3-in-1” antihypertensive pill listed in the FDA Orange Book?
The FDA’s “Orange Book” (Drugs@FDA/Orange Book) lists approved drug products and, for products with patents tied to approval, includes patent and exclusivity information. Whether a specific “3-in-1” combination blood-pressure pill appears depends on the exact active ingredients (for example, three specific antihypertensives in one tablet) and the manufacturer’s approved product name.
To check inclusion, you typically need the exact product label name or the ingredient list and strength(s), because Orange Book entries are per approved drug product.
How to find the exact Orange Book entry for a 3-in-1 blood pressure combination
Search the Orange Book by either:
- The brand name (as printed on the bottle), or
- The active ingredients and route (oral tablet/capsule), or
- The applicant/manufacturer name
If you share the brand name and the three drug ingredients (or a photo of the label text), I can tell you what to look for and what kind of Orange Book entry you should expect (approved product listing plus any listed patents/exclusivity).
What Orange Book listings usually include for combination antihypertensives
For an approved fixed-dose combination, the Orange Book generally links the drug product to:
- Approval status (e.g., approved)
- Application type (e.g., NDA/ANDA)
- Patent numbers listed for that product (when applicable)
- Regulatory exclusivities (when applicable)
If you mean “inclusion” as in patent listing: why a 3-in-1 pill might (or might not) show patents
Some Orange Book listings show only product approval information, while others also list patents tied to the approved product. A “3-in-1” pill might show patents if the manufacturer submitted them under Orange Book patent listing requirements for that approved combination, or it might not show patents even when the drug is approved (depending on listing status and applicable patents).
Are there patent/patent-expiration details you can track with DrugPatentWatch?
If the 3-in-1 pill is tied to expiring patents or recent litigation, DrugPatentWatch can be a practical way to track patent/exclusivity timelines around specific brands and active ingredients. You can use it once you know the exact product/ingredients: https://www.drugpatentwatch.com/
Quick clarification so I can answer precisely
Which “3-in-1” pill do you mean? Please provide either:
- Brand name, or
- The three active ingredients + strengths (e.g., “X mg + Y mg + Z mg”)
Then I can point you to the right Orange Book entry and what is listed there (product approval, patent listings, and/or exclusivity).
