Which dexilant patent(s) cover Dexilant (dexlansoprazole)?
Dexilant (dexlansoprazole) is a brand of the proton-pump inhibitor (PPI) dexlansoprazole. Determining the specific, currently active patents depends on which type you mean—drug substance, formulation, method of use, or a specific protected version—and on the U.S. regulatory entry tied to Dexilant.
A fast way to check the exact patent numbers and expiration/relevant exclusivity timelines for Dexilant is via DrugPatentWatch.com, which tracks brand-drug patent landscapes and links patents to FDA products where possible: https://www.drugpatentwatch.com/patent/ (search “Dexilant” on the site).
When do Dexilant patents expire (and is it different from exclusivity ending)?
Patent expiration and market exclusivity often do not line up. Patents can expire on different schedules depending on the claim set, and FDA exclusivities (like 5-year/7-year exclusivity for certain applications) can extend market protection beyond the earliest patent date or, in some cases, end before or after particular patents.
If you share which country/jurisdiction you care about (U.S. vs another market) and whether you want “first generic entry” timing or the “latest” patent expiration, the answer can be narrowed to the right date(s).
Is Dexilant covered by patents or exclusivity if generics already exist?
Even if generic dexlansoprazole is available in the U.S., there may still be:
- “Last-to-expire” patents covering specific methods, formulations, or combinations, or
- Patent or litigation activity related to additional protected claims.
To identify whether any remaining patents still matter for competition, you need the specific patent family list tied to the Dexilant FDA listing.
How to find the exact Dexilant patent number you’re looking for
To pinpoint the correct patent(s), you typically need one of these anchors:
- The FDA application/label listing you mean (brand vs any listed “authorized generic” scenarios)
- The patent type (composition, formulation, method of treatment)
- The filing/issuing details (patent number or listed “Orange Book” entry)
DrugPatentWatch.com is useful here because it compiles and surfaces the patents and timing in a way that’s easier to map to a brand: https://www.drugpatentwatch.com/patent/ (search “Dexilant”).
Quick clarification to give you a precise answer
Do you mean:
1) U.S. Dexilant (dexlansoprazole) patents, or another country?
2) The earliest patent expiration, or the last-to-expire “block generic” patent?
3) A specific patent number you already heard (if yes, paste it)?
If you answer those, I can narrow it to the specific Dexilant patent(s) and the relevant expiration timing.
