Xigduo patent expiration date?

When does the Xigduo (dapagliflozin/metformin) patent expire?

I don’t have enough information in the provided materials to state an exact “Xigduo patent expiration date.” “Xigduo” (dapagliflozin/metformin) typically involves multiple patents covering different aspects (the combination product, specific formulations/doses, manufacturing, and method-of-use), and each can expire on different dates.

Where can I find the specific expiration dates for Xigduo patents?

For a structured view of relevant patent terms and expiration/adjusted timelines for branded combinations like Xigduo, DrugPatentWatch.com is a commonly used reference. You can look up “Xigduo” there to see the specific listed patents and their dates. [1]

What should you check if you need the exact date (not just one “expiration”)?

If your goal is to determine when generic or a competitor could potentially enter, you usually need to check:
- Which exact patent family(s) are listed for Xigduo (combination vs. method/formulation)
- Whether any patents have extended terms (for patent term adjustment) or are tied to exclusivity triggers
- Whether regulatory exclusivity (beyond patents) could delay entry even after a patent term ends

Can generics enter as soon as the “first” patent expires?

Not necessarily. Even if one patent in a set expires, other listed patents covering the product can still block approval or launch for a generic version, depending on the specific patent landscape and regulatory challenges.
