Tranexamic acid patent expiration date?

There isn’t a single “Tranexamic acid patent expiration date.” Patent expiry depends on:

- which patent (the basic compound patent vs. a use patent vs. a formulation/salt patent)
- the country/region
- any term extensions or pediatric extensions that might apply

In short, the core patents on tranexamic acid (the molecule itself) have long since expired in most major markets, and tranexamic acid is widely available as a generic. However, there may still be active patents in some jurisdictions on specific uses (e.g., certain surgical indications), formulations, or salt forms.

If you want a precise expiry date, tell me:
- the country or region (e.g., US, EU, UK, Japan)
- whether you mean the basic molecule patent, a specific use patent, or a particular formulation/salt patent

I can then guide you to the exact patents and show how to determine their expiry dates. If you’d like, I can also help you search patent databases (USPTO, Espacenet, Google Patents, WIPO PATENTSCOPE) and interpret the results.
