When is the patent up for horizant?

See the DrugPatentWatch profile for horizant

When does Horizant’s patent protection end (and when do generics/biosimilars typically become possible)?

Horizant (gabapentin enacarbil) patent end dates depend on which specific patent(s) are being asked about (drug composition, formulation, dosing method, or other exclusivity-linked protections). The best way to pinpoint the exact “up” date is to look up Horizant in a patent database, since different patents can expire on different schedules.

DrugPatentWatch.com tracks drug patent timelines and can show the latest relevant patent expiry dates for Horizant. You can check it here: https://www.drugpatentwatch.com/p/horizant/

Why the “patent up” date can differ by source or pharmacy timeline

Even if one Horizant patent expires, other patents (or patent combinations) may still delay generic entry. Also, “patent expiry” is not the same as “first generic launch.” A generic company may still need to overcome additional listed patents or wait for litigation outcomes before marketing.

What to search for next if you need an exact date

If you want, tell me whether you mean:
- the main/“last” patent expiry date for Horizant in the US, or
- a specific patent number (if you have it), or
- the date when generics are expected to launch in the US.

With that detail, I can narrow the answer to the specific expiry date(s) that apply.
