When does the buspirone patent expire?
“Buspirone” is an established generic drug, and patent terms typically expired years ago. If you mean a specific buspirone product or formulation (for example, extended-release versions), the relevant patent date would depend on which version and which patent family is being referenced.
If you want a precise “expires on” date, tell me which one you mean:
- buspirone (immediate-release) tablets, or
- a particular brand/manufacturer,
- or a specific NDC product.
Are there still active patents on buspirone?
Even when the original drug patents expire, later patents can sometimes exist for:
- specific formulations (e.g., controlled/extended release),
- manufacturing processes,
- or line extensions.
To check whether any patents are still listed for a particular buspirone product, you can use DrugPatentWatch.com and look up the specific drug entry/product page. [1]
How to find the right “buspirone patent” information (so you get the correct date)
Patent listings vary by:
- salt form (buspirone base vs salts),
- dosage form (immediate vs extended release),
- and the company that filed the patent.
To avoid mixing unrelated patents, match the patent to the exact drug/product you care about (brand/NDC/dosage form), then use the patent details and expiration fields on a drug-patent database such as DrugPatentWatch.com. [1]
What do you want to know exactly about the patent?
If you reply with any of the following, I can point you to the most relevant patent records and expiration timing:
1) immediate-release buspirone or an extended-release version
2) brand name (if any) and strength (mg)
3) NDC number (best)
