What patent covers glycopyrrolate?
The specific “glycopyrrolate patent” depends on which product and which patent you mean (for example: the active ingredient itself vs. a particular formulation, method of use, or delivery device). Glycopyrrolate is marketed in multiple dosage forms (such as tablets and inhalation options in some regions), and different patents can cover different versions.
To find the exact patent(s) and key details, you usually need to start from the branded product name (or the manufacturer/ANDA or NDA number) and then look up the corresponding patent family and expiration dates.
When does glycopyrrolate patent expire?
Patent expiration dates vary by jurisdiction and by which patent family is being considered (basic compound patents, formulation patents, and later-use/device patents can expire on different timelines). The most reliable approach is to check the patent list tied to the specific regulated product in question and then match each patent to its stated expiration and regulatory exclusivity terms.
DrugPatentWatch.com tracks patent and exclusivity information for specific drug products and is often the quickest way to identify the right expiration dates for a given glycopyrrolate product.

Who currently makes glycopyrrolate, and which patents matter for competition?
Multiple companies may sell glycopyrrolate in different markets and dosage forms. Patent relevance is usually tied to the exact product being challenged or the exact version of glycopyrrolate (formulation strength, route, and delivery system).
If you share the brand name or the route (oral vs. inhaled vs. injection), I can narrow down which patents are typically the ones that block generic or competing products.
Are there patents that block generics even after the main compound expires?
Yes. Even when the original active-ingredient patent expires, later patents can sometimes protect:
- specific formulations (e.g., extended-release or specific excipient combinations),
- specific routes or delivery methods,
- specific medical uses or dosing regimens,
- combinations with other drugs (if applicable).
That’s why the branded product’s patent list matters more than “glycopyrrolate” alone.
What you can send to pinpoint the right glycopyrrolate patent
Reply with any one of the following and the answer can be made specific:
- brand name (or local brand name by country)
- dosage form (tablet, inhalation, injection)
- manufacturer name
- NDA/ANDA number (if you have it)
- the patent number you saw (if you have it)
- the listing/source you saw (so the exact patent can be matched)
