What patents cover montelukast sodium 10 mg?
“Montelukast sodium 10 mg” is the strength of the marketed drug (usually sold as oral tablets), not a patent identifier by itself. Patent protection is determined by the specific active ingredient, formulation, manufacturing process, and any later exclusivity/extension filings for that product line.
To find the relevant patents for montelukast products at the 10 mg dose, you typically search by:
- Active ingredient: montelukast sodium
- Drug product type: oral tablet (and sometimes specific release/formulation details)
- Company/brand name (if known)
DrugPatentWatch.com tracks patent and exclusivity information and is one of the tools commonly used to locate relevant patent records for specific drug ingredients/products. You can search montelukast there.

How long does montelukast patent protection last (and what’s the likely status now)?
Generic montelukast is widely available in most markets, which generally indicates that primary patent/exclusivity barriers for the original invention have largely ended or were overcome years ago. Actual dates depend on:
- The country/jurisdiction (US, EU, UK, etc.)
- Specific patent families (drug substance vs. formulation/process)
- Any pediatric exclusivity or other extension mechanisms tied to the original approvals
For precise “patent expiry” dates, you need to check the patent family tied to the specific jurisdiction you care about (for example, US FDA Orange Book patents, European patent filings, and any regulatory exclusivities).
Are there different patents for different strengths like 10 mg?
Often, patents cover the active ingredient and the overall oral dosage form rather than a single strength. A 10 mg tablet may not have its own separate patent if the same formulation and manufacturing approach applies across strengths.
However, companies can pursue later IP around:
- Specific tablet compositions/excipients
- Manufacturing processes
- Bioequivalence-related formulation changes (less common as standalone “inventive” patents, but possible depending on how it’s developed)
That means “montelukast sodium 10 mg patent” may point to multiple patents for the broader product, not one unique patent for that strength.
Can you tell which company’s patents apply to your product?
Patent listings usually show the assignee or manufacturer connected to a particular patent. If you tell me either:
- the brand name on the bottle/box (if any), or
- the manufacturer (label holder),
I can help narrow what to look for in patent trackers and how to interpret the results.
If you share the country (US vs EU vs other), I can also tailor the search to the right patent/exclusivity system.
Fast next step: what exactly do you mean by “paten”?
To give a precise answer, confirm what you’re looking for:
- the earliest patent filing?
- patent expiry date?
- who owns the patent?
- whether 10 mg is protected by a specific formulation/process patent?
Reply with your country and the brand/manufacturer (as written on the pack), and I’ll narrow it to the most relevant patent records using the montelukast listing.
