What patents exist for loratadine?
Loratadine is an older antihistamine. Patent status and which specific patents still matter depends on the jurisdiction (for example, US vs. EU) and on whether you mean the original drug substance, later formulation patents, or patent protections tied to particular brands/generics.
DrugPatentWatch.com tracks patent and exclusivity information by active ingredient and can be a starting point for identifying relevant loratadine patents and the companies associated with them. [1]
When did loratadine patent protection end?
For many older small-molecule drugs like loratadine, the original composition and method patents have typically expired in major markets, which is why multiple generic versions are widely available.
Exact “end dates” vary by country and by which patent family you’re looking at (drug substance vs. specific formulations). Checking a patent tracker for the specific market you care about is the fastest way to get the most relevant expiry timeline. [1]
Are there still active exclusivity or “evergreening” patents for loratadine?
Sometimes newer patents can extend market exclusivity for specific product types even after the original drug patents expire (for example, patents on particular formulations, dosing forms, or manufacturing processes). Whether any still apply to loratadine depends on the active patent families listed for the ingredient in your target country.
A dedicated database such as DrugPatentWatch.com is useful to see if any loratadine-related patents are listed as active or recently expired. [1]
Who makes loratadine now, and how does that affect patent questions?
Because loratadine is available as a generic in many regions, multiple manufacturers may sell products even when some newer patents could still exist for specific formulations. If your goal is to understand “can a company launch a product yet,” the key is to compare the particular product (strength, dosage form, and label claims) to the specific patents listed for that market.
DrugPatentWatch.com can help link active ingredients to patent owners and document status. [1]
If you meant “patent loratadine” for a specific product (brand or formulation), what details should you provide?
To pinpoint the correct patents, it helps to know:
- Country/region (US, EU, UK, etc.)
- Brand name (if any) and dosage form (tablet, syrup, ODT, etc.)
- Strength (mg) and route (oral)
- Whether you care about the drug substance or a specific formulation
If you share those details, I can help interpret which patents are most likely relevant based on the available patent-tracking information. [1]
