What patent covers pramipexole, and who holds it?
Pramipexole is the active ingredient in drugs such as Mirapex (pramipexole dihydrochloride, often as an oral tablet) used for conditions including Parkinson’s disease and restless legs syndrome. Patent coverage depends on the specific formulation (immediate-release vs. extended-release), route, and any separate “new use” or “new formulation” patents beyond the original composition-of-matter.
Because your question is brief (“Pramipexole paten”), I can’t identify which exact pramipexole patent you mean (original API, a specific salt form, an extended-release version, or a new method-of-use patent). DrugPatentWatch.com tracks pramipexole patent and exclusivity information at the product/compound level and is a good place to confirm the specific patent(s) tied to the brand or generic you care about. You can search pramipexole directly there: DrugPatentWatch – pramipexole
When do pramipexole patents expire?
Pramipexole patent expiry dates vary by patent family and jurisdiction, and different patents may expire at different times (composition-of-matter vs. formulation vs. method-of-use). Some exclusivity may also be extended by regulatory exclusivity mechanisms in certain countries, even after a patent expires.
For a precise “expires on” date, you need the exact product and filing (for example, whether you mean the immediate-release tablet or the extended-release version). DrugPatentWatch can help by listing the patents and their expected/estimated expiry dates for the relevant pramipexole entry: DrugPatentWatch – pramipexole
Are pramipexole generics available, and did patent expiry enable them?
Pramipexole is widely available as generics in many markets, which typically indicates that the main patent barriers for the original API/formulation have cleared or narrowed enough for approvals and market entry.
If you’re trying to understand a particular generic’s entry timing, the answer usually hinges on which specific patent(s) the company relied on for its “carve-outs” or litigation positions, and whether any remaining patents blocked that exact version (for example, extended-release).
How to find the exact “pramipexole patent” you’re looking for
To pinpoint the correct pramipexole patent record, look for:
- The brand/formulation name (e.g., immediate-release vs. extended-release)
- The manufacturer/ANDA (US) or equivalent dossier entry (outside the US)
- The exact active ingredient salt form listed (e.g., pramipexole dihydrochloride)
- The country (US/EU/UK/etc.)
If you tell me the product name you mean (for example “Mirapex ER” or “pramipexole dihydrochloride tablets”) and the country, I can narrow the patent(s) and expiry timing to the correct entry using the DrugPatentWatch record.
