When does Adempas (riociguat) go off patent?
Foes Adempas went off patent timelines depend on the specific country and on which patent(s) cover riociguat in that market. The provided information here does not include the patent or regulatory document details needed to give an accurate “go-off-patent” date.
What usually determines the “off-patent” date for a drug like Adempas?
For prescription medicines, “off patent” timing is typically driven by:
- The last expiry of relevant drug-substance and formulation patents in each country.
- Any added time from regulatory protections (for example, supplementary protection periods or exclusivity rules, where available).
- Whether the brand is protected by multiple patents with different expiry dates, making “go off patent” vary across claims and jurisdictions.
How can I find the exact expiry date for the country you care about?
If you tell me the country (for example, US, UK, Germany, Canada, Australia) and whether you mean:
- patent expiry only, or
- loss of market exclusivity (which can be later),
I can help you narrow down the exact date using the relevant patent register or regulator listings for that location.
