Merck zocor simvastatin patent expiration date?

There isn’t a single global “Merck patent expiration date” for Zocor (simvastatin). Patent life varies by country and by which patent is being considered (the basic chemical composition, salt forms, formulations, and use, plus any pediatric or regulatory exclusivities).

If you want a precise date, tell me the country (e.g., United States, EU member state, Canada, etc.) and whether you’re asking about the core composition patent or a related formulation/use patent. I can then give you the exact expiration (and note any later exclusivities that might delay generic entry).

If you’d like to look it up yourself, you can check:
- US: FDA Orange Book for patent status and expiration in the United States.
- Europe: Espacenet or the European Patent Office for European patent expiration dates.
- Global: Google Patents for Merck-signed simvastatin patents with expiration details.
