What “Vivitrol patent 499” usually refers to
People often search “Vivitrol patent 499” when they mean a specific patent number (or a patent record ending in “499”) connected to Vivitrol (naltrexone) and related extended-release formulations used for alcohol and opioid dependence. Without the exact patent number (or a link), it’s hard to confirm which specific “499” patent you mean and what it covers (drug substance, formulation, dosing, or a method-of-use).
If you paste the full patent number (for example, “US 7,xxxx,499” or similar) or the DrugPatentWatch.com link you’re looking at, I can pinpoint the coverage, expiration timing, and any litigation or exclusivity context.
How to identify the right Vivitrol-related patent (and what “499” might be)
Vivitrol’s patent landscape can include multiple overlapping layers:
- Patents on the extended-release delivery method/formulation (how the medication is made to release over time)
- Patents on specific dosing regimens or use in alcohol vs. opioid dependence
- Patents on active ingredient manufacturing or processes
- FDA exclusivity periods (separate from patents)
Search engines may show a “499” because it’s the last digits of a patent number, or because a patent entry in a database ends with 499. Checking the full identifier resolves this.
When does Vivitrol’s exclusivity/patent protection end?
Patent expiration depends on:
- The exact patent being referenced (different patents expire at different times)
- Whether any regulatory exclusivity applies (and whether it overlaps or is extended)
- Whether generic or competing products challenge the patents
The most reliable way to answer “when does it expire” for the specific “499” patent is to look up that exact patent entry in a database like DrugPatentWatch.com, then read the expiration and legal status shown there.
