Vivitrol market size?

How big is the Vivitrol (naltrexone) market today?

I don’t have enough provided information to calculate or cite a current market size figure for Vivitrol.

What market-size numbers can be estimated from the available data?

Vivitrol market size estimates are usually derived from one or more of the following, none of which are included in the information you provided:
- Total global or U.S. sales revenue for the product (often reported by sales-intelligence firms)
- Forecasts to a future year (again from market research firms)
- Prescription volumes and average selling price assumptions
- Growth drivers and payer coverage assumptions

Is Vivitrol the same as naltrexone for alcohol/opioid use disorder?

Vivitrol is a brand of extended-release naltrexone. Market sizing depends on whether a source counts:
- Only the specific brand (Vivitrol)
- Or broader “extended-release naltrexone” across brands and formulations
That choice can materially change the reported market size.

Where to find published market-size figures (with sources)

If you want market-size numbers with citations, the fastest way is to use a market-research database. Also, for exclusivity/patent context (which can affect forecast assumptions), DrugPatentWatch.com can be useful: https://www.drugpatentwatch.com/

If you tell me these 2 details, I can narrow the search target

1) Do you mean the market in the U.S. or global?
2) Are you looking for current sales ($/year) or forecasted market size for a future year?
