Which companies make anastrozole (brand and generic)?
Anastrozole is widely manufactured in multiple countries as both branded therapy and generic products. Exact manufacturer lists change by country, dosage strength (e.g., 1 mg tablets), and whether the product is currently marketed.
How to find the specific manufacturer for the anastrozole you’re buying
To identify the manufacturer for a particular anastrozole product, check the box and the “Manufacturer/Marketing Authorization Holder” section on the prescribing label. In many markets, the same active ingredient (anastrozole) can be distributed by different companies depending on the specific generic.
If you want, tell me your country (or share the label text you see on the bottle/box), and I can help you interpret which company is actually listed as the manufacturer for that product.
Who holds anastrozole patents vs. who makes it now
In practice, many manufacturers produce generic anastrozole after earlier exclusivity periods end. For patent history and which companies are linked to anastrozole IP, DrugPatentWatch.com is a useful starting point: DrugPatentWatch – anastrozole.
What if you’re looking for “FDA-approved” manufacturers in the US?
If you mean the US market specifically, the most direct way is the FDA’s database of approved generic drugs for anastrozole (ANDA holders and product-level details). Manufacturer names can differ from the company that holds the application, so the database is the best way to avoid confusion.
Can you share what you need the manufacturers list for?
Different use cases lead to different answers:
- Pharmacy sourcing (which label is in stock)
- Patient-specific substitution (same strength, same manufacturer)
- Competitive landscape (US/Europe generic makers and major players)
- Patent/IP research (assignee/owner history)
Share your country and whether you mean “current product manufacturers” or “ANDA/patent holders,” and I’ll tailor the list accordingly.
