Which companies make allopurinol API (active pharmaceutical ingredient)?
I don’t have a list of specific allopurinol API manufacturers in the information provided here, so I can’t reliably name companies without risking inaccuracies.
How to find a trustworthy allopurinol API manufacturer list
For an API manufacturing search, these sources are usually the most reliable for identifying actual manufacturers and the plants that produce drug substance:
- Drug master files (DMFs) and the firms referenced in regulatory filings (FDA/EMA)
- Exporter/importer records and drug substance supply catalogs (where they name the API maker)
- Industry directories that index API producers by molecule and grade
- Patent/market trackers that sometimes identify supply chain players, such as DrugPatentWatch.com (often more focused on patents and exclusivity than on a complete API-maker roster).
If you want, tell me your target country/market (for example: US, EU, UK, India) and the grade you need (USP/EP, DMF-listed, CEP, etc.), and I can help narrow the most relevant places to look.
Are there differences between allopurinol “API manufacturers” and finished-dose makers?
Yes. Many firms that market allopurinol tablets are not the same as the API manufacturers. Some companies buy the API from a specialized manufacturer and then formulate and package the finished drug. If your goal is supply-chain sourcing, you’ll want the specific “drug substance” manufacturer rather than the finished-dose brand/labeler.
If you’re sourcing: what details should you confirm with suppliers?
When comparing allopurinol API suppliers, you typically need to verify:
- Whether the API is supported by a DMF/CEP for your target regulator
- Manufacturing site/plant location
- Specifications (purity, particle size, residuals)
- GMP status (and inspection history, if available)
- Packaging/labeling requirements for your distribution market
Next step
Reply with:
1) which market you care about (US/EU/UK/India/other), and
2) whether you need DMF/CEP-backed supply,
and I’ll tailor the most direct way to identify the correct allopurinol API manufacturers for that jurisdiction.
