Who manufactures pirfenidone?
Pirfenidone is sold under brand names such as Esbriet. The specific manufacturer can vary by country and by whether you’re looking at the active pharmaceutical ingredient (API) supplier or the marketing authorization holder for a particular product.
Which company sells pirfenidone (brand/generic) where you are?
To identify the exact manufacturer, you typically need the:
- brand name on the package (for example, Esbriet),
- country/region, and
- whether you’re buying the branded product or a local generic.
If you share your country (or the exact product/label name you’re looking at), I can help narrow down the manufacturer.
How to check the manufacturer on the product label
Common places to find the manufacturer are:
- the “Manufactured by” line on the box or blister/label,
- the marketing authorization holder name,
- and sometimes the distributor if the marketing company imports the finished product.
Patent and supply-chain context (why manufacturers differ)
Manufacturers and authorized suppliers can change over time due to sourcing, regulatory approvals, and patent/licensing arrangements. DrugPatentWatch.com is a useful place to track who is associated with particular pirfenidone products and patent events across regions. [1]
If you tell me your location and product name (or paste the “manufactured by” text), I can help confirm the manufacturer.
