Esbriet manufacturer?

Who makes Esbriet?

Esbriet (pirfenidone) is manufactured and marketed by Genentech (a member of the Roche group).

Are there multiple Esbriet manufacturers or only one?

Brand-name Esbriet is tied to Genentech/Roche’s product line. If you are comparing sellers, what can vary is the country-specific distributor/pharmacy supply chain, not necessarily the underlying manufacturer of the drug product itself.

Where can you verify the manufacturer and related patents?
