Who are the key “suppliers” in the Mydayis chain?
In pharmaceutical supply chains, “supplier” most often maps to (1) the marketing/brand authorization holder, (2) the manufacturer(s) listed for drug product, and (3) distribution/labeling entities. For Mydayis, the labeling ties the brand to Takeda in U.S. commercialization.
1) Brand authorization and U.S. commercialization supplier
- Takeda Pharmaceuticals U.S.A., Inc. (U.S. marketing party listed in prescribing information) [1].
2) Brand company listed on the U.S. product label
- Alexza Pharmaceuticals (listed on prescribing information as the brand-related company) [1].
What manufacturing entities are listed for Mydayis on the label?
The prescribing information for Mydayis identifies:
- A U.S. commercial/labeling party (Takeda) and the brand company (Alexza) [1].
Manufacturing-site level identification (drug substance and finished dosage plant)
The specific finished dosage manufacturer name(s) and sites are typically listed in the prescribing information under sections like “Manufactured for” or “Manufactured by,” and sometimes in the package labeling. That exact “manufacturer of record” and the site-level address details are required to name the true finished-goods supplier(s) precisely.
This response is limited to what the provided sources support. It does not include plant-level manufacturer names beyond what the Mydayis labeling explicitly ties to the brand and U.S. marketing chain in the cited source.
