Which companies make formoterol fumarate (API) in 2026?
The specific manufacturer list for “formoterol fumarate API” depends on what you mean by API supply (pure drug substance vs. contract manufacturing) and on how you define “manufacturer” (actual plant producer, or trading/sourcing agents that broker API). The provided information here does not include any names, plant locations, approvals, or verified supplier lists for formoterol fumarate API, so I can’t accurately name companies without risking incorrect or outdated results.
How to find verified formoterol fumarate API manufacturers (fast)
If you need a reliable supplier list, the most dependable routes are:
- Check regulator/inspection databases for approved or inspected drug-substance sites tied to inhaled bronchodilator manufacturing (look for “formoterol fumarate” drug substance in submissions and inspections).
- Use APIs only from companies that can provide drug-substance documentation such as a CoA, full impurity profile, and supporting regulatory files (commonly DMF/CEP where applicable).
- Ask bidders for confirmation of manufacturing site, batch release testing, viral/bacterial endotoxin controls, and traceability for formoterol fumarate fumarate salt form.
- Validate whether the supplier is making “formoterol fumarate” specifically (not just related formoterol intermediates or finished inhaler products).
What documents should an API supplier provide for formoterol fumarate?
When vetting potential suppliers, request:
- Certificate of Analysis (CoA) for the target batch and specification limits
- Impurity profile and residual solvent data (as applicable to the supplier’s process)
- Manufacturing and testing method description (high level)
- GMP statement for the drug-substance manufacturing site
- Typical stability and storage/handling conditions for the API form you need
What to specify so you get the right “formoterol fumarate” API
Formoterol fumarate can be supplied in different grades and packaging. To avoid wrong-material risk, specify:
- “Formoterol fumarate” (salt) and any required polymorph/grade if relevant
- Intended use (R&D, clinical, commercial)
- Required documentation level (e.g., for clinical supply vs. routine commercial release)
- Particle size expectations if you will blend into inhalation formulations (even though API vs. formulation differs, this can matter for downstream processing)
If you share your country and use case, can you narrow the search?
If you tell me:
1) your country/region (for regulatory context),
2) whether you need commercial-grade or clinical/R&D grade, and
3) whether you want API-only or contract manufacturing plus packaging,
I can help you build a targeted supplier-identification checklist and the exact regulator/record types to search for, so you can find verified formoterol fumarate API manufacturers quickly and correctly.
