How this service works
FDA Purple Book licensed biological products matching a name (brand or proper name, e.g. adalimumab): applicant, BLA number, license type (351(a) originator, 351(k) biosimilar or interchangeable), strength, dosage form, route, marketing status, approval date, reference product and exclusivity expiry dates, plus the products newly approved or updated this month. From FDA's monthly Purple Book data download.
Output
Returns a list of matched biological products from the FDA Purple Book, each with fields including applicant name, BLA number, license type (351(a) originator or 351(k) biosimilar/interchangeable), strength, dosage form, route of administration, marketing status, approval date, reference product, and exclusivity expiry dates. Also flags any products newly approved or updated in the current month.
Example use cases
Verify biosimilar status before formulary decision
“I need to check the FDA Purple Book for bevacizumab — can you pull up all approved biosimilars and interchangeable versions, including their BLA numbers, license types, and approval dates?”
Check new biologic approvals this month
“What biological products were newly approved or updated in the FDA Purple Book this month? Pull up to 50 results so I can see the full list.”
Confirm originator exclusivity expiry for a biologic
“Look up trastuzumab in the FDA Purple Book and tell me the reference product, exclusivity expiry dates, and whether any products are licensed as interchangeable biosimilars under 351(k).”
Technical details
Endpoint
GEThttps://api.healthtravel-api.workers.dev/api/health/fda-purple-book?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need authoritative FDA regulatory data on licensed biological products — especially to determine biosimilar or interchangeable status, BLA number, exclusivity periods, or approval history. Prefer this over general drug databases when the regulatory licensing classification (351(a) vs 351(k)) or Purple Book-specific fields like exclusivity expiry are required.
Side effects
- No results returned if the name or BLA number does not match any Purple Book entry
- Misspelled or unofficial names may return empty results
- Monthly data download may lag real-time FDA approvals by days or weeks
- Limit parameter out of range (e.g. >100) may cause an error or be clamped
- Ambiguous names shared by multiple products may return a large set requiring filtering
