# Pipeworx Orange Book rows carry a per-product `approval_date` that can be a later supplement date, not the drug's original approval

**This is an observation of how two of our own house tools (`orange_book_application_detail` and
`fda_drug_approvals`) expose the same FDA application differently**, not a claim about any drug's
approval history.

## Claim
`orange_book_application_detail`'s product rows are one row per NDA *product number*, each stamped
with that product's own `approval_date` — which, for a product number added later via a supplement
(e.g. a new dosage form), is the supplement's approval date, not the NDA's original approval. A
caller reading the first product row's `approval_date` as "when this drug was approved" can be off
by over a decade. `fda_drug_approvals`, querying the same application, correctly separates this out
as `original_approval_date` at the top level with each `submissions[]` entry (`ORIG` vs `SUPPL`)
dated individually.

## How observed
Re-observed live, 2026-10-08T17:34:12Z–17:35:30Z:
- `orange_book_application_detail({"application_number":"202155"})` (Eliquis/apixaban NDA) returned
  three product rows: product `003` (`TABLET, FOR SUSPENSION`, 0.5MG) with `"approval_date":
  "2025-04-17"`; products `001`/`002` (the original tablets) with `"approval_date":"2012-12-28"`.
  Product `003` sorts first in the array.
- `fda_drug_approvals({"query":"products.active_ingredients.name:\"APIXABAN\"",
  "sort":"approval_date_asc"})` for the same `NDA202155` returned `"original_approval_date":
  "2012-12-28"` at the application level, and its `submissions[]` array shows `SUPPL 39` and
  `SUPPL 40` both dated `2025-04-17`, class `"Efficacy"` — the oral-suspension line extension that
  created product `003`.
- Confirms the same discrepancy flagged in the earlier same-day run (`run-pharma-2026-10-08.yaml`,
  step `resolve.apixaban.problems[1]`), independently reproduced here via a direct second tool
  (`fda_drug_approvals`) rather than re-reading the same Orange Book row.

## Applies to
Any multi-product NDA where a later product number was added by supplement (new strength, dosage
form, or route) after the original approval — `orange_book_application_detail`'s per-row
`approval_date` is correct for that row's own history, but a caller treating any one row as "the"
approval date for the whole NDA, especially when product rows are not returned in product-number
order, will read the wrong year. `fda_drug_approvals`'s `original_approval_date` field is the
tool that actually answers "when was this NDA first approved."
