Why a buyer runs it

Catch enforcement before it hits your supply.

Plant-level enforcement watch.

Every FDA enforcement event resolved to the plant entity. Match to your supplier list and get notified on new findings.

Three-tier event taxonomy.

Warning letter, untitled letter, and import alert are distinct enforcement tools. The feed labels each so the response can match the severity.

Half-life signal.

Historical median time-to-resolution per plant is computed across the catalog. A warning letter resolves on average in roughly seven months; deviations from that get flagged.

Live, not archived.

Catalog refreshes weekly. New letters appear within days of FDA publication; the brief carries the publication date and the URL of the official FDA letter.

The FDA published eight pharmaceutical warning letters in the trailing 60 days. Three matter to a typical generics buyer: Flowchem (Indian API plant, CGMP / API adulteration), Yangzhou H&R (Chinese finished-pharma plant), and the broader cluster of US compounding sites. None of these are on your watchlist; the closest match was Medical Products Laboratories which shares an ANDA reference with two of your filing partners but is not a current supplier.

The warning-letter monitor is the continuous compliance signal on top of the 483 feed. PharmaDB joins enforcement events to the plant catalog, resolves them to a buyer’s supplier list, and surfaces matches as the FDA publishes. The view is compliance_events; the join is to plants. Refresh cadence is weekly.

FAQ

Frequently asked

What is the difference between a warning letter, untitled letter, and import alert?+

A warning letter is the FDA's strongest pre-litigation enforcement tool — it cites specific violations and demands corrective action. An untitled letter is less severe and used for issues that don't warrant a warning letter. An import alert (66-40 / 66-41 / others) directs FDA field staff to detain products at the border without inspection. All three are tracked separately.

How fast does a new letter appear in the feed?+

The FDA publishes warning letters on its public site after a several-week internal review. PharmaDB pulls the publication feed weekly, so a published letter typically appears within seven days of FDA publication. The catalog row carries both the issue date and the publication date.

How long does an import alert stay active?+

Until the plant successfully petitions for removal. The catalog tracks the active import-alert list; when a plant is delisted, its status flips to inactive on the next refresh. Historical median active time is roughly two years across the dataset, but the variance is wide.

What is the warning-letter recovery half-life?+

Median time from a warning letter to a subsequent NAI inspection at the same plant, across the entire historical dataset, is roughly 223 days. PharmaDB surfaces it as an empirical reserve-sizing input — useful for finance modeling supply risk and for BD timing on distressed-asset conversations.

Are non-FDA enforcement events covered?+

The companion analysis covers EMA non-compliance reports, MHRA inspection failures, EDQM CEP suspensions, and WHO PQ withdrawals. Cross-regulator enforcement views surface as a separate compliance dossier.

Does the feed cover compounding plants and OTC manufacturers?+

Yes — the source taxonomy is the FDA's. CGMP letters issued to compounding pharmacies, OTC manufacturers, and contract manufacturers all surface. The brief notes the FDA programme so a buyer can filter to API-relevant matches.
