- The line under the title explains in plain words what this item is for. The coloured label beside its status gives its Category, its main subject, and Sub Category, the type of document, in the same colours as the maps.
- Status comes from the latest dated event below, and each event links to its source.
- Lifecycle shows the steps so far, then any expected target. Targets are not facts.
- In plain English is our own summary, not the official text. Where we have read the document in detail, a fuller profile follows, with its context, scope, contents and key points.
- Related shows links to other documents. Select Compare to see two side by side.
Lifecycle
Solid steps have happened. A dashed step is expected, and it is not a fact. Only dated steps in our record appear here.

Context and history
FDA issued this warning letter to Sanitor Corporation on 29 Nov 2021. It concerns finished drugs, and it is listed here because of what it says about computerised systems or data integrity. FDA warning letters are public, and this one names the firm. It concerns one firm at one point in time, and it says nothing about the firm today or about other firms.
Who and what it applies to
This one firm. It is a record of enforcement, not guidance for everyone.
What it contains
- Quality unit
- The unit did not meet its responsibilities.
- Laboratory controls
- Specifications, standards and test procedures were not adequate.
- Computer controls
- The FTIR system could not prevent deletion of raw data.
Key points
- A system change alone is not enough: FDA also asked for a retrospective review.
- It binds one firm, and it shows how FDA applies existing rules.
In practice
General reading, not advice. This is drafted with AI and may not fit your situation. It does not replace the official text, your own quality system or qualified advice, and an inspector may take a different view.
- After fixing a control, assess past data as well.
