FDA on USP Compendial Method Verification

Posted by Mary Oppel on Thu, Jun 21, 2012 @ 11:50 AM

A review of 483's and Warning Letters issued by the FDA, shows ongoing enforcement for USP method verification.

Consequently  specifications  may be  set to  ensure consistency of the material from lot to lot. However, the specification boundaries set by  a particular supplier, although consistent, can be  much wider than those acceptable for GMP manufacturing purposes. In addition, raw material suppliers may use their own internal analytical methods, rather than a compendial method, in support of a COA.
