VALIDATION & CALIBRATION

History

Drug product quality was seen as the function of the status of the product itself.

Flawed approach- destructive tests-individual products can not be tested.

No statistical method was available to ensure quality of a batch of drug.

US FDA included some form of validation around mid 1970s (Process validation 21 CFR parts 210 and 211)

Initially limited to sterile products and later extended to other dosage forms

This was out of a concern to develop a verification mechanism that would need to be applied to the process to be meaningfully extrapolated to an entire batch

Followed by those requiring WHO GMP Certification for COPP.

Now included in the revised schedule M
