ANVISA: Version 2 of the CADIFA Manual for APIs available

Both a valid CADIFA and a GMP certificate, are necessary for the approval of an associated marketing authorization or post-approval change application.

In general, the manual is structured in six main chapters and twelve annexes, including a document history as well as a list of abbreviations. The main chapters are named as listed below:
