For different reasons, the manufacture of APIs may sometimes require adding excipients. In the context of an authorisation procedure, this practice reveals to be problematic. Read more here about the data required for the quality documentation of a API mix in an ASMF or a CEP.

The manufacture of APIs sometimes requires adding of one or several excipients like for example an antioxidant or an inert matrix for stabilisation purposes. Occasionally, corresponding mixtures can be manufactured to optimize workability for further processing or filling (e.g. improvement of flowability). Yet, within a marketing authorisation procedure, such an API mix can possibly be accepted differently than the pure API.
