Resource Profile: EPA Pharmaceutical Product Medication

Defines the medication resource for a component of a ‘Kombipackung’ for the Medication Service in the ePA system. These profiles are intended to inherit from EPAMedication, but due to tooling issues, this inheritance cannot currently be implemented.

Usage:

• Use this Resource Profile: EPA Medication
