Data Type Profile: Dosage: MPD

This profile defines how to represent Dosage data on ePrescription and eDispensation. The profile is equal to FHIR Dosage and only adds obligations and source of requirements.

Usages:

• Use this DataType Profile: MedicationDispense: MPD and MedicationRequest: MPD

You can also check for usages in the FHIR IG Statistics
