description: This profile sets minimum expectations for a Medication resource in the context of a patient summary in an Australian context. It is based on the [AU Base Medication](http://build.fhir.org/ig/hl7au/au-fhir-base/StructureDefinition-au-medication.html) profile, and applies the constraints of [AU Core Medication](http://hl7.org.au/fhir/core/StructureDefinition/au-core-medication) and [Medication (IPS)](http://hl7.org/fhir/uv/ips/StructureDefinition/Medication-uv-ips).
