This profile sets minimum expectations for a Medication resource to record, search, and fetch medications associated with a patient. It is based on the [AU Base Medication](http://build.fhir.org/ig/hl7au/au-fhir-base/StructureDefinition-au-medication.html) profile and identifies the **additional** mandatory core elements, extensions, vocabularies and value sets that **SHALL** be present in the Medication when conforming to this profile. It provides the floor for standards development for specific uses cases in an Australian context. 
In AU Core a Medication resource is used within the context of a referencing resource: MedicationAdministration, MedicationDispense, MedicationRequest, or MedicationStatement resource. 

See [Comparison with other national and international IGs](comparison.md) for a comparison between AU Core profiles and profiles in other implementation guides.

### Usage Scenarios

The following are supported usage scenarios for this profile:

* Query medications associated with a patient referenced by another resource
* Record or update a medication associated with a patient referenced by another resource
* Read medications associated with a patient referenced by another resource

### Profile Specific Implementation Guidance

* See the [Medicine Information](medicine-information.md) page for guidance on how medicinal product identification can be structured in FHIR conformant to AU Core.

**Usages:**

* Refer to this Profile: [AU Core MedicationRequest](StructureDefinition-au-core-medicationrequest.md) and [AU Core MedicationStatement](StructureDefinition-au-core-medicationstatement.md)
* Examples for this Profile: [Medication/1active-ingredient](Medication-1active-ingredient.md), [Medication/2active-ingredients](Medication-2active-ingredients.md) and [Medication/simvastatin](Medication-simvastatin.md)
* CapabilityStatements using this Profile: [AU Core Requester CapabilityStatement](CapabilityStatement-au-core-requester.md) and [AU Core Responder CapabilityStatement](CapabilityStatement-au-core-responder.md)
