This profile defines a medication structure that localises core concepts, including terminology, for use in an Australian context. The purpose of this profile is to provide national level agreement on core localised concepts. This profile does not force conformance to core localised concepts. It enables implementers and modellers to make their own rules, i.e. profiling, about how to support these concepts for specific implementation needs.

### Usage Notes

Profile specific implementation guidance:

- Medication definition includes coding as:
  - PBS Item Code - Pharmaceutical Benefits Scheme coding, claiming context is not relevant as medicine coding
  - Medication Package Global Trade Item Number - Global Trade Item Number (GTIN) physical product reference
  - AMT Medicines - Australian Medicines Terminology, national drug terminology
  - MIMS Package - commonly used medicine coding
- When a code for medication definition is unavailable, just text is allowed in `Medication.code.text`.
- When a medication is compounded and is a list of ingredients, `Medication.code` may contain only the list of ingredients as text in `Medication.code.text`.
- For support as text representation of other medicinal product information consider:
  - ​brand name in Medication Brand Name extension
  - ​generic name in Medication Generic Name extension
  - medication strength, for medication as a whole, in Medication Strength extension
  - medication form in `Medication.form.text`
  - item form and strength as part of medication definition in `Medication.code.text`
  - manufacturer in `Medication.manufacturer.display`
  - When individual ingredient strength is unavailable as a ratio, it can be surfaced as text in `CodeableConcept.text` by using pre-adoption of the FHIR R5 `Medication.ingredient.strength[x]` element with the extension URL http://hl7.org/fhir/5.0/StructureDefinition/extension-Medication.ingredient.strength[x]. See this example of use Tadim.
    - This is to be interpreted as the strength of that specific ingredient, not the strength of the medication as a whole.
    - Where possible use the existing `Medication.ingredient.strength` element in preference to pre-adopting the FHIR R5 `Medication.ingredient.strength[x]` element.
    - Details on cross version pre-adoption implementation can be found in the FHIR specification Extensions for converting between versions section.

Potentially useful extensions:

- Medication: Medication Brand Name
- Medication: Medication Generic Name
- Medication: Medication Strength
