# ELEMENT Constrained Domain Model: MedicinalProductOrSubstance
An ELEMENT to represent the medicinal product or substance prescribed, non-prescribed, administered, or dispensed. The class includes any pharmaceutical or biologic product including DM+D concepts for VMP/AMP, VMPP/AMPP, and VTM but is not restricted to it. Non DM+D concepts may also be represented. The medicinal product may optionally include the dose form which is the description of the presentation of a medicine e.g. tablet, injection, suspension etc. [ePS]. A prescribed, non-prescribed (e.g. ‘over the counter’) or recommended medication taken or to be taken by the patient. Typically, the medicinal product name takes the form which includes the medicinal name + strength + form + unit dose. The product may also include the device used for administration. ## Specializes ## ProductOrSubstance ## Attributes
Name | Data type | Occurs | Description | Value constraints
--- | --- | --- | --- | ---
name | SC | 1..1 | The name, expressed as a coded value or as plain text, specifies the clinical or administrative concept to which this EHR node corresponds, as labelled in the EHR system in which it was first committed. |
archetype_id | ST | 0..1 | The unique identifier of the archetype node to which this RECORD_COMPONENT corresponds, either in the EHR Provider system or as a mapping produced when this EHR_EXTRACT was created. The syntax for populating this attribute value is defined in EN 13606-2:2008. Within the LRA the value assigned to this attribute SHALL have no effect on the interpretation of instances of this class and the attribute SHALL not be used as a predicate for semantic data retrieval. |
rc_id | II.Uuid | 1..1 | The globally-unique identifier by which this node in the EHR hierarchy is referenced in the EHR system to which the data were first committed. This identifier shall be retained by the EHR Recipient and re-used whenever this RECORD_COMPONENT is subsequently included in another EHR_EXTRACT. |
meaning | CD.CV.SCT | 1..1 | A coded representation of the primary semantically processable meaning conveyed by the ELEMENT. Contains a SNOMED CT expression representing the nature of the physical entity. |
code
Semantic expression constraint
synthesised | BL | 1..1 | This attribute value shall be TRUE if this RECORD_COMPONENT has been created in order to comply with this standard, but this point in the EHR hierarchy has no corresponding node in the EHR from which it was extracted. Within the LRA this attribute is used to indicate a RECORD_COMPONENT instance that has been derived in some way from a pre-existing RECORD_COMPONENT. |
policy_ids | II | 0..* | This attribute identifies one or more access control policies that specifically pertain to this RECORD_COMPONENT and which need to be communicated to the EHR Recipient to govern future access to it. The identifiers may refer to policy information included in this EHR_EXTRACT as defined in EN 13606-4:2007, or to policies held in external policy servers to which the EHR Recipient has access. |
sensitivity | INT | 0..1 | The sensitivity of this RECORD_COMPONENT, represented using the code set for this attribute defined in EN 13606-4:2007. |
orig_parent_ref | II | 0..1 | The identity of the RECORD_COMPONENT that is the original parent (context) for this RECORD_COMPONENT, to be present if this information has been copied from another part of the EHR of this subject of care. |
value | QTY | 1..1 | The amount of the ingredient substance present in the whole. |
