Definition
The representation of a medicinal product as it is supplied in a package by a by a single organisation (manufacturer or supplier) in a single jurisdiction under a single name (which may be a trade or brand name) for placement into the supply chain. It is a subtype a subtype of, and real world equivalent to, the Packaged Clinical Drug (PCD) class described above.
Use
...
Cases
The following use cases are supported by the Real Packaged Clinical Drug concept class:
- Describing medication process activities: prescribing, dispensing, administration and medication statements; of these, dispensing and administration will use this concept when it is available to clearly state which actual packaged product (or content from it) was used/supplied to the patient (with batch/lot and expiry information if required, either manually or by automatic identification and data capture (AIDC) - , for example, scanning the bar code on the package)
- Compliance monitoring, using pack size information to calculate whether a patient is following the dosage instructions correctly (how quickly a repeat supply of a package of medication is required)
- Anti-counterfeiting: in support of initiatives such as the Falsified Medicines Directive (see amended Directive 2001/83/EC) using AIDC and which requires scanning of medicines at the point of supply (to the patient)
- Reimbursement: national or local systems may set pricing or eligibility against actual packaged products
- Pharmacovigilance – especially for product defects and labelling labeling issues
- The association between the clinical representation of medicinal products and their representation in the supply chain for supply chain management
Discussion
The real packaged clinical drug represents the product as its packaged products that are marketed into the supply chain in any jurisdiction. A small number of regulatory authorities license medicines at this level, with each package having a separate authorisation, ; others allow all the different package sizes to be authorised in by the single authorisation of the RCD. Real packaged clinical drugs must be represented using the closed world view; they contain they contain only the content as stated in the logical definition. Since this class represents real product packages as authorised in a jurisdiction, description of additional non-defining information, such as excipient substances (flavours, preservatives, sweeteners, etc.) or details about the product name parts or product authorisation information and product availability information can be attached to real packaged clinical drug concepts, should a national extension wish to do this.
The real The real clinical packaged drug is the marketed (therefore therefore "real") instantiation in any one country of the abstract packaged clinical drug in the international edition, and as such, real packaged clinical drugs classify as child concepts of the packaged clinical drug, if the national extension has authored these concepts..
As described above in the PCD section, this national extension model does not represent intermediate layers of packaging; it represents only the outer package used in the supply chain.
National extensions that require real packaged clinical drug concepts can are advised to define their RPCD real packaged clinical drug concepts using real clinical drug concepts from their national extension or, if only real packaged clinical drug concepts are authored without RCDs, using clinical drugs from the international edition or national extension. However, if real packaged clinical drug concepts are authored without RCDs, there is little opportunity for This allows grouping of concepts on the right-hand/real side of the model; although real packaged clinical drug concepts with the same product name and supplier would have the required attributes to group them together, there is no parent grouper concept to place them under, so the grouping would be hard to show. If real packaged clinical drug concepts without RCDs and without PCDs, then the stated and inferred views will be equivalent, there will be no grouping concepts for the real packaged clinical drug concepts to be associated with.package concepts with their associated real clinical drug using the

Attributes
The following table describes the attributes for real packaged clinical drugs (RPCDs) that contain one type of clinical drug only. That is, they are NOT combination (multi-component or kit) products.
The real The real packaged clinical drugs class is related to the real clinical drug class by a composition relationship relationship, and therefore the attribute "contains |Contains real clinical drug " (attribute)| is used to make the association between the real the real packaged clinical drug and the (real) clinical drug it contains.
Representation of real packaged medicinal products should use presentation strength (either only, or in addition to, concentration strength) whenever possible in order to be able to accurately describe the number of presentation units present in the package. The exception will be is for continuous products such as semi-solid dose forms of creams, gels, etc. where strength pattern 3a is used (see international Editorial Guidelines International Medicinal Product Model). In all cases, the pack size and pack size unit should relate to the denominator unit of the strength.

Optional Additional Information
The following information may be additionally used to describe the Real Packaged Clinical Drug concept in a national extension. With the exception of container information, the attribute concepts and values to populate these, if this data is to be held in a structured form, would need to be authored into the extension using reference sets.
Optional Additional Information
As with the real clinical drugs, national extensions may require additional information to be associated with real packaged clinical drugs. This may include characteristics of the packaged product that can be described within the SNOMED CT structure using attributes and values, managed alongside the SNOMED CT structure (e.g., in a reference set) and/or relationships between identification systems should be managed in cross maps.
- Packaged product characteristics may include package/container types Package/container type (e.g. bottle, box, jar, tube ); some use cases may also require information about sterile wrapping of some medicinal product packaging
- License information - for those jurisdictions that license at a package level rather than at the real clinical drug level
- License identification ("authorisation number")
- Licensing class and/or legal status of supply
- Usage information (prescribability within a particular jurisdictional context) including legal status
- Reimbursement information
- Administration - to support various use cases including robotic dispensing) and administration device supplied in the package (e.g. medicine spoon, vaginal applicator, applicator brush for cutaneous liquid products)
- Knowledge about the product may include usage information such as availability within the supply chain, licensing/authorization category and/or legal status of supply, and prescribability information including reimbursement categories
- Other identification systems for a real packaged clinical drug may include licensing/authorization number, if this is provided for individual packages or Global Trade Identification Number
In jurisdictions where repackaging and/or parallel importing are authorised, a national extension may wish to consider having a relationship between the repackaged or parallel imported real packaged clinical drug and the real clinical drug supplied by the original manufacturer, if that is present within the jurisdiction.
IDMP Compatibility
This concept as defined is equivalent to the Packaged Medicinal Product of ISO 11615, which in that standard is identified by a PCID. As the representation of the "real world product " authorised for sale and/or supply that exists for all jurisdictions and which is marketed into the supply chain for use, it is the concept that should form the 1:1 join between representation in the regulatory domain (IDMP) and representation in the clinical domain (SNOMED CT and national medicinal product terminologies), even if some national medicinal product terminologies choose not to represent it, but only an abstraction of it (i.e., the Real Clinical Drug class of concepts).
