An abstract representation of a medicinal product described by its active ingredient substances and a grouping dose form concept (based on the intended site of administration for the dose form group) but without reference to its any product strength. The

and are described in detail in the Editorial Guidance section Grouper Based on Intended Site. These These grouper concepts gather together all the formulations (solid, semi-solid, liquid or gaseous manufactured dose forms) that have the same intended site of administration. The intended site of administration of a dose form concept is a description of the general body site (i.e. not exactly anatomically explicit - no laterality etc.) where the dose form will be administered, For example, products formulated with a dose form of eye drops are required to meet various pharmacopoeial standards of sterility, particulate contamination and pH as they are intended to be administered to an "ocular" site. For further information see section 5.3.2.7 of ISO 11239:2012 Health informatics - Identification of medicinal products — Data elements and structures for the unique identification and exchange of regulated information on pharmaceutical dose forms, units of presentation, routes of administration and packaging.

An abstract representation of a medicinal product based on description of active ingredients ingredient substances it contains , but not limited by that description, and on the (generalised) intended site of use for the product.
For example, "Product containing amoxicillin in oral dosage form" represents the group of products that must contain some amoxicillin (be it amoxicillin sodium or amoxicillin trihydrate or amoxicillin base), but may also contain other active ingredients, such as clavulanic acid, in manufactured dose forms such as oral suspension, oral capsule (any type), oral tablet (any type).

Use case(s) supported by MPF (containing)
The main use case for the MPF (containing) is for analysis; as an aggregation concept for use in research. It may be that this concept may be used to support the modelling of other concepts in the future.

An abstract representation of a medicinal product based on description of only and exclusively the active ingredient(s) it contains and on the (generalised) intended site of use for the product.
For example, "Product containing only amoxicillin in oral dosage dose form (medicinal product form)" represents represents products that must contain only amoxicillin (be it amoxicillin sodium or amoxicillin trihydrate), with no other active ingredients in manufactured dose forms such as oral suspension, oral capsule (any type), oral tablet (any type).

For concepts that have two or more active ingredient substances that are modifications of the same base active ingredient substance (i.e. parent ingredient substance) and where one is a further modification of the other (for example, a multi-ingredient product containing both dexamethasone phosphate and dexamethasone sodium phosphate, where the dexamethasone phosphate is a modification of dexamethasone (base) and dexamethasone sodium phosphate is a further modification of the dexamethasone phosphate) and where MP precisely concepts are required, and for single ingredient product concepts where the active substance is an ingredient in these multiple modification multi-ingredient products, the following extra ingredient count attribute will be required n order to support correct relationships generated by the MRCM:

As described in the MRCM rules, for practical and pragmatic reasons the additional ingredient count attributes have to be applied iteratively based on requirement.
Use cases supported by MPF (only)
...
- Internationally and nationally in decision support (especially drug interaction checking) and in protocols and treatment guidelines
- Internationally and nationally for interoperability of patient medication information such as in patient summaries and medication profiles, where patient information may only be available in using an abstract description (e.g. "patient reports they were taking oral captopril for 5 years")
- Internationally for the provision of cross border care, where a particular formulation of a medicinal product from one jurisdiction may not be present in a second jurisdiction; the MPD (only) class can support finding alternatives
- In pharmacovigilance, especially for description of concomitant medications where less information may be available (see also below in IDMP Compatibility)
- In analysis and research
- As a supporting attribute for other concepts elsewhere in SNOMED CT

IDMP Compatibility
A concept at this level, despite using the universal restriction, does not directly correspond to any concept currently in the IDMP suite of standards.
The Level 3 Pharmaceutical Product concept (PhPID_SUB_C3) uses a granular administrable dose form concept for a product which will have an intended site of administration (bearing in mind that the exact implementation of ISO 11616 is not yet known). The MPF uses a more abstract dose form grouping concept where the grouping is on the basis of the intended site of administration for manufactured dose form (with some exceptions for oral antibiotic products that are supplied as powders/granules but dispensed to patients as solutions/suspensions). However, there should be little difference in the intended site of administration between a manufactured dose form and its administrable form for those dose forms that do not require transformation. For some groups of products, the MPF (only) concept has the potential to bring additional value to users beyond PhPID_SUB_C3 because it is a larger grouping concept. For example:
For example, the dose form intended site concept
| Scg expression |
|---|
385276004 | Ocular dose form (dose form) | |
concept 385276004 | Ocular dose form (dose form) | covers 14 more granular pharmaceutical dose forms, of which two would undergo transformation to different administrable dose forms, but still with the ocular intended site. This means that the single MPF grouping concept will be relevant to a considerably larger group of actual products than the 12 potential PhPID_SUB_C3 concepts for the same active ingredient substance(s) that might exist in IDMP.
...
This concept class, which is not shown in any of the overall diagrams in the introductory section, would be a representation of a medicinal product based on description of only and exclusively the precise active ingredient(s) it contains and on the (generalised) intended site of use for the product. For example, "Product containing precisely amoxicillin trihydrate in oral dosage form" represents products that must contain only amoxicillin trihydrate (not amoxicillin sodium or amoxicillin base) as the precise ingredient substance, with no other active ingredients in manufactured dose forms such as oral suspension, oral capsule (any type), oral tablet (any type). This class is not part of the international releaseedition, but may be of use in national extensions. It would be modelled in the same way as the MPF only, but would use the precise active ingredient attribute and the two additional ingredient count attributes if and when required, using the same rules as for MP precisely.
