The representation of a medicinal product marketed product marketed by a single organisation (supplier) in a single jurisdiction under a single name (which may be a trade or brand name) and which contains the same set of active ingredient substances, regardless of any modification of those active ingredient substances. It is a subtype of, and real world equivalent to, the Medicinal Product Only (MP only) class in the international core.
Use Cases
The following use cases are supported by the Real Medicinal Product concept class:
- Describing medication statements for a medication profile when the detail of the exact product used is not known; e.g., "patient states they used Ventolin for 5 years in childhood"
- Decision support and protocol/guideline management may have a use case for this class (for example, to change presentation or strength within a product family)
- Pharmacovigilance (abstract representation of a manufactured medicinal product)
Discussion
...
The real medicinal product class is a grouper concept for products containing the same set of active ingredient substance(s) and marketed under the same name by the same supplier.
Single ingredient substance branded products
...
The RMP "Lipitor Zocor (product)" shown in a taxonomic view in Figure 2 below presents products marketed by Pfizer Organon Pharma UK Limited under a single name (LipitorZocor) and containing only atorvastatin simvastatin as the base active ingredient substance and shows the RCD concepts associated with it:

For those products without a unique (i.e., invented) product name, where the product uses the international non-proprietary name of the active substance as its product name (i.e., so called " generic products"), extensions may choose not to populate the Real Medicinal Product classProduct class, as shown below, with each RCD being associated directly with the CD in the International content:
Figure 3: Example of authorised real clinical drug "generic" products where a real medicinal product concept has not be authored
Alternatively, for "products without a unique (i.e. invented) product name (generic products" ) a national extension may choose to populate the Real Medicinal Product using the generic name AND supplier, since with the manufacturer/supplier organisation, this gives a unique RMP concept, as shown below:
Figure 4: Example of authorised real clinical drug "generic" products where a real medicinal product concept has been authored using product and manufacturer name
Note that here the product name attribute is valued as "simvastatin", which in text looks similar to both the substance concept 387584000 | Simvastatin (substance) | and to the two medicinal product concepts 96304005 | Product containing simvastatin (medicinal product) | and 777537002 | Product containing only simvastatin (medicinal product) |. But it is a different concept and has its own semantic tag of "product name"; it is therefore a different concept (unit of thought): Simvastatin (product name).777537002 | Product containing only simvastatin (medicinal product) |
Multi-Ingredient substance branded products
One of the definitional attributes for fundamentals of a Real Medicinal Product is that it represents a single set of active ingredient substances, reflecting its associated MP only class that also represents a single set of active ingredient substances, without dose form or strength information.
The RMP "Inegy (product)" shown in a taxonomic view in Figure 2 below presents products marketed by Organon Pharma UK Limited under a single name (Inegy) and containing only simvastatin AND ezetimibe as the active ingredient substances, and showing the RCD concepts associated with it:
Figure 5: Diagram showing a branded multi-ingredient substance real medicinal product and its supporting real clinical drug concepts (note, not all possible real clinical drug concepts are shown)
Not all authorised . Therefore not all medicinal products that share the same (invented) product name will relate to a Real Medicinal Product, especially for over the counter (OTC) medicines, where a commercial "brand family" may contain products with different active ingredient sets which would therefore have different MP only representations. For example: , some cough and cold product ranges span expectorant products, cough suppressants, antipyretics and decongestant products, with different sets of active ingredients in each , but all sharing the same brand name.
In the example below, the three real clinical drug products all share the same product name ("Benylin®") in one jurisdiction, but they do not relate to a single real medicinal product because they each relate to different Medicinal Products due to differences in their active ingredient substances.

A national extension may choose to populate RMPs for "brand families" that contain products with different active ingredient sets by extending the product name concept to include enough detail to scope just a single active ingredient set, as shown below:

Existing national terminology equivalents for real medicinal product:
- Trade family in NHS dm+d
- Trade Product (TP) in AMT/NZULM (possibly – AMT appears to allow strength and dose form modifiers)NZULM
- Brand Name (BN) in RxNorm (possibly)
Attributes

The following attributes apply to Real Medicinal Product (RMP)
...
The Real Medicinal Product concept class has two concepts in a national extension. The RMP class has two attributes inherited from the Medicinal Product (only) class in the international core content and two additional attributes.
