Examples: bulk parenteral solutions, insulins, patches

The unit of presentation usually either uses the same word (even though it is a different concept) as the (package item) container, or the (package item) container is a more granular concept and the unit of presentation uses a less granular term. However, although presentation strength is expressed as "per one unit of presentation", the clinically relevant strength is the concentration strength, as almost all are used in individually calculated and variable amounts. Note that the unit of presentation is likely to be useful in description of the medicinal product concept at some level; insulin presented in a multi-dose vial will be used/administered differently from insulin presented in a cartridge for use within a "pen device".

Example: A pack of 5 cartridges each containing 1.5mL soluble human insulin 100 units/mL solution for injection

Examples: various tablets, capsules, cachets, pessaries, suppositories, tampons

The unit of presentation is usually a less granular term than the manufactured dose form, and often corresponds to the basic dose form. Strength is expressed as "per one unit of presentation" and the presentation strength and the concentration are exactly the same.

Example: Bottle of 56 simvastatin 40mg oral tablets

To correctly interpret "one countable instance of a whole of medicinal product ", it is important that this is seen in the context of the overall description of a medicinal product, which is always presented from the manufacturer as a "packaged medicinal product". Note that description of packaged medicinal products is outside the scope of the international release but may be included within a national extension. The IDMP Medicinal Product model describes this, showing how the Manufactured Item is related to the Packaged Medicinal Product via the Package Item (Container). This is a recursive class that represents both the package as supplied by the manufacturer (and, for example, labelled with the GTIN, the batch number and the expiry), and through a recursive relationship, with any sub-packages inside the outer pack.

By describing the various standard patterns of products with their basic dose forms and intimate containers, consistent representation of strength based on unit of presentation can be maintained.

Examples: oral solutions, suspensions, emulsions, syrups

This is a variation on the metered dose presentation; the unit of presentation supplied by the manufacturer to provide the “metered dose” is the 5mL spoonful, since this represents “the quantity of product that is administered by filling a single spoon administration device” [EDQM]. Strength is expressed as “per one unit of presentation” (per 5 mL [spoonful]) BUT the presentation strength and the concentration are NOT the same, since these are continuous liquids, so the concentration strength of “per 1 mL” will usually be a different value. Note that explicit representation of the medicine spoon would be as an administration device, and is therefore out of scope of the international Medicinal Product hierarchy. National extensions may wish to represent the inclusion of a medicine spoon (or indeed any other administration device such as an applicator) in the package description (as in IDMP, for example) should the use case(s) require.

Example: A bottle of 125 mL of aciclovir oral suspension 200mg/5mL

Examples: bulk powders and granules, bulk liquids, semi-solids

These presentations are not particularly bound by their container in any way that is meaningful in terms of their use or administration; the Manufactured Item is a continuous presentation and almost all are used in individually calculated and variable amounts.

For example,

• Hydrocortisone cream for cutaneous use is contained in a tube, but its use is based on how much is squeezed out and applied to the skin.

• Chloramphenicol eye drops are presented in a dropper bottle, but they are administered drop by drop and although the dropper bottle aims to deliver a roughly uniform sized drop to the eye, they are not "metered dose containers" in the way that containers with valves are.

A unit of presentation is not usually given for these products. The pack size (not relevant for SNOMED international model) is given as the Manufactured Item quantity. Strength is expressed as a concentration and as such the presentation strength and the concentration are exactly the same.

Examples: vials, ampoules, sachets, containing solid dose forms such as powders or granules which may or may not be dissolved before administration

The unit of presentation usually either uses the same word (even though it is a different concept) as the (package item) container, or the (package item) container is a more granular concept and the unit of presentation uses a less granular term. Strength is expressed as "per one unit of presentation" and the presentation strength and the concentration are exactly the same.

Examples: parenteral solutions, unit dose nebuliser solutions

The unit of presentation usually either uses the same word (even though it is a different concept) as the (package item) container, or the (package item) container is a more granular concept and the unit of presentation uses a less granular term. Presentation strength is expressed as "per the amount of liquid bounded by the unit of presentation" but concentration strength is per mL (and therefore is often different).

Example: A pack of 10 ampoules each containing 20mL of metoclopramide hydrochloride for solution for injection

Examples: various inhalers, nasal sprays, some cutaneous sprays/foams

The unit of presentation is the actuation, the “single operation of a metered-dose pump, valve or other equivalent dosing mechanism” [EDQM].

Strength is expressed as “per one unit of presentation” and the presentation strength and the concentration are exactly the same.

Example: Single inhaler containing a total of 200 actuations worth of salbutamol, 100 micrograms per actuation, packaged in a box
