TL;DRIDMP stands for Identification of Medicinal Products, a set of five ISO standards that together give a medicine a single, unambiguous description that regulators and computer systems can exchange across borders. The goal is that one medicine is identified the same way in every country, no matter the trade name or the national code.
The problem IDMP solves is fragmentation. The same active substance reaches the market under different brand names, in different pack sizes and with different national identifiers, and each regulator historically described it in its own structure. IDMP defines a common data model, so that a medicinal product, its pharmaceutical form, its substances, its dose forms and its units all carry standardised, machine-readable identifiers. That is what lets a system in one country recognise that a product in another country is, pharmaceutically, the same thing.
IDMP is not a single document. It is a family of five ISO standards, each covering one layer of the description. Together they specify the data elements and structures for the unique identification and exchange of regulated information on medicines.
| Standard | Scope | Role in IDMP |
|---|---|---|
| ISO 11615 | Regulated medicinal product information | The medicinal product as authorised, the level that carries the MPID |
| ISO 11616 | Regulated pharmaceutical product information | The pharmaceutical product, active ingredient, strength and form, the level that carries the PhPID |
| ISO 11238 | Substances | Active and other substances, with unique substance identifiers |
| ISO 11239 | Pharmaceutical dose forms, units of presentation, routes of administration and packaging | Controlled terms for how a medicine is presented and given |
| ISO 11240 | Units of measurement | Standardised units, so strengths and quantities are exchanged unambiguously |
The layers stack. A substance under ISO 11238 is combined with a strength, a dose form from ISO 11239 and a unit from ISO 11240 to define a pharmaceutical product under ISO 11616, and one or more pharmaceutical products, together with a name, packaging and a marketing authorisation, make up the medicinal product under ISO 11615. Read from the bottom up, the five standards turn a loose description into an exact, reproducible identity.
In the European Union, IDMP is being implemented through the European Medicines Agency and its SPOR master data services. SPOR stands for Substances, Products, Organisations and Referentials, delivered as four services: SMS for substances, PMS for products, OMS for organisations, and RMS for the controlled vocabularies that the other three draw on. On top of this master data sit the IDMP identifiers. In the EU implementation the product data itself is exchanged as structured records, so systems consume it directly rather than reading it off a document.
| Identifier | Level | What it identifies |
|---|---|---|
| MPID | Medicinal product | The authorised product in one country, under ISO 11615 |
| PCID | Packaged product | A specific pack of that product |
| PhPID | Pharmaceutical product | The active ingredient, strength and form, identical across countries, under ISO 11616 |
The PhPID is the one to remember. Because it identifies a pharmaceutical product by its active ingredient, strength and form rather than by a brand or a national code, the same PhPID appears for the same combination in every country. That makes it the matching key for cross-border work, for example finding which product in another member state corresponds to a given German one. The regulatory licence itself is recorded separately as the EU marketing authorisation number, in the authorisation layer of the same structure.
This is where precision matters, because the rollout has been iterative rather than a single switch. Electronic submission of data on authorised human medicines to the EMA has been mandatory since July 2012, and that data is being migrated to the ISO IDMP compatible format through the phased SPOR programme.
For anyone who works with medicine data, IDMP is not an abstraction. Every marketing authorisation holder has to describe its products in the IDMP structure, which creates ongoing obligations and a steady stream of data work, and each iteration of the SPOR programme adds fields that have to be sourced, reconciled and kept current. That is the commercial reality behind IDMP: the standard turns product identification into continuous data maintenance, and that maintenance is what drives demand for tooling and for reliable master data. For parallel importers, wholesalers and software vendors the same standard is an opportunity: once products carry stable EU identifiers, matching a product across markets becomes a data question rather than a manual one.
pharmazie.com carries a dedicated IDMP tool suite alongside IDMP-structured EU data. The tools resolve terms and codes, and the EU medicines database presents each product with its IDMP product details.
One honest limitation: the EMA IDMP data contains no PZN. Because the EU identifiers and the German national trade code live in separate systems, bridging an MPID or PhPID to the matching PZN is the genuinely hard part, and it depends on a data source that holds both keys side by side. A broader conversational agent that queries the SPOR and PMS FHIR services directly exists at pharmazie.com only as a prototype, not as a live product feature.
