# Introduction

## Background

EDQM (the European Directorate for Quality of Medicines - a directorate of the Council of Europe) is a leading organisation that protects public health by enabling the development, supporting the implementation and monitoring the application of quality standards for safe medicines and their safe use. These quality standards are recognised as a scientific benchmark and applied worldwide.

One of these quality standards is the "Standard Terms", a set of concepts used in the definition and description of medicinal products; these include the Pharmaceutical dose form (i.e. the dosage form), Route or method of administration, and certain important Packaging items such as the Container, Closure and Administration device. These Terms were initially produced by the European Pharmacopoeia (Ph. Eur.) Commission following a request from the EU Commission prior to being overseen by EDQM. Now, Standard Terms are managed by EDQM in compliance with the ISO 11239 standard for the description of pharmaceutical dose forms, which is itself part of the IDMP (**ID** entification of **M** edicinal **P** roducts) suite of standards, and as such, gives them global applicability as opposed previously a European focus. Regulatory agencies beyond Europe may submit requests to EDQM for new Terms; supporting evidence for all requests for new Terms must be provided.

The Terms are designed to be used in marketing authorisation applications, medicinal product labelling (including the summary of product characteristics (SmPC), and in electronic communications about medicines. Additionally, in the last 5 years, the Standard Terms have been used for related purposes such as adverse event reporting (pharmacovigilance) and clinical trials. But, whilst the primary use is in the regulatory domain, the Standard Terms bring information to the patient/user/prescriber through their use in SmPC, and it is this that underpins the requirement to map the EDQM Pharmaceutical Dose Forms to the Pharmaceutical Dose forms in SNOMED CT, where dose form is one of the definitional attributes of the Clinical Drug and Real Clinical Drug concepts.

## Document Purpose

The purpose of this document is to describe the principles and guidelines that have been used when producing the EDQM to SNOMED CT pharmaceutical dose form map so as to provide support and information for the users of the map such that the map can be used to its best effect.

## Document Scope

This user guide covers the following topics:

* The **Use Cases** for the map
* The **Policies** that govern the map in its entirety
* The **Principles** that guide the specific decisions on individual maps
* The **Implementation Guidance** that should be followed when using the map in one or more of its use cases so as to obtain best value from it

## Audience

The EDQM to SNOMED CT dose form map and user guide are provided by SNOMED International, in collaboration with EDQM, to support the mapping use cases of SNOMED International Members and Affiliates that:

* Are using EDQM dose forms in the description of medicinal products in their regulatory, national, local or system medicinal product dictionary; and
* Need to use SNOMED CT dose forms to support one or more use cases, e.g. authoring a national SNOMED CT drug extension, international interoperability, or clinical decision support.

For a more complete list of use cases, please refer to Section 2 Use Cases.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.snomed.org/implementation-guides/edqm-to-snomed-ct-dose-form-map-guide/1-introduction.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
