Medicines and Healthcare products Regulatory Agency

The Medicines and Healthcare products Regulatory Agency (MHRA) is the government agency which is responsible for ensuring that medicines and medical devices work, and are acceptably safe.


 Changes in the names of medicines - March 2016

Finding reliable information about medicines can be a problem, especially on the Internet. has been developed to provide information that you can trust.

We currently provide three sources of information:

1. electronic Medicines Compendium (eMC)

The eMC provides electronic Data Sheets, Summaries of Product Characteristics (SPCs) and Patient Information Leaflets (PILs).

It provides information on thousands of licensed medicines available in the UK.

The eMC is continuously updated with new and revised SPC and PIL information, which, after approval by the licensing authorities, is submitted directly by pharmaceutical companies.

2. Medicine Guides>

Medicine Guides are a new source of information for members of the public who are looking for information about individual medicines that is up-to-date, reliable and understandable. The Medicine Guides are being developed as part of the Medicines Information Project which aims to provide people with information about medicines, conditions and the different treatment options available. The project is being developed in partnership with NHS Direct and with the support of a wide range of organisations.

3. Dictionary of Medicines and Devices Browser

The Dictionary of Medicines and Devices (dm+d) is part of the UK Clinical Products Reference Source (UKCPRS) project being undertaken by the NHS Information Authority and implemented by the Prescription Pricing Authority (PPA).

The dm+d will provide a unique product identifier for every prescribable item in primary care (eventually UKCPRS will include the Secondary Care Drug Dictionary & Medical Devices Dictionary).

This use of unique codes will facilitate more efficient processing and reimbursement of prescription, electronic Prescribing and the electronic Patient Record. The coding also provides substantial opportunities in audit capability.

The dm+d is a subset of SNOMED CT (Systemised Nomenclature of Medicine) and thus is recognised as an NHS standard.

Medicines Compendium Updates

With around 20,000 changes every year to the regulated medicines information in the UK, it is important to ensure awareness of these changes and to provide access to the very latest versions of the SPCs and PILs.

The Medicines Compendium Updates page enables recipients of the Medicines Compendium 2005 and users of the electronic Medicines Compendium (eMC) to view changes to SPCs over time, including changes that have occurred since the Medicines Compendium was published.


eMIMS is one of several titles published by Haymarket Medical Limited. eMIMS' core content mirrors that of its sister publication MIMS, which was launched in 1959 and remains a leading source of up-to-date prescribing information used by almost 70 per cent of general practitioners (GPs) in the UK.

In addition to the drug records and quick reference tables featured in MIMS, eMIMS contains a wealth of supplementary information, including summaries of key clinical guidelines, patient fact sheets on a range of diseases and conditions, a directory of self help groups for patients, and an interactive cardiac risk calculator.
