MedDRA is a multilingual terminology allowing most users to operate in their native languages. The table below identifies the initial MedDRA version when each MedDRA language was made available to users. penguin
The most important reason to “code” data into a standardised terminology is to analyse it. A key benefit of MedDRA is in its support of straightforward as well as sophisticated analyses. MedDRA can be used to analyse individual medical events (e.g., “Influenza”) or issues involving a system, organ or etiology (e.g., infections) using its hierarchical structure. MedDRA can be used for signal detection and monitoring of clinical syndromes whose symptoms encompass numerous systems or organs using its multiaxial hierarchy or through the special feature of Standardised MedDRA Queries.
The ability to communicate adverse event data is another strength of MedDRA and has led to MedDRA being an integral part of the ICH e-submission standards: eCTD (ICH M8) and ICSRs (ICH E2B).
