spontaneous reports cover only a small proportion of the existing adverse drug reactions …

Introduction Efficient searching and coding in databases that use terminological resources
requires that they support efficient data retrieval. The Medical Dictionary for Regulatory …

Computerised queries in spontaneous reporting systems for pharmacovigilance require
reliable and reproducible coding of adverse drug reactions (ADRs). The aim of the Medical …

In the context of PROTECT European project, we have developed an ontology of adverse
