Abstract
It is possible that traffic accidents caused by medication use are among the most underestimated compared with other types of accidents.This issue stems from human factors that affect driving even before it begins, increasing the likelihood of accidents. Therefore, it is a predictable and avoidable factor.In this context, it is essential to gain a deeper understanding of the medications that pose the greatest risks and how they influence driving.To do this, we will study the groups of drugs marketed in the European Union that can affect driving, analyzing the DRUID classification of medicines to determine which group of drugs can have the most influence on driving.To this end, the DRUID classification has been reviewed, the technical data sheets of medications marketed in Spain have been analyzed, focusing on the sections regarding "Effects on driving" and "Adverse effects," and the frequency of these effects has been evaluated to identify the medications with the greatest impact.
