Development and validation of a driving simulator for evaluating the residual effects of drugs on driving performance - sensitivity analysis using zopiclone as a positive control: Study Protocol Clinical Trial (SPIRIT Compliant).

Introduction: Drugs acting on the central nervous system (CNS), especially hypnotics, can impair driving. The US Food and Drug Administration started requiring pharmaceutical companies to evaluate the residual influence of CNS agents on driving performance to review their recommended doses. Although it is important for physicians to discuss automobile driving while on medication with patients to promote traffic safety, the package inserts of most CNS agents in Japan uniformly prohibit patients from driving.

Protocol for the development and validation of a driving simulator for evaluating the influence of drugs on driving performance.

Introduction: Although automobile driving is often necessary in daily life, most package inserts for psychotropic drugs in Japan prohibit patients from driving under the influence of medication. This may be partially because no system to evaluate the influence of drugs on driving performance has been established. Standardized evaluation methods have been established in the Netherlands and the United States, but these cannot be implemented in Japan because of differences in road situations, traffic laws, and ethnicities.
