Over recent years, use of self-medication by patients to help prevent and treat their own medical conditions has become increasingly widespread. However, despite provision of warnings and the taking of precautions, health hazards due to medication have occurred and continue to occur. In order to ward off such incidents, it is necessary for both children and adults to be educated about appropriate drug use. And, it is desirable that pharmacy students participate in this medicinal education as a means of affirming what they have learned and improving their communication skills at an early stage in their professional development. In 2008, we held medicinal education classes for pupils and parents at three elementary schools in Aichi Prefecture with the aim of promoting appropriate drug use. Each class comprised of two parts: an introductory lecture in quiz form, lasting about 30 minutes, and a 30-minute participatory group experiment. Subsequently, the activities carried out in both parts were evaluated across 6 items and 3 items respectively, and scored from Satisfied to Unsatisfied (4-step scale) by the pupils and their parents. We also conducted a questionnaire survey on this activity to the pharmacy students. We achieved successful results, gaining high Satisfied levels (better than 90%) in all items. This activity benefited both the children and the pharmacy students. It not only provided education for the general public regarding the appropriate drug use, but is also helping to foster the development in Japan of well-trained future pharmacists.
