Guidelines for the usage of psychoactive drugs for behavioral and psychological symptoms of dementia (BPSD) were issued by the Japanese Ministry of Health, Labour and Welfare in July 2013. Using the Anatomical Therapeutic Chemical (ATC) classification with prescription data, we surveyed the usage of psychotropic drugs in patients with dementia. N05C (hypnotics and sedatives) was the most frequently prescribed class of drugs [9,920 (19.7%) individuals]. In addition, there are few prescription ratios of risperidone in comparison with 5.6% and the survey in the UK. Although anti-anxiety drugs should not be used as per BPSD guidelines, etizolam was prescribed in a considerable proportion of patients (6.2%). In addition, with respect to prescription of combinations of antipsychotics in the same month, the highest rate was found for risperidone and tiapride [209 (2.4%) individuals]. In addition, 39 individuals were prescribed antipsychotics that are contraindicated for patients with diabetes. When the number of the clinical departments is as above 2, the ratios to become the contraindicated prescription, careful administration prescription of the antipsychotic increase with significant difference (p<0.01). The increased of the number of the clinical departments tended to increase the ratio of the contraindications and careful administration prescription. Thus, the need for a family doctor to prevent such situations was suggested, which was introduced by the 2014 Medical Treatment Fee Revisions.
