Introduction: This study aimed to determine the trends in the use of medicines that can affect the recognition function of patients aged ≧70 years. Since 2015 when the “Safe Drug Treatment Guidelines for the Elderly” was revised, these medicines are dispensed at a community pharmacy located in a satellite city. Methods: We compared the dispensing results from 2014 to 2015-2019 and investigated the ratio of prescriptions containing the medicines that can affect the recognition function using the clinical department and medicine type. Results: Prescriptions containing medicines that can affect recognition function have been on a downward trend since 2015. During this period, the number of medicines per prescription did not decrease, and the medicines that can affect recognition function were replaced with other medicines. On the other hand, no decrease in the number of medicines that can affect recognition function was observed in internal medicine. In medicine type, the ratio of benzodiazepines drugs decreased; however, it increased again in 2019. Conclusion: There was a decreasing trend in the use of medicines that can affect recognition function of the elderly in departments other than internal medicine after 2015.
