OBJECTIVES: An aging population translates into an increase in drug use, while medication management is challenged by the uniqueness of geriatric pharmacology. Our objective is to understand the most frequent IMUs dispensed from community pharmacies. METHODS: We used Beers’ 2002 Criteria (regardless of diagnoses and conditions) in our analysis.  The prescription repository from a downtown community pharmacy (Yalova, Turkey) with a diverse socio-economic demographic profile was retrospectively monitored to identify IMU.  The Social Security Institution (SGK)’s “Medula” database was utilized to identify patients to whom at least one prescription was dispensed in the month of October 2011. The patient records were tracked back to the period between September and November 2011 to analyze their prescriptions details.  SGK-Medula prescriptions for 192 elderly patients (≥60 years-old) were identified (108 female and 84 male). RESULTS: From data analysis, 424 cases of IMU were identified. Each patient was exposed on average to 2.2 IMUs. The majority (61.8%) of all IMU cases involved non steroidal anti-inflammatory drugs (NSAID).  The average use of NSAID per patient was 1.36.  There was no statistically significant difference between female and male NSAID IMU. The second most IMU was chlorpheniramine usage, with 9% of all IMU cases; again no statistically significant difference was found between females and males.  The third most frequently observed IMU involved nitrofurantoin in males (13.1%), and hydroxyzine in females (10.2%). Regardless of gender, ferrous sulphate (4.0%) was ranked the third overall most recorded IMU. Stimulant laxatives, alprazolam, doxazosin, and ticlopidine were also among the frequently observed IMU cases in this study. CONCLUSIONS: Prescriptions for the elderly should be systematically evaluated to check for IMU. NSAIDs, chlorpheniramine, nitrofurantoin, hydroxyzine, and ferrous sulphate may be especially worrisome due to high prevalence of exposure to these agents.
