title: Utilization of potentially inappropriate medications in elderly patients in a tertiary care teaching hospital in India.
abstract: OBJECTIVE
  To evaluate the use of potentially inappropriate medicines in elderly inpatients in a tertiary care teaching hospital.
  
  
  METHODS
  Retrospective analysis was performed for cases of elderly patients admitted between January 2010 and December 2010. Data on age, gender, diagnosis, duration of hospital stay, treatment, and outcome were collected. Prescriptions were assessed for the use of potentially inappropriate medications in geriatric patients by using American Geriatric Society Beer's criteria (2012) and PRISCUS list (2010).
  
  
  RESULTS
  A total of 676 geriatric patients (52.12% females) were admitted in the medicine ward. The average age of geriatric patients was 72.69 years. According to Beer's criteria, at least one inappropriate medicine was prescribed in 590 (87.3%) patients. Metoclopramide (54.3%), alprazolam (9%), diazepam (8%), digoxin > 0.125 mg/day (5%), and diclofenac (3.7%) were the commonly used inappropriate medications. Use of nonsteroidal anti-inflammatory drugs (NSAIDs) in heart and renal failure patients was the commonly identified drug-disease interaction. According to PRISCUS list, at least one inappropriate medication was prescribed in 210 (31.06%) patients.
  
  
  CONCLUSIONS
  Use of inappropriate medicines is highly prevalent in elderly patients.
