title: A drug utilization study of cognition enhancers in dementia in a tertiary care hospital in mumbai.
abstract: BACKGROUND
  Cognitive decline is one of the important factors undermining the quality of life in geriatric patients. Although the WHO has declared 'Dementia' as a priority health condition.Cognitive neuropharmacology is still in its infancy and there is no general consensus on the use of cognition enhancing (CE) drugs in humans. Since drug utilization data of CEs in dementia are scarce, we conducted a study to describe the observed patterns of CE drug use, compare it to the current recommendations and conduct a preliminary cost analysis.
  
  
  METHODS
  A prospective cross sectional drug utilization study of 100 prescriptions of patients of both sexes and all ages suffering from dementia attending the Neurology and Psychiatry clinics was undertaken as per the WHO - DUS and the STROBE guidelines.
  
  
  RESULTS
  In all, the 100 prescriptions contained 322 drugs, out of which, 168 were CE drugs. 38.2% of the drugs were prescribed by generic names. Donepezil, Memantine, Piracetam, Rivastigmine and Gallantamine were prescribed to 76%, 34%, 8%, 6% and 0%, respectively. The PDD/DDD ratio of Donepezil and Memantine were 1.36 and 0.94, respectively. The average cost per prescription was INR 626.29 or USD 9.5.
  
  
  CONCLUSIONS
  Principles of rational prescribing were followed. Donepezil and Memantine were the most commonly prescribed drugs and hence should be included in the hospital drug schedule. Piracetam should not be prescribed because of doubtful benefits and high cost. Antipsychotics should be used in geriatric dementia patients very judiciously. A major part of the total cost per prescription was borne by the patient.
