title: [Pharmacoepidemiological study of the use of psychotropics in hospitalized patients].
abstract: OBJECTIVE
  To assess consumption and the exposition of patients admitted to the Universitary Hospital of the Interamerican Open University (UAI), between October and December of 2007-2009.
  
  
  METHODS
  Descriptive observational study. The information was obtained of the Pharmacia Sector. We analyze the dispensations (Units); the exposition was evaluated using the defined daily dose per 100 beds/day. We analyzed how many of the psychotropics used were considerated essentials drugs for the WHO. We assessed the adverse drug reactions registered.
  
  
  RESULTS
  The psychopharmacological drugs represented the 43%, 41%, and the 44% (period 2007-2009) of the drugs used for the Central Nervous System. The benzodiazepines represented more of the 50% of the psychopharmacological drugs used. The exposure was respectively of 57%, 66%, and 40% (for all the patients admitted to the hospital on period 2007-2009). The essential medicines used fluctuate between 41% and 48%. From 32 adverse reactions connected with the Central Nervous System, 20 (62.5%) were attributed to psychotropics.
  
  
  CONCLUSIONS
  1. We established the quantity of the psychotropics dispensations, as well as the level of the exposure. 2. The psychotropic utilization of the essentials medicines list of the WHO was above 40%.
