Drug utilization study of psychotropic drugs in outdoor patients in a teaching hospital

Abstract

Background: Psychotropic drugs have had a remarkable impact in psychiatric practice. However, their utilization in actual clinical practice, effectiveness and safety in real life situation need continuous study. Materials and Methods: A prospective cross sectional study was carried out for 6 months. Patients of all ages and both sexes were included in the study while in-patients, referred patients and patients of epilepsy were excluded. Using World Health Organization basic drug indicators, the prescribing pattern was analyzed. Results: The numbers of psychotropic drugs prescribed per patient were 2.96. Anti-anxiety drugs (82.83%) were most frequently prescribed psychotropic drugs in various psychiatric disorders. Usage of antipsychotic drugs was in 70.15% cases. Atypical antipsychotic drugs (43.83%) were prescribed more frequently than the typical antipsychotic drugs (26.32%). Prescribing frequency of selective serotonin reuptake inhibitors (36.66%) was more than the tricyclic antidepressant (21.96%) and atypical antidepressant drugs (1.83%) in major depression. Use of mood stabilizers was restricted only to bipolar mood disorders. Central anticholinergic drug was co-prescribed in as many as 88.15% patients receiving antipsychotic drugs. Conclusion: Anti-anxiety drug (Benzodiazepine (BZD)) usage was extensive in various psychiatry disorders. Rational use of BZD requires consideration/attention to dose and duration of usage as well as drug interactions with other psychotropic drugs. Routine use of central anticholinergic drug along with atypical antipsychotic drugs also, could not be justified.
