INTRODUCTION
Schizophrenia is a chronic and debilitating psychiatric
illness consisting primarily of symptoms such as
hallucinations and delusions, also termed as “positive”
symptoms. In addition, individuals may experience
“negative” symptoms which include loss of sense of
pleasure, social withdrawal, impoverishment of thoughts
and speech and flattening of affect. According to WHO
estimates, schizophrenia affects approximately 24 million
people worldwide.

The prevalence of schizophrenia
varies across the world, within countries, and at the local
and neighborhood level.

The most recent publications estimate that prevalence of
schizophrenia ranges from 1.4 to 4.6 / 1000 and the
median incidence varies from 0.15 to 0.20 / 1000

ABSTRACT
Background: Schizophrenia is a chronic and debilitating psychiatric illness affecting around 0.3-0.7% of people at
some point in their life. The rate of schizophrenia and related disorders is affected by some environmental factors and
social variables. Therefore, pharmacoepidemiological survey of patients suffering from schizophrenia was carried out
to analyze the sociodemographic profile and drug prescribing pattern.
Methods: A prospective observational study was conducted in psychiatry OPD of a tertiary care hospital for nine
months. Diagnosis of schizophrenia was made according to DSM IV-TR criteria. Prescriptions were analyzed for
socio demographic details, distribution of subsets of disease and psychotropic drugs prescribed.
Results: Amongst 196 cases analyzed, 55.61% were males, 69.9% were below 40 years, 52.04% unmarried, 61.22%
belonged to low income group, 82.14% unemployed and 58.16% came from urban locality. Paranoid schizophrenia
(79.59%) was the most common diagnosis and a total of 402 psychotropic drugs were prescribed. Average number of
psychotropic drugs per prescription was 2.05. Atypical antipsychotics (80.09%) were prescribed more commonly than
typical antipsychotics; olanzapine (42.48%) was the commonest antipsychotic drug followed by risperidone
(21.68%), haloperidol (19.91%), quetiapine (7.96%), aripiprazole (4.42%) and clozapine (3.54%). As an adjunctive
treatment escitalopram, clonazepam and carbamazepine were the commonly prescribed antidepressant, anxiolytic and
antimanic agent respectively.
Conclusion: Low socioeconomic status, unemployment, urban locality and living alone are the sociodemographic
factors associated with schizophrenia. The treatment pattern observed correlates with the changing trends in the
treatment of schizophrenia world over.
