Abstract

Objectives Previous literature on the prescription change among patients with schizophrenia mainly focused on antipsychotics. This study investigated chronological change in the patterns of discharge medication among inpatients with schizophrenia at a psychiatric inpatient unit of a university-affiliated hospital. Methods All admission records at a psychiatric unit of Hanyang University Guri Hospital with discharge diagnosis of schizophrenia during two different five-year time frames (1996-2000 and 2006-2010) were reviewed including the demographic and clinical data and discharge medications. The data were gathered from a total of 207 patients (95 in 1990s and 112 in 2000s). Results The frequency in use of atypical antipsychotics (p < 0.01), antidepressants (p < 0.05), beta-blockers (p < 0.01), and benzodiazepine (p < 0.01) was significantly higher in 2000s. Anticholinergic drugs were less likely used in 2000s (p < 0.01). We did not find significant differences in the equivalent dose of antipsychotic drugs, the use of mood stabilizers and cholinergic drugs between two time frames. Conclusions Increased proportion of atypical antipsychotics and decreased use of anti-parkinsonian drugs are in line with literature. Our results show that more diverse classes of psychotic medications are used for schizophrenia in recent years. It is likely that psychiatrists are becoming more conscious of negative symptoms, anxiety, and depression in the pharmacotherapy of schizophrenia as well as positive symptoms of the illness.
