Abstract:
OBJECTIVE: The purpose of this study was to examine the pharmacological treatment patterns and clinical responses in inpatients and/or outpatients with obsessive compulsive disorder (OCD) at a university hospital. METHODS: A total of 71 OCD patients were included and followed during the first 4 months, first year and second year from 1998. The patterns of medication use and clinical responses according to the Yale-Brown obsessive-compulsive scale (Y-BOCS) were analyzed descriptively in this period. RESULTS: During the first 4 months, 26.7% of the patients underwent monotherapy in which most of the drugs were serotonin reuptake inhibitors (SRIs). Therapy with two or more drugs was administered in 66.6% of the patients and combination drugs with SRIs were atypical antipsychotics and clonazepam. The clinical response rate using Y-BOCS was 24.0% compared with baseline score. During the first year, the frequency of the monotherapy decreased to 6.5%, while that of therapy with two or more drugs increased to 80.6% (two and three drug frequencies were 35.3%, and 32.3%, respectively). The clinical response rate was 26.4% during this period. During the second year, the frequency of the monotherapy was 25% and that of multidrug therapy was 70.8% (two and three drug frequencies were 20.8%, and 45.8%, respectively). The clinical response rate was 39.3% compared with baseline score. CONCLUSIONS: In this study, the frequency of the combination therapy was relatively high compared with SRI monotherapy during the first 4 months and it increased further during the first year. The combination therapy was maintained without change of SRI dosage during the second year. Most of the drugs used in the combination therapy were atypical antipsychotics and clonazepam.
