MetadataShow full item record
To compare the efficacy and tolerability of Fluvoxamine and Venlafaxine in patients with Obsessive Compulsive Disorder (OCD). A total of 50 newly diagnosed patients with OCD were randomly assigned 25 each to receive either fluvoxamine (Selective serotonin reuptake inhibitor) or venlafaxine (selective serotonin norepinephrine reuptake inhibitor). Primary efficacy was assessed by the change from baseline on the Yale Brown Obsessive Compulsive Scale (Y-BOCS). The Clinical Global Impression Improvement Scale (CGI-S) was used to measure symptom improvement. Each patient was followed as a single visit in a week wise manner following the order; Week0, Week 1, Week 2, Week 4, Week 6, Week 8, Week 12 and Week 16. At each visit if any adverse reaction to either of the drugs experienced by the patient were noted. Treatment group comparison of patients, demographic characteristics and baseline severity measurements were done using a Chi square test and the student t-test. Statistical significance was defined as a 2-sided p value ≤ 0.05. Both drugs showed significant reduction in the OCD symptoms as measured on the Y-BOC Scale over the 16-week follow up. When compared fluvoxamine showed statistically significant reduction in overall YBOC score and Obsessive mean score. The difference in compulsive mean score was not significant in the two treatment groups. Fluvoxamine is more efficacious than Venlafaxine in the treatment of OCD.
