Abstract

Objective: To evaluate the efficacy of pindolol augmentation in treatment-resistant obsessive compulsive disorder (OCD) patients who were unsuccessfully treated with serotonin reuptake inhibitors. Method: Fourteen treatment-resistant OCD patients were treated with paroxetine for 17.4±2.1 weeks up to 60 mg/d after they failed at least two other serotonin reuptake inhibitor trials. The patients, who did not respond to open-label paroxetine treatment, were assigned to a double-blind, placebo-controlled pindolol (2.5 mgx3/d) augmentation. All the subjects were evaluated biweekly for a six-week period with the Yale-Brown Obsessive Compulsive Scale (Y-BOCS), Hamilton Anxiety Scale (HAM-Anx), and Montgomery Asberg Depression Rating Scale (MADRS). Data was analyzed by paired t-test, and ANOVA with repeated measures. Results: Pindolol augmentation to paroxetine (n=8) as compared to placebo augmentation (n=6), was associated with a significant (P<0.01) improvement in Y-BOCS as measured by paired t-test after the fourth week of the treatment and by ANOVA with repeated measures (df: 4.9, f: 3,3, P<0.006). Although no significant differences were found between placebo and pindolol groups on HAM-Anx and MADRS, a trend for improvement in the pindolol group was noted. Conclusions: The results of our study demonstrated that pindolol may augment the therapeutic effect of paroxetine in treatment-resistant OCD patients. (C) 2000 Elsevier Science B.V.
