Two trials examined olanzapine and found no difference in the primary outcome ( response to treatment ) and most other efficacy-related outcomes but it was associated with more weight gain than monotherapy with antidepressants .
There were also some beneficial effects of quetiapine in terms of anxiety or depressive symptoms .
BACKGROUND Obsessive compulsive disorder ( OCD ) is a psychiatric disorder which has been shown to affect 2 to 3.5 % of people during their lifetimes .
Inadequate response occurs in 40 % to 60 % of people that are prescribed first line pharmaceutical treatments ( selective serotonin reuptake inhibitors ( SSRIs ) ) .
To date not much is known about the efficacy and adverse effects of second-generation antipsychotic drugs ( SGAs ) in people suffering from OCD .
OBJECTIVES To evaluate the effects of SGAs ( monotherapy or add on ) compared with placebo or other forms of pharmaceutical treatment for people with OCD .
Adding quetiapine to SRI in treatment-resistant obsessive–compulsive disorder: a randomized controlled treatment study
This study aim ed to determine the efficacy and tolerability of adding quetiapine to a serotonin reuptake inhibitor in treatment-resistant obsessive – compulsive disorder ( OCD ) . Twenty-one adult treatment-resistant OCD patients were r and omized to 16 weeks of augmentation with either quetiapine ( n=11 ) or placebo ( n=10 ) . Patients with significant comorbidities , including tic-spectrum disorders , were not included . The treatment was well tolerated , with only one premature dropout in each treatment-group . The primary analysis showed that individuals in the quetiapine-treated group showed a 14 % mean improvement in baseline Yale – Brown Obsessive – Compulsive Scale scores at study endpoint compared with a 6 % improvement in those treated with placebo , but this difference did not reach statistical significance ( F<1 ) . Three patients treated with quetiapine met criteria for clinical response , compared to one patient who was treated with placebo . Larger studies are needed to explore the efficacy of second generation antipsychotics , such as quetiapine , when used as adjunct treatment in resistant OCD
