5. Study Description

Brief Summary
This will be a controlled, randomized, double-blind and double-dummy study on the treatment augmentation strategy for obsessive compulsive disorder patients non-respondent to first line pharmacological treatment. The investigators will compare: fluoxetine maintenance at maximum dosage for additional 12 weeks; the association of fluoxetine with quetiapine; and the association of fluoxetine with clomipramine.
Detailed Description
Arm 1: SSRI (Fluoxetine 40mg* once a day) + Clomipramine 75mg* once a day. Arm 2: SSRI (Fluoxetine 40mg* once a day) + Quetiapine 200mg* once a day. Arm 3: SSRI (Fluoxetine 80mg* once a day) + Placebo once a day. *or maximum tolerated dose We hypothesize that quetiapine and clomipramine will be effective augmentation strategies for resistant OCD patients in comparison to placebo.
