Pilot Study B: In an open label study of 21 OCD patients who responded poorly to at least 12 weeks of SSRI treatment, 12 of these patients, or 57 percent, responded with a 25 percent or greater reduction in Y-BOCS. The average Y-BOCS score in this responder group improved 44 percent from baseline at 12 weeks. Four weeks after discontinuation of low dose ondansetron treatment, the average Y-BOCS score of the responder group worsened 38 percent from the end of treatment score. None of the treated patients experienced symptom exacerbation or significant adverse effects. (Reference: S. Pallanti, S. Bernardi, E.

About OCD Obsessive compulsive disorder (OCD) is characterized by a pattern of unwanted and intrusive thoughts that cause distress and consequent repetitive behaviors aimed at reducing this distress. OCD affects approximately 1 to 2 percent of the U.S. adult population and can significantly impair the lives of patients and their families. Greater social impairment has been reported in patients with OCD as compared to those with social anxiety or panic disorder. It is believed that the overall degree of impairment caused by OCD is comparable to that experienced by patients who suffer with schizophrenia.
SSRIs, including Prozac® (fluoxetine), Luvox® (fluvoxamine), Paxil® (paroxetine), and Zoloft® (sertraline), and the tricyclic agent, clomipramine, are the only approved medications for OCD. While these medications are used as first-line treatments for OCD, approximately 40 percent to 60 percent of OCD patients do not respond adequately, and there is no FDA-approved therapy for this group of patients.
