Obsessive-compulsive disorder (OCD) is one of the most common and disabling psychiatric disorders. Treatment with selective serotonin reuptake inhibitors (SSRIs) shows significant improvement; however, residual symptoms remain in most patients despite continued treatment. For partial or nonresponding patients to multiple SSRIs, augmentation strategies are usually recommended. Here we present a consecutive sample of patients with resistant OCD treated with amisulpride augmentation to SSRIs. Methods We present 10 patients (5 males, 5 females) experiencing resistant OCD. Subjects were treated openly for 6 weeks with amisulpride 200 mg/d as add-on, excluding 1 patient who was treated with only 100 mg/d due to acute extrapyramidal adverse effect on a larger dose. Efficacy was assessed at baseline and after 6 weeks of treatment using the Yale-Brown Obsessive-Compulsive Scale, Clinical Global Impression-Severity, and Clinical Global Impression-Improvement. RESULTS: The treatment was generally well tolerated without serious events. In all patients, average Yale-Brown Obsessive-Compulsive Scale scores diminished from 25.3 ± 5.96 points at baseline to 12.2 ± 5.98 at the sixth week (P < 0.0005). Of 10 patients, 7 had significant and partial improvement, and 3 patients did not demonstrate any improvement. CONCLUSIONS: Treatment-resistant OCD patients positively responded and well tolerated amisulpride add-on to their ongoing regular pharmacotherapy. This case series demonstrates that amisulpride could be a promising optional therapy for patients who have resistant OCD. Further randomized controlled studies are necessary.
