Risperidone Augmentation of Paroxetine in a Case of Severe, Treatment-Refractory Obsessive-Compulsive Disorder Without Comorbid Psychopathology

J Clin Psychiatry 1999;60(1):55-56 [letter]

Letter to the Editor

Sir: Risperidone is an atypical antipsychotic drug distinguished from conventional neuroleptics by its antagonism of serotonin receptors of the 5-HT2A and 5-HT7 subtypes while having a similar affinity for dopamine D2 receptors. The novel pharmacologic profile of risperidone suggests the possibility of other therapeutic applications, particularly in disorders putatively associated with abnormal central serotonergic function. Obsessive-compulsive disorder (OCD) is such a disorder, and recent reports suggest that risperidone may be an effective adjunct to treatment of OCD with selective serotonin reuptake inhibitors (SSRIs).
