title: On the pharmacotherapy of obsessive-compulsive disorder: is a consensus possible?
abstract: OBJECTIVE
  To examine the efficacy and tolerability of clomipramine compared with the selective serotonin reuptake inhibitors (SSRIs) in the treatment of obsessive-compulsive disorder (OCD), bearing in mind the recent Expert Consensus Guidelines recommendation to use clomipramine after 2 to 3 failed SSRI trials.
  
  
  METHODS
  The literature on the pharmacotherapy of OCD was critically examined.
  
  
  RESULTS
  The available research evidence is not conclusive but suggests that clomipramine possesses greater anti-obsessional efficacy than do the SSRIs. In addition, when clomipramine is presented to patients in a positive way, and properly used in small initial doses with gradual increases, it seems to be tolerated as well as the SSRIs.
  
  
  CONCLUSIONS
  Recently expressed opinions that clomipramine should be used to treat OCD after 2 to 3 failed SSRI trials are not supported by research evidence. Both clomipramine and the SSRIs may be used as first-line treatments for OCD.
