title: Ramelteon for insomnia in two youths with autistic disorder.
abstract: OBJECTIVE
  The aim of this study was to report preliminary data on the effectiveness and tolerability of ramelteon for the treatment of insomnia in youth with autistic disorder (autism).
  
  
  METHODS
  Two youths, ages 7 and 18 years, with autism and significant insomnia characterized by problems with sleep onset and maintenance received an open-label trial of ramelteon (4-8 mg) over a duration of 16-18 weeks.
  
  
  RESULTS
  Target symptoms of delayed sleep onset and/or frequent nocturnal awakening improved significantly, as determined by Clinical Global Impressions-Improvement (CGI-I) scale ratings of either "much improved" or "very much improved." Ramelteon was well tolerated. No daytime sedation was reported.
  
  
  CONCLUSIONS
  This case report illustrates the potential effectiveness and tolerability of ramelteon for sleep disturbances in 2 patients with autism. Further research is needed to verify its safety, tolerability, and efficacy in children and adolescents with autism.
