title: Twice-weekly aripiprazole for treating children and adolescents with tic disorder, a randomized controlled clinical trial.
abstract: OBJECTIVE
  Treating tic disorder is challenging. No trial has ever examined whether twice weekly aripiprazole is effective for treating tic disorders.
  
  
  METHODS
  Participants of this 8-week randomized controlled parallel-group clinical trial were a clinical sample of 36 children and adolescents with tic disorder. Yale global tic severity scale was used to assess the outcome. Both groups received daily dosage of aripiprazole for the first 14 days. Then, one group received daily dose of aripiprazole while the other group received twice weekly dosage of aripiprazole for the next 46 days. The patients were assessed at baseline, week 2, 4, and 8.
  
  
  RESULTS
  Tic scores decreased in both group significantly 22.8 (18.5) versus 22.0 (11.6). Moreover, there was no between group difference. The final mean (SD) score of motor and vocal tics in the group treated with daily treatment was not significantly different from the twice weekly group (Cohen's d = 0.36). The odds ratios for sedation and increased appetite were 3.05 and 3, respectively.
  
  
  CONCLUSIONS
  For the first time, current findings support that twice weekly aripiprazole efficacy was not different from that of daily treatment. The rate of drowsiness in the twice weekly treatment group was less than that of the daily treatment group. This trial was registered at http://www.irct.ir. The registration number of this trial was: IRCT201312263930N32. http://www.irct.ir/searchresult.php?id=3930&number=32.
