The side effects ‘ EPS ’ , ‘ parkinsonism ’ , and ‘ tremor ’ were significantly more common in children and adolescents treated with aripiprazole than in those treated with placebo .
Conclusion Our meta- analysis provides evidence for a non-negligible incidence of acute EPS in children and adolescents treated with aripiprazole .
Background Both the US FDA and the European Medicines Agency ( EMA ) have approved aripiprazole for use in adolescents for specific indications .
Given the assumed favorable side-effect profile of aripiprazole , its use in children and adolescents has increased for both official and off-label indications ( anxiety disorders , eating disorders , personality disorders ) .
However , several cases of children and adolescents with new-onset  extrapyramidal symptoms ( EPS )  after commencing treatment with aripiprazole have been reported , and a more systematic appraisal of this possible risk is lacking .
Objective We conducted a systematic review and a meta- analysis to assess the evidence for acute EPS ( acute dystonia , akathisia , Parkinsonism ) associated with the use of aripiprazole in children and adolescents .
Aripiprazole in the Treatment of Irritability in Children and Adolescents With Autistic Disorder
OBJECTIVE : The objective of this study was to evaluate short-term efficacy and safety of aripiprazole in the treatment of irritability in children and adolescents with autistic disorder who were manifesting behaviors such as tantrums , aggression , self-injurious behavior , or a combination of these . METHODS : This 8-week , double-blind , r and omized , placebo-controlled , parallel-group study was conducted of children and adolescents ( aged 6–17 years ) with autistic disorder . Patients were r and omly assigned ( 1:1 ) to flexibly dosed aripiprazole ( target dosage : 5 , 10 , or 15 mg/day ) or placebo . Efficacy outcome measures included the Aberrant Behavior Checklist irritability subscale and the Clinical Global Impression – Improvement score ( CGI-I ) . Safety and tolerability were also assessed . RESULTS : Ninety-eight patients were r and omly assigned to receive placebo ( n = 51 ) or aripiprazole ( n = 47 ) . Mean improvement in Aberrant Behavior Checklist irritability subscale score was significantly greater with aripiprazole than with placebo from week 1 through week 8 . Aripiprazole demonstrated significantly greater global improvements than placebo , as assessed by the mean CGI-I score from week 1 through week 8 ; however , clinical ly significant residual symptoms may still persist for some patients . Discontinuation rates as a result of adverse events ( AEs ) were 10.6 % for aripiprazole and 5.9 % for placebo . Extrapyramidal symptom-related AE rates were 14.9 % for aripiprazole and 8.0 % for placebo . No serious AEs were reported . Mean weight gain was 2.0 kg on aripiprazole and 0.8 kg on placebo at week 8 . CONCLUSIONS : Aripiprazole was efficacious in children and adolescents with irritability associated with autistic disorder and was generally safe and well tolerated
