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 .
A multiple-center, randomized, double-blind, placebo-controlled study of oral aripiprazole for treatment of adolescents with schizophrenia.
OBJECTIVE Aripiprazole is a dopamine partial agonist approved for use in adults for short- and long-term treatment of schizophrenia and bipolar disorder . This study was design ed to examine the acute efficacy , safety , and tolerability of aripiprazole for adolescents with schizophrenia . METHOD This was a 6-week multicenter , double-blind , r and omized , placebo-controlled trial . Subjects 13 to 17 years old with a DSM-IV diagnosis of schizophrenia and a Positive and Negative Syndrome Scale ( PANSS ) total score of 70 or more were r and omly assigned ( 1:1:1 ratio ) to placebo or 10 or 30 mg/day of aripiprazole . The primary endpoint was mean change from baseline to endpoint ( last observation carried forward ) in PANSS total score . Assessment s of safety and tolerability included spontaneously reported adverse events , extrapyramidal symptom scores , serum prolactin concentration , body weight , and metabolic measures . RESULTS Of 302 patients , 85 % completed the 6-week study . The mean baseline PANSS score was 94.1 . At the end of the study , both aripiprazole doses showed statistically significant differences from placebo in reduction in PANSS total score . Adverse events occurring in more than 5 % of either aripiprazole group and with a combined incidence at least twice the rate for placebo were extrapyramidal disorder , somnolence , and tremor . Mean changes in prolactin were -8.45 , -11.93 , and -15.14 ng/ml for placebo and 10 mg and 30 mg of aripirazole , respectively . Mean body weight changes were -0.8 , 0.0 , and 0.2 kg for placebo and 10 mg and 30 mg of aripiprazole , respectively . CONCLUSION Both 10- and 30-mg/day doses of aripiprazole were superior to placebo in the acute treatment of adolescents with schizophrenia .  Aripiprazole was generally well tolerated
