Aripiprazole is a novel atypical antipsychotic that is approved in the US for use in adolescents with schizophrenia. In adolescents with schizophrenia, oral aripiprazole 10 or 30 mg/day lead to significantly greater reductions than placebo in the Positive and Negative Syndrome Scale (PANSS) total score from baseline to 6 weeks, according to findings from a randomized, double-blind, multicenter trial (n = 302). In addition, aripiprazole 10 or 30 mg/day recipients had significantly greater improvements in the PANSS positive subscale and Clinical global Impression-Severity and -Improvement scale scores than placebo recipients, and a significantly greater improvement in the PANSS negative subscale score was seen with aripiprazole 10 mg/day than with placebo. Aripiprazole was generally well tolerated in adolescents with schizophrenia, with most adverse events being of mild to moderate severity. Clinically significant weight gain (> or = 7% as defined by the US FDA) occurred in 4.0% of aripiprazole 10 mg/day recipients, 5.2% of aripiprazole 30 mg/day recipients, and 1% of placebo recipients. The mean weight change was significantly different in aripiprazole and placebo recipients (0, +2, and -0.8 kg in aripiprazole 10 mg/day, aripiprazole 30 mg/day, and placebo recipients, respectively).

    • "APZ is indicated in the USA for acute and maintenance treatment of schizophrenia in adolescents (13–17 years of age) and acute treatment of bipolar I disorder in children (10–17 years of age) as monotherapy and as an adjunctive to lithium or valproate. It is also indicated for use in treating irritability associated with autistic disorder in pediatric patients (6–17 years of age) [28–32]. Aparasu et al. [33] examined patterns and determinants of antipsychotic prescribing in children and adolescents receiving outpatient care in the USA. "

    ABSTRACT: Aripiprazole (APZ) has a unique pharmacological profile, as a partial agonist at the dopamine D2 and serotonin 5HT1A receptors and an antagonist at the serotonin 5HT2A receptor; this drug has few side effects (such as extrapyramidal syndrome, hyperprolactinemia, weight gain, metabolic disorders, and sedation) which are typical problems with other antipsychotic drugs. Due to its high tolerability, it is possible to safely administer it to children and adolescents. Efficacy and tolerability of APZ in children and adolescents have been well demonstrated in many clinical studies, which supported approvals granted by the US Food and Drug Administration (FDA) for schizophrenia, bipolar diseases, and irritability associated with autistic disorder in children and adolescents. APZ is expected to exert sedative, anti-depressive, and anti-anxiety effects, and stabilize emotion. APZ is an antipsychotic drug which could be useful for a wider spectrum of psychiatric disorders in children and adolescents. There is little risk of deterioration (such as disinhibition and acting out) and rapid stabilization is easy to achieve in children and adolescents without definitive diagnoses or with a combination of more than one spectrum of disorders. The effectiveness of APZ in children and adolescents is reviewed and discussed, given its pharmacological profile and the outcomes of various clinical studies. However, randomized or blind studies are still limited, and the majority of reports referenced here are open-label studies and case reports. Conclusions drawn from such studies must be evaluated with caution, and a further accumulation of controlled studies is thus needed.

    ABSTRACT: Objective: The aim of this case series was to assess the effectiveness and tol-erability of aripiprazole in Korean children and adolescents with early-onset schizophrenia spectrum (EOSS) disorder. Methods: The medical records of aripiprazole-treated patients with EOSS were retrospectively reviewed. Changes in illness severity were measured using the Clinical Global Impression-Severity of Illness (CGI-S) and Clinical Global Impression-Improvement (CGI-I) scales. Results: Data from 22 children and adolescents were included (12 girls, 10 boys; mean [SD] age, 14.0 [2.4] years). The mean (SD) dosage of aripiprazole was 19.8 (9.4) mg/d (median, 18.7 mg/d; mode, 15, 30 mg/d), and the range of treatment duration was 21 to 838 days. Mean (SD) CGI-S score improved significantly from baseline to end point (from 5.7 [0.7] to 4.3 [1.4]; P < 0.001). Based on changes in chart-extracted CGI-I scores, significantly greater improvement was associated with negative symptoms compared with positive symptoms (U = 25.5; P = 0.028; r = -0.47). Aripiprazole was discontinued due to insufficient effect in 5 patients (22.7%) and treatment-emergent adverse events in 3 patients (13.6%). Conclusion: The results from this small study suggest that aripiprazole was moderately effective in reducing psychotic symptoms in these Korean children and adolescents with EOSS.

    ABSTRACT: The prescription of antipsychotic medication in children and adolescents (<18 years of age) has increased immensely for a wide range of disorders including psychoses, bipolar disorder, conduct disorder, pervasive developmental disorder and obsessive-compulsive disorder. This has led to some concerns particularly as the evidence base in some areas is not strong, and antipsychotic medication - both first generation (FGA) and second generation (SGA) - is associated with considerable side-effects. Evidence from an increasing number of randomised controlled trials (RCTs) points to therapeutic efficacy with moderate to large effect sizes. However, some RCTs have a small number of participants, are of short duration, and many are industry funded. The use of antipsychotics alongside psychosocial interventions can be recommended in certain disorders, provided there is continued, careful monitoring. It is important to note, however, that for many conditions the use of antipsychotics is not licensed in the UK.
