In acute treatment , the pooled mean change score of the Aberrant Behavior Checklist for irritability subscale ( ABC-I ) and response rate for the risperidone-treated group had a greater significance than that of the placebo-treated group .
According to the discontinuation phase , the overall pooled relapse rate of the risperidone-treated group was significantly less than that of the placebo-treated group .
The rates of pooled overall discontinuation and discontinuation due to adverse events rates were not different between the two groups in acute and long-term treatments .
Conclusion In relation to the current systematic review , risperidone is efficacious in the treatment of symptoms in children and adolescents with ASD .
Although its acceptability is comparable to placebo , treatment with risperidone is well tolerated in children and adolescents with ASD
Background Various clinical trials suggested that risperidone was beneficial in the treatment of autism spectrum disorder ( ASD ) in children and adolescents .
Objective The aim of this systematic review was to determine the efficacy , acceptability and tolerability of risperidone in the treatment of children and adolescents with ASD .
Risperidone in the Treatment of Disruptive Behavioral Symptoms in Children With Autistic and Other Pervasive Developmental Disorders
Objective . To investigate the efficacy and safety of risperidone for the treatment of disruptive behavioral symptoms in children with autism and other pervasive developmental disorders ( PDD ) . Methods . In this 8-week , r and omized , double-blind , placebo-controlled trial , risperidone/placebo solution ( 0.01–0.06 mg/kg/day ) was administered to 79 children who were aged 5 to 12 years and had PDD . Behavioral symptoms were assessed using the Aberrant Behavior Checklist ( ABC ) , Nisonger Child Behavior Rating Form , and Clinical Global Impression-Change . Safety assessment s included vital signs , electrocardiogram , extrapyramidal symptoms , adverse events , and laboratory tests . Results . Subjects who were taking risperidone ( mean dosage : 0.04 mg/kg/day ; 1.17 mg/day ) experienced a significantly greater mean decrease on the irritability subscale of the ABC ( primary endpoint ) compared with those who were taking placebo . By study endpoint , risperidone-treated subjects exhibited a 64 % improvement over baseline in the irritability score almost double that of placebo-treated subjects ( 31 % ) . Risperidone-treated subjects also exhibited significantly greater decreases on the other 4 subscales of the ABC ; on the conduct problem , insecure/anxious , hyperactive , and overly sensitive subscales of the Nisonger Child Behavior Rating Form ( parent version ) ; and on the Visual Analog Scale of the most troublesome symptom . More risperidone-treated subjects ( 87 % ) showed global improvement in their condition compared with the placebo group ( 40 % ) . Somnolence , the most frequently reported adverse event , was noted in 72.5 % versus 7.7 % of subjects ( risperidone vs placebo ) and seemed manageable with dose/dose-schedule modification . Risperidone-treated subjects experienced statistically significantly greater increases in weight ( 2.7 vs 1.0 kg ) , pulse rate , and systolic blood pressure . Extrapyramidal symptoms scores were comparable between groups . Conclusions . Risperidone was well tolerated and efficacious in treating behavioral symptoms associated with PDD in children
