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 .
Haloperidol in the treatment of infantile autism: effects on learning and behavioral symptoms.
In this double-blind , placebo-controlled study the administration of haloperidol result ed in significant decreases in behavioral symptoms and in general clinical improvement in 40 autistic children ages 2.33 to 6.92 years .  Haloperidol also produced greater facilitation and retention of discrimination learning in the laboratory . No adverse effects were observed at therapeutic doses , which ranged from 0.5 to 3.0 mg/day or 0.019 to 0.217 mg/kg per day
