Summary of Child and Adolescent Studies Comparing Side Effects in First-Generation Antipsychotics (FGAs) and Second-Generation Antipsychotics (SGAs)
| Study | Journal | Type of Study | Findings |
| Correll et al,7 2009 | Journal of the American Medical Association | Large (N = 272), nonrandomized, multisite, controlled, 12-week trial examining cardiometabolic risk of SGAs in treatment-naive youth (aged 4–19 y) (SATIETY) | Aripiprazole, olanzapine, quetiapine, and risperidone were all associated with rapid and significant increases in body composition, but metabolic changes were less uniform. Actual metabolic syndrome and diabetes rarely developed |
| Sikich et al,16 2008 | American Journal of Psychiatry | Small (N = 119), 8-week, randomized trial comparing efficacy and safety of olanzapine and risperidone with molindone in treatment of early-onset schizophrenia and schizoaffective disorder (TEOSS) | No significant difference in response rates (molindone: 50%, olanzapine: 34%, risperidone: 46%). Olanzapine and risperidone associated with significantly greater weight gain (random assignment to olanzapine was discontinued). Molindone group had more self-reported akathisia |
| Fleischhaker et al,17 2008 | Journal of Neural Transmission | Small (N = 33), nonrandomized trial looking at weight and BMI for patients treated with clozapine, olanzapine, and risperidone over 45 wk | All groups experienced significant weight gain. Risperidone group reached weight gain plateau at 25–29 wk |
| Wonodi et al,18 2007 | Movement Disorders | Small (N = 118), nonrandomized trial with healthy control group (35 subjects) looking at tardive dyskinesia in children receiving antipsychotics | Nine percent exhibited tardive dyskinesia (11 of 118, including 5 of 81 receiving SGAs only) over more than 2 y |
| Sikich et al,3 2004 | Neuropsychopharmacology | Small (N = 50), 8-week, double-blind, randomized controlled trial comparing acute antipsychotic effect size and side effect propensity of risperidone and olanzapine to haloperidol in youth (aged 8–19 y) | Risperidone, olanzapine, and haloperidol were similarly effective; however, EPS were significant in all groups, as was weight gain |
