This report presents preliminary findings in an ongoing double-blind, placebo-controlled study of the safety and efficacy of haloperidol in hospitalized schizophrenic children. The subjects are diagnosed schizophrenic by DSM-III-R criteria and admitted to the Bellevue Hospital Children's Inpatient Psychiatric Unit. The study is 10 weeks in duration and employs a crossover design. After a 2-week placebo baseline period, the subjects enter double-blind treatment for 8 weeks, by random assignment receiving either haloperidol for 4 weeks followed by placebo for 4 weeks, or alternatively, placebo for 4 weeks followed by haloperidol for 4 weeks. Dosage, regulated individually, ranges from 0.5 to 10.0 mg/day. To date, of an anticipated 20 subjects, 12 have completed the study. These children, 9 boys and 3 girls, were ages 5.5 to 11.75 years upon study entry. Haloperidol was superior to placebo for reduction of target symptoms with optimal haloperidol dose of 0.5 to 3.5 mg/day (0.02-0.12 mg/kg/day).
