OBJECTIVE: Our primary objective was to evaluate the effectiveness and tolerability of intramuscular ziprasidone for impulsivity and agitation in psychiatrically hospitalized children and adolescents. Our secondary objective was to examine demographic and clinical factors associated with treatment response. METHOD: We conducted a retrospective chart review of children and adolescents admitted to Cincinnati Children's Hospital Medical Center (CCHMC) psychiatric units between January 1, 2002, and July 11, 2005, who received intramuscular ziprasidone. Medical records were reviewed to determine demographic and clinical information as well as tolerability and effectiveness of ziprasidone. The Behavioral Activity Rating Scale (BARS) was used retrospectively to assess clinical response. Regression analyses were performed to evaluate the effect of demographic factors (age, gender, and ethnicity) and primary psychiatric diagnoses on treatment response. Electrocardiogram (ECG) data was inadequate. RESULTS: Fifty nine children and adolescents received a total of 77 injections of intramuscular ziprasidone for acute agitation. The mean +/- SD BARS score decreased from 6.5 +/- 0.7 to 3.1 +/- 1.3. The most common side effect was drowsiness or falling asleep (n = 46, 60%). Three (4%) could not be roused after the injection. CONCLUSIONS: Intramuscular ziprasidone may be helpful for agitation but often caused oversedation. Safety data, including ECGs, is needed in controlled prospective studies.
