Buspirone treatment of psychiatrically hospitalized prepubertal children with symptoms of anxiety and moderately severe aggression.

Overview

Open-label buspirone was studied in 25 prepubertal psychiatric inpatients (age 8.0 +/- 1.8 years, 76% boys) presenting with anxiety symptoms and moderately aggressive behavior. Patients with severe aggression, requiring rapid treatment with mood stabilizers or neuroleptics, were excluded. A 3-week titration (maximum 50 mg daily) preceded a 6-week maintenance phase at optimal dose. Buspirone was discontinued in 6 children (25%): 4 developed increased aggression and agitation, and 2 developed euphoric mania. For the 19 patients who completed the study, mean optimal dose was 28 mg daily. Among completers, depressive symptoms were reduced 52% by Week 6 on Children's Depression Inventory (p < or = 0.001). Decreased aggressivity was reflected in a 29% reduction on Measure of Aggression, Violence, and Rage in Children [MAVRIC] ratings (p < or = 0.02) and in 86% less time in seclusion or physical restraints (p < or = 0.02). Clinical Global Assessment scores improved (CGAS 41 vs. 54, p < or = 0.01). Only 3 children improved sufficiently to continue buspirone after the study. Residual aggressivity and global functioning remained problematic. Buspirone may pose behavioral risks in treating moderate aggressivity in 24% of children with anxiety; in the others, the therapeutic effects on aggression, anxiety, and depression were limited but significant.
