Abstract

The present open-label study assessed the efficacy of zuclopenthixol, an thioxanthene neuroleptic with combined dopamine receptors (D1/D2) antagonist activity, in the treatment of severe behavioral disturbances in mentally retarded children and adolescents. A sample of 15 (11 males, 4 females) mentally retarded children and adolescents, ages 5-18 years (12.2±2.3 [mean±SD] years), all exhibiting severe behavioral disturbances, was evaluated. The 12-week zuclopenthixol treatment (up to 26 mg/day) was initiated after a week's washout from previous antipsychotic agents. An assessment of the behavioral disturbances was performed using the 14-item Checklist for Behavior Problems Involving Limited or No Social Awareness (CBP-NSA). The Udvalg for kliniske undersøgelser (UKU) Side Effect Rating Scale was used to assess the pharmacologic side effects. Results show a significant reduction in total CBP-NSA scores and in individual items such as hyperactivity, aggressive behavior, and temper tantrums (p<0.001 for each). It seems that zuclopenthixol monotherapy is effective and well tolerated in the treatment of severe behavioral disturbances in mentally retarded children and adolescents. Double-blind, placebo-controlled studies are needed before definitive conclusions can be drawn regarding the efficacy and safety of zuclopenthixol for this population.
