Effectiveness of zuclopenthixol compared with haloperidol in the treatment of behavioural disturbances in learning disabled patients.
BACKGROUND
We compared the efficacy of two neuroleptics with different receptor profiles (zuclopenthixol and haloperidol) in learning disabled patients with behavioural disturbance.


METHODS
A double-blind crossover study (2 x 8 weeks; n = 34), interrupted by a two-week single-blind washout period, was employed. Assessments included the Schedule for Handicaps, Behaviour, and Skills (SHBS) and Clinical Global Impression (CGI).


RESULTS
The SHBS score was significantly reduced for the zuclopenthixol cohort only. End-point analysis between the two drugs also showed an enhanced effect for zuclopenthixol over haloperidol. CGI scores did not reveal significant differences between the two drugs.


CONCLUSIONS
Zuclopenthixol may be superior to haloperidol for the treatment of behavioural disturbances in mentally retarded subjects.
