Pipothiazine palmitate in the management of aggressive mentally handicapped patients
DM Lynch, CL Eliatamby and AA Anderson
The efficacy of intramuscular pipothiazine palmitate (PP) in the management
of aggressive mentally handicapped patients was examined in a double-blind,
placebo-controlled, cross-over study, in which 30 patients received each
treatment for 13 weeks. A target symptom scale of aggressiveness (TSA) and
a clinical global impression scale of efficacy were rated at monthly
intervals, and an extra-pyramidal side- effects scale weekly. The patients
showed marked improvement during treatment with PP, which was assessed as
superior to placebo. Individual and total TSA scores were also reduced
compared to placebo.
