In a double-blind crossover placebo controlled trial the effectivity of piracetam in neuroleptic-induced extrapyramidal side effects was confirmed. 40 psychotic patients treated with neuroleptics in an average daily dose equal to 600 mg of chlorpromazine were included in this study. Akathisia, tremor, muscle rigidity and dyskinesia were evaluated on a 4-point scale. The patients were randomly divided into two subgroups--40 g of piracetam or placebo from identic ampoules were given i.v. with a crossover readministration after 60 min. The intensity of the extrapyramidal side effects was evaluated at 30-min intervals during 2 h. Piracetam was proved to be significantly effective in both subgroups, the onset of its action being between 30 and 60 min after i.v. administration. Possible interpretations of the observed piracetam effectivity are considered. Further trials with piracetam in neurologic complications during neuroleptic treatment, tardive dyskinesia included, are suggested.

Palatal tremor (PT) is a rhythmic movement of the soft palate that often causes an ear click. PT can be symptomatic (SPT) or essential (EPT). The symptomatic form usually occurs in adults and the essential form mainly occurs in children. Several different treatments for EPT in children appear in the literature with variable reported efficacy. This report details four paediatric patients with EPT (three males, one female; mean age 6y 4mo [SD 6mo]; age at onset 6-7y) treated with piracetam (2-oxo-1-pyrrolidine acetamide). Piracetam was used to treat EPT because of its antimyoclonic properties. All children showed a good response to doses of 100 to 300mg/kg/day. EPT relapsed on withdrawal of piracetam and remitted on reintroduction. Piracetam's effect on EPT was sustained. It is concluded that piracetam is an effective drug for the treatment of EPT in children.
