REVIEW ER 'S CONCLUSIONS We found no significant evidence to support the use of clotiapine rather than other ' st and ard ' or ' non-st and ard ' treatments for the management of  acute psychotic illness .
BACKGROUND Acute psychotic illness , especially when associated with agitated or violent behaviour , requires urgent pharmacological tranquillisation or sedation .
Clotiapine , a dibenzothiazepine neuroleptic , is being used for this purpose in several countries .
OBJECTIVES To estimate the effects of clotiapine when compared to other ' st and ard ' or ' non-st and ard ' treatments of acute psychotic illness in controlling disturbed behaviour and reducing psychotic symptoms .
A RATING SCALE FOR EXTRAPYRAMIDAL SIDE EFFECTS
A modification of an earlier rating scale for extrapyramidal system disturbance is described , and evidence for the validity and reliability of the scale is presented . The usefulness of the scale in studies of neuroleptic drugs is discussed . By its application it is possible to quantify extrapyramidal side effects and to separate them into four principal factors
