When haloperidol and midazolam were compared with olanzapine , there was some evidence the combination was superior in terms of improvement , sedation and behaviour .
There were relatively little good data and most trials are too small to highlight differences in either positive or negative effects .
Adding a benzodiazepine to other drugs does not seem to confer clear advantage and has potential for adding unnecessary adverse effects .
Sole use of older antipsychotics unaccompanied by anticholinergic drugs seems difficult to justify .
BACKGROUND Acute psychotic illness , especially when associated with agitated or violent behaviour , can require urgent pharmacological tranquillisation or sedation .
In several countries , clinicians often use benzodiazepines ( either alone or in combination with antipsychotics ) for this outcome .
OBJECTIVES To estimate the effects of benzodiazepines , alone or in combination with antipsychotics , when compared with placebo or antipsychotics , alone or in combination with antihistamines , to control disturbed behaviour and reduce psychotic symptoms .
Rapid tranquillisation of violent or agitated patients in a psychiatric emergency setting. Pragmatic randomised trial of intramuscular lorazepam v. haloperidol plus promethazine.
BACKGROUND The pharmacological management of violence in people with psychiatric disorders is under- research ed . AIMS To compare interventions commonly used for controlling agitation or violence in people with serious psychiatric disorders . METHOD We r and omised 200 people to receive intramuscular lorazepam ( 4 mg ) or intramuscular haloperidol  ( 10 mg ) plus promethazine ( 25 - 50 mg mix ) . RESULTS At blinded assessment s 4 h later ( 99.5 % follow-up ) , equal numbers in both groups ( 96 % ) were tranquil or asleep . However , 76 % given the haloperidol-promethazine mix were asleep compared with 45 % of those allocated lorazepam ( RR=2.29,95 % CI 1.59 - 3.39 ; NNT=3.2,95 % CI 2.3 - 5.4 ) . The haloperidol-promethazine mix produced a faster onset of tranquillisation/sedation and more clinical improvement over the first 2 h. Neither intervention differed significantly in the need for additional intervention or physical restraints , numbers absconding , or adverse effects . CONCLUSIONS Both interventions are effective for controlling violent/agitated behaviour . If speed of sedation is required , the haloperidol-promethazine combination has advantages over lorazepam
