There is some evidence that haloperidol is an effective treatment for  acute mania .
From the limited data available , there was no difference in overall efficacy of treatment between haloperidol and olanzapine or risperidone .
Some evidence suggests that haloperidol could be less effective than aripiprazole .
BACKGROUND The main objectives in treating mania are to control dangerous behaviour , reduce suicide , produce appropriate acute sedation and shorten the episode of mood disturbance .
Among different drugs , haloperidol has for many years been used in treating psychotic patients , but it has a troublesome side effect profile .
OBJECTIVES To assess the effects of haloperidol for the treatment of mania in comparison with placebo or other active drugs , either as monotherapy or add-on treatment .
A controlled Nordic multicentre study of zuclopenthixol acetate in oil solution, haloperidol and zuclopenthixol in the treatment of acute psychosis
Zuclopenthixol acetate — a new injectable formulation with a duration of action of 2–3 days — was compared with conventional intramuscular and oral formulations of haloperidol and zuclopenthixol in the initial treatment of acutely disturbed , psychotic patients . The patients were stratified into 3 diagnostic categories : acute psychoses ( 48 patients ) , mania ( 22 patients ) , and exacerbation of chronic psychoses ( 73 patients ) . The patients were rated on the Brief Psychiatric Rating Scale ( BPRS ) , the Bech‐Rafaelsen Mania Rating Scale ( brmas ) ( only manic patients ) and globally on the Clinical Global Impression ( CGI ) . The study was an open , r and omized multicentre trial with a 6‐day treatment period . The zuclopenthixol acetate patients received 1–4 doses , the haloperidol patients 1–26 and the zuclopenthixol patients 1–22 doses . The assessment s on the CGI showed that all 3 treatments caused a clear reduction of the severity of illness scores in all 3 diagnostic categories , with no differences between treatments . The ratings of the acute and chronic psychotic patients on the BPRS also showed significant reductions in scores with no differences between treatments . All 3 treatments caused a rapid remission of symptoms on the BRMAS .  Haloperidol  induced hypokinesia in significantly more patients than zuclopenthixol acetate after 24 h. Later there were no significant differences between treatments . Zuclopenthixol acetate fulfils many desires for an amended neuroleptic formulation for the initial treatment of acutely disturbed psychotic patients
