Objective:
To review the current role and comparative efficacy of short-acting intramuscular (IM) antipsychotics in the management of acute agitation, in current clinical practice.
Method:
The efficacy and tolerability of IM antipsychotics in the management of acute agitation in current clinical practice were reviewed in the Medline, PubMed, Cinahl Plus, Scopus-v.4 and PsycInfo databases.
Results:
The comparative efficacy of the rapidly-acting IM atypical antipsychotics (olanzapine, ziprasidone and aripiprazole) is similar to that of the typical antipsychotic, haloperidol. IM olanzapine and ziprasidone were associated with fewer extrapyramidal side-effects and had similar cardiac tolerability to IM haloperidol.
Conclusions:
Further studies are required in the ongoing development of contemporary, evidence-based clinical guidelines in acute agitation, including head-to-head comparisons of currently utilized IM atypical antipsychotics, sequential treatment or combinations of medications.
