Summary
Brief summary
Agitated or violent behavior, mostly as a result of serious mental illness and substance misuse constitutes around 10% of the reasons for use of emergency services. The drugs used in such situations should calm patients safely and swiftly. Guidelines, however, are usually statements of consensus and differ on which drugs to use. Some of the new generation antipsychotics are really not only for oral use but also for parenteral use such as olanzapine and ziprasidone. These medications means an advance in rapid manage of acute behavior alterations. By the way, knowledge about antipsychotics profile in agitation and aggressive behavior is limited and few studies compare several drugs in rapid tranquilization. The objective of this study is to compare five options of parenteral (intramuscular) antipsychotics, including olanzapine, ziprasidone, haloperidol, haloperidol plus promethazine and haloperidol plus midazolam as first medication in agitation.
