Official title

A Comparison Study of the Efficacy of a Rapid Titration of Quetiapine and Haloperidol in Agitated Adults in an Emergency Setting.

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

In the Psychiatric Emergency Room, agitated patients are treated routinely with an I.M. Haloperidol "cocktail" (Haloperidol 5 mg, Lorazepam 2 mg, Cogentin 2 mg), which has proved to be an effective treatment. However, since it is an intramuscular injection, it is more complicated and perhaps less acceptable to patients as well as more likely to cause EPS (extrapyramidal symptoms). Of late in our emergency room, we started using high dose Quetiapine 300 mg PO to replace the "cocktail" for treating agitation. It has shown promising results.
