Study Summary

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.

Primary Outcome

The PANSS-EC is the Positive and Negative Syndrome Score - Excited Component, which includes 5 items (excitement, hostility, tension, uncooperative, poor impulse control), which are rated from 1 (not present) to 7 (extremely severe); scores range from 5 to 35; mean scores ≥ 20 clinically correspond to severe agitation. This set of items detects differences between drug and placebo when evaluating acute agitation and aggression in psychiatric patients with different psychiatric pathologies (Monto
