Abstract

OBJECTIVE:

Efficacy and tolerability of risperidone oral solution (RIS-OS) and olanzapine orally disintegrating tablet (OLZ-ODT) were compared for the treatment of acute psychotic agitation.

METHOD:

During a 2-month period, patients scoring > or =15 on the Excited Component for Positive and Negative Syndrome Scale (PANSS-EC) were assigned to treatment with OLZ-ODT (n=34) or RIS-OS (n=53) on psychiatric emergency situations, and assessed every 15 min.

RESULTS:

Two (OLZ-ODT and RIS-OS) by five (0-, 15-, 30-, 45- and 60-min time points) repeated-measures analysis of variance revealed only a significant main effect of time course on PANSS-EC (F=82.2, P<.0001). No differences in the number of patients receiving additional injection due to worsening were found (OLZ-ODT, 11.8%; RIS-OS, 9.4%). No differences in rate of extrapyramidal symptoms and patient satisfaction with assigned treatment were found. However, patients in the OLZ-ODT group recovered significantly more from tachycardia than those in the RIS-OS group (t=2.17, P=.03).

CONCLUSION:

OLZ-ODT and RIS-OS treatments yielded similar improvements in acutely agitated patients who accepted oral medication. However, on one physiological parameter (i.e., tachycardia) OLZ-ODT might be superior to RIS-OS. Physiological indicators may also be useful for measuring levels of agitation.
