Efficacy and Safety of Risperidone and Trazodone Monotherapy and Combination Therapy in Critically Ill Patients With Delirium

Withdrawn before enrolling · Phase 4 · Has a placebo group

Conditions studied: Delirium, Agitation

In brief

The purpose of this randomized clinical trial is to determine whether risperidone alone, trazodone alone, or a combination of risperidone and trazodone is superior for the treatment of ICU acquired delirium. The hypothesis is that combination therapy is superior to either agent alone in treating ICU acquired delirium and sustaining delirium free time.
