This study is a prospective, multicenter, open-label randomized, controlled, parallel-group 2-arm phase III non-inferiority trial. Patients with agitation at emergency department will be randomized to two arms of treatment: one experimental arm with intranasal midazolam 5mg (investigational medicinal product), and one control arm with comparator treatment intramuscular loxapine 100mg. The duration of participation for each patient is at least 28 days (+7 days if follow-up not completed on D28). An endpoint Adjudication Committee will be scheduled.
This study is a non-inferiority phase III randomized trial evaluating the effect of intranasal midazolam versus intramuscular loxapine on the rapid tranquilization of agitated patient in emergency department. Intranasal midazolam is safe and may allow a management of extreme agitation state and prevent adverse effects.
