AGItated Patients Management: intraNASAL Midazolam vs Intramuscular Loxapine, a Randomized Non Inferiority Trial

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.

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.

Inclusion Criteria:

• Age 18 to 60 years;
• Agitated Patient whose somatic or psychiatric aetiology cannot be diagnosed in an emergency situation and who need a sedation in a hospital emergency setting due to the presence of unmanageable agitation with 3 major criteria.

Major criteria :

Agitation Pain Tolerance Tachypnea ( fr > 20)

And 1 minor criteria among :

Sweating Tactile Hyperthermia Medical care Non compliance Lack of tiring Unusual Strenght Inappropriately clothed, nudity

• Medical insurance The protocol can start if the THREE major inclusion criteria and ONE of the minor inclusion criteria are checked PRESENT and ALL the non-inclusion criteria are checked no.

Exclusion Criteria:

Subjects who meet any of the following criteria will be excluded from randomization into the study:

• Pregnancy

  • In combination with dopamine agonists except levodopa (amantadine, bromocriptine, lisuride, pergolide, piribedil, ropinirole, cabergoline, pramipexole, apomorphine) outside the patient with Parkinson's disease
  • Individuals with a history of cerebrovascular accident or epilepsia
  • Individuals in whom a significant elevation of blood pressure would constitute a serious hazard, such as patients with significant hypertension;
  • Individuals with severe cardiac decompensation
  • Patients with severe respiratory failure or acute respiratory depression
