Outcome Measures

Primary Outcomes (1)

  • Change in depressive symptoms on the Montgomery-Ă…sberg Depression Rating Scale (MADRS)

    Montgomery-Asberg Depression Rating Scale (MADRS) has a range from 0 to 60, where the lower score indicates the better health status. Change in mean total Montgomery Asberg Depression Rating Scale (MADRS) score from the baseline (pre-dose day 1 ), Day 2 and last day of assessments (Day 8 or Day 10)

    8-10 days

Secondary Outcomes (6)

  • A change in depressive symptoms on the Montgomery-Ă…sberg Depression Rating Scale (MADRS) from the baseline (pre-dose on day 1) and 2 hours post-medication administration

    8-10 days

  • Change in Beck Scale for Suicide Ideation

    24 hours

  • Clinician-Administered Dissociative States Scale (CADSS)

    8-10 days

  • Side Effect Rating Scale for Dissociative Anesthetics (SERSDA)

    8-10 days

  • Maximal sedative effects using Modified Observer's Assessment of Alertness and Sedation ( MOAA/S)

    8-10 days

  • +1 more secondary outcomes

Study Arms (2)

Nebulized Midazolam

ACTIVE COMPARATOR

Midazolam used as active comparator. Dosage calculated by body weight at 0.03mg/kg

Drug: nebulized midazolam
