Study Description

The objective of this study is to evaluate the effect of ketamine formalized to be dispensed via inhalation, as an adjunct to concomitant medications and therapies on those with moderate to severe depression currently in an inpatient psychiatric unit. Investigators will examine the effects of nebulized ketamine on depressive symptoms.

This is a prospective double-blind placebo controlled study in which an active placebo, Midazolam, will be used. Participants will commit to either 4 visits or 5 visits depending on which treatment arm they are randomized into. All visits can be done remotely, however, days in which the participant will be dosed will have to be in person. During dosing days, the participant will be monitored for a minimum of two hours. Study participant's vitals will be collected at regular intervals during the observation period.

Adult psychiatry inpatients who are 18 years and older with a diagnosis of moderate to severe depression will be screened for enrollment by the study.
