Active Treatment - 180 mcg of Igalmi (dexmedetomidine)
An initial dose of 180 µg of Igalmi as needed for the treatment of agitation over a period of 7 days. In the event of persistent or recurrent agitation, investigators may choose to repeat dose at 90 μg after the 2-hour time point in the absence of dose-limiting adverse events or safety concerns. A maximum of 2 repeat doses will be allowed in a 24-hour period.

- Change From Baseline in the Positive and Negative Syndrome Scale- Excited Component (PEC) Total Score [ Time Frame: Baseline and 2 hours post-dose for all doses administered ]The Positive and Negative Syndrome Scale-Excited Component (PEC) includes 5 items-poor impulse control, tension, hostility, uncooperativeness, and excitement-each of which is rated from 1 (minimum) to 7 (maximum); the sum of these 5 items, the PEC total score, ranges from 5 (absence of agitation) to 35 (extremely severe).
- Clinical Global Impression - Improvement (CGI-I) [ Time Frame: 2 hours post-dose for all doses administered ]The Clinical Global Impression - Improvement (CGI-I) for agitation in response to treatment measures the current level of agitation relative to the level of agitation prior to administration of study intervention. The CGI-I scores range from 1 to 7 with a score of 1 indicating very much improved, and a score of 7 indicating very much worse.
- Incidence of Adverse Events During the Follow-up Period [ Time Frame: Day 8 through Day 10 ]Evaluation of withdrawal phenomenon based on the occurrence of adverse events such as tachycardia, systolic hypertension, nausea, or vomiting and the emergence of any new adverse events on ≥2 consecutive days of the 3-day off-treatment follow-up period.
