Population: Full Evaluable Population: Participants who received study drug infusion for at least 5 hours and had available PK data were included in the full evaluable population. This was the primary population for PK and PD analyses.

RSS Score range from 1 to 6: 1. Patient is anxious and agitated or restless, or both. 2. Patient is cooperative, orientated and tranquil. 3. Patient responds to command only. 4. Patient exhibits brisk response to light glabellar (between the eyebrows) tap or loud auditory stimulus. 5. Patient exhibits a sluggish response to light glabellar tap or loud auditory stimulus. 6. Patient exhibits no response to stimulus.
