Primary Outcome Measures :
  1. Time from first IM medication administration to adequate sedation which is defined as RASS less than or equal to -1. [ Time Frame: 1 day ]
    Measured using Richmond Agitation Sedation Scale (RASS) in each arm

Secondary Outcome Measures :
  1. Percentage participants with adverse events in each arm [ Time Frame: up to 4 days ]
    measured by AE collection in each arm

  2. Percentage of participants in each arm requiring rescue medications between 5 and 30 minutes (at 5 minutes interval) after study medication(s) administration by count. [ Time Frame: 1 day ]
    measured by rescue medication administration

  3. Percentage of participants in each arm experiencing sedation outcomes as defined by the TROOPS criteria [ Time Frame: 1 day ]
    measured using Tracking and Reporting Outcomes of Procedural Sedation (TROOPS) criteria

  4. Percentage of participants with neuroleptic malignant syndrome events within 24 hours of enrollment of each arm. [ Time Frame: 1 day ]
    measured by occurrence of neuroleptic malignant syndrome

  5. Percentage of participants experiencing pre-hospital use of force by police in this participant population, by number and type of restraint. [ Time Frame: 1 day ]
    measured by police account at study enrollment

  6. Participant experience survey outcomes. [ Time Frame: 1 day ]
    measured using Participant Experience Survey

  7. Study Nurse Experience survey outcomes. [ Time Frame: 1 day ]
    measured using Study Nurse Experience Survey

  8. Effectiveness of Blinding survey outcomes [ Time Frame: 1 day ]
    measured using Effectiveness of Study Drug Blinding Survey
