Outcome Measures

Primary Outcomes (1)

  • Change From Baseline in Brief Psychiatric Rating Scale (BPRS) Total Scores at 72 Hours

    BPRS is an 18-item clinician rated scale with 11 general symptom items, 5 positive-symptom items, and 2 negative symptom items scored on a 7-point scale (1=not present and 7=extremely severe), with higher score indicating greater severity of symptom. Total possible score range=18 to 126. Change: score at final visit minus score at baseline.

    Baseline, 72 hours

Secondary Outcomes (5)

  • BPRS Agitation Subscale Response at 72 Hours

    72 hours

  • Change From Baseline in BPRS Agitation Subscale Score at 72 Hours

    Baseline, 72 hours

  • Clinical Global Impression-Improvement (CGI-I) Score at 72 Hours

    72 hours

  • Change From Baseline in Clinical Global Impressions Severity (CGI-S) Score at 72 Hours

    Baseline, 72 hours

  • Change From Baseline in Behavioral Activity Rating Scale (BARS) at 72 Hours

    Baseline, 72 hours

Study Arms (2)

Intramuscular ziprasidone

EXPERIMENTAL
Drug: Intramuscular ziprasidone mesylate

Intramuscular haloperidol

ACTIVE COMPARATOR
Drug: Intramuscular haloperidol

Interventions
