Primary Outcome Measures:
  • Change From Baseline in Brief Psychiatric Rating Scale (BPRS) Total Scores at 72 Hours [ Time Frame: Baseline, 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.

Secondary Outcome Measures:
  • BPRS Agitation Subscale Response at 72 Hours [ Time Frame: 72 hours ]
    The BPRS agitation subscale score was composed of 4 questions (questions 2, 6, 10, 17). The BPRS agitation subscale score was obtained by summing the relevant individual items. Total possible score range=4 to 28. A response was defined as a > 30 percent reduction from baseline in BPRS agitation subscale score.

  • Change From Baseline in BPRS Agitation Subscale Score at 72 Hours [ Time Frame: Baseline, 72 hours ]
    The BPRS agitation subscale score was composed of 4 questions (questions 2, 6, 10, 17). The BPRS agitation subscale score was obtained by summing the relevant individual items. Total possible score range=4 to 28. Change: score at final visit minus score at baseline.

  • Clinical Global Impression-Improvement (CGI-I) Score at 72 Hours [ Time Frame: 72 hours ]
    CGI-I: 7-point clinician rated scale ranging from 1 (very much improved) to 7 (very much worse). Improvement is defined as a score of 1 (very much improved), 2 (much improved), or 3 (minimally improved) on the scale. Higher score = more affected.

  • Change From Baseline in Clinical Global Impressions Severity (CGI-S) Score at 72 Hours [ Time Frame: Baseline, 72 hours ]
    CGI-S: 7-point clinician rated scale to assess severity of subject's current illness state; range: 1 (normal - not ill at all) to 7 (among the most extremely ill patients). Higher score = more affected. Change: score at observation minus score at baseline.

  • Change From Baseline in Behavioral Activity Rating Scale (BARS) at 72 Hours [ Time Frame: Baseline, 72 hours ]
    BARS measures the degree of agitated behavior using a 7-point scale describing increasing levels of activity (1 =difficult or unable to rouse; 2 = asleep but responds normally to verbal or physical contact; 3 = drowsy, appears sedated; 4 = quiet and awake [normal level of activity]; 5 = signs of overt [physical or verbal] activity, calms down with instructions; 6 = extremely or continuously active, not requiring restraint; 7 = violent, requires restraint.

Primary Completion Date: July 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Intramuscular ziprasidone Drug: Intramuscular ziprasidone mesylate
The recommended dose is 10 to 20 mg administered as required up to a maximum dose of 40 mg per day. Doses of 10 mg may be administered every two hours; doses of 20 mg may be administered every four hours up to a maximum of 40 mg/day for 3 days.
