Primary Outcome Measures:
  • Average Numeric Pain Rating Score (NPRS) Over 48 Hours After Bunionectomy [ Time Frame: Over 48 hours after bunionectomy ] [ Designated as safety issue: No ]
    Pain intensity scores were measured using an 11-point numerical pain rating scale (NPRS) with 0=no pain to 10=worst possible pain


Secondary Outcome Measures:
  • Number of Patients With Perceptible Pain Relief on Day 1 [ Time Frame: 8 hours post single dose ] [ Designated as safety issue: No ]
    Times to onset of Perceptible and Meaningful Relief were determined using the double-stopwatch method.

  • Median Time to Onset of Pain Relief in Patients With Perceptible Pain Relief on Day 1 [ Time Frame: 8 hours post single dose ] [ Designated as safety issue: No ]
  • Number of Patients With Meaningful Pain Relief on Day 1 [ Time Frame: 8 hours post single dose ] [ Designated as safety issue: No ]
    Times to onset of Perceptible and Meaningful Relief were determined using the double-stopwatch method.

  • Median Time to Onset of Pain Relief in Patients With Meaningful Pain Relief on Day 1 [ Time Frame: 8 hours post single dose ] [ Designated as safety issue: No ]
  • Total Pain Relief (TOTPAR) Scores 8 Hours Post Initial Dose of Study Drug [ Time Frame: 8 hourse post single dose ] [ Designated as safety issue: No ]
    Pain relief was rated using a 5-point categorial scale (0=none, 1=a little, 2=some, 3=a lot, and 4=complete) at time of dose (time=0) and over 15 time points afterwards (10, 15, 20, 30, 45, and 60 minutes and at 1.5, 2, 2.5, 3, 4, 5, 6, 7, and 8 hours after the initial dose on Day 1 or until time of re-medication). A score of 0 across all time points would be the lowest (worst) and a score of 60 (4 X 15 time points) would be the highest (best) possible score.

  • Number of Patients With at Least 30% Reduction in Pain Intensity After First Dose of Study Drug [ Time Frame: 8 hours post single dose ] [ Designated as safety issue: No ]
  • Time to Onset of at Least 30% Reduction in Pain Intensity After First Dose of Study Drug [ Time Frame: 8 hours post single dose ] [ Designated as safety issue: No ]
  • Number of Patients Who Required Rescue Medication on Day 1 [ Time Frame: Day 1 ] [ Designated as safety issue: No ]
  • Number of Patients Who Required Rescue Medication on Day 2 [ Time Frame: Day 2 ] [ Designated as safety issue: No ]
  • Number of Patients Who Required Rescue Medication on Day 3 [ Time Frame: Day 3 ] [ Designated as safety issue: No ]
    Day 3 data reflect the use of rescue medication only up to the time of discharge.
