Primary Outcome Measures:
  • SPRID0-3: Time-weighted sum of pain relief rating scores combined with pain intensity difference scores over the 3 hour post-dose evaluation period for the comparison of Ibuprofen Sodium versus placebo [ Time Frame: over 3 hours ] [ Designated as safety issue: No ]
  • Time to onset of "meaningful" relief for the comparison of Ibuprofen Sodium tablets versus Ibuprofen tablets [ Time Frame: 0 to 3 hours ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • All pairwise comparisons other than those tested for primary comparisons will be evaluated for these parameters: [ Time Frame: 3 hours ] [ Designated as safety issue: No ]
  • Time to onset of "meaningful" relief [ Time Frame: 0 to 3 hours ] [ Designated as safety issue: No ]
  • Time to onset of "first perceptible" relief, confirmed by "meaningful" relief [ Time Frame: 0 to 3 hours ] [ Designated as safety issue: No ]
  • Pain Relief Rating (PRR): scored on the 5 point Categorical Pain Relief Rating Scale (0=No relief to 4=Complete relief) [ Time Frame: 1, 2 & 3 hours post-dose ] [ Designated as safety issue: No ]
  • Pain Intensity Difference (PID): scored on the 4 point Categorical Pain Severity Rating Scale (0=None to 3=Severe) [ Time Frame: 1, 2 & 3 hours post-dose ] [ Designated as safety issue: No ]
  • The sum of pain relief rating and pain intensity difference scores (PRID) [ Time Frame: 1, 2 & 3 hours post-dose ] [ Designated as safety issue: No ]
  • Sum of pain intensity difference scores [ Time Frame: over 2 & 3 hours ] [ Designated as safety issue: No ]
  • Time-weighted sum of pain relief rating scores [ Time Frame: over 2 & 3 hours ] [ Designated as safety issue: No ]
  • Time-weighted sum of pain relief rating scores combined with pain intensity difference scores [ Time Frame: over 2 & 3 hours ] [ Designated as safety issue: No ]
  • The cumulative proportion of subjects achieving "meaningful" and "first perceptible" relief (confirmed by "meaningful" relief) [ Time Frame: 0.5, 1, 2 & 3 hours ] [ Designated as safety issue: No ]
  • Duration of relief, as measured by the time to treatment failure [ Time Frame: 0 to 3 hours ] [ Designated as safety issue: No ]
  • The cumulative proportion of treatment failures [ Time Frame: 1, 2, & 3 hours post-dose ] [ Designated as safety issue: No ]
  • The cumulative proportion of subjects achieving "complete" relief [ Time Frame: 1, 2, & 3 hours post-dose ] [ Designated as safety issue: No ]
