Overall Analgesic Efficacy - Sum of Pain Intensity Difference and Pain Relief Scores Over Six Hours (SPRID6)
Časové okno: 6 Hours
Weighted Sum of Pain Intensity Difference and Pain Relief Scores Over Six Hours (SPRID6) - pain intensity and pain relief were evaluated using a 0-100 mm visual analog scale (VAS) where 0 = no pain and 100 = very severe pain for pain intensity and 0 = no relief and 100 = complete relief for pain relief. For SPRID6, the total possible minimum value is -300 (worst) and the total possible maximum value is 1200 (best). The weights used in the calculation of weighted sums were equal to the elapsed time (hour) between the time point of interest and the preceding time point.

Time to Confirmed Perceptible Pain Relief
Časové okno: within 6 Hours
Minutes until confirmed perceptible pain relief was achieved. A stopwatch was provided to the subject after ingestion of the study medication. The subject was instructed to stop the stopwatch when they first began to feel any pain relieving effect whatsoever of the drug, that was when they first felt any pain relief. It did not necessarily mean they felt completely better, although they might have, but when they first felt any difference in the pain.
