Time to Meaningful Pain Relief
Minutes until meaningful 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 the relief from the starting pain was meaningful to them.
Time to Confirmed Perceptible Pain Relief
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.
Duration of Analgesia - Time to Rescue
Minutes until rescue medication was given.
Rescue Rates Through Four Hours
Percentage of subjects using rescue medication.
Rescue Rates Through Six Hours
Percentage of subjects using rescue medication.
Percentage of Subjects With >50% of the Maximum Possible TOTPAR6 Score
Percentage of Subjects with >50% of the Maximum Possible TOTPAR6 Score - pain relief was evaluated using a 0-100 mm visual analog scale (VAS) where 0 = no relief and 100 = complete relief with a highest possible score of 600 so >50% is >300 out of 600

Sum of Pain Intensity Difference and Pain Relief Scores (PRID) at 120 Minutes
Description
Sum of PID and PAR Scores (PRID) at each Assessment Time point - 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
Time Frame
120 Minutes
Title

Time Frame
180 Minutes
Title
Sum of Pain Intensity Difference and Pain Relief Scores (PRID) at 240 Minutes
Description
Sum of PID and PAR Scores (PRID) at each Assessment Time point - 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
Time Frame

Title
Sum of Pain Intensity Difference and Pain Relief Scores (PRID) at 300 Minutes
Description
Sum of PID and PAR Scores (PRID) at each Assessment Time point - 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
Time Frame
300 Minutes
Title
Sum of Pain Intensity Difference and Pain Relief Scores (PRID) at 360 Minutes
Description
Sum of PID and PAR Scores (PRID) at each Assessment Time point - 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
Time Frame
360 Minutes
Title
Time to Meaningful Pain Relief
Description
Minutes until meaningful 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 the relief from the starting pain was meaningful to them.
Time Frame
within 6 Hours
Title
Time to Confirmed Perceptible Pain Relief
Description
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.
Time Frame
within 6 Hours
Title
Duration of Analgesia - Time to Rescue
Description
Minutes until rescue medication was given.
Time Frame

Title
Rescue Rates Through Four Hours
Description
Percentage of subjects using rescue medication.
Time Frame
through 4 Hours
Title
Rescue Rates Through Six Hours
Description
Percentage of subjects using rescue medication.
Time Frame
through 6 Hours
Title
Percentage of Subjects With >50% of the Maximum Possible TOTPAR6 Score
Description
Percentage of Subjects with >50% of the Maximum Possible TOTPAR6 Score - pain relief was evaluated using a 0-100 mm visual analog scale (VAS) where 0 = no relief and 100 = complete relief with a highest possible score of 600 so >50% is >300 out of 600
Time Frame
6 Hours
Title
