Measure Description |
Time Frame |
|---|---|---|
|
Time weighted sum of pain intensity difference from 0-6 hours (SPID 0-6)
Time Frame: 6 Hours
|
Time weighted sum of pain intensity difference scores from baseline over 6 hours.
Pain intensity was evaluated using a 0-10 pain intensity numerical rating scale (PI-NRS) where 0 = no pain and 10 = very severe pain

|
Time to meaningful pain relief
Time Frame: Within 6 Hours
|
Minutes until meaningful pain relief are achieved.
Stopwatch is started after the subject takes the study medication.

|
|

|
Minutes until confirmed first perceptible pain relief are achieved.
Stopwatch is started after the subject takes the study medication.
