Brief summary

This is a dental pain study evaluating the efficacy and safety of a single dose of test acetaminophen (ACE) (1000 mg) compared to commercial acetaminophen (1000 mg), ibuprofen (IBU) (400 mg), and placebo over a 6 hour period. Subjects will undergo dental extraction of three or four third molars.

Interventions

DRUGAcetaminophen (ACE) (1000 mg)

2 Test ACE 500 mg tablets taken orally one time

DRUGCommercial ACE (1000 mg)

2 ACE 500 mg caplets taken orally one time

DRUGCommercial Ibuprofen (IBU) (400 mg)

2 IBU 200 mg soft-gels taken orally one time

DRUGPlacebo

2 placebo caplets for acetaminophen taken orally one time

Design outcomes

Primary

MeasureTime frameDescription
Time weighted sum of pain intensity difference from 0-6 hours (SPID 0-6)6 HoursTime 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

Secondary

MeasureTime frameDescription
Time weighted sum of pain intensity difference from 0-4 hours (SPID 0-4)4 HoursTime weighted sum of pain intensity difference scores from baseline over 4 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 reliefWithin 6 HoursMinutes until meaningful pain relief are achieved. Stopwatch is started after the subject takes the study medication. The subjects are instructed to stop the stopwatch when the relief from the starting pain is meaningful to them.
Time to first perceptible pain reliefWithin 6 HoursMinutes until first perceptible pain relief is achieved. Stopwatch is started after the subject takes the study medication. The subject is instructed to stop the stopwatch when they first begin to feel any pain relief.
Time to confirmed first perceptible reliefWithin 6 HoursMinutes until confirmed first perceptible pain relief are achieved. Stopwatch is started after the subject takes the study medication. The subject is instructed to stop the stopwatch when they first begin to feel any pain relief. The first perceptible pain relief is confirmed if the subject also stopped the second stopwatch indicating meaningful pain relief.
Time weighted sum of pain relief from 0-4 (TOTPAR 0-4)4 hoursTime weighted sum of pain relief scores over four hours. Pain relief was evaluated using a 0-10 pain relief numerical rating scale (PR-NRS) where 0 = no relief and 10 = complete relief
Time weighted sum of pain relief from 0-6 (TOTPAR 0-6)6 hoursTime weighted sum of pain relief scores over six hours. Pain relief was evaluated using a 0-10 pain relief numerical rating scale (PR-NRS) where 0 = no relief and 10 = complete relief
