Post-operative Dental Pain
Conditions
Brief summary
To evaluate analgesic onset, efficacy, and safety of 1000 mg acetaminophen administered as two Test Acetaminophen 500 mg tablets (Test ACM) compared with 1000 mg acetaminophen administered as two commercial acetaminophen 500 mg caplets (ACM) and 400 mg ibuprofen administered as two commercial ibuprofen 200 mg liquid-filled capsules (IBU) in the dental pain model following third-molar extractions.
Detailed description
This is a single-dose, randomized, double-blind, placebo- and active- controlled, parallel-group study to evaluate the analgesic onset, efficacy, and safety profile of Test ACM 1000 mg compared with two commercial products over a four-hour period after third-molar extractions. Subjects will undergo dental extraction of three or four third molars.
Interventions
single dose of 2 Test acetaminophen 500 mg tablets
single dose of 2 acetaminophen 500 mg caplets

Percentage of participants with confirmed perceptible relief by 21 minutes. Stopwatch is started after the participant takes the study medication. The participant is instructed to stop the stopwatch when they first begin to feel any pain relief. The perceptible pain relief is confirmed if the participant also stopped the second stopwatch indicating meaningful pain relief. Test acetaminophen 1000 mg and placebo were compared on the percentage of subjects with confirmed perceptible relief starting at 30 minutes and testing successively earlier minutes (29, 28, etc) until the difference was no longer statistically significant. The earliest significant time was identified.
