Study summary

This is a Dental Pain Study which will evaluate the analgesic onset, efficacy and safety of 1000 mg acetaminophen as two Test acetaminophen 500 mg tablets, compared with commercial products of acetaminophen 1000 mg administered as two 500 mg caplets, and ibuprofen (IBU) 400 mg following third molar (wisdom tooth) extraction.

Read the detailed description

This is a single-dose, randomized, double-blind, triple-dummy, placebo- and active controlled, parallel-group study to evaluate the analgesic onset, efficacy, and safety profile of Test acetaminophen 1000 mg compared with two commercial products over a six-hour period after third-molar extractions. Subjects will undergo dental extraction of three or four third molars.

What researchers measure

Primary outcomes

  1. Time to first confirmed perceptible pain relief

    Minutes 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 frame: 6 hours

Secondary outcomes

  1. Percentage of subjects with confirmed perceptible relief from 30 minutes to successively earlier minutes in one-minute increments (Test ACM versus placebo)

    Time frame: 30 minutes or less

  2. Risk ratios of confirmed perceptible relief by 10 minutes (Test acetominophen and commercial ibuprofen)

    The risk ratios and confidence intervals for incidence of confirmed perceptible relief of Test ACM divided by commercial IBU will be presented for 10 minutes

    Time frame: 10 minutes or less

  3. Risk ratios of confirmed perceptible relief by 15 minutes (Test acetominophen and commercial ibuprofen)

    The risk ratios and confidence intervals for incidence of confirmed perceptible relief of Test ACM divided by commercial IBU will be presented for 15 minutes

    Time frame: 15 minutes or less

  4. Risk ratios of confirmed perceptible relief by 20 minutes (Test acetominophen and commercial ibuprofen)

    The risk ratios and confidence intervals for incidence of confirmed perceptible relief of Test ACM divided by commercial IBU will be presented for 20 minutes

    Time frame: 20 minutes or less

  5. Percentage of subjects with meaningful relief by 30 minutes

    Time frame: 30 minutes or less

  6. Time to meaningful pain relief

    Minutes 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 frame: 6 hours
