NCT01960114

Brief Summary

The purpose of the study is to evaluate the efficacy and safety of acetaminophen ER 1500 mg (two 750 mg tablets) over 10 to 12 hours in the dental pain model following third molar extraction(s) and to evaluate the pharmacokinetics of acetaminophen ER 1500 mg (two 750 mg tablets) in a sub-group of subjects.

Outcome Measures

Primary Outcomes (1)

  • Time Weighted Sum of Pain Intensity Difference (PID) Over 10 Hours (SPID 0-10)

    Time weighted sum of pain intensity difference scores from baseline over 10 hours. Pain intensity was evaluated using a 0-10 numerical rating scale (NRS) where 0 = no pain and 10 = very severe pain. SPID 0-10 = 0.25 x (PID at 15 min + PID at 30 min + PID at 45 min + PID at 60 min + PID at 75 min + PID at 90 min) + 0.5 x (PID at 120 min) + PID at 3 h + PID at 4 h + PID at 5 h + PID at 6 h + PID at 7 h + PID at 8 h + PID at 9 h + PID at 10 h.

    10 Hours

Secondary Outcomes (4)

  • Time to Confirmed First Perceptible Pain Relief

    Within 12 Hours

  • Time to Meaningful Pain Relief

    Within 12 Hours

  • Duration of Pain Relief

    Within 12 Hours

  • Patient Global Evaluation
