Naproxen, ibuprofen and placebo in the treatment of pain secondary to dental impaction surgery

Trial purpose

This single center, single-dose randomized, double-blind, parallel,
placebo- and active- controlled study was designed for 175 evaluable
subjects. Subjects were randomly assigned to one of the 3 treatment
groups in the ratio of 2:2:1 (naproxen 187.5 mg [NAP187.5] or
ibuprofen 200 mg [IBU200] or placebo). Pain response was evaluated
immediately prior to administration of study drug, 1 hour and hourly
thereafter up to 12 hours. Pain intensity and pain relief were
measured on categorical scales and subjects were asked if their pain
was at least half gone from baseline at each time point. Subjects
remained in the study for up to 12 hours. Back up analgesic
medications was available for those subjects who experienced
insufficient pain relief from the study medication.

Primary Outcome

  • Computing the total pain relief (TOTPAR) scores for each subject
    date_rangeTime Frame:
    at 6, 8, 10 and 12 hours

Secondary Outcome

  • Summed pain intensity difference (SPID) scores
    Based on a categorical scale
    date_rangeTime Frame:
    at 6, 8, 10 and 12 hours
  • The proportion of time points when the subject reported starting pain at least one-half gone
  • Peak PID: maximum pain intensity difference (PID) score
  • Peak relief: maximum pain relief score
  • The time to onset of pain relief
    Time interval between taking study medication and onset of at least "some" pain relief (as indicated by a score of at least 2 on a 5-point scale)
  • The proportion of subjects taking backup medication
  • The time interval between taking study medication and taking backup medication
