Outcome Measures

Primary Outcomes (1)

  • Summed Pain Intensity Difference (SPID)

    Categorical pain intensity scale - no pain (0), mild pain (1), moderate pain (2), or severe pain (3) was used for all pain intensity assessments postdose. Time-weighted Sum Pain Intensity Difference (SPID) was calculated by multiplying the Pain Intensity Difference (PID) score at each postdose time point by the duration (in hours) since the preceding time point and then summing these values over 0-24 and 16-24 hours, respectively.

    0 to 24 hours post dose

Secondary Outcomes (5)

  • Total Pain Relief (TOTPAR)

    0-24 hours post dose

  • Summed Pain Intensity Difference at Specific Time Intervals

    0-16 hours post dose

  • Time to First Use of Rescue Medication

    postdose to first use of rescue medication

  • Global Assessment of the Investigational Product as a Pain Reliever

    at 24 hours postdose or immediately before first use of rescue medication

  • Time to Onset of Effect

    from postdose to onset of first perceptible and meaningful pain relief for up to 6 hours

Study Arms (2)

Eligibility Criteria

Age16 Years - 45 Years
Sexall
Healthy VolunteersYes
Age GroupsChild (0-17), Adult (18-64)

You may qualify if:

  • Healthy, ambulatory, male and female volunteers between 16 to 45
  • Scheduled to undergo surgical removal of 1 - 2 impacted third molars, one of which must be at least a partial mandibular bony impaction
  • No use of any analgesics, nonsteroidal anti-inflammatory drugs (NSAIDs), aspirin, any other pain reliever (Over The Counter or prescription), or herbal supplements within 5 days of surgery
  • Have moderate to severe postoperative pain on the Categorical Pain Intensity Scale (a score of at least 2 on a 4 point scale) and a score of \>/= 50 mm on the 100-mm visual analog Pain Severity Rating Scale

You may not qualify if:

  • History of hypersensitivity to naproxen sodium, aspirin (ASA), other NSAIDs, opioid analgesics, and similar pharmacological agents or components of the investigational products, including the placebo
  • Evidence or history of clinically significant hematological, renal, endocrine, pulmonary, gastrointestinal, cardiovascular, hepatic, psychiatric, neurologic diseases, or malignancies
  • Relevant concomitant disease such as asthma (exercise induced asthma is permitted), chronic sinusitis or nasal structural abnormalities causing greater than 50 percent obstruction (polyposis nasi, marked septal deviation) that can interfere with the conduct of the study
  • Current or past history of bleeding disorder(s)
  • History of gastrointestinal bleeding or perforation, related to previous NSAID therapy. Active, or history of recurrent peptic ulcer/hemorrhage (two or more distinct episodes of proven ulceration or bleeding)
