  • Moderate or severe pain within 6 hours of completion of surgery

Exclusion Criteria:

  • Other oral surgical procedures during the same session except the removal of supernumerary third molars
  • Evidence of nasal congestion, nasal polyps, mucosal lesions of the nostrils, postnasal drip of any etiology or any clinically significant nasal pathology that may affect the absorption of study medication or the assessment of safety
